Create shortcuts for frequently accessed servers

Life is too short, that’s why it’s mandatory to use shortcuts… Instead of typing frequently used ssh client options such as port, user, hostname, identity-file and so on, you can save that information in sshd config file and then access it with defined alias.

  • System wide config file location is /etc/ssh/ssh_config
  • User specific config file location is ~/.ssh/config same as $HOME/.ssh/config

Instead of connecting to the server everytime using the following command:

# ssh root@95.80.12.10 -i ~/.ssh/my_id_rsa

Save the following entries in ~/.ssh/config file:

# vim ~/.ssh/config
Host my_db
HostName 95.80.12.10
IdentityFile ~/.ssh/my_id_rsa
User root

And connect to the server using this simple way:

# ssh my_db
