rsync with non standard ssh port

If your destination ssh daemon on the remote server runs on a non-standard port, and all the port related options to rsync only change settings if you’re running the rsync-daemon. Here is a solution to use rsync simply by specifying a different port

just Pass the port parameter to ssh with the -e option:

# rsync -avz -e "ssh -p $portNumber" user@remoteip:/path/to/files/ /local/path/

Copy your ssh public key to a server from a machine that doesn't have ssh-copy-id

first generate the keypair

ssh-keygen

then

cat ~/.ssh/id_rsa.pub | ssh user@remotemachine "cat >> ~/.ssh/authorized_keys"
