hi cisco gurus!
I'm having an issue trying to ssh from my 4900 to a linux pc.I can ping to the host, in fact the 4900 is de DG of the the network.
The thing is when I run an ssh I can't connect. It's not a firewall stuff. Any idea
switch4900m#ssh -v 2 -l mariano 192.168.4.17
% Connection timed out; remote host not responding
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.4.17, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
Sorry, that command did not work for me
switch4900m#ssh -v 2 firstname.lastname@example.org
% Unknown command or computer name, or unable to find computer address
switch4900m#sh ip ssh
