Everything looks pretty good. So, first, try pinging 192.168.1.22. If
you can get that box to ping then you can move onto anything
else. Now, tell us this:

(1) Is there a TX/RX light on the ethernet port on your NIC? On the
switch/hub that you are connected to?

(2) Are those lights on? Are you using the right kind of cable. Some
switches/hub will one port that requires a cross over cable, while all
the others will use normal cables and so on.

(3) Do those lights blink when you try ping from the Linux box?

(4) What does "netstat -rn" say?

(5) If you can ping the gateway, what the nearest machine after the
gateway that won't ping?

(6) Finally, run ping on the Linux box, not somewhere else.

Cheers!
