RELEASE NOTES
WAR FTP DAEMON for Win95/NT
Get the latest update at: http://www.jgaa.com
I have now started to work on the next major version (2.0)
of the server. Almost all the code will be rewritten to
improve the design and flexibility, and to make it even faster
to add new features.
Because of this there will not be more features in the
current major versioin (1.*), but bugfixes will be done
until version 2.0 is released.
Please join the newsgroup alt.comp.jgaa if you want to discuss
the features and be up to date on the development of version 2 :-)
If your news provider dont carry this group today, make a call
and ask them to. It will normally take only a day or two before
they open it.
You can also join the warftpd mailing list or update notification
lists. Send a mail to info@jgaa.ldp.no (auto-responder) for more
information.
KNOWN PROBLEMS
The server does not work with the current version
of Trumpet Winsock for Win95.
The user interface does not look very good under NT 3.51.
The menu are overwritten by the toolbar, and sometimes the
list boxes will not be visible. These problems will be
resolved in version 2.0.
NT SERVICE:
* The service will hang if you use a user account
that is not in the NT "administrator" group.
* You will not be able to log out from the console
without stopping the service if you have the
SITE SHOW option enabled. (Options/NT tab).
This is due to a bug in MFC. I have not found a
work-around.
If you need to have the server auto-start when the
system boot, *and* need the SITE SHOW option enabled,
stop the service and reboot rather than logging out.
* I have experienced a few times that it has been impossible
to log in to NT 4 with the same user account that caused
the server to crash (when I logged off and the SITE SHOW
was enabled). To reset the user environment (and enable
NT login), log on to NT as another user with ADMINISTRATOR
privilegies and load/save the user in the NT User Manager.
This will clean up the mess (probarbly somewhere in the
registery) and solve the problem.
This looks like a NT 4 bug to me...
The server will crash rather than playing sounds on some (NT 3.51 ??)
systems. If the server is unstable, disable the sound option
(Options/Sound tab).
-------------------------------------------
V. 1.65 Release version Apr. 24 1997
-------------------------------------------
ADDED Option to handle brain dead ISP's.
Some ISP's deny use of FTP servers for their PPP
users. You can now bypass this restriction by
using another port than 21, and check the "Fool
brain dead ISP's" checkbox in /Options/FTP
ADDED New method for multimoming/mutlihosting. Previous
versions of War FTP Daemon handled this by adding
@ipNum after the user names. This still works, but you
can now also set up several instances of the server
on the same machine, each listening to different IP
numbers (the IP numbers must be assigned to the machine).
Use the /Options/Serber Name/Limit access... field to
enable this.
Note: Each virtual server must be installed in it's own
directory, and VfSys paths (if used) must _not_ overlap.
CHANGE The startup therad for the server is now processing messages
from the operating system. (Since the server can be used as a
NT service, the startup thread is not used by the server.)
This will prevent some problems when programs broadcast messages
to all running programs and expect an answer.
BUGFIX sysmsg@Ipname.txt files was not shown correctly on
multihoming systems.
Fixed.
BUGFIX On some systems the Options dialog did not work.
Fixed.
-------------------------------------------
V. 1.63x Experimental version Apr. 22 1997
-------------------------------------------
ADDED Option to disable write protection on files open for
FTP send. (See Options/FTP)
-------------------------------------------
V. 1.62 Release version Apr. 20 1997
-------------------------------------------
BUGFIX Resume was broken when files was copied from CD-ROM.
Fixed.
-------------------------------------------
V. 1.61 Release version Apr. 19 1997
-------------------------------------------
Several bugs are traced and fixed. The server should now be unable
to crash on release versions of Windows95 and NT. There are reported
a few problems with Memphis and NT 5. I have asked Microsoft to provide
me with copies of these systems in order to trace and fix this.
The installastion script in 1.55 had a problem where some system dll's was
removed in the Windoes system directory and replaced with copies in the
server install dir. This is now fixed, so that new system dll's are copied
to the Windows system directory.
ADDED Option to copy files from CD-ROM and network drives to a local temp
dir before transmitting the file. (This has been on the "most wanted
features" list for a while.)
The server will start a new therad to perform the copying the first
time the copy operation is needed. This thread will serve all requests
to copy a file from a slow drive to a temp dir. This design ensures that the
server will handle all ongoing transfers at full speed, and also ensure
that only one file is copied from a CD-ROM drive or CD-ROM changer (jukebox)
at one time. Copying more than one file from a CD-ROM will slow down the
performance significantly. The one-file-at-the-time design will also
reduce the load on the local network when files are copied from other
machines prior to download.
As soon as the file is copied, the transfere starts at full speed from
the local harddisk.
ADDED Command to abort an ongoing file transfer from the server console.
Right click on the user and select "Stop transfer". No confirmation dialog
will pop up. If a transfer is open it will be aborted.
ADDED Macros in the log file name. See the help section about the log
file for details.
-------------------------------------------
V. 1.60x Experimental version Mar. 31 1997
-------------------------------------------
BUGFIX The firewall support caused WSAEADDRINUSE error
messages, and problems with opening the data connection.
Fixed.
-------------------------------------------
V. 1.59x Experimental version Mar. 31 1997
-------------------------------------------
BUGFIX The spy option did not work in 1.57/58
Fixed
-------------------------------------------
V. 1.58x Experimental version Mar. 29 1997
-------------------------------------------
BUGFIX A few UNKNOWN EXCEPTION's are removed
BUGFIX A missing assignment to port 20 on the server side of file
transfers caused problems with firewalls.
Assumed fixed.
-------------------------------------------
V. 1.56x Experimental version Feb. 17 1997
-------------------------------------------
ADDED ODBC logging. The ODBC log feature adds an option to log
file transfers to an MS-SQL server through an ODBC
connection. You must have MS-SQL server installed before
you enble this option.
Steps to install the ODBC log feature:
1) Copy CODBCLog.dll into the War FTP Daemon directory
2) Modify ODBCLog.ini to your preferences.
[ODBC]
Database=WarLog
Table=LOG
DoCreate=1
User=sa
Pwd=
ODBC name=WarFTPD
3) Create a new empty SQL database, with the name you have
choosen as "Database".
4) Create a new ODBC definition on the machine running the
FTP server with the name you have choosen as "ODBC name".
Set the "default database" to the name of the database.
5) Make sure that the SQL user name and password in the .ini
file are valid.
Start the War FTP Daemon. The FTP server will try to create a new
table named "LOG" in the fresh database each time it start's up,
until the table is created. It will then automatically set the
flag "DoCreate" to 0.
In order to remove the option, simply delete the file CODBCLog.dll.
ADDED Better protection against GPF problems. The server should now be
unable to crash. If a fatal error occur, the session that cause the
error might halt (from the users point of view), but the server should
remain online. Memory is not released when fatal error occurs, so this
can lead to a significant "memory leak" over some time.
If you see complaint's in the server log about CAUGHT UNKNOW EXCEPTION ...
restart the server or (if possible) reboot the machine. The error
handler is ment to keep the server alive until an operator can deal
with the problem, not as a solution to run a faulty system over a long
period of time.
-------------------------------------------
V. 1.55 Relese version Feb. 11. 1997
-------------------------------------------
ADDED Support for async chat when used with the War FTP Client.
Implementation details: Async chat is enabled with the
SITE CHAT MODE=ON PROTOCOL=ASYNC REPLYCODE=nnn where nnn
is a number in range 200 - 299.
When enabled, the server send messages to the FTP client
as they apper, without delay, as normal command replies.
