Allowing only certain users to ssh

[scruffy]

I suspect capitalization is important - denyusers is not the same as DenyUsers

[pedz]

The source code has "denyusers" in all lower case so my *guess* is that there is a conversion to all lowercase before the compare.

I've tried all the suggestions, allowusers with the usernames I would like to allow, and denyusers with just his. I've tried upper and lower case, but I can still ssh with that account. Is the format: "AllowUsers username1 username2" or am I missing something?

This did it for me, however it kills FTP, even though I did the second half of the instructions about adding /usr/bin/false to shells...

This is a very good thread!

Someone should clean it up and make it a HOWTO thread...
