Multitail over ssh

I want to use [multitail](https://www.vanheusden.com/multitail/) over ssh. But following command fails: $ multitail "ssh dev-04 tail -f /opt/app/app.log" Error opening file ssh docdev-04 tail -f /opt/alfresco/share.log (No such file or directory) However just ssh with tail works fine and displays the content of the file: $ ssh dev-04 tail -f /opt/app/app.log Enter passphrase for key '/home/username/.ssh/id_rsa': 2016-08-03 09:40:27,926 INFO [org.springframework.extensions.webscripts.DeclarativeRegistry] [localhost-startStop-1] Registered 8 Package Description Documents (+0 failed) I would guess that the problem is in the password request. But anyway I don't know how to make it work
