I am new using Linux, so I would really appreciate a simple as possible answer.
I cannot ping between two computers, neither to nor from. I can ssh from one computer to another, but not the other way around.
I would be very grateful if I can get some direction as to what I might have to do in order to fix this.
The computer to which I cannot connect is Ubuntu 10.4 with wireless Internet (but I can connect to other from it), while the other one is a Mac OS.
Thanks a lot in advance.

or172.16.
or10.
alone (they're private addresses).
