* Release 2.5.3
Fix file descriptor leak when IP address lookup fails.
Fix problem with running a server in "reverse" mode and detached -- only
apparent on Windows.
Add "maxconnections" to alleviate DoS attack.
Check for target port 0 to avoid DoS.
Linux 64-bit port (a result of the "Linux on POWER" contest) courtesy of
Stew Benedict <stewb@linuxcontrol.net>. Use the "linux64" OS target.
Upgraded version of bzip2 and zlib.
Cross-platform fix for checksumming code. This is
*incompatible* with version 2.5.1. As a temporary
workaround, setting "bugcompatibility 251" will maintain
compatibility with release 2.5.1 for little-endian platforms
(e.g. Intel). This will be removed from the final production
release.
Upgrade to Inno Setup 4.
More documentation fixes.
Increased the default thread stack size to 64k and
added "threadstacksize" for debug/test purposes.
Fix handling of HTTP/1.1 responses from proxies.
Added acceptconnecttimeout (supersedes "connecttimeout")
along with connectattempts, serverconnecttimeout and
targetconnecttimeout.
Fixed bug with "clienthost" not being honoured when Zebedee
was used as a service.
- USE_GMAKE.
- use tcl's buildlink.mk.
* Release 2.3.1 (2002/03/15)
Changed any potentially unsafe sprintf/vsprintf instances to
snprintf/vsnprintf. There should never have been a remote exploit possible,
this just eliminates any theoretical local ones in case someone has a reason
to run this as root ... (Note that use of these functions may be an issue
on some platforms although they do appear in the UNIX98 spec and exist
on Windows).
Allowed CIDR address specifications for target (and server name in listenmode).
Added IP address checking with the "checkaddress" keyword.
Finally caved in and added "httpproxy" to allow connection via a web proxy
server using "CONNECT".
Added "transparent" keyword to attempt to act as a transparent proxy and
forward on the client IP address. It may work on Linux 2.0/2.2. But then
again, it might not ...
* Release 2.3.0 (2002/03/07)
New functionality (at last!).
Added "listenip" and -b option to set listening address.
Added "tcptimeout" and "idletimeout" to allow inactive TCP tunnels to be
closed.
Added "ipmode" and -U option to support mixed traffic mode for a single
client or server.
Makefile changes for Irix and HPUX from Kyle Dent. Others to use latest
version of mingw gcc and force use of "native" perl.
Note that Zebedee will now be linked with MSVCRT.DLL. That should only
be a problem on an old Win95 machine.
Japanese documentation NOT YET updated.
for systems where the dependent libraries aren't part of the base system.
Don't include tcl/buildlink.mk as the libraries aren't required for the
build -- only the tclsh binary is required at run-time. Also honor CFLAGS
passed in from environment during the build.
Zebedee Secure Tunnel
=====================
Zebedee is a simple program to establish an encrypted, compressed
"tunnel" for TCP/IP or UDP traffic between two systems. This
allows data from, for example, telnet, ftp and X sessions to be
protected from snooping. You can also use compression, either
with or without data encryption, to gain performance over
low-bandwidth networks.
The main goals for Zebedee are to:
* Provide client and server functionality under both UNIX
and Windows 95/98/NT.
* Be easy to install, use and maintain with little or no
configuration required.
* Have a small footprint, low wire protocol overhead and
give significant traffic reduction by the use of
compression.
* Use only algorithms that are either unpatented or for
which the patent has expired.
* Be entirely free for commercial or non-commercial use and
distributed under the term of the GNU General Public
Licence (see LICENCE.txt for details).
For further information on how to use Zebedee see the file
zebedee.html in the distribution (or the manual page for
zebedee(1) under UNIX -- it is basically the same text). Example
configuration files are also provided.
