[ee122] address family not supported by protocol family

I wrote a sender and a receiver. The sender sends then waits for receiver
from the receiver. The receiver waits for receive then send back and ack.

This is my socket call: socket(PF_INET, SOCK_DGRAM, 0)
Then I set AF_INET for my sockaddr_in as the Beej suggested.

I tested on localhost instead of ilinux3

The receiver runs on ilinux3 (the network is localhost), and a macbook, but
it doesn't run on c199. The error returned was: Address family not supported
by protocol family.

The sender runs fine.

I tried to use AF_INET for the socket() and AF_INET for sockaddr_in, the
problem is the same.

Can anyone tell me what the problem is?
