KERMIT 95 2.0/2.1 BUG LIST ADDITIONS AND UPDATES
Most recent update: Sun Nov 28 15:54:26 2010
--------------------------------------------------------------------------
Bugs, Workarounds, Hints and Tips discovered since K95 2.0 was released.
All software has bugs; we document ours as soon as we learn of them, and
offer workarounds when possible. Visit this page from time to time for
news or if you think you've discovered a bug; maybe it's already discussed
here. Send questions or bug reports to:
This file is a continuation of the chronological Kermit 95 bug list:
http://www.columbia.edu/kermit/k95bugs.html
Perhaps with some overlap (at this writing k95bugs.html ends at number 711).
The current shrinkwrapped version of Kermit 95 is 2.1.2; thus any bug
fixes listed here for K95 2.1.3 can be obtained by downloading
the 2.1.3 upgrade available from:
http://www.columbia.edu/kermit/k95upgrade.html
All bug fixes listed for 2.1.2 or earlier are already incorporated into
the shrinkwrapped version.
Bug fixes listed as being fixed for the next release are not yet available.
--------------------------------------------------------------------------
663. Spurious K95G screen clearing on startup
If you launch a K95G connection from the Dialer, and the Dialer entry changes
the terminal dimensions, and then if you move the K95G window (and only the
first time you move it), the Terminal screen is cleared (but not lost; the
cleared material is still available in the scrollback buffer). Seems to be
fixed in version 2.1.3.
664. Everson Mono Terminal Font Side Effects
It is conceivable that the presence of Everson Mono Terminal on your PC might
affect other applications, such as Netscape, that search for appropriate fonts
to display text in various scripts. In such cases, if the result is
undesirable, you might need to reconfigure the affected applications, or
uninstall Everson Mono Terminal (in the Windows Control-Panel Fonts dialog).
665. Dimensions popup inactive during resize
(Not a bug) If you disable screen updates while moving windows (e.g. in
Windows XP Desktop -> Properties -> Appearrance -> Show window
contents while dragging), then in K95G when Actions -> Resize Mode
-> Changes Dimensions is selected the popup that shows the changing
dimensions is not updated, and with Actions -> Resize Mode ->
Scales Font, you can't watch the font change size.
666. Possible Help -> Manual misbehavior
K95G and the Dialer have Help -> Manual dialogs, which bring up the Kermit
95 manual in your Web browser. This works fine for most users, but several
users have reported various failures or problems with interaction between K95
or the Dialer and browser; these have to do with the particular browser and
version, the particular OS and version, and K95's SET BROWSER value, if any.
K95G and the Dialer are using totally standard APIs for invoking the browser.
In a pinch you can refer to the manual directly using something like:
file:///C:/Program%20Files/Kermit%2095%202.0/docs/manual/kermit95.htm
667. Underline and Blink control
In K95G 2.0, SET TERMINAL ATTRIBUTES UNDERLINE OFF does not disable
underlining; SET TERMINAL ATTTRIBUTE BLINKING OFF does not disable blinking.
Fixed in 2.0.1. In K95 2.1.3 you can also create a nonblinking cursor with
SET TERMINAL CURSOR <i>style</i> NOBLINK.
668. Host-Initiated Resize vs Font Scaling
In K95G 2.0, when the Window is maximized and K95's Resize Mode is "Scales
Font", if the host changes the line width, the font did not resize properly.
Mostly fixed in 2.0.1. Should be completely fixed in 2.1.3.
669. SET GUI WINDOW RESIZE-MODE command missing
There was no SET GUI WINDOW RESIZE-MODE command in K95G 2.0 to match the
Actions -> Resize Mode menu item. Fixed in 2.0.1.
670. Trouble with COM ports
COM-port connections (but not TAPI ones) could become disconnected upon
escaping back to the Command screen and then re-entering the terminal screen.
Fixed in 2.0.1.
671. Toolbar always visible
K95G 2.0 has no method of disabling the functionality of the Tool bar or Menu
bar. Version 2.1 has a new command SET GUI TOOLBAR OFF, which disables parts
of the toolbar (but does not make it invisible). Similarly for MENUBAR.
Version 2.1.3 adds command-line options to remove the Menu and Tool bars.
672. Upgrade Registration Problem
Copying the registration info from your old K95 version to 2.0 could fail
if your old registration did not include a company name. Fixed in 2.0.1.
673. SRP authentication attempted when not configured on incoming connections
This is a bug that affects 1.1.21 through 2.0.1. It is fixed in version 2.1.
The way to avoid it is to specify a SET TELNET AUTH TYPE
command that does not include SRP. This command would be placed in
either the IKSD.KSC (for Internet Kermit Service) or K95CUSTOM.INI
or K95SITE.INI depending on how K95 is being used to accept incoming
connections.
