#66674 — SSH/Telnet program to Router/switch

Hi,

I am new to programming and python. I am looking for a python script to do ssh/telnet to a network equipment ? I know tcl/perl does this using expect/send. 

Do we have expect available in python as well or need to use some other method ?

Regards
Sujith

Yep! Look up the socket module. Straight-forward TCP sockets are
usually easy enough to work.

Hello,
 If you are looking for a way to connect to your netdevices and then
execute some shell commands (with output) via ssh then google for
paramiko module for python.

It works on windows and linux.

Hello,

What will benefit the OP to go ahead and use paramiko opposed to just use "Putty" or another perhaps even Chrome based ssh client?

Is there an advantage to that?

This is a Python mailing list so obviously the OP wants to use python to automate logging into his devices and dispatching some commands. Why else would they ask here?

I'm using paramiko to access some routers and firewalls from python and 
it works very well.

You want two libraries.

First, the low-level paramiko (http://www.lag.net/paramiko/) which 
handles all the basic ssh connection stuff.

Next, fabric (http://docs.fabfile.org/en/1.8/), which layers a very easy 
to use application layer on top of paramiko.  Fabric is most commonly 
used in conjunction with a near command-line driver tool called fab, but 
you can also work directly with the library layer 
(http://docs.fabfile.org/en/1.8/usage/library.html).

Fabric rocks.  Don't waste your time with anything else (but see the 
next paragraph).

As far as I know, fabric only works with ssh.  If you are forced to use 
telnet to talk to legacy equipment, that's another problem.

If it's telnet, it's likely to be a pretty simple protocol. All you
really need is the socket module, build it all yourself. Networking's
easy enough to handle; it's the crypto on top of it (SSH, in your
case) that's not worth doing manually.

Typo there: "near" should have been "neat".

[this is why I love wikis]

In addition to the other answers you've received (and noting that you are familiar with "expect"), you might want to investigate the pexpect module. Google will give you quite a long list of references to it, but you could start here:  http://pexpect.readthedocs.org/en/latest/
