Hello All,
I havn't been programming with python too long, but decided the best way to learn it would be to dive right in. Right now I have been taking snippets here and there along with modifying some code in between to create some programs. The one I am currently doing requires me to ssh to a raritan, choose one of the cisco devices ( a router in this case) and shut down or bring up the interface based on the check boxes selected. My issue is that pexpect keeps timing out with an error when i go into the cisco device. I have a feeling it has something to do with the prompt expected, but I am not sure. Here is the code below of what I currently have. Any help or comments would be appreciated.
Make note, ignore the ip address field. Right now I hard coded everything just to ensure it works. -