The message is identified by the number 'nnn'.
It is the responsibility of the FTP client to choose
a unique number so that it can seperate chat lines from
normal command replies.
ADDED SITE PASS <new password> command. This allow users to
change their passwords online.
BUGFIX If a password was changed on a user account imported from
Serv-U, the password autentication would fail.
Fixed.
-------------------------------------------
V. 1.54x Relese version Jan. 10. 1997
-------------------------------------------
ADDED Command line option to change the physical paths in
all the users FileAccess tab. This option is designed
to be used after the physical layout of the file
system has changed, like when you have added a new
disk drive.
Syntax: war-ftpd -ReplacePathFrom C:\ -ReplacePathTo F:\
The sample above will replace *all* user paths starting with
C:\ with F:\. C:\pub\ftp will i.e. now be F:\pub\ftp. The server
does not do any validiation of thhe changes.
If you just use the -ReplacePathFrom without -ReplacePathTo,
any path matching the ReplacePathFrom argument will be permanently
removed from the internal lists.
MAKE A BACKUP COPY OF WARFTPDAEMON.DAT BEFORE YOU USE THIS
OPTION. THE CHANGES WILL BE PERMANENT.
The code below shows the implementation of this feature:
(You don't need to understand the code in order to use
this feature, but c++ programmers will get a better
understanding of thow it works by looking at the code.
if (SubstOldPath.GetLength())
{
if (!strnicmp(Me.m_Path, SubstOldPath, SubstOldPath.GetLength()))
{
if (SubstNewPath.IsEmpty())
continue; // Path is to be deleted.
LPCSTR p = Me.m_Path;
p += SubstOldPath.GetLength();
CString cBuf;
cBuf = SubstNewPath;
cBuf += p;
Me.m_Path = cBuf;
}
}
ADDED Temporary user accounts. This feature is designed
to be used with automation tools, (like a CGI) to
allow one-time-access to files. It was originally
developed for the distribution of the War FTP Daemon
version 2 source code. In that case a CGI bin is called
from a web page. The CGI creates the temporary user
account and redirects the browser to the ftp server.
The benefit with this method is that warez traders can not
trade a FTP account. The account will be deleted the first
time it is used. The code below demonstrates how to use this
feature:
// Create tmp alias
char buf[32], *p;
int len = 16;
p = buf;
srand( (unsigned)time( NULL ) );
while(len)
{
i = rand();
if (isalpha((i & 0xff)))
{
*(p++) = (char)(i & 0xff);
--len;
}
}
buf[16] = 0;
WritePrivateProfileString("tmp Alias", buf, "TheRealUserName","WarFtpdAlias.ini");
Sleep(1000);
printf("HTML/1.1%cLocation: ftp://%s:password@you.ftp.com/warsrc.zip%c%c%c",10, buf, 10,10,10);
As you might spot, the "tmp" userid is actually just a
temporary nick to a real (permanent) user account.
However, the FTP user will never know the identity
of this account (unless you expose it by using the userid
in some macro whne th euser logs on, or if you enable the
SITE WHO command.
The ini file will be created automatically in the windows system
catalog if you use the code above. This is also where the server
will look for it.
-------------------------------------------
V. 1.52 Relese version Oct. 28. 1996
-------------------------------------------
BUGFIX If a user was kicked with the "ban IP" option checked
before he had logged on, the server would crash.
Fixed.
-------------------------------------------
V. 1.51 Relese version Oct. 28. 1996
(Upgrade from 1.50 only)
-------------------------------------------
CHANGE ABOR will now send file xmit termination message
if a file transfer is open.
CHANGE The server will now recognize Fetch's ABOR sequence.
BUGFIX 2 bugs that caused GPF is fixed.
-------------------------------------------
V. 1.50 Relese version Oct. 24. 1996
-------------------------------------------
ADDED Option to mount network drives when the server runs as a
NT service.
ADDED $g (group name) and $c (class name) macros to the upload
verification module.
ADDED To help the ppp users to announce their current IP number,
the server will write the IP number reported by
Winsock to the file "CurrentIPNumber.txt" each time it
goes online.
UPDATED Online help.
CHANGE The server will not accept more than 5 ls therads. This
is done to avoid a MS bug in WaitForMultipleObjects()
that else would generate a huge memory leak.
This will not affect the performance of the server, unless
5 or more users are issuing recursive directory listings
at the same time.
BUGFIX Code is borrowed from version 2 of the server to prevent a rare
GPF failure when users disconnect while up/download is in
progress.
BUGFIX The connection counter was decrementing by one if a user was
denied by absolute IP. That would lead to negative connection
numbers.
Fixed.
BUGFIX Fixed a bug in the Serv-U import filter that would lead to
"Access denied to home directory" errors.
Note: You must still verify the File Access tab for each
user/group imported as War sometimes creates duplicate
entries.
BUGFIX The timezone conversion functions sometime caused illegal
dates on virtual files. This could confuse Cute-FTP so that
the files was not displayed in the directory listing.
Fixed.
BUGFIX (NT) The event log will now resolve the correct message text.
BUGFIX The server could in some situations close incoming file transfers
before the files were completly uploaded.
Fixed.
BUGFIX Resume of upload should now work.
-------------------------------------------
V. 1.32x experimental BETA Oct. 15. 1996
-------------------------------------------
The server now use the MSVC 4.2b with update patch from MS. This
includes new dll's. (again...)
ADDED SITE SHOW command to display the server console when the
server is running as a system service under NT. The server
must be configures to run in "Interactive" service mode
for this to work, and NT must allow interactive services.
This new command can be used to configure the server when
it runs as a service.
Note: You must log in to the server from a FTP client
as a FTP user in the class "sysadmin". Then issue the
QUOTE SITE SHOW command (or define a custom command
if you use Cute-FTP) to bring up the server console.
THE SERVER WILL NOT DISPLAY THE TASKBAR ICON. This is
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
done by purpose since the service don't "belong" to the
user currently logged on to the NT desktop.
BUGFIX I traced down a bug in the pattern matching function that
might be the cause of the reported problems with banned
files and upload verification. I *hope* this is fixed.
BUGFIX In 1.31x the server would not report the correct number
of users online.
Fixed.
-------------------------------------------
V. 1.31x experimental BETA Sept. 29. 1996
-------------------------------------------
The server now use the MSVC 4.2a with update patch from MS. This
includes new dll's.
BUGFIX Now allows '@' in user names to allow multihoming
users (was disabled a few releases ago...)
TESTED I had a report that banned files did not get banned,
ie. *.txt in the banned list would still allow text
files to be uploaded.
I found no bugs here. Make sure that banned files
are added to the correct level. If you ban file names
on user "garfield", the banning will only apply for
this user. In general, banned files should be
defined on the "default" level.
TESTED There is reported to be a memory leak in 1.30x. I have
not been able to find any such leak, so it might be
bugs in the MFC libraries. The libraries are updated
in 1.31x. The only known memory leak are a due to a
bug in MFC when a thread is waiting for more than
8 events. This can be avoided by using 5 or less
ls-threads.
-------------------------------------------
V. 1.30x experimental BETA Sept. 17. 1996
-------------------------------------------
I have tried to track down a bug that cause the server to
crash in the sockets subsystem - with no luck.
To help out some of you that are waiting for the bugfixes
below I release this version now. New versions with more
features and improvements can be expected in the *near*
future.
ADDED Option to turn reverse DNS lookup on/off. (It is set
off by default).
CHANGE Now using MSVC++ 4.2. Several new dll's in the
distribution.
