Frodo - my bad, I cut&paste'd the wrong contiguous sections of my original code. Earlier on I was trying to receive and send from the same socket, but when this started giving me problems I created a pair of individual receive and send ($s_receive and $s_send) respectively. I did try to implement this in a single socket initially, I just posted the updated code by accident.

Sorry for the confusion (see my UPDATED example in the original reply).

The following section was taken from an example I found online: 

print $s_socket "$match\n";
print scalar <$s_socket>;

If it's unnecessary I can take it out - it worked so I didn't mess with it. What was the original purpose behind this "scalar" anyways?

Regarding the example you provided me, I have one primary question:

If I use a single socket for two different clients, can I still distinguish between which client I am connected to? What if my Third process connects to $conn1, and my First to $conn3 just by the order in which they happen to reach the Second process?

Is it better to setup individual ports/connections/sockets for two different clients, and then use those individual ports in a bidirectional manner?

One other thing I'd like to ask: Given that these processes will likely all be on the same machine - is there a better means of IPC to use other than sockets?

Sorry again about mangled code - I've been up for awhile:)
