IP Status (Public IP, LAN IP, WAN IP, SSID Name)

Posted in System by realityloop 237 days ago

This uses a shell script to list your public facing IP addresses, as well as en0 (ethernet) and en1 (AirPort). For AirPort, if the system is connected to a network, it will also list the SSID.

The needed shell script is here:

#!/usr/bin/perl
# a little script to get your network status

$en0_info = `ifconfig en0 | grep "inet" | grep -v 127.0.0.1`;
$en1_info = `ifconfig en1 | grep "inet" | grep -v 127.0.0.1`;
$ext_info = `curl --silent http://checkip.dyndns.org | awk '{printf $6}' | cut -f 1 -d "<" | tr -d 'n'`;
$airport_network = `/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport -I | awk -F: '/ SSID/ {print $2}'`;

if($ext_info)
{
$output .= "External: $ext_info ";
}
else
{ $output .= "External: OFFLINE ";}

if($en0_info)
{
$en0_info =~ /inet (.*) netmask/s;
$output .= "Ethernet: $1 ";
}
else
{ $output .= "Ethernet: INACTIVE ";}

if($en1_info)
{
$en1_info =~ /inet (.*) netmask/s;
$en1_info = $1;
$output .= "Airport: $en1_info SSID: $airport_network ";
}
else
{ $output .= "Airport: INACTIVE ";}

print "$output";
