SSH Config
SSH client config file manager
What is ssh_config?
https://linux.die.net/man/5/ssh_config
Why
I don't remember all the servers I am managing. Also all servers require all different configurations to connect to it. I know ~.ssh/config can handle this kind of issue. I want it to handle this file easier.
Yes, I am not sure this is easier way to handle it. but I am trying.