674. Extended argument error
When starting K95G from a Dialer entry that was cloned from a template, K95G
can fail, reporting an "Extended argument error". Diagnosis: Templates have
Lucida Console hard-coded as the default font, but Lucida Console is not
necessarily installed on every Windows computer. To compound the problem,
K95G fails to start if given an invalid font in the --facename: command-line
option. Fixed in version 2.1. Workaround: Install Lucida Console; you
can download it from http://www.microsoft.com/truetype/fontpack/. And/or
change the font on the GUI page of the template (and any entries cloned from
it) to be a monospace font that you have, such as Courier New.
675. Non-English Directory Names
Windows directories such as C:\Documents and Settings\xxx\Application Data\
can have different names in different countries, e.g. in Germany:
C:\Dokumente und Einstellungen\xxx\Anwendungsdaten\Kermit 95\
For the most part, K95 handles these correctly, but different behavior
(or misbehavior) can occur on different Windows versions; for example,
the Dialer, on first use, might create:
C:\Dokumente und Einstellungen\xxx\Application Data\Kermit 95\
which confuses the definition of Kermit variables such as \v(appdata) and
\v(common), which in turn can interfere with proper location of K95's
initialization and customization files. Windows 2000 and XP should be OK;
Windows 9x/ME with IE 5.01 or later should be OK; others might have this
problem, which we will attempt to address in a future release.
676. SSH-AGENT.EXE Broken
Apparently this was never tested and nobody noticed until after K95 2.0
was released. The problems also involve K95's interface to SSH-AGENT.
Fixed in version 2.1.
677. Default RGB color values in Dialer off by one
The default RGB values on the Dialer's GUI page should use 128 instead of
127 as the binary value. Fixed in 2.1.
678. Bulk License update loses number of seats
After applying the K95 2.0 upgrade installation to a Bulk Right-to-Copy
license, the number of seats displayed in the registration screen goes from
whatever it was (e.g. 100) to 1. This was a bug in the original upgrade
installer. It is fixed as of 12 June 2002 16:30:00 Eastern USA time. If your
upgrade was affected by this bug: first make sure your old K95 version is
still on the disk (reinstall from CD if necessary), then use Add/Remove
Programs to remove "Kermit 95 2.0", then download a new copy of the upgrade
from http://www.columbia.edu/kermit/k95upgrade.html and apply it.
679. SSH connections refused
If you get "connection refused", it probably means you are attempting a
connection to a server that does not support compression, yet Kermit is
configured by default to require compression. Try SET SSH COMPRESSION
OFF or, equivalently, uncheck Data Compression on the Dialer entry's SSH
Settings page.
680. TLS CBC Cipher incompatibility with IBM Info Exchange
Between the release of Kermit 95 1.1.21 and Kermit 95 2.0 a vulnerability was
discovered in the SSL/TLS Cipher Suite being used by IBM. IBM is using 56-bit
DES in Cipher Block Check mode. This cipher is weak and because of a recent
discovery the CBC mode has been shown to data leakage. The contents of the
data stream can be read by a passive attacker. This vulnerability can be
avoided if the SSL/TLS implementation forces the transmission of an empty
SSL/TLS frame (one that contains no application data.)
Kermit 95 uses the OpenSSL open source library as our implementation
of SSL/TLS. Between 1.1.21 and 2.0 newer releases of OpenSSL became
available. The fix to avoid the vulnerability was incorporated into
Kermit 95 2.0 when we updated to the newer OpenSSL library.
As it turns out, the IBM server violates the SSL/TLS protocol
specification by failing to properly handle empty frames.
A workaround is to use a non-CBC mode cipher until IBM is able to
update their server:
SET AUTH TLS CIPHER-LIST EXP1024-RC4-SHA
681. SET TRANSFER MODE MANUAL doesn't completely work
To force a particular file-transfer mode (text or binary) globally for
all transfers, you are supposed to use SET TRANSFER MODE MANUAL to
disable automatic per-file text/binary mode switching and then choose the
disired mode with SET FILE TYPE (Kermit) or SET FTP TYPE (FTP). This is
not quite sufficient, however. To finish the job, also SET FILE SCAN OFF.
The bug is that SET TRANSFER MODE MANUAL is supposed to imply SET FILE
SCAN OFF. Fixed in version 2.1.
682. COPY command destination file can have junk at end
If the destination of a COPY command is an existing file and the source file
is shorter than the destination file, the source file overlays the
destination file without truncating the excess. Fixed in 2.1. Workaround:
delete the destination file first.
683. Secure FTP authorization failure error message missing
FTP authorization failures were not being reported to the user (even though
the FTP OPEN command failed properly). Fixed in version 2.1. Workaround: SET
FTP DEBUG ON to see the protocol-level messages.
