Re: GNU Parallel Bug Reports Unable to transfer multiple files when password-less SSH is not setup

I assume there is a reason why you do not use authorized_keys and ssh-agent.

Would sshpass solve your problem:

You ought to be able to use this is sshlogin:

parallel -S "/usr/bin/sshpass -p mypass ssh address@hidden" echo ::: foo
