WmConsole is a console server for Windows Mobile devices which listen over BlueTooth RFCOMM channels. It allows the user to interact with the device using a commandline interface from a Linux or Windows workstation. You need the QTTY Linux/Windows client to access a WmConsole server.
The d command runs a command in the background and redirects its output to a file. The output file is annotated with start and end time, the actual command used, cwd, host, etc. You can ask the d command to extract the last command from the output file and run it again, you can ask it to append to the file or not, and other goodies. It comes with handy little programs to look at the output, tail it, etc. It is sort of trivial, but has been streamlined over many years.
WebSH is a script that executes commands on a remote machine through Web requests. This script currently only works for Unix based servers and Unix based clients. It emphasizes the fact that a vulnerability that allows a file to be edited or uploaded is just as bad as a buffer overflow of PHP or an Apache thread.
Soicmp consists of a server and a client. It allows a user to connect to a remote shell daemon by using the ICMP protocol instead of TCP. Entirely written in Python, soicmp is a working proof-of-concept to demonstrate that data can be transmitted across a network by hiding it in traffic that normally does not contain payloads.
CODESH (COllaborative DEvelopment SHell) is an automatic persistent logbook for sessions of personal command line work. It records what and how is being done, for private use/reuse and for sharing selected parts with collaborators. It is an intelligent shell that automatically logs user's shell sessions. Sessions are uniquely tagged and stored in local or distributed backend repositories (ASCII flat file or Subversion or CVS based) and can be extracted and reproduced at any time by the user who created the session or by collaborators located anywhere in the world.
