Firstly a belated thanks to everyone who replied to my previous question – I had to put my project on hold for a while, but now I am back with more questions.
My objective is to use twisted to do automated logging in to multiple ssh servers to carry out various tasks. Currently this is done by spawning a separate ssh executable for each session and controlling it through pexpect, and I would like to replace this with a twisted/conch system.
Hi Dave, The framework I created to do something very similar to this is available for free at http://modipy.seafelt.com. ModiPY is written using twisted and currently does pretty much what you've described, spawning a program in a sub-process to do work. This 'spawn and do work' component could be replaced by a conch SSH client instead. In fact, this would be desirable for some things.
So far I can create conch “exec” sessions to run a single command/script and return the result, but I would like to be able to create shell sessions and do more interactive work. Does anyone have any examples of doing this?
I'm guessing you want examples of how to use conch to do interactive work, so ModiPY probably isn't useful here, but you might be able to use some of the ideas in the ConnectingProvisioner and ExpectProtocol. It connects to a remote device and runs a series of commands, handling their output. -- Justin Warren <daedalus@eigenmagic.com>
