mcl is a MUD client running in a Virtual Console under Linux or using standard TTY routines under any other UNIX. Embedded Perl or Python offer very high tweakability. Other features include huge scrollback, a stable input line with the MUD prompt, Perl regexps for actions and substitutions.
SMSTerm is an application that uses the ICQ2000 protocol to present you a shell on your mobile phone which allows you to interact with your computer from any mobile on a GSM network. It runs a shell on a pty, and allows you to directly send commands to the shell through SMS. Minimal authentication is done over SMS before spawning a shell and offering it to the user on the mobile phone. It is very useful for remote administration tasks, or checking out the status of the network, or just to run some small chores on your system while you are away. It uses Expect.pm in the background. SMSTerm also includes a script to send SMS through the ICQ network from the command line to any GSM mobile, and also includes a PHP script to set up a Web->SMS gateway.
Zuul was yet another PHP frontend for mldonkey. It has been out-of-sync with current mldonkey development for some time, however, and exists now only as a reference for the more current fork of the project, Web-GMUI. Zuul is unlikely to function properly against any available mldonkey releases, so file releases are unavailable at this time. CVS from sourceforge is still available, however.
ssh-multiadd adds multiple ssh keys to the ssh authentication agent. These may use the same passphrase. When run without arguments, it adds $HOME/.ssh/identity and $HOME/.ssh/id_dsa. Alternative file names can be given on the command line or in the configuration file. It uses ssh-askpass if necessary. Unlike ssh-add, if any of the keys use the same passphrase, you will only need to enter each unique passphrase once, and keys that are already added will not be prompted for again.
Secure Back Door (SBD) is a tool that provides ultra-secure and minimal access to a computer, which allows you to run a single command based on a one time key. It is good if you don't want to have an SSH server running all the time, and only want to start it when needed. Because it is written in only a few lines of code, it is hoped that it will be less susceptible to security exploits than a program like SSH.
zssh (Zmodem SSH) is a program for interactively transferring files to a remote machine while using the secure shell (ssh). It is intended to be a convenient alternative to scp, allowing to transfer files without having to open another session and re-authenticate oneself. zssh is an interactive wrapper for ssh used to switch the ssh connection between the remote shell and file transfers. Files are transferred through the zmodem protocol, using the rz and sz commands.
