In what .ssh/config have you set the hostname? In /home/you/.ssh/config or /root/.ssh/config? When you use sudo you run the program as root, hence it will look in the root home directory for user specific setting. Another option is to use /etc/ssh/ssh_config, which then will apply those settings to every user on the machine. Also, an Ubuntu system very much has a root user. It is simply locked. If you want to use it you can do so by giving it a password and/or an ssh public key. // Andreas
