Instead of ssh, you could use telnet to connect to the Cisco router
(which incidentally runs on port 23, but is likely to be disabled on
the cisco router, unless you have a pre-SSH capable IOS running on it
(like my old cisco crap :( ) ), because i strongly doubt you have
written or are willing to write your own encryption libraries for this
project, you might also want to read IETF RFC 854
[http://tools.ietf.org/html/rfc854] about the telnet protocol, as you
are writing your own client, and not using a pre-made one, judging
from your script.
Or if you do not like the idea of sending clear-text passwords to the
router, you might want to learn about proc_open() (or popen()) and use
the native ssh utility that most likely is present on the server,
taking great care to READ THE MANUAL for the ssh command, because you
most likely do _not_ want it to spit out ANSI-escapes to you script.
