Database Server

server0002 .......................... DOWN Shocked

server0005 ......................... UP Very Happy

server0019 .......................... UP Very Happy

if anyone knows of any other database servers at f2s let me know so I can include them, too.

hmmmmmm, I know this is not related, but I'm looking for a script that can perhaps ping/ test to see if a certain server is online or not and give answers automatically, any ideas?

Here's a little ping script where you can put in the ip you're interested in testing and then you could use the script with a crontab:

<?
$ip = "www.oreillynet.com";
// ping some server five times and store output in array $output
exec("ping -c 5 $ip", $output);

// format each line of output
while (list(,$val) = each($output)) :
print "<pre>$val</pre>";
endwhile;
?>

Found this little gem sometime ago from the O'Reilly ONLAMP site.

But, if you want something a little better, check out the "Ping-It" script at hotscripts:

http://www.hotscripts.com/PHP/Scripts_and_Programs/Networking_Tools/Ping/

The interface on "Ping-It" is nice and the results are intelligible.

BTW, make sure you have a server that has the ping utility available. f2s apparently doesn't make ping available to users! Sad

I think it's more a question of whether PHP is running in safe mode. PHP won't let you run that kind of command in safe mode, that's probably why it doesn't work at F2S.

Hence why I don't use F2S or Cyberwings.......

I just found out that Cyberwings' servers are no longer running safe mode...

Plesk 12 was last time I checked, that server is what nightmares are made of, an average of 55% uptime over the past 2 weeks, thats even worse than server39 was on f2s........

Cyberwings turn safe mode off if you ask them too...

Edit just read Daniels post and so it seems they no longer run in safe mode at all...

Okay, after putting together Daniel's observation with what a buddy of mine told me about ping, I was able to get ping to work at f2s a few minutes ago. Woo-hoo! Smile

Here's the script I used:

#!/usr/bin/php

<?
// ping some server five times and store output in array $output
exec("ping -c 5 server0002.freedom2surf.net", $output);

// format each line of output
while (list(,$val) = each($output)) :
print "<pre>$val</pre>";
endwhile;
?>

~~~~~~~~~~~~~~~~~~~~~~~~~~~

Note: the #!/usr/bin/php is required for a command of this type b/c as Daniel so rightly noted PHP runs in safe-mode @ f2s. This command basically says use the php binary rather than the server module.

If you try ping without the -c in a script, the script may just hang. The -c paremeter (shorthand for count) basically says "Stop after sending (and receiving) count ECHO_RESPONSE packets."

And, for you newbies who may be wondering what the pre tags are doing in this code, they help to make the output more readable b/c without them it might be diffcult to easily view the resulting output.

And, the resulting output looked, unsurprisingly, like this today: Sad

PING server0002.freedom2surf.net (194.106.33.37): 56 data bytes

--- server0002.freedom2surf.net ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss

~~~~~~~~~~~~~~~~~

If you are interested in more of the details about ping, here's a really good url:

And, here's where I found a working php ping script and they have other networking scripts, too:

Note that if you are on a Windows server, you use -n instead of -c. This is system call, so if you are moving your scripts, PHP cannot fix it for you.
