[ILUG] Handy ssh-setting-up script

[Stephen Shirley]

Mornin',
	I have a number of linux boxes that I access
every day, and ssh is installed on them all. I discovered (as you all
probably did a _long_ time before me :-) that you can set it up that you
only have to type your password twice, and then you can access all the
machines without having to bother again - once to log in to the first
machine, and once to set up the RSA identity. Here's the short piece of
script I just put in my .bash_profile :

#---------------------------------------
TEST=`ps \`cat .ssh/pid\` | tail -1 | cut -c 28-`

if [ $TEST != 'ssh-agent' ]; then
        eval `ssh-agent | tee .ssh/shell`
        ssh-add
        echo $SSH_AGENT_PID > .ssh/pid
else
        source .ssh/shell
fi
#---------------------------------------

It's very simple - .ssh/pid holds the process id of the current ssh-agent,
and .ssh/shell contains the enviroment variables needed to set it up.
Dunno if this is of any use to anyone else, but it makes me happy :-)
