Replacement for gnokii SMS daemon. Based on http://xgu.ru/wiki/Gnokii but a bit tricky.

getsms.php

<?php
if ($_REQUEST["sender"] == "+7921*******" AND $_REQUEST["pass"] == "****") {
// You're free to do any actions - post to twitter, send another SMS or just write to file
// As I do for displaying this on my homepage
	$fp = fopen("/home/kolo/****/****.txt","w");
	fwrite($fp, stripslashes($_REQUEST["text"]));
	fclose($fp);
	mail("kolo@****", "SMS Alarm @ +7926****", var_export($_REQUEST, true)); // Good for debugging
}
?>

getsms.sh

#!/bin/sh

# Before asking why I use wget, but not just writing to file
# think of this running on different hosts

smsgate()
{
    sender="`gnokii --getsms SM 1 2> /dev/null | grep Sender | awk '{print $2}' 2> /dev/null`";
    [ -z "$sender" ] || {