CHANGE The server will now use the *modification* date
as file date. In previous versions it used the
creation date.
BUGFIX Deletion of files sometimes failed when the
virtual file system was used because the server
forgot to delete empty .Index.txt files.
Fixed.
BUGFIX The server would shut down file transferes if the
"Go offline when ready" button was pressed.
Fixed.
BUGFIX Sometimes the server would move files into the
servers home directory when it was told to
*rename* the file.
Fixed.
BUGFIX Some fixes in VfSys when loading/flushing empty
directories.
BUGFIX War would not show directories/files if the
first file/dir in a directory was denied
to the user due to UNIX/VfSys permissions.
Fixed.
------------------------------------------
V. 1.29x experimental BETA August 4. 1996
------------------------------------------
ADDED ls -d option to support ncftp "get -R"
ADDED Copy User and Rename User in the Security
tab (User maintainance).
Copy User will create a new user with
all the properties of the selected user,
except username and password.
ADDED Auto-rescan option for VfSys to ease dupe
checking on systems where files might be added
from other applications (like BBS systems).
The scanning will be done in a defined
time interval, and only when no users are
listing directories.
Note: During the rescan the server will
"hang". I could have added a thread to
do the scanning, but the disk/IO is so intense
during this operation that another tread would
just have slowed down the overall performance.
ADDED [$dirmsg] macro to display the directory change
message. This macro is automatically called when
the user log in and when he change directory.
CHANGE Help via F1 was disabled in release 1.26x.
It is now re-enabled.
CHANGE Usernames are now restricted to 'a' - 'z' and
'0' - '9'. Other letters will be refused.
The current user database is not affected.
CHANGE If the "Go offline when ready" checkbox on the
console is checked the user will be logged off
as soon as the current file transfer is
completed.
CHANGE When the Upload Veryfier renames a file, it is
now updated in VfSys.
CHANGE If a user is rejected due to a banned IP address
he will now be thrown off after the password is
given with a "Bad Password" message.
This makes it a little harder for the hackers
to determine how they should proceed :-)
BUGFIX The Pattern mathing function failed when
the pattern was set to *.zip and the path
contained a . character.
This bug could affect the Upload Verification
module, the Banned File and the Dupe Checker.
Fixed
BUGFIX Sessions that "hangs" after a user has lost
his connection while up or downloading are
was not timing out.
Fixed.
BUGFIX The "mysterious" N4 (and Nt 3.51) bug where
the server crashed on some system when the
DIR command was given in the root directory
is found and fixed.
----------------------------------------
V. 1.28x experimental BETA July 24. 1996
----------------------------------------
CHANGE I did a little testing on NT with different thread
priorities to optimize performance when several
large directory listings were built.
The best overall performance was achieved by
lowering the priority of the threads that build
the directory listings whenever they kept the
shared data segments of VfSys unlocked. I
raised the priority whenever they accessed shared
memory to avoid situations where the main
thread would block, waiting for write access
to VfSys and one ore more lower priority threads
kept a read lock on it but was blocked by NT,
waiting for higher priority processes to
complete their work.
So the new design is:
Main thread
|
| Request data and continue with other users
|
v
Ls thread
|
Lower proirity and initialize
|
+-> Raise priority
loop Get VfSys Data for one directory
+-< Lower priority
|
Make a nice looking directory listing
|
Send a notification to the main thread about the
completion of the request
|
Raise priority
Loop back to start and wait for new requests.
This gave an acceptable performance with NT on a
single CPU system, and will probarbly boost
performance on a multiprocessor system.
Windows95 did not like to change the
priority all the time. I guess that the kernel
code for this is *very* inefficient, involving
physical memory transfers and relinking of the
threads protected memory data, and several
context switches. The performance fell by
~1000% on my worst case test.
This might be fixed in future versions of Win95, so
I have added options to set the number of ls threads
and "Optimal", "Mixed" and "Fixed" priority. This
option is located in the File System Options tab.
Mixed - NT Mode where the priority is changed
Fixed - The priority remains the same as the
main therad.
Optimal - A qualified guess made by the server
on what to do - based on the actual
operating system and version.
The number of ls therads are the maximum number the
server will use. When it start up it initialize one
thread. When a user issues a LIST command the server
checks if there are idle ls threads. If one (ore more)
threads are idle, it gets the request.
If no threads are idle (all are processing LIST commands)
the server checks if it can initiate a new therad and
does so if the number of ls threads are less than the
defined maximun.
If the maxuimun number of ls threads are running, it
checks how many pending requests there are on each
thread, and if they perform a simple or recursive
directory listing. It then queues the request to the
thread that most likely will finish it's current tasks
first and continue processing on other users.
(The "hold" state of the user in the user list can
mean that the user has a pendinng reuest on a ls
thread).
In the current version I have set the system defined
maximum to 30 threads. The server can handle up
to about 60 threads with the current design, but too
many threads will add a significant overhead both in
NT and in the servers locking functions for shared
memory.
There is also a bug in the Microsoft SDK that leads
to a small memory leak if more than 8 therads places
a read lock on a shared data segment, and one therad
waits for write access. (WaitForMultipleObjects).
The number of LS threads should therefore be 5 or
less.
CHANGE I had reported that the server "froze" under
Win95 when large partitions were loaded
into VfSys and VfSys was shut down.
The problem turned out to be a bug in Win95
when allocating large number of memory buffers.
Windows 95 simply ran out of system resources
and was unable to release the buffers. In stead
it froze the server, and then other programs
as well.
I performed a benchmark with ~26,000 files and
verified the problem.
I rescheduled the memory optimizing of VfSys
and implemented my own memory allocation
functions. As a result large partitions works
fine with Win95 and memory usage is reduced by 67%.
Under NT the operating system used 10,400 KB
to store the 26,000 file names and the global
data segments for the server.
With my memory functions this was reduced to
3,432 Kb.
It also gave a nice side effect of even faster
loading of the VfSys:
Load VfSys in version 1.26x 95940 ms (95.9 sec)
Load VfSys in version 1.27x 45135 ms (45.1 sec)
Load VfSys in version 1.28x 24015 ms (24.0 sec)
----------------------------------------
V. 1.27x experimental BETA July 23. 1996
----------------------------------------
ADDED Support in VfSys to handle comments and UNIX
attributes on read only directories and drives
(CD-ROM).
CHANGE VfSys can now be used when War is running as a
NT Service. The shutdown function has support
for fast shutdown and will in most cases
complete the shutdown process in a few seconds.
(Normal shutdown is a little slower as it will
release all used memory and other resources.)
CHANGE Optimized the Virtual file system. Reduced load
time by ~50% and decreased flushing time from
several minutes (worst case) to ~ 10 - 100 ms.
The following benchmark is performed on a Intel
Pentium 120 MHz based standard clone PC with
2 x Quantum Fireball IDE 1.3 GB drives and 48 MB
RAM running NT 4.0 Server.
(25968 files in 1107 directories loaded)
Load VfSys in version 1.26x 95940 ms (95.9 sec)
Load VfSys in version 1.27x 45135 ms (45.1 sec)
Also reduced memory usage and memory fragmentation
when running VfSys.
----------------------------------------
V. 1.26x experimental BETA July 21. 1996
----------------------------------------
ADDED NT Service support.
The server can now run as a native Windows Nt service.
This feature is still at an early stage. I just wanted
to know if this service implementation is so hard to
do as people claim. It is not. The current
implementation was done in just a few hours :-)
In order to run it as a server, follow these steps:
1) Log in to NT as *Administartor*.
2) Start the server as usual.
