It is possible to save the configuration of an SSH connection for later usage. For example, one had to type
1ssh <username>@<ip address> -p <port> -i <path to key file>
every time one wants to connect to the server.
Create ~/.ssh/config with the following content:
1Host <name>
2 Hostname <ip address>
3 Port <port>
4 User <username>
5 IdentityFile <path to key file (if any)>
Now just type
1ssh <name>
to connect to the server.
