I have a winsock app to send udp datagrams to an embedded controller. I put the
eth add of the controller in the arp table, and I put the 'dummy' ip add in a
line in the hosts file. So I create the socket and fill in the ip addr, it
should look up the eth addr in the arp table, right?
I have an entry in the hosts file with the ip address and ethernet address of
my device. When I open the socket to that ip address, the sniffer shows it
sending the packet off to the default gateway. This all worked last week till
the network guy changed everything from 192.168.1.1 thru 200 to 5.1 thru 5.99.
My device is still 192.168.1.200. I should be able to send a udp datagram to
that ip addr, and have it look up the eth addr in the host file, right? What
got messed up and how do I change it back?!? Thanks!
