Subject: C-Kermit 6.1 Beta.02
This is to announce C-Kermit 6.1 Beta.02. I'm still not announcing it to
the general public, but this time it's to a wider list, which I've moved
out of the headers. For the benefit of those of you who have not seen the
earlier Alpha and Beta announcements, I enclose a VERY brief summary of the
new features of C-Kermit 6.1 at the end.
Let me know if you want to be removed from this mailing list (mailings will
continue to go out about once or twice a month until C-Kermit 6.1 is done).
KERBEROS
The big item in Beta.02 is Kerberos authentication AND encryption for UNIX.
It looks like the winner of that programming contest I announced a few weeks
ago is... me :-)á There is now a new CONNECT module for Kerberos builds,
ckucns.c (instead of ckucon.c), that uses select() rather than fork() as its
control mechanism (more about this in the UNIX section below), thus allowing
the Kerberos libraries to share variables, as they must.
So far, there is exactly one Kerberized target in the makefile. It is for
Linux with the Cygnus Kerberos libraries installed:
http://www.cygnus.com/techie/kerbnet/
The current code is compatible with Kerberos V only. It is described in
the kerberos.txt file.
If you are in the USA or Canada, and you want to try the Kerberos support, or
to adapt it to another platform, or adapt it to Kerberos IV, contact me, since
certain modules are needed that can't be put on the public ftp site due to
export restrictions.
USING EXTERNAL COMMUNICATION PROGRAMS
The other big item is a new PIPE command that lets C-Kermit use an external
communications program to make the connection and do the communications i/o.
So now you can have Kermit scripting and file transfer over all sorts of
connections where you couldn't have them before, for example:
. Use cu to make serial connections for which Kermit lacks permission
. Run Kermit through secure and/or SOCKSified Telnet clients
. Make rlogin connections without being root
Like Kerberos, this feature is available only in UNIX. It works only with
programs that use standard i/o. It is described in section 2.7 of the
ckermit2.upd file.
If you're interested in adapting this feature to non-UNIX platforms, or
adapting it to use some mechanism other than pipes (e.g. ptys in UNIX
so it might work with non-stdio programs), let me know.
GENERAL CHANGES SINCE BETA.01:
. Added: Server can now handle GET request for filenames containing spaces.
. Added: Certain error messages that were missing from INPUT and OUTPUT.
. Added: REMOTE SET FILE INCOMPLETE { DISCARD, KEEP }.
. Added: New variable \v(osrelease) (from uname).
. Fixed: REMOTE command redirection with short-form replies.
. Fixed: Binary-mode mode file reception with SET PARITY SPACE.
. Fixed: SET HOST switches for non-serial, non-TCP connection methods.
. Fixed: Repeat-count compression could be skipped under certain conditions.
. Fixed: Broken REMOTE SET BLOCK-CHECK, RECEIVE TIMEOUT, and FILE NAMES.
. Fixed: Broken MKDIR & RMDIR commands when used in a macro or command file.
. Fixed: Redirectors for remote commands that return short-form replies.
. Fixed: Inability to edit the SET MODEM command.
. Fixed: Inability to edit a multiline SET KEY command.
. Increased: Maximum number of macro definitions for BIGBUFOK builds.
UNIX-SPECIFIC CHANGES
. Added: New UNIX CONNECT module based on select() rather than fork().
. Added: Kerberos V authentication AND encryption for Linux.
. Added: PIPE command for using external communication programs.
. Added: uname info is obtained at runtime.
. Added: New variables \v(osname) and \v(osversion) from uname info.
. Added: uname info to top of debug log.
. Added: Designer banners for BSDI 2.x, 3.x.
. Fixed: \v(cpu) to show machine name from uname in preference to "unknown".
. Fixed: Hanging in Linux after using /dev/ttyS* device.
. Fixed: HP-UX lockfile handling to be compatible across all versions.
. Fixed: \v(xxx) variables for directory names to all end with "/".
. Fixed: \v(inidir) when initialization file not found.
. Fixed: Compilation on Sunsoft Interactive UNIX 4.1 (from Kenneth Cochran).
. Fixed: "send /recursive foo" ("foo" not wild) didn't work.
The new UNIX CONNECT module is not only for Kerberos, and does not need
Kerberos to work. It's better than the old one in every way -- it's
snappier, it runs completely in the main Kermit process (rather than in two
forks) so there are no pipes or signals, tons of gross and error-prone code
have been removed, etc -- but it is not necessarily portable to all UNIX
platforms because it uses select() and requires that select() work on all
file descriptors (serial ports, pipes, etc) and not just sockets. If you
want to try it out:
make clean
mv ckucon.c ckucon.save
mv ckucns.c ckucon.c
make xxx
and then try CONNECT sessions on (a) serial connections, (b) telnet or rlogin
connections, and (c) pipe connections, and let me know the results. If it
works on all three, you can change the makefile entry to refer to the "xermit"
target instead of the "wermit" target, as was done in the SunOS 4.1 entry
(sunos41), which I have tested heavily here.
Open UNIX issues:
. Linux uucp lockfiles (port name aliases, chasing symbolic links, etc).
. More lockfiles needed for HP-UX? (C-Kermit now behaves just like cu.)
. Still no C-Kermit 6.1 version for the BeBox (but we made some progress).
VMS-SPECIFIC CHANGES
. Added: Support for transfer of odd-record-length files (from Lucas Hart).
. Added: Error message upon failure to spawn a process (from Lucas Hart).
. Added: SET TCP commands that were missing for no good reason.
. Fixed: Incorrect results from various "is-a-directory" tests (Lucas Hart).
. Fixed: getsockname() compilation warning (Lucas Hart).
. Fixed: Inability to receive a file with any name segment > 39 chars.
. Fixed: Spurious "Interrupted" message when sending certain kinds of files.
. Improved: Handling of RMDIR command failures.
. Disabled: High-precision timers for VMS prior to 5.0 (William Bader).
. Disabled: Reverse DNS lookup on UCX (doesn't work here).
Open VMS issues:
. LABELED mode lacks relative pathname option; directory-tree transfers
don't work between two VMS systems because they go into LABELED mode
automatically.
. Confusion about SET TRANSFER MODE { AUTOMATIC, MANUAL } vs FILE TYPE IMAGE
(should AUTOMATIC unset IMAGE? Should IMAGE set MANUAL? ...)
. Need better error message for failure to receive a file in text mode that
has lines longer than 32K, or else a way to recover when this happens,
e.g. by breaking the long line.
. DECnet-aware CD command -- work in progress, should be available in Beta.03.
. Fractured fullscreen file transfer display during GET (can't reproduce).
. I don't have access to Alpha VMS 6.x any more, can't make binaries, sorry.
THE MACINTOSH VERSION
There is no Macintosh version. My Macintosh died. I bought a new one, but
it's a Power Mac and won't run MPW C 3.2, and nobody can figure out how to
build C-Kermit with "Code Warrior" -- all the header files are different,
etc, even in the "MPW compatibility mode". Conversion is evidently a massive
job. Volunteers?
WHERE TO FIND IT
