I completely agree that exposing SSH to the internet with password authentication, even if it is not at port 22, is a bad idea. Avoiding that is exactly what I set out to do by posting here. I feel it is a rather unfortunate choice to use SSH auth in the default configuration, at least it is in Ubuntu land (<a href="https://help.ubuntu.com/community/FreeNX">https://help.ubuntu.com/community/FreeNX</a>). I might add some notes to it :)<br>
<br>Thanks Chris, I did not opt for your solution (which is rather elegant actually) but it did put me on the right track. I opted for the PASSDB authentication method and disabled SSH. With custom keys and pw auth disabled, that's more than enough. I think SU authentication may be a bit better though.<br>
