NAME

Linux::Proc::Net::UDP - Parser for Linux /proc/net/udp and /proc/net/udp6

SYNOPSIS

use Linux::Proc::Net::UDP;
my $table = Linux::Proc::Net::UDP->read;

for my $entry (@$table) {
  printf("%s:%d (%d)\n",
         $entry->local_address, $entry->local_port,
         $entry->st );
}

DESCRIPTION

This module can read and parse the information available from /proc/net/udp in Linux systems.

API

The table object

$table = Linux::Proc::Net::UDP->read

$table = Linux::Proc::Net::UDP->read(%opts)

reads /proc/net/udp and /proc/net/udp6 and returns an object representing a table of the connections.

Individual entries in the table can be accessed just dereferencing the returned object. For instance:

for my $entry (@$table) {
  # do something with $entry
}

The table entries are of class Linux::Proc::Net::UDP::Entry described below.

This method accepts the following optional arguments:

ip4 => 0

disables parsing of the file /proc/net/udp containing information for open UDP ports on IPv4

ip6 => 0

disables parsing of the file /proc/net/udp6 containing information for open UDP ports on IPv6

mnt => $procfs_mount_point

overrides the default mount point for the procfs at /proc.

The entry object

The entries in the table are of class Linux::Proc::Net::UDP::Entry and implement the following read only accessors:

sl local_address local_port rem_address rem_port st tx_queue
rx_queue timer tm_when retrnsmt uid timeout inode reference_count
memory_address drops ip4 ip6
