[ILUG] rsh/ssh (or: the ongoing battle with rawhide)

[Stephen Shirley]

RSA auth is very easy to setup. Here are the few steps needed:

1. Run ssh-keygen on your workstation, if you haven't done it already.
   Enter whatever passphrase you want (not blank - baaaad idea).

2. Copy your .ssh/identity.pub to the server using 
   scp ~/.ssh/identity.pub username at server:

3. Ssh to the server, and append that file to .ssh/authorized_keys

4. On your workstation run 
   eval `ssh-agent`
   ssh-add
   
RSA auth now works - try 
   ssh server
You won't get asked for a passwd :-)
You won't have to enter the passphrase again until
you reboot your workstation. Now to get it all working
automatically in every shell you use, put the following in your
.bash_profile:

touch ~/.ssh/pid 
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                                  

And bobs your uncle. If you have any q's just give me a shout.