684. Fencepost error in FTP MGET /UPDATE
In FTP MGET /UPDATE, equal times spuriously caused download. Fixed in 2.1.
685. In FTP MGET /RECOVER failures
In FTP MGET /RECOVER, recovery was skipped if the local file is newer than the
remote. This would seem to make sense, but when a download is interrupted,
the partial file never gets the date of the remote file, so the partial file
is always newer, and recovery never works. Of course this is also true when
the partial file was downloaded by any program that does not reproduce the
server's file date. Fixed in version 2.1 by ignoring file dates in recovery
operations, and also by setting the file date for a partially received file.
686. Redundant downloads in FTP MGET /RECOVER wildcard wildcard...
The first file in each wildcard group would always be downloaded. Fixed
in 2.1.
687. Missing message for FTP MGET /EXCEPT
When TRANSFER DISPLAY is set to BRIEF, files skipped due to exception-list
pattern match are reported as "ERROR" with no reason. The operation works,
but the message is misleading. Fixed in 2.1.
688. Automatic Locus switching fails when FTP connection drops
If an FTP transfer was in progress with automatic locus switching enabled
but the FTP connection drops, the locus does not change back; thus (for
example) a subsequent DELETE command makes Kermit send a REMOTE DELETE
packet on stdout rather than delete a local file. Fixed in 2.1.
689. FILE INCOMPLETE setting ignored by FTP module
The FTP module never handled SET FILE INCOMPLETE. Fixed in 2.1.
690. FTP MGET sends superfluous commands to server
When an FTP MGET command has selection clauses that would exclude a file
based on its name (e.g. /COLLISION:DISCARD, /EXCEPT:pattern), it sent
SIZE and/or MDTIM commands to the server for files that would have been
skipped even without this information, which could slow a multifile download
unnecessarily. Fixed in 2.1.
691. FTP MGET pattern1 pattern2 pattern3 could stop prematurely
If a list of patterns is given to FTP MGET and any of the patterns matched
no files, the download would stop at that point, rather than proceeding to
the next pattern. Fixed in 2.1.
692. Interrupting FTP operations with Ctrl-C is problematic
It's a hard problem. To be addressed in a future release.
693. Terminal screen might have fewer columns than desired
If you choose a font and size that would make the Kermit window wider than
the screen at the chosen number of columns, Kermit creates the window with
the maximum number of columns that fit across the screen; for example, 78
instead of 80. Workaround: choose a smaller font size. This should be much
improved in version 2.1, and totally fixed in 2.1.3.
694. /POPUP switches in GUI version work improperly
When a /POPUP switch is used in the GUI with commands such as ASK the
generated popup is missing the frame and is displayed with a random
color instead of the HELP color. Workaround: Use SET GUI DIALOGS OFF
or use the /GUI switch instead of /POPUP. Fixed in 2.1.
695. Changing GUI Resize-Mode behavior while maximized
If the resize-mode is altered while the window is maximized, the
condition of the window when restored is undesireable. Fixed in 2.1.3.
696. SET COMMAND CURSOR-POSITION
The SET COMMAND CURSOR-POSITION command does not work. Fixed in 2.1.
697. SSH disables password-based logins upon key change detection
When an SSH Key Change is detected, the password based logins are
disabled in order to prevent theft of user passwords. However, this
state is not restored for subsequent connection attempts and password
based logins cannot be performed until K95 is restarted. Fixed in 2.1.
698. Scroll-mode exiting not always possible using the GUI scrollbar
Workaround: use the End key. Fixed in 2.1.
699. FTP PUT text-mode character-set translation broken
Character-set translation during FTP PUT operations is broken in 2.0, with
no workaround. TEXT transfers without character set translation work fine.
Fixed in 2.1.
700. SET TERMINAL IDLE-TIMEOUT does not stick in some circumstances
The TELNET, SSH, and SET HOST /CONNECT operations when executed after a SET
TERMINAL IDLE-TIMEOUT command will configure kermit in a manner such that
after exiting CONNECT mode, the IDLE-TIMEOUT value would be reset. This does
not happen if SET HOST ... is followed by CONNECT instead of using one of the
combined commands. Fixed in 2.1.
701. Unable to write to various Windows directories from K95
This is not a bug. K95 checks the READ-ONLY attribute of Directory
entries. If a directory is marked read-only, it will not be writable.
The default attribute values for each user's
Application Data
Favorites
My Documents
Recent
SentTo
Start Menu
directories have the "Read-only" attribute set. This is set by the
Windows Shell to indicate that these directories are "special".
K95 2.1 has been modified to ignore the read-only flag when set on
directories.
