I can't access a server via ssh from a specific client.
server ssh is working fine because I can access it from another clients
client machine is working fine because I can access all other servers from it
I try to debug using -vvv but I got no response:
josir@casa2:~/bin$ ssh -vvv [email protected]

Client (192.168.0.34) and Server (192.168.0.20) are on the same network.
How can I debug to find where the problem is?
