Hereis how to do it:
ssh-keygen: password-less SSH login
Oh & when you are generating the key DO NOT enter any passphrase, just press return.
I got that, but I still don't see anything that says this works for multiple accounts. So, if I'm logged in to box1 as "dreamwarrior" and do the ssh-keygen, then I put the key file on box2 and try to do: "ssh user1@box2" it won't see "dreamwarrior's" key. Or am I misunderstanding something here? Can I put the "dreamwarrior" key on box2 in a location that allows ssh for ANY user? I would love it if "ssh box2" as dreamwarrior would work, but the fact is the "dreamwarrior" account on box2 won't have access to the "user1" files I need, so the scp will fail for permissions.

Hello all, I am trying to create n child processes and control them from a parent process; say make child 3 print its pid and then child 5 do the same and some other stuff. Is there a way to accomplishing this after all the child processes are created via a call to fork().
Thank you,

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be
enabled, unless you've done some clever use of multiple identities)
It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth-
erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration).
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary)
