Hello Monks...

I am trying to write up a Client/Server Script using IO::Socket::INET and I continue to get strange results.

I am using a fork to allow the server to serve multiple clients.

It seemed everything was working, but now it seems to be hanging just after the fork call.

The first client connects and everything is fine. Then the second client connects, the program tries to fork and the stops. As soon as the first client disconnects then the second client continues normally.

I don't believe the problem is related to the FORK, it seems to be related to reading from the sockets.

I generally read and write to the sockets as such:
print $socket "Hi there\n";
my $msg = <$socket>;

If anyone has some experience with this please help. I've gone through examples and docs I could find on the web, but they don't seem to work very well either :)
