[auton-users] Managing ssh key using keychain

[Donghan (Jarod) Wang]

Hello lab,

This message describes how to use keychain to allow ssh access from one
host to another without typing password or passphrase in secure way. It
comes in handy in many scenarios, such as cvs operations, ssh from lops to
low1.

It requires a private/public ssh key pair. You can check its existence by
looking into your ssh files, specifically, id_rsa.pub and id_rsa; by
default they are in

/auton/home/<user>/.ssh/
/neill/home/<user>/.ssh/
or /home/<user>/.ssh/

So you have your ssh keys ready (if not, check out this tutorial
http://www.autonlab.org/auton_intranet/skills/sshkeys.html)

Simply append following line to the shell startup file, .bashrc for bash
and zsh and .cshrc for c shell and tcsh.

eval `keychain --eval --agents ssh id_rsa`

That's it.

Let me know if you have any questions. Enjoy,

Jarod
