Hi All,
I was wondering if there was any way to restrict server ssh, ftp
and even http access to certain countries / ip ranges? I've been
using debian for a while at home but am pretty new to the security
side of things.
Any help much appreciated
I don't see any way of configuring sshd for that so if this is
something
you need, you'll need to use a firewall. I suggest shorewall.
But lets review why you think you need this since its not a standard
requirement.
Doug.
The reason i ask is that recently a server that i was working on was
sending spam emails for some other company that i've never even heard
of. I'm just looking at ways to avoid this from happening in the
future. As i am new to server security, i'm looking for a way to
block non Australian ips while i figure out how this company came to
be sending emails from our server.
Cheers
Will
Have you checked your server to see if it is an open relay? That would
also allow anyone to send spam through your mail server. You do some
tests through here:

I've checked the relay and its closed, but i have found a script in the
tmp/ folder that looks like it may be the culprit. I still have no idea
how it got there though
