Using telnet to manage firewalls?  Tsk-tsk.  :-)

The problem is either that:

1) Cisco routers and firewalls by default skip the standard "login:"
prompt most telnet servers offer up and go right to "Password:"  Use
the 'pix' directive in your snortsam conf file instead:

pix [telnetpass] [enablesecret] [config]

2) You *are* using the pix directive and you have AAA user
authentication turned on on the PIX and it *is* generating a "login:"
prompt.  Use:

pix [user]/[password] [enablesecret] [config]

Seriously, though, I would consider building Snort with flexresp and
modifying those rules that pertain to you to fire off ICMP type 3 or
TCP RST packets that will cause whatever firewall to drop the
connection.  Then you can turn telnet off. :-)
