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.
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.
MudMagic Mud Client is a GTK/GNOME multi-platform MUD client. It provides aliases, triggers, multiple connections, plugins, MCCP, ZMP, MSP, tabbed sessions, ANSI color, and a game list that can be updated from mudmagic.com. It is configurable on a per-session basis. Plugins include an automapper, database, and note pad.
Exscript is a scripting language for automating network connections over protocols such as Telnet or SSH. It is in some ways comparable to Expect, but has some unique features that make it a lot easier to use and understand for non-developers. It supports parallelization, logging, authentication mechanisms, and a lot more.
ansistego provides terminal-level steganography for scripts and other ASCII files (ie, protection against 'cat'). It intersperses a text/script with commented ANSI codes that cause most terminals to clear sensitive lines as soon as they are written. Only a specified front text appears. The front text is embedded in the script using ANSI-cloaked comments, so that the text appears unaltered when the script is viewed with cat, but the script can be run without any decoding stage.