702. Everson Mono Terminal font misbehavior on Win9x/ME
In earlier versions of Windows, the Everson Mono Terminal font might
look like chicken scratches and sometimes shows a strange horizontal
compression, to the extent that a regular 80-column x 24-row terminal
screen is taller than it is wide. It behaves (and looks) much better on
Windows 2000 and XP (it can also be used successfully on earlier Windows
versions that have such enhancements as Font Smoothing or Clear Type
installed). Even then, however, it has some drawbacks: the vertical
spacing is greater than most other monospace fonts, allowing fewer lines
per screen at a given size; the rendering is a bit light; and line- and
box-drawing characters tend not to line up right. It looks better in
certain color combinations, such as black on white. We hope that this font
will improve over time. Despite its drawbacks, we include it with K95 to
allow access to scripts and languages you would not otherwise be able to
see in a terminal session: Georgian, Armenian, Katakana, Cherokee, Coptic,
Runes, Ogham, etc, because these characters are not included in widely
available monospace fonts like Courier New and Lucida Console. If you
don't need these characters, you might prefer to use a different font.
Beginning in K95 2.1, the default Installer behavior is not to install it.
703. FTP MGET might fail immediately with invalid tempfile name
This bug was new to K95 2.1.0. Temporary filenames for FTP were being
constructed within a buffer that could be too small. Fixed in 2.1.1.
704. FTP MGET fails when directory segments contain wildcards
For example, "ftp mget */data/*.dat". New to 2.1.0; fixed in 2.1.1.
705. Kerberos Leash shows garbage for local domain
Leash32 Options -> Kerberos Properties -> Your Computer's Domain
shows random garbage; this is a known bug in MIT Leash32 2.2.0.
Fixed the version of Leash that is included with K95 2.1.2.
706. K95 can't download files named CON or CON.anything
This is a DOS and Windows feature. The same is true for any file whose
name (the part before the dot, if any) corresponds to a DOS device name
like CON, LPT, PRN, or COM1. It's not a Kermit problem. You can't create
a file on disk with such a name using any other Windows application either.
707. TELNET Com Port Control vs the INPUT command
Numerous problem with the TELNET CPC option and the INPUT command have been
resolved in K95 2.1.2. The INPUT command would improperly close the network
connection to the host if the Carrier Detect (CD) signal was not raised; even
if Kermit's CARRIER WATCH setting was OFF. The network connection should not
be closed simply because there is no carrier signal.
708. VTNT connections vs Ctrl-C
Reportedly the VTNT server absorbs Ctrl-C characters. Kermit 95 sends them,
but they have no effect at the remote session. If the report is true, this
would be a problem with the remote server, not with Kermit 95.
709. Mouse print selection broken in GUI
Button 1 Ctrl-Shift-Drag (default assignment) is supposed to select screen
text and send it to the printer. This doesn't work in K95 2.1; it either
prints the whole screen or nothing at all. Diagnosis: a race condition
between threads; The thread that is being spun off to perform the print job is
not starting before mark mode is terminated. Workaround: Select/Copy the
text, then paste into WordPad or something, then print it. An all-in-K95
workaround would be define a macro that writes the contents of the \v(select)
variable to a file, then prints the file, then deletes the file. The macro
could be assigned to a mouse event of your choice with the SET MOUSE
command. Fixed in 2.1.3.
710. K95 does not support remote SSH agent proxies
This feature is added in K95 2.1.3.
711. Maximize and Restore versus Resize Mode
(Not a bug) In the GUI version of K95, when the Resize Mode is Change
Dimensions and you maximize the window and then restore it, you get a blank
screen. Whenever a window's height is reduced, the entire contents of the
window are placed into the scrollback buffer to ensure that the data will not
be overwritten or become garbage. This behavior has never changed, but might
be more obvious now that the Maximize and Restore controls work.
712. FTP Brief-format transaction log shows wrong status
If a transfer failed, the log entry said OK; if the transfer succeeded the
entry said FAILED. Fixed in 2.1.3.
713. FTP connections always complain about 'FEAT' command
Kermit sends a FEAT command to see what features the server supports.
However, the FEAT command itself is a relatively new addition to FTP protocol,
so most servers don't understand it and and reply with an error message such
as "'FEAT': Command not understood", which Kermit displays. K95 2.1.3
suppresses this error message unless FTP DEBUG is ON.
714. Problems with FTP [M]GET /RECURSIVE
FTP GET /RECURSIVE somepath/somefile didn't work and
MGET /RECURSIVE */somedir/* downloaded the files into the current directory,
rather than re-creating the remote directory structure. Fixed in K95 2.1.3.
