Warn Webmaster

[Anon]

As it's very important that the website I'm building doesn't crash, I would like to implement, next to the different backup systems, a warning systems which calls for the webmaster if priority is very high.

I can send (and do send) a simple mail, but this would not satisfy all my needs.

Does anybody know of a public server which allows automated SMS-messages to be send? Automated as in "you don't need to surf by the website" or as in "you can circumvent having to surf by the website".

Or any other type of pager-like messages?

Pagenet pagers, and I'm sure most other companies, provide SMTP forwarding for free as part of their basic text pager service.

I have a couple of different scripts that call me if things go wrong on a server, they just email it to my pagenet pager's email address.

ICQ has a facility where you can send a short message to an address and it will appear very quickly on the appropriate ICQ app.

Check ICQ.com, or there is also some ICQ-related code at http://www.zend.com

OK, I'll post it here, and maybe in the code repository, if I can get it to work.

Here's my super simple little admin script that's super easy to configure for each new machine you need it to check. I'm sure someone could abstract it to run off a text file or database or something.

#!/usr/local/bin/php -q
<?
$ADMIN="[e-mail]";
$PIN="somenumber";
$ADMIN_EMAIL="8007208398.$[e-mail]"; # This is for pagenet nationwide
$TMP="/tmp/wget.test";
$PATH="127.0.0.1/";
$tmp=split("/",$PATH);
$SERVER=$tmp[0];
$FILE=$tmp[1];
$USER="";
$PASS="";

if ($USER||PASS) $URL = "http://$USER:$PASS@$PATH";
else $URL = "http://$PATH";
$return=system("wget -q -s -t 2 -T 60 -O $TMP $URL");
$fp=fopen($TMP,"r");
$body=fread($fp,filesize($TMP));
fclose ($fp);
unlink ($TMP);
$test=split(" ",$body);
if ($test[1] == "200"){

Uncomment for a positive report message in cron mail

print "Hostname $SERVER is working working!\n";

}else{
$TMP="/tmp/sm.test";
$fp=fopen($TMP,"w");
$SENDMAIL = "From: $ADMIN\n";
$SENDMAIL.= "To: $ADMIN_EMAIL\n";
$SENDMAIL.= "Subject: Server down\n\n";
$SENDMAIL.= "The webserver known as $SERVER has stopped responding to http ";
$SENDMAIL.= "get requests for file $FILE\n\n";
$SENDMAIL.=".";
fwrite($fp,$SENDMAIL);
fclose ($fp);

Uncomment for a negative entry in your cron job mail

print $SENDMAIL;

system ("/usr/lib/sendmail -oi -t -odq <$TMP");

unlink ($TMP);
}
?>

Note that due to some strange issues at work the default sendmail mail() interface doesn't work right, so I've used sendmail. replacing this with send() is mostly chainsaw work.
