+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
+```
