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.
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.
Paranoid TelnetD is written in straight C with few dependencies. It is intended for use with embedded or legacy devices (like the hand-scanners used in warehouses) that communicate via telnet. It features: 'telnet only' user accounts, separate from the system authentication (so only the specified usernames/passwords can login via telnet, and only via telnet); user, IP address, and MAC address whitelisting/blacklisting; chrooting with 'bind mounts' to allow access to certain directories under the chroot jail; and 'honeypot mode' in which all authentication fails and all events are logged at syslog 'crit' level.
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.
