[CSC 435] Setting up SSH keyfiles on cluster

[Andrew J. Pounds]

Okay -- here is what we need to do... 

-- First get rid of the stuff we did last week using the following 
procedure...

1. log onto zeus
2. issue the comand "rm sshkey*"
3. cd .ssh
4. issue the command "rm auth*"

Now we are going to make a single ssh-key authentication file (unique to 
your userid)

5. issue the command "ssh-keygen -q -f sshkey_zeus -t dsa"

This will create two files, sshkey_zeus and sshkey_zeus.pub

6. cp sshkey_zeus id_dsa
7. cp sshkey_zeus.pub authorized_keys
8. chmod go-rws id_dsa

At this point you should be able to log into zeus from zeus with no 
password, we need to replicate this information to all the other machines...

9. cd ..
10. ./generatekeys.pl    <-- execute my perl script you copied last week
11. cat sshkey*.pub >>./.ssh/authorized_keys
12. rm sshkey*

At this point, you should be able to log into any machine in Room 306 
without a password
