I have Python code that opens a telnet session with a network device and performs a multitude of tasks. Now, I am trying to establish and maintain an SSH connection as an alternative to telent. My research has found that the SSH implementation some network device manufacturers use is not consistent and the problems I'm having are common. I'm hoping to find someone who has found a solution.
I am using Paramiko, but I am not limited to that. I am also exploring Appgate "MindTerm" http://www.appgate.com/index/products/mindterm/. My Paramiko code works correctly when connecting with a Linux system. But when I connect with a router, the connection is dropped immediately after a command is exectued, so it isn't possible to send a sequence of interrelated commands. For example, I want to change the screen paging value so that complete results from the next command will stream back without stopping for "--MORE--". Or I need to change the user level and enter a password followed by a series of commands. I have reviewed relevant postings from on the Paramiko list, but there are no clear solutions. http://www.lag.net/pipermail/paramiko/2010-June/001322.html http://www.lag.net/pipermail/paramiko/2010-June/001320.html http://www.lag.net/pipermail/paramiko/2010-March/001284.html I have tried three methods, unsuccessfully, for establishing and maintaining an SSH connection. My test code is at http://pastebin.ca/1918235. I would appreciate any help. I'm open to a non-Paramiko solution, but it has to plug-and-play with the Python utility code I already have. And I hope to keep it simple. Thank you, David Heiser
