Topic: punbb_online table -> get_remote_address()
I'm watching my punbb_online table via phpMyAdmin and in the ident field I can find Guest's IP address (user_id = 0) that are private (not routable) IPs like 192.168.*.*
Below is the phpBB 2.0.8 code to obtain the client's IP:
if( getenv('HTTP_X_FORWARDED_FOR') != '' )
{
$client_ip = ( !empty($HTTP_SERVER_VARS['REMOTE_ADDR']) ) ? $HTTP_SERVER_VARS['REMOTE_ADDR'] : ( ( !empty($HTTP_ENV_VARS['REMOTE_ADDR']) ) ? $HTTP_ENV_VARS['REMOTE_ADDR'] : $REMOTE_ADDR );
$entries = explode(',', getenv('HTTP_X_FORWARDED_FOR'));
reset($entries);
while (list(, $entry) = each($entries))
{
$entry = trim($entry);
if ( preg_match("/^([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)/", $entry, $ip_list) )
{
$private_ip = array('/^0\./', '/^127\.0\.0\.1/', '/^192\.168\..*/', '/^172\.((1[6-9])|(2[0-9])|(3[0-1]))\..*/', '/^10\..*/', '/^224\.
.*/', '/^240\..*/');
$found_ip = preg_replace($private_ip, $client_ip, $ip_list[1]);
if ($client_ip != $found_ip)
{
$client_ip = $found_ip;
break;
}
}
}
}
else
{
$client_ip = ( !empty($HTTP_SERVER_VARS['REMOTE_ADDR']) ) ? $HTTP_SERVER_VARS['REMOTE_ADDR'] : ( ( !empty($HTTP_ENV_VARS['REMOTE_ADDR']) ) ? $HTTP_EN
V_VARS['REMOTE_ADDR'] : $REMOTE_ADDR );
}
