Agree completely. But the way I explain it to beginners is that rootkit
hunters are trying to prove a negative. If I get a blank look, my second
attempt is to tell them that absence of proof is not proof of absence. I
want something that's short and snappy, as people seem to remember it
better. New people are already floundering around trying to remember
massive amounts of new information, and I don't want to leave them
completely leaning on a tool that's really only somewhat trustworthy.
One other thing I do whenever it's practical is to modify
AllowUsers space delimited list
and maybe use:
AllowGroups space delimited list
I suspect you didn't want to give a vi lesson via Usenet, or you'd have
covered the sshd tweak and restart. I *know* you know this stuff.
Now that I think about it, vi lesson via email really wouldn't be too hard.
I've done it over the phone often enough. If the OP emails me the need,
I'll attempt it. And save the file, if it's successful.
