SSH Issue from PC to Server through Cisco 4500

the user and the pc are on different vlans but they are both connected to the same 4500 switch.

The user said he was able to reach the server at one time.

I can ping the server from the pc.

I cannot ssh from the pc to the server through the 4500.

I can ssh from the 4500 to the server.

There are no ACLs on the 4500.

Any ideas??

Thank you

Re: SSH Issue from PC to Server through Cisco 4500

If no acls then the switch should have no bearing . Different SSH versions on the devices ???

Re: SSH Issue from PC to Server through Cisco 4500

the switch is using version 1.99 and i can ssh to the server from there.

only when im on my pc i cant ssh. im on a different vlan than the server, but both my pc and the server are directly connected to the switch and i can ping the server from my pc.

Just to add to the madness, when I do a traceroute from another switch not directly connected to the server, I get a bunch of question marks. I can however ping the server address.

Hi

1. Please let me know whether you are trying to do the ssh to ip address of server or name of the server. If name please try to do with ip address of server.

2. What is the output of this command

telnet 22 if it is blank screen we should check in the sever policies.

Re: SSH Issue from PC to Server through Cisco 4500

I'm using the ip when trying to ssh. I'll check the results of the telnet test when I get to work. What would that test result tell me exactly?

Re: SSH Issue from PC to Server through Cisco 4500

The command telnet 22

is trying to telnet port 22 (ssh).

If you are getting blank screen after u enter this command means there is no problem on your switch and we can start checking the policies on server side.

telnet XX.XXX.XXX.40 22

Connecting To XX.XXX.X.40...Could not open connection to the host, on port 22:
