Try changing this to:
127.0.0.1 127.0.0.1 255.255.255.0 lo
192.168.81.38 192.168.81.38 255.255.255.0 eth0
This says send 127.0.0.1/24 to 127.0.0.1 on interface lo
send 192.169.82.38/24 to 192.168.81.38 on interface eth0
You won't need default until you have a gateway to the internet.

Give it a try, and good luck!
