how how do you alias a ssh host nome?

[*DEAD*]

hi, i know this can be done because i always see people doing it but i cant seem to work out how. instead of typing user@host.com evertime i ssh in, ive seen people type
ssh alias
and it connects to host.com.
does anyone know what file and to edit it and what it must contain

[karmatronic]

man ssh_config
basically , you need to edit ~/.ssh/config and for a host you want alias as your_alias , you would add

Host=your_alias
Hostname=host.com
User=your_user_name
#IdentityFile=~/.ssh/home_rsa

you can then type ssh your_alias
or simply your_alias if you add the following bash alias in your .bashrc
alias your_alias='ssh your_alias'
