SSH Configuration

Possible Steps to Check the Configuration
1) ssh -v -v -v
To increase the verbosiy, some vs will take ssh -vvv
2) pgrep sshd
To make sure the daemon/server service is running if it return a process ID
3) /etc/ssh/sshd_config
To determine which port is in use for the ssh communication
4) Make link between ~/.ssh/authorized_keys to ~/.ssh/authorized_keys2
To ensure both protocol will grap the keys either way (SSH has 2 protocol, 1 & 2)
5) Trying "cat"ing the key instead of "cp"ing the keys as the later might change the format.
