[c-nsp] Cisco/HP 3020 refuses telnet

[matthew zeier]

I have a Cisco/HP 3020 blade chassis switch that all of a sudden stopped 
accepting telnet (because rancid started to fail config checks).

Short of rebooting I'm not sure how to fix.  I can login on the console 
(using tacacs auth of all things, so IP works) and can ping it.  But 
telnet gives a connection refused.  I've even go so far as changing the 
IP address on fa0.

Any clues/ideas?