3) Open the Options/NT tab.
4) Select startup mode and (optionally)
an user account.
5) Press the [Update] button.
6) Exit War.
War will now be configured as a service. You can
start it from the Service Manager. It support the
following Service Manager commands:
Start - Starts up
Stop - Logs all users off and terminates
Pause - Goes offline
Continue - Goes online
Limitations/bugs:
There is no way to access or configure the server when it
is running as a service.
DO NOT USE VFSYS WHILE RUNNING IN SERVICE MODE. VFSYS
USES TOO LONG TIME TO FLUSH THE BUFFERS WHEN THE MACHINE
SHUTS DOWN. You can use VfSys if you manually stop the
server before shutting down the machine.
No control panel applet is available at the moment.
The Event Log messages make no sense at the moment.
However, both the regular log and the WU-FTPD log are
all right.
Notes:
When War is installed as a service it will try to start
as a service also when started as a normal application.
This gives a delay of ~30 seconds from you start War
until it shows up.
In order to confugure War when it is running as a service,
go to the Service Manager in the control panel and stop
"WAR-FTPD". Then you can start the server as usual and
do the configurations. When you are done, terminate War
and start it again as a service from the Service Manager.
ADDED Telnet command recognition in the FTP command parser.
This option is added to handle FTP clients that prefix
the ABOR command with Telnet codes.
BUGFIX When running vfsys the Free Diskspace option always reported
"Low on free diskspace".
Fixed.
----------------------------------------
V. 1.25x experimental BETA July 20. 1996
----------------------------------------
BUGFIX Minor bugfix in the modified pattern matching
module.
----------------------------------------
V. 1.24x experimental BETA July 20. 1996
----------------------------------------
ADDED UNIX WU-FTPD compatible log file in addition
to the current War log file.
There should be tons of scripts available
to process this new log file and make all
kind of fancy reports :-)
ADDED [$diskfree] macro. Reports free KB on the
(users) current drive.
ADDED test for free diskspace before accepting
upload. The requiered free space can be set in
the File System options tab.
ADDED Copy option to the Upload Verification
dialog.
CHANGE Modified the Path report to mark *all* inactive
paths as inactive, not just the paths unresolved
by VfSys.
CHANGE Modified the path parser to support non-mapped
paths if a parent path is mapped.
C:\ +root +home +map
D:\ftp +map
D:\ftp\incoming
The incoming directory will now be recognized
as /ftp/incoming and the attributes will apply.
In previous versions, each path that was defined
ouside the root path had to be mapped to root.
Note: If you want to give access to a path
outside the users root path, the lowest level path
still *has* to be mapped.
War woun't allow any absolute paths ouside the root
path.
CHANGE The entire source code (all 26.735 lines)
was reviewed and partially modified to
handle a MSVC++ 4.1 code generation
error that can cause GPF's.
CHANGE The log dialog is moved to the Options tab.
The dialog is also modified.
CHANGE Change in LIST parameter processing.
The LIST command will now always use
long listing format, also if the user
specify -1 or -C on the command line.
This is not logical, but comforms with
the behavior on UNIX servers.
Use the NLST (ls) command if you want
to use short or multicoloumn format.
BUGFIX When only 1 session was allowed on a user
account, pr. IP, the user was denied login
even if he was not previously logged on.
Fixed.
BUGFIX The server was a little paranoid with the
X:\ root directory. If a drive root was
the root path for a user, the user was
denied access to any subdirectory.
This bug was introduced with the 1.03x
version.
Fixed.
BUGFIX In version 1.23x a new bug was introduced:
Mapped dirs was displayed several times.
Fixed.
BUGFIX A dead lock situation was detected when
manualy restarting VfSys while there was
users online, and they performed directory
listings.
Fixed.
BUGFIX The console sometimes claimed to be "offline"
just after the server was started, and
it actually was "online".
Fixed.
----------------------------------------
V. 1.23x experimental BETA July 18. 1996
----------------------------------------
ADDED More threads on slow IO. Up to 6 threads can now work
together to speed up slow IO access upon directory listings,
in addition to the two primary processing threads (that
never perform any slow IO operations, except when they
flush VfSys or the user database).
CHANGE Internal design change in the locking scheme for multithread
access to shared memory. The new scheme taks a little more
CPU usage, but make the server run significatly faster when
there are many users online.
BUGFIX A dead lock situation was detected. The server could go into
a "dead lock" when two threads incrementally placed
a lock on the same objects.
Fixed.
----------------------------------------
V. 1.22x experimental BETA July 16. 1996
----------------------------------------
ADDED Upload verification processing script option.
The server can now start external programs to
perform CRC checks (or other validiation) on
incoming files prior to accepting the file.
It can also extract file_id.diz or perform other
processing on the incoming file.
BUGFIX A minor bug in the low level read function that
reads the fields in the user database was detected
and fixed.
----------------------------------------
V. 1.21x experimental BETA July 13. 1996
----------------------------------------
ADDED Import of Serv-U database.
----------------------------------------
V. 1.20b BETA July 11. 1996
----------------------------------------
ADDED Contents file to the online help.
BUGFIX The dupe checker was a little paranoid
and refused files that was defined in
the dupe exception list without a
leading *.
Fixed.
----------------------------------------
V. 1.04x experimental BETA July 10. 1996
----------------------------------------
ADDED Installation program with the distribution
BUGFIX REST (resume command) did not always reset
the start offset to 0 after the transfere,
or when the FTP client did not initiate a
transfer immediately.
This bug caused incompatibility with Cute FTP
version 1.5.
Fixed.
BUGFIX An error recovery function in the file send
module caused the server to crash.
Fixed.
----------------------------------------
V. 1.03x experimental BETA July 9. 1996
----------------------------------------
ADDED Disable banner checkbox in the welcome dialog.
CHANGE The format of the physical .Index.txt file has
changed. See the online documentation for
details.
BUGFIX Netscape failed to download files from the root
path when the Virtual File System was running,
and the physical directory not was assigned to
a logical name.
Fixed.
BUGFIX The [$credit] macro did always show the KB
ratio relation, also when the Up/Download
mode ws set to files.
Fixed.
BUGFIX If user or class was changed from the View Virtual
File System dialog, the new data was not always
saved.
Fixed.
BUGFIX When running the Virtual File System, directories
was not physically deleted when a user sent a
DELE command.
Fixed.
BUGFIX If the Virtual File System was restarted while
a user was uploading a file, the file would appear
twice in the directory listing sent to the
user.
Fixed.
BUGFIX A minor security problem was reported.
Fixed.
BUGFIX It was not possible to edit an alias name in
the FILE ACCESS TAB if the original directory
name was only one character long.
Fixed.
Note: Alias names *must* be 2 or more charactres
long. If a name is invalid, the server will
change it to a valid name.
BUGFIX The server would crash if a pathnames was
too long.
Fixed.
BUGFIX Multi-segment lines made the server strip
off command parameters.
Fixed.
----------------------------------------
V. 1.02x experimental BETA July 7. 1996
----------------------------------------
BUGFIX When running the virtual file system, deleted
files would not always be physical erased
from the disk, althoug they appered to be
deleted in the servers directory listings.
Fixed.
BUGFIX When the virtual file system was running,
it was not possible to upload files to
the first directory level in the root path.
Fixed.
BUGFIX CD .. would in some situations give
"Permission denied" when issued from a
mapped directory.
Fixed.
----------------------------------------
V. 1.01x experimental BETA June 28. 1996
----------------------------------------
ADDED Dupe exceptions in the Banned Files tab.
