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 the XML was messed up.
I run this from my MacBook. It should also work from your windows laptop if you use cygwin.
================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.
================ #!/usr/bin/env bash
for server in `cat servers.txt`
do
echo root@$server
cat ~/.ssh/id_rsa.pub | ssh root@$server "cat >>
.ssh/authorized_keys"
