I have a Ubuntu 8.04 desktop running at a remote location.
It is directly connected to an ADSL modem.
I have sudo access to this system.
I am able to access via ssh/scp too.
Now I want to limit ONLY the ssh/scp access to a few ip addresses.
In other words, keep everything else as-is ...
http, ftp, ... accessible by anyone
scp/scp ... accessible by 3 specific ip addresses only
How can I do this?
