If you’re like some people and have a hard time remembering exactly how to ssh into ColonialOne, it may be a good idea for you add an alias to your .bash_profile.
An alias is a substitute for a complete command, like a shortcut.
You can make an alias so that you only have to type colone instead of typing ssh username@login.colonialone.gwu.edu every time you log in to ColonialOne.
First, make sure you are in the home directory of your own computer (not on ColonialOne). Use the command cd ~.
Use the command ls -a to see your hidden files (those with . in front of them). You should see a file called .bash_profile.
Use a text editor like vim or nano to add the following line to the file .bash_profile:
alias colone='ssh username@login.colonialone.gwu.edu'
Type . .bash_profile to reload .bash_profile and update any functions you add.
You should now be able to type colone and get into ColonialOne.
Note: GW is currently transitioning to Pegasus. You may wish to create an alias to connect to pegasus by adding the following to your .bash_profile file:
alias pegasus='ssh username@pegasus.colonialone.gwu.edu'
