RE: changing routers and switchs passwords remotely

5 types of devices.  In our case we have about 50 routers, but two
different models only, so it's no issue.  Another thing you could use is
the telnet scripting tool.  Just google for it, it's used to script
telnet sessions (duh), so you just have to make one script for each type
of switch.

I had looked at this program in the past myself, but there are enough
limitations on the freeware version to limit its usefulness in a larger
network.  According to the web site, here are the limiteations:

The Freeware edition of Kiwi CatTools supports: 
        Up to 5 devices in the device database 
        Up to 5 scheduled activities 
        Up to 2 simultaneous TFTP sessions 
        Single threaded operation

Since he said there are 80 switches, the Freeware edition would not be
feasible.  To handle this many devices, he would need to purchase the
Professional edition, which sells for $149.

Just my $.02 worth.

Taken from the site:

Kiwi CatTools is a freeware application that provides automated device
configuration management on routers, switches and firewalls.

Support is provided for Cisco / 3Com / Extreme / Foundry / HP /
Netscreen / Multicom devices and more.

Some of the many tasks Kiwi CatTools perform to make your life easier

    * Perform configuration backups and have any differences instantly
e-mailed to you.
    * Issue commands via Telnet or SSH to many devices at once.
    * Change the configuration at scheduled times.
    * Change all your network device passwords in one go.

This configuration management tool is also fully scriptable, has a
built-in TFTP server, supports SSH, Telnet and more.


We use it, and it works great on any device you can telnet to, as long
as it's command-line control.

Another way would be to find the SNMP ID of the admin password and use
the write community to modify the value, although freeware for this is
pretty cheap and finding the SNMP info is pretty complex if you've never
done it before.