715. FTP USER and similar commands don't strip quotes
In most contexts there is no way to specify an FTP username that contains one
or more spaces. Normally this would be done by enclosing the name in
doublequotes or braces, but the parsing code in this did not strip the
enclosing quotes or braces before sending the username to the server. Ditto
for password and account. To be fixed in the next release. Workaround:
assign the multiword values to variables and use the variables. Example:
assign \%u Fred Foo
assign \%p Secret Password
ftp user \%u \%p
716. FTP MPUT requires all filespecs to match at least one file
The command "ftp mput *.jpg *.gif *.bmp" gets a parse error and does not
execute if any of the file specifications do not match any files. This is
fine for interactive sessions, but not good for scripts. For scripts
use something like:
ftp mput *.jpg
ftp mput *.gif
ftp mput *.tif
or:
ftp mput *.{jpg,gif,tif}
or:
ftp mput "{*.jpg,*.gif,*.tif}"
Type HELP WILDCARDS for more information about the syntax. Fixed in 2.1.3,
which allows FTP MPUT commands to contain filenames or patterns that do not
match any files, and the command will simply skip over them and still transfer
any files that do match, and will fail only if no files match at all, or if
any of the transfers fail.
717. GREP (FIND) does not allow pattern variables
The GREP (FIND, SEARCH) command does not expand pattern variables; it takes
the pattern literally. To be fixed in the next release. Workaround:
define mygrep {
local xx
assign xx {
find \%1 \%2
if fail end 1
}
do xx
if fail end 1
}
and then use MGREP instead of GREP.
718. Dialer GUI Menu/Tool/Status Bar settings don't stick
Any changes to the Menu Bar, Tool Bar, or Status Bar check boxes
in the Dialer's GUI Settings page are not saved when you exit from the
Dialer.
Workaround: After checking or unchecking the GUI-page boxes as desired,
click OK on the GUI page, then click Shortcut on the Dialer's Toolbar, then
launch the connection from the shortcut rather than from the Dialer entry.
This is fixed in the next release.
719. The K95 command parser does not handle the NUL device
Using NUL (or NUL: or NUL.anything) in a Kermit command in place of a
filename does not always the expected effect. Instead, the command tends
to fail with "?file not found".
This is fixed in the next release.
720. INPUT n \fpattern(xxx) doesn't work for case-independent matches
Fixed in the next release.
721. MINPUT n ... \fpattern(xxx) ... doesn't work at all.
The MINPUT command does not handle patterns. Fixed in the next release.
722. Associative array references not case sensitive
Fixed in the next release.
723. SET KEY xxx \27H erroneously lowercases the value
Any SET KEY command in which the first character of the definition was
backslash quantity, and the ONLY character after the backslash quantity
was an uppercase letter, e.g. "set key \1234 \27H", would erroneously
lowercase the letter. Fixed in the next release.
724. Failing FTP CD/CDUP/RMDIR does not set failure status
FTP CD, FTP CDUP, and FTP RMDIR did not set the failure status when they
failed, thus IF FAILURE or IF SUCCESS tests after these commands did not
work when they failed. Fixed in the next release.
725. The RENAME command sometimes fails without printing an error message
Fixed in the next release.
726. ENABLE/DISABLE QUERY broken
ENABLE QUERY or DISABLE QUERY always give a parse error. Fixed in the
next release.
727. CD command with wildcard broken
For example, "cd a*" when only only directory name begins with "a".
Fixed in the next release.
728. DIRECTORY command with multiple filespecs can list too many files
Example: "directory a b c" lists all files whose names END WITH a, b,
or c, rather than the files whose names ARE a, b, or c. Fixed in the next
release.
729. Display of Plane-1-and-beyond Unicode characters
At present, Kermit 95 can not display Unicode characters beyond Plane
0, i.e. whose code values have more than 16 significant bits.
Examples include Gothic, Old Italic, and Vietnamese Nom. This
limitation is due to the lack of support in the Windows operating
system for glyphs beyond Plane 0.
730. k95g.exe ssh://xyzcorp.com --nobars causes invalid memory reference
Fixed in the next release.
731. Long Read Delays when using USB Serial Ports or Modems
K95's device ReadIntervalTimeout parameter is set to MAXDWORD, the
intention being for the read to return immediately after the first
byte(s) arrive. But serial port drivers differ in their
interpretation of the serial port character-read timeout parameters.
When a serial port or modem uses the USB bus rather than the PCI bus,
this can result in a 500 second delay between reads unless the buffer
is filled. This is fixed in the next release.
732. Backspace Key setting in Dialer -> Keyboard might be ignored
If you have a SET KEY \127 xxx command in your K95.INI, K95SITE.INI,
or K95CUSTOM.INI file, this overrides the Backspace Key setting in the
Dialer's Keyboard Settings page, even though the Dialer script is
executed AFTER the INI file. Fixed in the next release.
733. SET PRINTER command in Dialer-generated scripts
One user reported that it takes a long time to make a connection from
the Dialer, and traced the problem to the SET PRINTER command that is
included in every Dialer connection script. The SET PRINTER command
queries Windows for a list of printers, and in this case, the query
was taking a very long time. The user deleted the default printer and
recreated it, and the problem went away.