ADDED Account session time limit
ADDED Max simultaneous logins for an account based on
the callers IP number. You can now allow 30
anonymous users, but only 1 or 2 sessions for
each physical user.
ADDED Options/File System Options
Links are now shown as files by default (ls -L). This
option can be turned off.
CHANGE The system options on the main console will no longer
be hidden if the console is resized.
BUGFIX When VfSys was running and the root directory was
somewhere down the path, and mapped, the command
CD /SOMEDIR could fail.
Fixed.
------------------------------
V. 1.0b BETA June 23. 1996
------------------------------
ADDED Help.
BUGFIX WEB browsers had problems listing directories
on sites that diod not use the Virtual File
System.
Fixed.
------------------------------
V. 0.19a ALPHA June 21. 1996
------------------------------
I have now fixed all reported bugs that I have been able
to reproduce. Please report any problems.
CHANGE The "User and paths" report hide any path
deactivated by VfSys. They will now show
up as "INACTIVE". Also, the 'R' and 'H'
flags will now show the users real
Root and Home paths (and not all the paths
that had the Home or Root flag set).
BUGFIX FTP clients that split the command messages
into several TCP packages could both confuse and
make the server crash.
Assumed fixed (I can't test it).
BUGFIX The FTP command parser used a 256 byte buffer.
The recommended size is "at least" 4 KB.
Buffer size increased to 8 KB.
(And to the hackers...: Sorry, you can't
overload that buffer :-)
BUGFIX The OLE support for .lnk shortcuts (if not
using VfSys) was broken when the server went
multithreading (0.14a).
Fixed.
BUGFIX If you had VfSys running, created a new user,
and then added some paths for the user, the
paths would simply disappear the next time
the server was started.
The problem was that a flag that tells the
save() function to convert from VfSys paths
to DOS paths was not set correctly. The
paths was saved as VfSys paths and therefore
invalid. If you have seen this problem
do the following:
1) Take the server off-line
2) Stop VfSys
3) Go trough the users and delete
any non-DOS path (except "\").
The problem is now fixed.
BUGFIX When running without VfSys, and a X:\ style
path was root, mapped directories would
not show up in the directory listing.
Fixed.
BUGFIX When running without VfSys, and the root dir
was not mapped, CD / would fail.
Fixed. (It now maps to the root path).
BUGFIX When using Netscape Navigator, you sometimes
had to re-load the page to see the directory-
listing.
Fixed.
BUGFIX Sometimes mapped directories would show up in the
directory listings as *files*, not directories.
Fixed.
------------------------------
V. 0.18a ALPHA June 17. 1996
------------------------------
ADDED SITE: WHO SHUTDOWN ENABLE DISABLE MSGU OPEN
CLOSE ANON KICK
Also: "HELP SITE"
ADDED Security tab for Site commands completed.
ADDED Sound support on some events. You can visit
http://www.sky.net/~jdeshon/joewav.html for a
large number of cool sounds to use.
BUGFIX The multithreading support in the Virtual File System
sometimes caused the old cache to remain allocated when
it was restarted. (Problems with the Lock counters).
This could lead to a huge waste of memory and also
loss of information (uploader, download count etc.)
Fixed.
BUGFIX NT did not always flush the VfSys .Index.txt files,
causing information (uploader, download count etc.)
to be lost.
Fixed
BUGFIX If a user issued a SITE command when the spy
windows was active, the server could crash.
Fixed
BUGFIX Sometimes the server would crash when spying on users
while they logged on.
Fixed
------------------------------
V. 0.17a ALPHA June 16. 1996
------------------------------
ADDED Tool-tip for the toolbar.
ADDED Clear log-window command.
ADDED System Priority to the Options tab.
ADDED Feature to prevent the server from starting several
instances of the program from the same directory.
CHANGE In the current design of the File Access tab
there are some ambigous situations.
If the \ path is defined as roor + home, all
users will have access to all files, also
unprivileged users with another root path.
I have now denied access to un-mapped
paths before the users root-level, if the
root path has the mapping flag set.
In other words: If you have given a default
path of \ + root, and anonymoys \ftp\files + root
+ map, the anonymous user will not get access to
anything above \ftp\files, unless the paths are
mapped. If they are mapped, they will show up
as links in the users root directory
(\ftp\files\path)
BUGFIX Removed some minor memory leaks. (< 1 KB total)
BUGFIX Corrected the header name for sysmsg6.txt in the
View Messages tab.
BUGFIX DOS paths like C:\ + map did not show up in the
listings in the users root-dir.
Fixed.
BUGFIX The rename function in the server would move files
to the servers home directory, rather than renaming
the files when running without the VfSys.
Fixed.
BUGFIX Removed a ':' after 'total' in the LIST output to
make Netscape Navigator even more happy.
------------------------------
V. 0.16a ALPHA June 11. 1996
------------------------------
ADDED Validiation of "email as password". The server
does a basic check to ensure that the password
has a email-like syntax (something@).
WWWuser@ will be accepted.
BUGFIX There was a bug in VfSys's links when the links
was to directories. CD worked all right, but
the list command would sometimes show partially
listings of the parent dir.
Fixed.
BUGFIX Deletion of directories did not work.
Fixed.
BUGFIX If VfSys was not running and you had "\" as root path,
the intetranl path repersentation would be wrong on
mapped paths, causing all files to be unavailable for
access.
Fixed.
BUGFIX Fiexd a problem with the drive paths showing up as
/c /d etc. if "\" was root dir and VfSys was not running.
TEST I got a report that there is a 45 sec. delay from
the password is given to the user get logged in when
the server is running under NT 3.51.
I am not able to reproduse this delay.
------------------------------
V. 0.15a ALPHA June 10. 1996
------------------------------
Note: I finally changed the name. The name of the server is
war-ftpd. From now on the .zip file will contain the version
number.
Note: The setup information is moved from tFTPd32.ini to
FtpDaemon.ini, and many of the option names has changed.
When you install the new version, you must go into the
Properties/Options tab and configure the system.
ADDED Minimize option at startup
ADDED Password protection of the servers main window.
If you enable this option, you must have a
login account (FTP user) that belong in the
Sysadmin class, and you better remember his
password :-)
If you fail to get the main window back, shut
down the server from the tray-icon menu and
set the "Protected" value in FtpDaemon.ini
to 0.
ADDED Option to disable recursive directory listings
ADDED Option to disable output of the download counter
on the files in a directory.
(The download count shows up in the .Index.txt
files and if the user calls LIST -I)
CHANGE Moved most of the setup dialogs to a new tab.
BUGFIX Removed a possible cause of access violation.
BUGFIX Some minor bugs are fixed.
------------------------------
V. 0.14.1a ALPHA June 9. 1996
------------------------------
ADDED Multicolumn "-C" option to LIST
ADDED DOS path to the SPY dialog when running VfSys.
ADDED MDTM command. Reports the filedate in ascii. This is
used by some FTP clients and WEB browsers.
ADDED TYPE L 8 command is now recognized. Used by some
MAC FTP clients.
CHANGE Added better precision on the KB/Sec upload/
download info.
BUGFIX The Dupe Checker did not work.
Fixed
BUGFIX VfSys was not able to follow it's own paths when
a directory was a link.
Fixed
BUGFIX If the VfSys path was "C:\;d:\" (in stead of
"C:\,c-drive;D:\,files") users
would be refused on login with the message
"Access denied to homedir".
Fixed
BUGFIX The VfSys would flush each second in stead of
each 7. minute.
Fixed
BUGFIX If the users root dir was \ and it was mapped,
the paths reported by PWD would be wrong.
