Can you access the routers with telnet or do you need to use ssh? I've
written loads of Python to access Cisco routers using a wrapper around
the standard telnetlib. Telnetlib supplies an excellent expect
function which makes this work.

It is telnet, though. If I had to use ssh I would probably add it
under the same wrapper so that higher level code could work unchanged.
There may be a way to route the telnet interractions through openssh
or similar externally but I haven't tried that.