734. Sessions Logs are always 8-bit
Session logs always record the 8th bit of each character, even when
PARITY is not NONE, and/or even when TERMINAL BYTESIZE is 7. In these
cases the 8th bit should be stripped (unless SET SESSION-LOG DEBUG is
in effect). To be fixed in a future release. In the meantime you can
use:
SET TERMINAL BYTESIZE 7
SET PRINTER /FILE:name-for-log-file
SET TERMINAL PRINT AUTO
to create a 7-bit session log.
735. Macros on Keys broken
In versions 1.1.21 through 2.1.3, when a SET [TERMINAL] KEY definition
includes a macro invocation, then pressing the key while in the
Terminal screen returns to the command screen (and in some cases might
also fail to execute the macro). A workaround would be to:
define myconnect connect /synchronous
(make the connection with SET PORT, DIAL, or SET HOST)
if success do myconnect
This is fixed in the next release.
736. FTP MGET might not fail when it should
When SET FTP ERROR-ACTION is QUIT and a file in an MGET sequence
fails, Kermit just goes on to the next file, rather than quitting and
failing. This is fixed in the next release.
737. No way to totally disable WIKSD event logging
One message written to the event log prior to the processing of the
IKSD.KSC file; thus even if IKSD.KSD says "no logging", log records
will accumulate. It is unclear at the current time when this will
occur. There is also known to be a handle leak in IKSDSVC.EXE which
can result in system instability. This is fixed in the next release.
738. OpenSSL Security holes in 0.9.7
Version 2.1.2 of Kermit 95 ships with OpenSSL 0.9.7 which contains
known security holes. These holes have been fixed in subsequent
releases. The current release is 0.9.7f. The next release of Kermit
95 will contain these fixes.
739. Kerberos for Windows updates
Version 2.1.2 of Kermit 95 ships with an outdated version of MIT
Kerberos for Windows which does not support AES encryption and
contains interoperability problems with the Microsoft Windows Active
Directory implementation of Kerberos and MIT Kerberos 5 Release 1.3.x.
The next release of Kermit 95 will contain these improvements by
including MIT Kerberos for Windows Release 2.6.
Kermit itself has been improved to support new Microsoft Kerberos
functionality including new encryption types as well as use of the
Kerberos tickets stored in the Microsoft Logon Session Kerberos cache.
740. OpenSSH Security holes
Version 2.1.2 of Kermit 95 ships with OpenSSH 3.5 support containing
known security holes. The OpenSSH support in the next release of Kermit
95 will be updated to OpenSSH 3.6.1 with extensions for SRP and GSSAPI
Kerberos.
741. SEND command in Kermit function causes crash
A SEND command embedded in a macro and executed as a function with
\Fexecute(macro) would cause K95 to crash. This is fixed in the next
release.
742. Denial of Service attack against TCP/IP SET HOST * connections
Incoming TCP/IP connections did not provide for timeouts enabling a
remote attacker to perform a denial of service attack against K95
configured to accept incoming connections. This is fixed in the next
release.
743. SSL/TLS Private Key Passphrase Dialog reveals passphrase
The passphrase dialog for private keys accessed during SSL/TLS
connection attempts does not obscure the passphrase input. This is
fixed in the next release.
744. Pragma Systems Terminal Server Not Supported
Kermit 95 has supported being used as a Kermit protocol engine under
the Pragma Systems Telnet and SSH daemons but not the Terminal Server
product. This is fixed in the next release.
745. Communication devices passed to Kermit as handles are closed on exit
Starting in the next release, if a communication device is passed to
Kermit 95 for use via an already existing HANDLE, the default for the
SET EXIT HANGUP command will be OFF.
746. SET TCP HTTP-PROXY cannot be used with HTTP connections
Support for using HTTP Proxy connections for HTTP connections has
been added to the next release.
747. UNC paths do not work during FTP operations
Support for using UNC paths with FTP operations has been added to the
next release.
748. Dialer QUICK Command improvements
The dialer QUICK command did not allow connections to be based on
existing template and could not be saved for later use. The next
release supports the use of templates in the QUICK command and allows
the command to be used as a poor man's CLONE.
749. Linux Character Set handling bugs
There are bugs in the handling of the Linux Character Set. These have
been fixed in the next release.
750. XMODEM-CRC checksums are not computed properly
The XMODEM-CRC checksum computations were not performed properly in
all instances. This has been fixed in the next release.
751. BEEP when setting window title in a terminal session
An inadvertant beep was produced when a SET TITLE control sequence was
received from the host. This is fixed in the next release.
752. NEW FEATURE: SSH Debug Logging
The next release supports the ability to log debugging messages to the
debug.log file to assist in diagnosing connection problems.
