If you are running Ciscosecure or whatever they call the
authentication server these days that server should have
logs and a view of currently connected users.  If you want
to do it on the cheap, you can configure the cisco to accept
rsh commands from the Linux box IP address and send scripted
commands from there.  Just keep in mind that IP address based
security is pretty weak.  Some versions of IOS also allow ssh.
If you want an even more 'brute force' approach you can do
a scripted login/chat over telnet using either expect or
kermit.  If the linux box and access server are reasonably
close you can use a serial line to the console port and
have scripted or manual access with kermit.
