PortMapper
Added 2001-10-22
by AnalogX
AnalogX PortMapper allows you to map any port on your computer to any IP address and port on another machine; not only that, you can limit access based on the incoming IP address! So, say for instance that you are using a proxy, and would like to be able to telnet from other machines; simple, just run PortMapper, and tell it to forward any request to port 23 (telnet) to the machine you want to access. Now, any time you telnet to your proxy server machine, it automatically forwards the data to the other machine! Or, do you run a webserver, and only want people from IP address you specify to connect? No problem, PortMapper can do that as well!

Leapfrog for Win32
Added 2001-10-22
by COTSE, webs@cotse.com
Leapfrog will anonymize and redirect (bounce) any port. It can be used to work around firewall configuration and other issues requiring a port redirect. Leapfrog can be chained, reconfigured on the fly, and customized to change ports/machine redirects without the need to log into the box. It can be configured (with little work) to remove all traces of itself from disk after being loaded, or it can be configured to log everything (default). It supports colors and some basic admin tools. It is very fast. Version 1.2 Adds a config file for setting the port that LeapFrog will bind and listen on. Version 1.2 also adds the ability to (by a config variable) make leapfrog a detached process (run in the background under 95/98/nt/2000). Version 1.2 has added some new logging facility

MindTerm
Added 2001-10-22
by Mats Andersson, mindterm@mindbright.se
MindTerm is a complete ssh-client in pure Java. It can be used either as a standalone Java application or as a Java applet. Three packages of importance are provided (terminal, ssh, and security). The terminal package is a rather complete vt102/xterm-terminal, and the ssh-package contains the ssh- protocol and also "drop-in" socket replacements to use ssh-tunnels transparently from a Java application/applet. It also contains functionality to realize a ssh-server. Finally, the security package contains RSA, DES, 3DES, Blowfish, IDEA, and RC4 ciphers.

TapTunnel
Added 2001-10-22
by Lennart Poettering, poettering@gmx.net
TapTunnel is a client and server for creating Ethernet tunnels over TCP/IP-networks (such as the Internet). It can be used to connect two private networks over a public one. It uses raw-ethernet, and therefore can tunnel a variety of protocols (IPX, ARP, IPv4, IPv6, DHCP, etc).

OpenSSH Challenge/Response patch
Added 2001-10-22
by Igmar Palsenberg, cryptocard@jdimedia.nl
The OpenSSH Challenge/Response patch integrates Challenge/Response authentication in OpenSSH. This makes it possible to use hardware tokens with for example FreeBSD. Configuration is done with additional configuration directives. Please note that this patch does not use PAM, it's a native implementation.

cryptcat for Linux
Added 2001-10-22
by jojo, jojo@farm9.com
Cryptcat is the standard netcat enhanced with twofish encryption. Ports for WIndows NT and Linux exist at http://www.farm9.com Twofish is courtesy of counterpane, and cryptix. We started with the Java version of twofish from cryptix, converted it to C++ (don't ask why), and enhanced it by adding CBC mode and the ciphertext stealing technique from Applied Cryptography (pg. 196).

KSSH
Added 2001-10-22
by Andrea Rizzi and Kevin Lo
KSSH is a simple KDE front-end for Secure Shell (ssh). It calls a terminal where it will execute an ssh call based on user-specified parameters (host, username, port, etc.).

RelayTCP
Added 2001-10-22
by DLC Sistemas
RelayTCP allows to redirect TCP/IP connections from a local port to a remote IP and port. Relay TCP has the capacity to record all the connections made and the data transferred. It's useful for transferred data debuggin purposes

Added 2001-10-22
by SmartLine, Inc.
RASLock Millennium Edition is a client/server tool that enables to set user-level security for the Internet Dial-Up (RAS) connections. Using RASLock Me you can limit incoming and outgoing traffic, limit time online and set allowed/denied time periods for any user on a Windows 95/98/Me. It enhances the standard Windows security by allowing you to control the Internet access via modems (standard, ISDN, etc.).