753. Telnet AUTH vs Telnet START_TLS protocol negotiation conflicts
A protocol message sequencing error could occur when connecting to
some hosts which support both the AUTH and START_TLS Telnet protocol
options. This is fixed in the next release.
754. NEW FEATURE: SSH Version 2 Protocol Automatic Rekeying
SET SSH V2 AUTO-REKEY {ON, OFF} has been added to the next release to
support automatic rekeying of long lasting ssh version 2 connections.
755. Extended command line options not properly processed
When using a mixture of Extended command line options the even
numbered options would be misinterpretted as multi-valued switches.
This would produce very odd and unexpected results. This is fixed in
the next release
756. SSH URLs did not set the window title
When starting K95 from a command line with an SSH URL or via a browser
using an SSH URL, the title of the K95 window would not be properly
set to the host name. This is fixed in the next release.
757. NEW FEATURE: SKERMIT command
The SKERMIT ssh subsystem functionality now has its own shortcut
command. No longer is it necessary to enter
SET NETWORK TYPE SSH
SET HOST host /SUBSYSTEM:SKERMIT
instead
SKERMIT host
is all that is required. This is available in the next release.
758. Process handle leak in the IKSD Service
A process handle leak in the IKSD Service could cause Windows to be
unable to start subsequent processes and/or become very sluggish.
This is fixed in the next release.
759. NEW FEATURE: FTP SSLv2 connections
K95 follows the specification for FTP AUTH SSL and FTP AUTH TLS and
does not support the antiquated SSLv2 protocol on FTP connections.
Unfortunately, not everyone else follows the specification. A new command
SET FTP BUG USE_SSL_V2 {ON, OFF}
has been added to allow SSLv2 to be used with servers that won't
negotiate SSLv3 or TLSv1. This is available in the next release.
760. NEW FEATURE: SSH Heartbeats to maintain connections through NAT/Firewalls
A new command
SET SSH HEARTBEAT-INTERVAL <seconds>
has been added to the next release to allow the SSH to be maintained
during long idle periods. This is similar to the
SET TERMINAL IDLE-ACTION TELNET-NOP
SET TERMINAL IDLE-TIMEOUT <seconds>
which can be used to preserve TELNET connections without actually
sending data to the host applications.
761. NEW FEATURE: ON_CD macro
A new auto-execute macro, ON_CD, can be defined in the next release.
This macro is executed whenever a change directory operation occurs
either due to a CD command or a Kermit protocol operation.
762. NEW FEATURE: FTP MLSD parsing of extended strings
763. SET ATTRIBUTES DATE OFF did not apply to XYZmodem file transfers
In the next release the SET ATTRIBUTES DATE OFF command can be used to
ignore the actual date information of the file and instead use the
current date/time information as the file is sent or received.
764. FTP ASCII transfers generated incorrect end of line when sending
FTP SEND file transfers of ASCII files to Unix or MacOSX hosts produce
the wrong end of line marker. This has been fixed in the next
release.
765. Unable to specify the HTTP Agent for use in Proxy Operations
Firewalls often filter HTTP requests based upon the Agent tag in the
HTTP headers. The Agent tag is supposed to indicate the requesting
application. To allow Kermit to pretend to be Netscape, Mozilla or
Internet Explorer a new
SET TCP HTTP-PROXY /AGENT:<agent-string>
option has been added. This is available in the next release.
766. Windows Registry entries containing environment variables are not
processed correctly
Windows Registry entries containing environment variables should have
the environment variables expanded before use. This is important for
roaming profiles and the locations of network available applications.
The next release of Kermit 95 will properly expand this registry
strings.
767. Reverse DNS Lookups cannot always be disabled
There are some circumstances in the SET HOST operation in which
reverse dns lookups are not always disabled by SET TCP
REVERSE-DNS-LOOKUP OFF. This is fixed in the next release.
768. Directory operations fail on network mapped file systems which do
not provide date information
Some networked mapped file systems do not provide attribute
information for directory entries. This causes the Microsoft C
Runtime Library stat() command to fail. The next version of Kermit 95
replaces all calls to C Runtime Library file routines with new
functionality implemented solely using the Win32 API.
769. IBM 3151 emulation is missing keymap assignments for some keys
The IBM 3151 emulation was missing kverbs for the Home and BackTab
keys. The I31_F21 kverb would send the output of the F11 key. These
have been fixed in the next release.
770. Dialer FTP entries did not preserve alternative port numbers
When the connection type is FTP, the port number is not entered into
the appropriate field when editing. This means that editing an
existing entry which requires an alternate port will lose the
alternate port if the GENERAL page is edited and saved. This is fixed
in the next release.
