SSH is one of the tool for every sysadmin or developer and is important to master at best.
Right now I am using few settings that improved my daily life with my servers.
Auto forward ports on logging to a server
Host your-host LocalForward 9090 localhost:9090 LocalForward 9271 localhost:9271 LocalForward 9217 localhost:9217 LocalForward 9100 localhost:9100
Set a default user for a specific host
Host another-host User daniele
Create an alias
Host well-another-test.fake Hostname 255.255.255.255 User awesomeuser IdentityFile ~/.ssh/keyfile port 2222 IdentitiesOnly yes
This can be used with as host the fake one.
