The 'No route to host' for root only looks odd. This is of course a routing message. If I try to login as root on a server where root isn't permitted to login, I get a straightforward 'Permission denied' message. Can you try nmap 192.168.0.5 -p 22 both as lisi and as root? This will test both routing and firewall rules of client and server, and the correct answer should be approximately: $ nmap 192.168.101.3 -p 22 Starting Nmap 7.12 ( https://nmap.org ) at 2016-05-31 21:09 BST Nmap scan report for server.jretrading.com (192.168.101.3) Host is up (0.00045s latency). PORT STATE SERVICE 22/tcp open ssh Nmap done: 1 IP address (1 host up) scanned in 0.04 seconds and really ought to be pretty much the same for root and non-root users, except that root is also given the MAC address of the machine. If there is another difference, and there must be, then we can go from there. With out-of-the-box Debian machines, this should all Just Work, but it may be that Ubuntu is being 'helpful'. nmap is not of course attempting to login, so the only part of the server sshd_config which is being tested is the interface and port specification. There are other configurations of both client and server which can interfere, and we hope to identify any such problems arising. But can you really not use a non-root user for ssh? I don't have root ssh access to my (no X) server, but it doesn't stop me doing things to it. -- Joe
