Good Morning List
<alert=newbie>
I have a server at home (FC-1) running Bind, Sendmail, Apache, procmail,
etc. It's my mail and webserver only. I have been getting a large
number of dictionary attacks on SSH. In excess of 500 per day. I'm
trying to tightenup my security. I started by changing SSH from
listening on port 22 to listening on port 3022. I updated both
SSH.config and SSHD.config to listen on port 3022. I also changed the
port forwarding on my router to forward port 3022 to the server's IP
address. After reloading SSHD I tried to log in to my server using
putty from inside the firewall, and I've tried to login using putty from
outside the firewall, but I cannot connect.
What am I doing wrong?
Also, I am aware that security by obfuscation is not a good way to lock
down a server, but it's just the first layer of what I hope will be a
multi-layer approach.
</alert>
Thanks for listening.
Mark