Fixed.
BUGFIX Fixed problem with long response messages
that were broken up without sending a '-' after
the response number.
BUGFIX Removed empty lines in response messages.
BUGFIX Removed a trailing 0 in the LIST output. This
zero caused big problems with ncftp.
------------------------------
V. 0.14.a ALPHA June 5. 1996
------------------------------
The big news this time is the new Virtual File System.
Please note that the .Index.txt file format has changed and
that the server no longer will understand the old format.
(This does not affect the user database and the information
stored there).
Please read the page describing the Virtual File System in the
supplied documentation file (tFTPd32.rtf).
I expect this release to be buggy and unreliable. Please report
any problems. New versions will be available rapidly in the next
two weeks. But I need to get the problems reported before I can
fix them :-)
Note: The UNIX ln command was announced for this verion. There
were some problems, so the command will have to wait a bit.
ADDED Multithreading.
ADDED Full pattern matching and recognition of most UNIX
ls line parameters on the LIST command.
Note: Multi-coloum output and sorting are still not
ready.
Mget should now work 100%.
ADDED Site commands for simplified implementations of the
following UNIX commands: chmod, chgrp, chown
ADDED Free Download of selected files (require the Virtual
File System to be running).
Note: Statistics are not counted for free files.
ADDED Dupe checker. The dupe checker will only work when the
virtual file system is running.
(The dupe checker will deny upload of filenames that
are known by the virtual file system if the "deny" option
is enabled in the Properties/Security/Banned Files tab.)
ADDED Popup-menu when right clicking on the tray icon.
CHANGE The log will now only be opened when there are data to
be written.
CHANGE The logfile is now only opened when there is something
to write to the log.
CHANGE When the user database is saved the server now writes to
a temporary file. When the file is successfully written
the old database file is saved with the name
"FtpDaemon.dat.bak".
CHANGE The server no longer gives any message if the user
IP is denied by absolute denial in the default setup.
Cute-ftp will "hang" until it time out. Ws_ftp will
detect that the connection is closed and report
"connection failed". I have not tested with other
FTP clients. however, this is the way most FTP servers
handle denied IP addresses.
CHANGE The tooltip text on the tray icon will now show the
port the server is listening to, to ease use of
multiple servers.
CHANGE Cosmetic change when selecting users in the user list
on the main console. You can now select a user by
clicing on any coloumn, and the entire row will be
colored. Also added sorting of any coloumn by clicking
at the coloumn header.
CHANGE The Rename functions will now also rename directories
CHANGE Resized the toolbar buttons to standard Windows apps.
size.
BUGFIX Upon receiving, the server would generate a number
of wasted internal notification messages.
Fixed.
BUGFIX Changing a file to a new name, and then back to the
original name would fail due to a bug in one of the
standard libraries.
Fixed.
BUGFIX The .lnk files would use the DOS 8.3 name conversion
for the destrination file.
Fixed.
------------------------------
V. 0.13a ALPHA April 6. 1996
------------------------------
UTILITY Due to some instability in the 0.12a version, I
have included the "chksvr" utility in the standard
distribution. See chksvr.txt for details.
CHANGE [$ulcount] and [$dlcount] will now show files or bytes,
depending on the users current U/D restriction type.
(There will be added new macros for explicit file and
byte information)
CHANGE Changed byte counters to be Kbytes counters to allow
larger totals. The largest number the counters can
keep now are 2,147,483,647 Kbytes.
Please verify that the conversion from bytes to Kbytes
are done ~right... (Keep a copy of your old database
file in case there are bugs - I'll fix this right away).
CHANGE Corrected spelling in [$programname] macro
CHANGE Resized the width of the main window to fit
within 640 x 480 (VGA) resolution. Now all
the options are displayed, also on low-res
monitors.
CHANGE When the Absolute option is used on the default
IP access list, the system will no longer scan
the default IP access list when verifying if a
user is denied access. This because he not would
have made it to the login prompt if he was denied
in the default IP access list.
Else, If you denied everyone, and let some masks
get trough in the default setup, all users within
the allowed masks would get access, no matter what
was specified on the user/group/class level.
(The access first scans all the lists for denial,
and if the user is denied, all lists for an
exception.)
CHANGE Added logic to not update the users counters
(Upload, Download, Logins etc.) unless these
fields actually had been edited, when the user
properties was updated.
The side effect of updating it all was that users
who were online could get their counters reset to
the values present prior to the change, even when
the changes were made in the file properties or
IP access list.
BUGFIX Sometimes the client area of the list-boxes in the
User maintenance/Security dialogs was grayed out.
I tracked this down to a bug/feature in Windows
and instructed windows to leave the areas alone :-)
Assumed fixed.
BUGFIX Sometimes the server would report en error on
successfully uploaded files. I believe this bug
was caused by a change in the Winsock design in
NT 4.0.
Assumed fixed.
BUGFIX When deleting users, the server would crash in
some situations (due to an uninitialized pointer).
Fixed.
BUGFIX PASV would use 127.0.0.1 as the IP address
to the server, instead of the actual IP
address. The result was that Netscape
Navigator/MS Internet Explorer failed to
get files.
Fixed. It will now use the IP address the
user logged in to, thus hiding other IP
addresses from users logging in to a virtual
multihoming server.
------------------------------
V. 0.12a ALPHA April 30. 1996
------------------------------
Note: I still have some bugs to work on, but release
this version now to help the sites that have
had problems with the library bug.
A new release with more bugfixes will follow
in a day or two...
ADDED: Absolute option in Default IP deny list.
IP's on the default list will be disconnected
at once if this option is set. This makes the
server behave like all other FTP servers with
IP access lists.
The other IP deny/access lists will behave like
before. (The server checks the IP number against
the user/group/class *and* default list after
the user has given his name.)
There has been many requests for this dual
functionality so I moved it up on my todo-list :-)
ADDED: SITE ICON command. Will force the server to add a
new system try icon. Added to re-enable contact
with the system console after Explorer crash in
NT 4.0.
This command is only available for users in the
"Sysadmin" class.
TEST: A problem was reported when deleting groups. I have
not been able to reproduce this.
BUGFIX: A bug in the Microsoft socket library was verified
and a workaround made. The system should now be
rock solid on high-impact systems, also under
Win95.
------------------------------
V. 0.11a ALPHA April 26. 1996
------------------------------
ADDED: Multihosting feature. See "Multih.txt" for details.
CHANGE: Some cosmetic improvements.
CHANGE: Changed the user list from ListBox to ListCtrl/report
mode. This was not the trivial task I had thought!
Thanks to Microsoft's poor documentation, I spent
7 hours before this list started to work.
Note: When the listCtrl looses focus, the selected
user is no longer highlighted. I have no idea of
how to work around this. To make it a little
easier to maintain the users online, I have added
a pop-up menu that pops up if you click on a
user # with the right mouse button.
CHANGE: Moved system message from Notepad to tabbed dialog.
BUGFIX: When using space + '.' in the paths the user could
sometimes get around some of the security checking.
Fixed.
BUGFIX: When pressing the [EDIT] button in the main window, the
server would crash.
Fixed.
------------------------------
V. 0.10a ALPHA April 25. 1996
------------------------------
ADDED: sysmsg9: Shows status info after up/download.
ADDED: Dialog popping up after Killing a user, asking
if the user should be refused in the future.
ADDED: 4 new views of the security dialog.
TEST: There has been messages on Usenet about problems with
WinSock and large files. I tested transmission of
10MB+ files between a NT Server and my own Win95 PC,
running the FTP server on my own machine.
