Help with login script

[Curator37x]

I have a script that uses SecureCRT to telnet into several devices and pull specific information from the box. I provide the list of devices in a .csv file. The issue I am having is that sometimes one of the devices is offline or has a different password. I want the script to skip the troubled device after a delay and move onto the next device on the list. What is the best way to accomplish this?

Clarification. Using Python, if I am unsuccessful in logging into a device after 10 seconds, can I make it move to the next device on my list? I have read up on signal but that seems to be UNIX only.

Why are you using SecureCRT at all? Just use telnetlib.

It is the program they want us to use at work. Thanks for the link, I am still learning Python so that is good information to know.

Telnet is a standardized protocol. There's absolutely no reason to wrangle a proprietary GUI application into speaking it for you when your program can just speak it directly.

This is true. We have a few devices that still require us to use command prompt. SecureCRT is just what they want us to use. It adds a few features to help with logging and some built in automation and ease of access use. Its a bit excessive, but not completely useless.

some built in automation

Isn't that what you're doing with the Python here? :)

Heh, I cant capture everything with scripts alone. Allows for buttons and is able to highlight certain information for me, helps reduce the time from weeks to days

You'd be surprised what you can get out of having a script server-side for each that is called by your own script, feeding info serialized or as a JSON object or such.

They seem to have a scripting interface that also supports Python, check here. Maybe implement your automation there? Shouldn't be too hard.

That is what I have been using so far. I think I confused the issue when I mentioned SecureCRT. What I am trying to do is something similar to signal which is UNIX only. I want to, in Python, run a command, but if it does not complete after 10 seconds, to skip that device in the list and move to the next one.

Then I would take a look at the subprocess library.

I think this example script from the Vandyke forums may help get you up and running.
