If you use Mac OS X or some other *nix variant that doesn't come with ssh-copy-id, this one-liner will allow you to add your public key to a remote machine so you can subsequently ssh to that machine without a password.

cat ~/.ssh/id_rsa.pub | ssh <REMOTE> "(cat > tmp.pubkey ; mkdir -p .ssh ; touch .ssh/authorized_keys ; sed -i.bak -e '/$(awk '{print $NF}' ~/.ssh/id_rsa.pub)/d' .ssh/authorized_keys; cat tmp.pubkey >> .ssh/authorized_keys; rm tmp.pubkey)"

This one is a bit more robust -- the remote machine may not have an .ssh directory, and it may not have an authorized_keys file, but if it does already, and you want to replace your ssh public key for some reason, this will work in that case as well, without duplicating the entry.

cat ~/.ssh/id_rsa.pub | ssh user@host 'cat >> ~/.ssh/authorized_keys'

Alternative for machines without ssh-copy-id

ssh <user>@<host> 'mkdir -m 700 ~/.ssh; echo ' $(< ~/.ssh/id_rsa.pub) ' >> ~/.ssh/authorized_keys ; chmod 600 ~/.ssh/authorized_keys'

Creates the .ssh directory on the remote host with proper permissions, if it doesnt exist. Appends your public key to authorized_keys, and verifies it has proper permissions. (if it didnt exist it may have been created with undesireable permissions).

*Korn shell syntax, may or may not work with bash

cat ~/.ssh/id_rsa.pub | ssh tester@10.2.6.10 "mkdir -p ~/.ssh; cat >> ~/.ssh/authorized_keys; chmod 600 ~/.ssh/authorized_keys"

chmod authorized_keys so you don't get "Authentication refused: bad ownership or modes for file /home/user/.ssh/authorized_keys"

Know a better way?