I experienced problems with the control channel.
Cute-FTP sometimes failed to receive the directory
listing after uploading the lage file. I made some
changes in the FTP engine in the server, without
resolving the problem. I was also able to reproduce
the problem with other FTP clients.
When I ran the same test under NT, there was no
problems at all. I suspect this error to
be in the Win95 Winsock .dll *or* in the C++
liberaries I use. If there are bugs in the libraries
I will probarbly have to write my own low-level
network lib...
ADDED: Toolbar
Note: I have not been able to get the tooltip feature
to work yet.
CHANGE: The user list will now show "idle", "Upload" and "Download".
CHANGE: The server now looks for a ".message.ftp.txt" in it's
startup directory if the file not can be found in the
usres current directory.
This gives the option of a standard directory change
message for all dirs that don't have their own message.
------------------------------
V. 0.9a ALPHA April 22. 1996
------------------------------
ADDED: Reverse DNS lookup. (Has not been able to test it.)
ADDED: User Up/Download statistics. (10 on top)
ADDED: Bug report form in the help menu. Please use this
when reporting bugs. It provides info that speeds
up the work of tracing the problems.
CHANGE: The user database is flushed to disk every 10 minutes.
TEST: I received a report that the password given when a user
is created did not work. I was able to reproduce the
problem, but when I started to trace it, the problem
went away. I have not been able to reproduce it
with 0.9a. Please keep an eye on this feature.
TEST: I received a report that the server would require 2
uploaded files when the Up/Download limits was set
to 1 : 2 *bytes*. I was not able to reproduce the
problem in version 0.9a
TEST: I got a report that the server would crash if scandisk
was started when it was running. I ran scandisk with
no problems with the file system idle.
BUGFIX: The "alias" name in the File Security tab was not always
updated after a change.
Fixed.
BUGFIX: In version 0.6a, when the design of the file system
changed, a new bug was introduced. It was not possible
to CD to a mapped dir if the root dir was a drive
i.e. C:\ The CD would only work if the home dir was
somewhere down in a sub-directory.
Another related problem was that when the system was using
DOS mode in dir listings/paths, it was not possible to
"CD \" and get to the root dir.
[The path parsing functions, supporting DOS/UNIX style
paths + OLE .lnk files + mappings are now among the most
advanced and complex parts of the server]
Fixed.
BUGFIX: When the spy dialog was closed with the [x] button, or
by pressing the [ESC] key, it was not possible to
spy on that user again.
Same behavior is reported when closing a minimized
soy window.
Fixed.
BUGFIX: Traced down a memory leak that would allocate 8 KB
memory for each connection, and never release the
memory. There can still be memory leaks, but all I
have found in the current version is an unidentified 25
bytes buffer that remains allocated from the server starts
till it is shut down.
ALPHA TESTERS: Please keep an eye on your system and
report if the system runs slower after a day or two
without stopping the server.
BUGFIX: The server did not handle write error's on incoming files
very well. It will now abort the file transfer.
Log files will not be written if disk errors occur.
The user database will be corrupted if the disk where
it remains gets full. It is not possible to update
the user database in this situation, and the situation
will not be discovered before the error occurs.
Therefore: Make sure to start the server from a disk
partition that will not run full. Let the users fill
up other partitions or drives.
------------------------------
V. 0.8a ALPHA April 17. 1996
------------------------------
UPDATE: The dll's are updated to MSVC 4.1. If you are experiencing
problems with your existing dll's, get the dll .zip file.
BUGFIX: If max simultaneous users was specified on a user/group/class,
the user could not log in at all.
Fixed.
BUGFIX: Passwords added when the user was created was not stored.
Fixed.
BUGFIX: If a user logged in right after he was created, but before
the internal tables were synchronized (happens when you press
the [OK] button in the security dialog), the system would
chrash.
Fixed.
------------------------------
V. 0.7a ALPHA April 16. 1996
------------------------------
ADDED: (Win95) Icon in system tray. If the window is minimized, ESC
pressed or the close [X] button pressed, the server will hide
itself and only be available by clicking on the icon in the
system tray. The only way to stop the server is to use the
menu and choose Exit.
ADDED: Option in file system setup to disable the .Index.txt
file.
BUGFIX: When the system was offline and vfsys enabled, it would
crash if the OK button in the file system options was
pressed.
Fixed.
------------------------------
V. 0.6a ALPHA April 14. 1996
------------------------------
ADDED: Temporary hook to support "mget *" command.
NOTE: Regular pattern matching is still not supported,
only "*" can be used (ie. not *.txt etc..).
ADDED: SITE MSG <message>
The message will show up on the main console.
ADDED: Menu bar on the main console.
CHANGE: Design change in user/group dialogs and internal design.
This includes a mass-implementation of new features.
NOTE: The file format has changed and the system can no longer
read or understand the database files of previous versions.
The .ini file is compatible with previous versions.
CHANGE: System database is now encrypted.
CHANGE: Virtual files (LIST, ".Index.txt") are now listed in the log
under the DEBUG flag (and will only show up if the logging if
DEBUG messages are enabled).
CHANGE: Filesize are added to the logs notification of successfull
transfer.
CHANGE: Main console is now resizable.
BUGFIX: All reported bugs are supposed to be fixed.
------------------------------
V. 0.5a ALPHA April 4. 1996
------------------------------
ADDED: Extended access control. Now a user can be denied/allowed access
on system wide, user class, user group and user level.
The access control module checks the access in this order:
1) Is the userclass anonymous, and anonymous access denied?
2) Is the userclass not root, and general access denied?
3) Is there user-level access permissions?
4) Is there group-level access permissions?
5) Is there userclass-level access permissions?
6) Is there permissions at all?
If there is defined access or not access, the processing stops and
the user is given access or denied. If the state is undetermined
(grayed check box), the next test is performed.
1 - 2 are defined with the checkbuttons on the system console
3 is a new button in the user dialog
4 is a new button in the group dialog
5 - 6 are new buttons in the system options dialog.
There is also a simple report available, listing the users and their
permissions.
NOTE: Anonymous users can now be denied access from the system options
dialog, and from the system console. If they are denied access from
the system options dialog, users with userclass anonymous can still
log in if they are given explicit access in the user or group
dialogs. But if the button on the main console is pressed, they
are denied access no matter what the user or group settings says.
ADDED: OLE support for Win95 .lnk files. The .lnk files will show up
as mapped directories.
NOTE1: The user must have permission to the directory in order
to access the link. But the directory does not need to be mapped to
the users homedir.
The .lnk support is intended to make it easier for the user to
navigate in the system, not to make an easy way to surpass
security.
NOTE2: I have successfully downloaded files that was linked with
this method. However, Cute-ftp and WS_FTP has a bug in their parsing
of the directory listings that make them treat any links as directories,
and (as far as I can see) has no direct method to download links that
points directly to files. To fix this problem I list links to regular
files as normal files, without the 'l' flag set.
When such files are downloaded the server reports the correct name, but
the FTP clients will use the filename.lnk name. The files will have to be
manually renamed by the user after download.
***The user will still need to have permissions to the directory where
the actual file is located.
CHANGE: Changed internal system time functions from GMT to local time zone.
CHANGE: Removed security restriction that denied creation of directories at the
root level. (MKD C:\NEWDIR)
CHANGE: The tab order of the system console and the Msg User dialog are changed.
CHANGE: Help is made the default button on the system console.
BUGFIX: The server would crash if a user logged in and the group he belonged to
not was found.
Fixed.
