hi...

if i have a machine that i want to be able to automatically ssh into multiple child machines within the network, do i have to create a key for the parent machine, and supply the key to the child machines, or do i create a key for each child machine, and supply the keys to the parent?

thanks

If you want your main server to ssh to child servers, all you need is a key on the main server and than you share the .pub key ... and not the private key.

ssh-keygen -t dsa|rsa leave everything blank unless you want to encrypt the keys with a paraphrase and start to use ssh-agent

Than put the public key in /home/user/.ssh/authorized_keys2 on each child and you should be pretty much all set.

manually connect at least once to make sure it all works like you intended to as a crontab script might take a while before it types in the " yes " or even worse a password !
