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.
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.
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.
Playlist Warlock is a text-based frontend for mpg123 written in Perl. It is intended to provide users with the playlist browsing and song selection of a GUI MP3 player from any terminal. It provides a combination of Winamp/XMMS, vi/less, and Unix prompt-style commands for creating, editing, sorting, and navigating MP3 playlists. Using mpg123 as a backend, PLWarlock allows the user to easily browse playlists and play MP3s. It supports contiguous and random play, simple jump-to-song syntax, sorting by filename/path+filename, and all the other commands you've come to expect from a good MP3 player.
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.
