Easy ssh to SAND

README.md

Getting easy ssh

Take the below configuration, edit in your username for both entries, and copy it into ~/.ssh/config on your local machine.

When you want to access sibu, try:

ssh sibu

And when you want to access sand, try:

ssh sand

That's you! SSHing into sand no longer requires hacking around with sibu manually. Easy.

Making it easier

It can get easier yet: you can get slippery delicious passwordless access, too.

Make sure you have ssh keys

Enter cat ~/.ssh/id_rsa.pub — if nothing gets printed, run ssh_keygen, and hit enter at any prompts.

Copy the key over

Run cat ~/.ssh/id_rsa.pub and copy it.

Run ssh sibu and then nano ~/.ssh/authorized_keys (or whatever your editor of choice is). Paste onto a new line. Save.

You should now have passwordless access to both sibu and sand!
