Socket programming

  Asked By: Lorraine    Date: Mar 02    Category: Java    Views: 5672

My 3rver creates a UDP socket and 3nds it's messeges to a multicast
UDP group & port which clients R joined to.It functions correctly on
all PC's except my boss(!!!!!), which has several IP on it.I made
some check points and trace it. I realized his PC sends packet but
can not receive packet. I think the port which UDP Socket is binded
to, can not recieve packets.

That was the story (kal'ali! ;)) ), is any one who has experienced
something like this?

Is der any function which could check the UDP ports and recognize
whether they R alive :)) or not?

Can Ds problem be solved by software ?or iz it basically concerned
with network hardware?

Im not so sure if it is the case but you may want to look into binding the port  to one of the IP addresses at a time.
