If you don't want to type in hostname or username while ssh'ing to a remote servers, you have several options. Let's say you want to run ssh user@192.168.178.05.

• If you are currently logged in as user on the current machine, you don't have to specify it. ssh 192.168.178.05 works.
• If you find it hard to type that address, you can give it an alias. Do this:

File: /etc/hosts
...
192.168.178.05 desktop

ssh desktop
# or
ssh user@desktop

• If you want to give username and host an alias:

File: ~/.ssh/config
...
Host myremote             # any name for the host
HostName 192.168.178.05   # IP, .local, or hostname if defined
User username             # your username
Port 22                   # port to listen

ssh myremote