771. NEW FEATURE: Hyperlink Extensions for ANSI based terminals.
Hyperlink Extension for Terminals based on
ANSI X3.64-1979/ISO-6429/ECMA-048
The hyperlink extension utilizes the Device Control Sequence (DCS) to
implement both URL and UNC hyperlinks within the terminal session with
the equivalent of the HTML HREF tag:
<a href="http:/host/path?parameters>Click Here</a>
In an HREF tag, only the "Click Here" string is visible to the end
user. Clicking on any character in the string will result in the
execution of the URL. The DCS equivalent to the HREF tag is:
<DCS> Pn + m <link string> <ST>
where:
<DCS> is either the 8-bit DCS control or the 7-bit sequence
<ESC> P <ST> is either the 8-bit ST control or the 7-bit sequence
<ESC> \ Pn is one of three parameters:
0 terminate the hyperlink attribute
1 activate a URL hyperlink attribute
2 activate a UNC hyperlink attribute
<link string> is the link text which may optionally be surrounded
in double quotes.
Here is an example of how this extension is used to specify a URL
hyperlink associated with a text string displayed to the end user:
<DCS>1+m"http://www.kermit-project.org"<ST>Kermit Home Page<DCS>0+m<ST>
When this string is received by a supporting terminal emulator, at the
present only Kermit 95 2.2.0 or higher, a hyperlink character
attribute is defined. This character attribute behaves identically to
a Select Graphic Rendition (SGR) character attribute such as Bold,
Underline, or Reverse. Terminal emulators which do not support this
extension would only display the contents of the display string. An
example of a UNC hyperlink follows:
<DCS>2+m"\\server\path\document.pdf"<ST>Acrobat Document<DCS>0+m<ST>
The hyperlink attribute can be combined with SGR sequences to specify
display attributes for the hyperlink:
<DCS>1+m"http://www.cdaero.com"<ST><CSI>4mCD Aero Home <CSI>24m<DCS>0+m<ST>
In the above sequence a URL hyperlink is specified in combination with
the Underline SGR sequence. The display text is therefore displayed
with an underline. When the display text is printed the underline and
URL hyperlink attributes are removed. This behavior could also have
been obtained with the sequence:
<DCS>1+m"http://www.cdaero.com"<ST><CSI>4mCD Aero Home<CSI>0m
This is because the SGR 0 sequence means to clear all character
display attributes. Only one hyperlink attribute may be specified at a
time. Therefore, sequences of the following form are also valid:
<DCS>1+m"http://www.cdaero.com/index.html"<ST>Web
<DCS>2+m \\server\public_html\index.html<ST>UNC<DCS>0+m<ST>
In this sequence the URL hyperlink is replaced by a UNC hyperlink and
then hyperlink attributes are disabled. Kermit 95 2.2.0 will display
with an associated hyperlink according to the values specified with
the command:
SET TERMINAL URL-HIGHLIGHT ON <attribute list>
Where <attribute list> is one or more of: BLINK, BOLD, DIM, INVISIBLE,
ITALIC, NORMAL, REVERSE, and UNDERLINED. The default is BOLD for the
console version and BOLD UNDERLINED for the gui version. This
extension is supported in the following terminal types: AIXTERM,
ANNARBOR, ANSI-BBS, AT386, AVATAR/0+, BETERM, HFT, LINUX, QANSI,
SCOANSI, SNI-97801, SUN, VT220, VT220PC, VT320, VT320PC, WY370.
772. ANSI DCS sequences containing an intermediary '$' character are
improperly handled
the processing of all sequences with intermediate character '$' fell
through to sequences with intermediate character '|'. This could have
done very bad things to the values assigned to DEC UDKs. This has
been fixed in the next release.
773. NEW FEATURE: 3DES Telnet support
Add SET TELNET BUG AUTH-KRB5-DES which defaults to ON. When OFF, 3DES
encryption may be used with KRB5 Telnet authentication. This is added
to the next release.
774. UNC paths in file transfer operations generate errors
This bug is fixed by the same code changes as number 768.
775. SET TITLE <title-string> is not brace stripped
In the next release, braces or doublequotes may be safely placed
surrounding the title string. They will be stripped off before the
window title is applied.
776. MOVE-TO and RENAME-TO functionality did not work with XYZmodem transfers
The MOVE-TO and RENAME-TO functions were never implemented for
XYZmodem. This support has been added to the next release for both
SEND and RECEIVE operations.
777. SEND /MOVE-TO:<directory> fails when using Kermit protocol
The SEND /MOVE-TO: switch was broken. It incorrectly overwrote the file
name with the directory name. This caused a fatal error during the file
transfer. This is fixed in the next release.
778. SET TERMINAL DEBUG ON command does not work.
The command does not work but the keyboard verb \KDebug which is mapped to
Alt-D does. This is fixed in the next release.
779. The INFORMATION sound generates no audible output
The wrong system sound was being called for BEEP INFORMATION or events
which produce an informational tone. This has been fixed in the next
release.
