Developed by Advanced Software Concepts, FTPShare is a set of communications applications which allow a Macintosh to be used as a multi-session background FTP file server. It can be accessed by any computer with an FTP client application over a TCP/IP network.
FTPShare provides a user access scheme similar to the one available in Apple's File Sharing for System 7.0, and allows :
- Files to be transferred between a Macintosh and FTP Clients,
- Up to 20 clients to connect at the same time,
- An access profile to be given to each user,
- Guest users to connect to the file server,
- Support of Aliases
- and many other features…
As the File Sharing, FTPShare comprises four components :
- FTPShare Setup : an application to start, stop and configure the server,
- FTPShare Monitor : an application to monitor the server's activity,
- FTPShare Users : an application to define the users profiles,
- FTPShare Extension : an INIT to install in the System Folder.
FTPShare works in the background of the Macintosh leaving it free to be used as usual. It also provides a monitor which allows you to control who is connected to the file server and which folders are being accessed.
Although FTPShare supports some special System 7.0 features such as Aliases and Balloon Help, it can also be used on System 6.0.4 machines.
Enclosed is a demo version of FTPShare. This FTPShare version is fully functional, except that the server stops running after 15 minutes. Then, you have to restart your Macintosh to activate it again.
Hardware & Software Requirements :
---------------------------------
• Any Macintosh with at least 128K Roms (Macintosh Plus and newers).
• Macintosh System Software 6.0.4 or later.
• MacTCP v. 1.1 or later, the Apple TCP/IP driver for the Macintosh.
Installation Procedure for FTPShare :
----------------------------------
1) Make sure MacTCP is correctly installed.
In System 7.0, MacTCP must be stored in the Control Panel folder, and for
versions 1.0.x of MacTCP, an alias must be created and stored at the top
level of the System Folder.
2) Drag the FTPShare Extension into :
- the Extensions folder, located in the System Folder when running System 7.0.
- the System Folder when running System 6.0x.
3) Create a new folder on your hard disk, and give it a name such as "FTP Users".
This folder will be used to keep a record of all the users that are allowed to
connect to the file server.
4) Drag the FTPShare Users application into the new folder.
5) Drag the FTPShare Setup and the FTPShare Monitor applications into the same
folder. These applications can be kept elsewhere if preferred.
6) Restart your Macintosh.
7) Use the On-line help if you have any problems.
Defining Users :
--------------
This is the only part of the FTPShare package where a few explanations could be of some help…
• The FTP Users Folder
The users you define through the FTPShare Users application are stored as files,
and they must be kept in the same folder as the application if you want them to
be recognized by the FTP server. This FTP Users folder can be stored anywhere on
your hard disk. As for any other folder, you may set views by icons, small icons
or sorted by name.
• The Entry Folders
You must define for each user an "Entry Folder" which is the folder that the user
will first have access to when opening a session with the FTP server. A user has
access to all the files and folders included in its Entry Folder. You can also
define its access privilege to these items (Read-Only, Write-Only or
Read-and-Write).
An Entry Folder can contain files, folders or aliases. For example, if a user
asks to receive an alias file, it will not receive the alias but the original
file. Similarly, the "admin" user can send the Change Directory command
specifying the "Server" AppleShare volume alias: in which case the volume is
automatically mounted provided that the AppleShare File Server does not require a
password.
Important : For security reasons, if the alias of a folder is not directly
included in the Entry Folder, in the "FTP Users" Folder or in one of their
sub-directories, the user will not be allowed to enter in the original folder.
• The User Icon
When configuring a user profile, if you do not check "Allow user to connect" or
"Allow guest to connect", an X appears through the user's icon. Note also the
difference between a USser icon and a Guest Icon : a Guest Icon is partially
grayed out.
Special features :
----------------
• Allowing Users to Configure their Password by their own
If you enter ??? as password when configuring a user profile, the user will be
asked to configure the password when connecting to the server for the first time.
Once the new password is entered, it must be confirmed through the account (ACCT)
command.
• Owner's Privileges
The owner can launch an application on the server, or reboot the server. To
launch an application, send the command LNCH <application>. To reboot the server,
send the command BOOT. These commands can be useful to install an INIT or a
driver on the server.
• About Paths
Full paths can be used by the owner for every command (send, receive, rename,
delete, …) except the list commands (LIST and NLST). They can only be used by the
users in the Change Working Directory command (CWD).
• About Lists
Files lists are returned by the FTPShare server under a form similar to the one
used by Unix FTP servers, for example :
flags size date type name
vrwx 7179264 May 20 04:15 - HD-Internal/
vrwx 29707264 May 20 04:36 - Mail/
-rwm 10052 May 20 04:16 mac AppleShare PDS
-rw- 1580 Jun 8 1991 txt asc_States.c
-rw- 422 Mar 27 07:06 txt Clipboard 0
-rwx 5435 Feb 28 11:48 mac Configure CEToolbox
---m 106425 Jan 01 1991 mac Desktop
---m 73728 May 20 05:54 mac Desktop DB
---m 498048 May 20 04:45 mac Desktop DF
drwx 42 May 20 04:15 - Desktop Folder
lrwd - Mar 31 03:48 - controls -> Control Panels
-rw- 13133 Nov 26 1991 txt FTPack.log
lrwx - Nov 14 1991 mac HC 2 -> HyperCard 2.0
- Flags
The first letter can be v for a volume, d for a directory, l for an alias or -
for a file.
The second letter is r if the user has Read access to the item, - otherwise.
The third letter is w if the user has Write access to the item, - otherwise.
The fourth letter can be x for an application or a directory in which the user
can see files, - for a Text file or m for any other Macintosh file (which
should be received in MacBinary format). However, if the item is an alias, the
fourth letter displays the type of the original item : d for a volume or a
folder, x for an application, - for a Text file, or m for other Macintosh
files.
- Size
The size is displayed in bytes used for files or volumes, in number of included
files for directories. The size of an alias is not displayed because it would
take to long a time to retreive the size of the original item.
- Date
As in Unix systems, the date is displayed under the format "month/day year"
for items which have not been modified during the last six month, and under the
format "month/day hour:minute" otherwise.
- Type
This column displays the type of the item, and thus the file transfer mode
which should be used to read it. The type can be - for volumes or directories,
txt for Text files and mac for applications and all other files which should
be received using the MacBinary file transfer mode.
- Name
This column displays the name of the item. If it is an alias, the name is
followed by an arrow "->" and the name of the original item.
- Note to Power-Users: If you issue the "site MAC" command, the file list
displays the files signatures. Enter "site UNIX" to return to standard mode.
- Note to VM/CMS Users: If the FTP client on your host does not support filename
containing spaces, enter the "site VM" command just after login. FTP Share then
turns spaces into underscores '_' when listing a directory, and vice-versa when
you send a command followed by a filename (cd, get, put, ...). Enter "site
UNIX" or "site MAC" to return to the standard mode.
• About memory
FTPShare needs about 100k for the first session, and about 35k for each
additionnal session.
Note: For better performance, you should set a Cache Size of 128 or 256 Kb in
the Memory Control Panel.
