Hi, I am willing to deploy on my server an SSH daemon which I can control what commands can be executed, and by who. After playing with jailkit [link] I realised that implementing my own SSH server will give me more power and scalability (especially regarding of users, keys and accounts management).

Naturally I approached twisted knowing it will solve this problem as a smart kiddo solves a simple safari puzzle.

Playing with samples found on the web and at Twisted docs, I realised that twisted has everything I need for the task, but I am missing the knowledge of how to glue it all together.

In fact, a command if not working on the first strike, works on the second try.

at http://gist.github.com/37446 I pasted the server.py code. which is a modification of what I've found at: http://twistedmatrix.com/projects/conch/documentation/examples/sshsimpleserv...

for instance trying to run git over ssh yeilds error at first, and when running again seems to be working. below is the console output on the client side
