Hi there...
I'm pretty happy with my mandrake systems here since switching over from
RedHat (their 8.0 is a piece of...)
However now I'm stuck:

I installed a new server, switched the security level to "paranoid" since it
will have a direct link the the world. Actually it is very paranoid...
Everything is fine, iptables working fine, sshd running, client running.
But whatever I do there is no way to login via ssh from wherever.

I added a "+:wheel:<name>" entry to /etc/security/access.conf (it's the only
option and the connecting user is in the wheel group) and tripple checked
the /etc/ssh/... settings. All files are read, sshd reacts on changes.
/var/log/messages reveals a "connection refused from...".

Bummer

I do have the impression that the "paranoid" setting prevents ALL connection
attempts at all (wherever, however). But that does not really make sense,
does it? After all you have to have one way to login...

Any ideas all the gurus?

Thanx,
Christian
