Hi,
I am trying to control mpv player using unix sockets but it looks like

If I sent the string using system commands:

Perhaps your troubles aren't code and are instead network stability.
If your network isn't stable enough to receive the packets then there
isn't much you can do within software to fix it.
Unless you need socket-level access consider using a higher-level

The connection timeout doesn't work, the receive timeout (SO_RCVTIMEO)
and send timeout (SO_SNDTIMEO) does work.
Is there any way to recover from this?

Hello all!
I'm creating some sockets to a remote server and from time to time, the
sockets get "frozen".
I'm creating the socket as:
$socket = IO::Socket::INET->new (
from the remote client,.
How can I accomplish that the server still
responds to incoming requests on port 1234 but
also sends its commands over the other socket to
port 4321?
You have basically three options for reading and
writing from/to multiple sockets simultaneously:

I've found some people talking about IO::Socket:Select but I'm unable to find a

All I want to accomplish is talking over 2 (or more) sockets without the server

$addr = pack($template,AF_INET,$port,$iaddr);

on the client end (win2k - i386) it fails.

$template = 'S n C4 x8';
$port = 6668;
$proto = getprotoby
Bingo! Thanks Paul, you are correct. $_ is not getting loaded in the while

The problem is if a socket is in a TIME_WAIT state it's no longer open by
