Server Implementation

To enable clients to connect to them, servers must specify:

Use the IO::Socket module:

Documented as perlipc
IPC is interprocess communication:
- Signals, fifos, pipes, safe subprocesses, sockets, and semaphores

Example of enabling clients to connect:

use IO::Socket;
$server = IO::Socket::INET->new(
Proto => 'tcp',
LocalPort => 9000,
Listen => SOMAXCONN,
Reuse => 1
);

LocalPort: Port numbers are standardized server IDs. Examples:

Listen: How many connections your server can queue before turning requests away.
- SOMAXCONN is the highest number for your system.
Reuse: When TRUE, the server can restart without waiting for cleanup from the last server on this port.