BUGFIX: The path parser will now detect (and skip) /./ in the path.
BUGFIX: The .message.ftp.txt files was not closed after use.
Fixed.
------------------------------
V. 0.4a ALPHA April 3. 1996
------------------------------
ADDED: Users IP address to spy dialog.
ADDED: Textfile to display as welcome message when changing directory.
The filename can be modified in the system setup dialog.
Default filename is ".message.ftp.txt"
The message file have support for macros
Tested with Cute-ftp, MS Internet Explorer and Netscape Navigator.
ADDED: Full support for mapping of dirs. to home. The path will now show
the path from the homedir if the user is in any path mapped to the
homedir. If i.e. D:\ is mapped to C:\FTP, you can say "CD /C/FTP/D/BIN"
and come to the D:\BIN directory. The server will report "/C/FTP/D/BIN"
as the current directory (or "/D/BIN") if home is mapped to root.
ADDED: PASV command implemented.
ADDED: UNIX style link output on "ls -l" on mapped dirs.
ADDED: "System type" option in system setup, UNIX or Real.
This applies to the SYST command. If "Real" is checked
the system will report the actual operating system
(WIN32 + WN95 or NT). If "UNIX" is checked, it will
report "UNIX Type: L8" (I have no idea about what L8 stands for,
but it appears that Netscape Navigator wont accept the "ls -l" LIST
format without this response).
ADDED: "SIZE path" nonstandard FTP command implemented.
ADDED: Support for BINARY LIST transfer. (If UNIX file system, only newline are
sent as end-of-line marker).
CHANGE: The scrolling of the log window is changed. If the first line is selected
the first line will always be displayed on top. If another line is selected
then that selection will remain active, and new messages will not be visible
before the window is scrolled up manually.
CHANGE: The program will now terminate at once when the EXIT button is pressed.
In previous versions the EXIT button set a flag that was polled once
a second (when the log window is updated). In some rare cases the timer
would not start, and the program would not respond to the EXIT
button at all. This is now fixed.
CHANGE: The output from the LIST command is now comforming 100% with UNIX
standard (as far as there *is* such a thing...).
CHK: I got a report that permissions on the home dir. did not applied for the homedir.
I am not able to reproduce the problem. (Unless if I change the map parameter
when the user is online. The server does not handle that. If this happens,
the user must issue a "CD /" command to reset the FTP client's and the
servers recognition of the current working directory.)
CHK: I got a report that uploaded files not was shown in the Spy xmit history
dialog. I am not able to reproduce the problem.
FIX: Goodbye message was not sent.
Fixed.
BUGFIX: When using WS_FTP the server would sometimes show a wrong ".Index.txt"
file. The "problem" was that WS_FTP are optimizing speed by caching directory
information. The server was optimizing speed by not reading the directory
info into memory before the user issued a LIST command. What happened was that
the server kept a cache of the last directory read, containing the information
used to build the ".Index.txt" file, but sometimes for the wrong dir.
The servers cache is now trashed when the user issues a CWD command. It will
reload the directory info if the user want the ".Index.txt" file, even if
no LIST command is given.
Note: The ".Index.txt" file is created in memory, based on the cached
directory information. The file length reported by LIST is just an estimate.
The server will *only* load the ".Index.txt" for the current directory.
If a path is given, it will try to open a real file named ".Index.txt".
BUGFIX: If a file with an attached comment were deleted, it would result
in a page protection fault.
Fixed.
BUGFIX: The server asked for password for users without password.
Fixed.
BUGFIX: If a user had a name that was not the same as any group, the program
would get a page protection fault.
Fixed.
BUGFIX: User-Group dialog: It was not possible to add a new path when it was
part of an already defined path i.e. Could not add "D:\" if "D:\tmp" was
defined.
Fixed.
BUGFIX: A rare condition in the optional dir. combo-box (invalid selection) would
lead to a page protection fault.
Fixed.
BUGFIX: Virtual File system: (LIST) Number of dirs was not updated when only
drives was shown (PWD=\ --> show dives in stead of dirs/files).
Fixed.
BUGFIX: Serious problem with "CD /path/dir./../anotherdir". The path-parser did not
recognize the "/../" sequence, leaving the "anotherdir" open for access
with no access control.
Fixed.
BUGFIX: Sometimes the path was still shown as "/c/"
Fixed.
BUGFIX: "CD .." did not work very well if the current directory was "C:\"
Fixed.
BUGFIX: The server would not work with MS Internet Explorer and Netscape Navigator.
Fixed.
BUGFIX: The logfiles was not flushed at shutdown.
Fixed.
BUGFIX: Trying to delete an un-empty directory caused a page protection fault.
Fixed.
BUGFIX: Creating an existent directory (MKD) caused a page protection fault.
Fixed
------------------------------
V. 0.3a ALPHA March 31. 1996
------------------------------
ADDED: Spy: History of file xmits for the current connection
ADDED: Spy: User-account and connection-only file counters
ADDED: Macros for number of users online, max users online,
number of anonymous users online and max anonumous
users online.
FIX: "Locate cursor in first text filed in input dialogs"
Fixed.
FIX: "Blank user name should not be allowed"
Blank user and groupnames, and user and group names with
white space are now denied.
FIX: Macroes that displays current up/download counter will now
show session counters for session only for users with
session only up/download class.
FIX: Deny access to directories with no permissions checked
If you want to deny access to a directory in the users
homepath (or one of the optional paths), you add the
directory you want to close as an optional path and
turn off all file/dir. permissions.
FIX: Small icon used MFC instead of tFTPd style icon.
Fixed.
FIX: Cute FTP and "resolve links" is not working.
The problem was that Cute-ftp sent a LIST -L
command, that is undocumented in the FTP specs.
I have added a hook to just ignore this parameter for now,
and it seems that Cute-ftp is quite happy with the
standard UNIX "ls -l" it gets back...
BUGFIX: recognize CD "d:" and CD "d:\" as the same thing
BUGFIX: Unix style /c/ as current dir. is nonstandard and ugly
fixed. Will now display /c
BUGFIX: Unix style CD /c/usr don't work
fixed.
------------------------------
V. 0.2a ALPHA March 30. 1996
------------------------------
BUGFIX: "MKDIR reports 501 permission denied"
This was not a bug, but rather a logical error.
RMDIR was probithed when the user did not have
access to subdir (Apply for subdirs checkbox).
The dialog will now disable the Rmdir and Mkdir
checkboxes when the Apply for subdirs checkbox
is unchecked.
BUGFIX: "Mapped drive did not show up in homedir"
Unable to reproduce this error. If it is a problem somewhere,
I guess it will be fixed when I complete the implementation
of mapped directories (scheduled to the next release).
BUGFIX: "NT, problem with zombie server"
Fixed.
BUGFIX: "Win95, problem with displayed IP number when the PC is off-line."
Fixed.
Added RFC 1123 4.1.3.1 support
FTP allows "experimental" commands, whose names begin with
"X". If these commands are subsequently adopted as
standards, there may still be existing implementations using
the "X" form. At present, this is true for the directory
commands:
RFC-959 "Experimental"
* MKD XMKD
* RMD XRMD
* PWD XPWD
* CDUP XCUP
* CWD XCWD
All FTP implementations SHOULD recognize both forms of these
commands, by simply equating them with extra entries in the
command lookup table.
------------------------------
V. 0.1a ALPHA March 29. 1996
------------------------------
Virtual file system is not fully implemented. It will start and run, but
the server will not use it for any user services. Only the "comment on file"
benefit of the virtual file system is supported.
