This is mostly a repost of LaoTsao's Weblog with some tweaks. Last time that I tried to cut & paste directly off of his page, some of

================If not already present, create a ssh key on you laptop================
# ssh-keygen -t rsa

Enable passwordless ssh from my laptop.
Need to type in
the root password for
the remote machines. Then, I no longer need to type in
the password when I ssh or scp from my
laptop to servers.

for server in `cat servers.txt`
do
echo root@$server
cat ~/.ssh/id_rsa.pub | ssh root@$server "cat >>
