Ping an IP and Display Results

CyberSEAL

Hi, this is my very first time here, I hope someone can help me, this is so frustrating. I'm running a php-nuke site and am trying to add a "block" to the homepage. Here is the php code I'm using for the site to do this:

<?
if (eregi("block-TestPing.php", $PHP_SELF)) {
    Header("Location: index.php");
    die();
}
$gamehost = "207.xx.xx.xxx";
$result = system("ping -c 1 $gamehost");

$content .= "<CENTER>";
$content .= "Your ping to our network is $result ms";
$content .= "</CENTER>";
?>

It displays this on my page:

Your ping to our network is ms

Just seems to ignore my $result...

🙁

system() returns only standard output, to combine std and err append
2>&1 to your cmd, eg "ls -l 2>&1"
consider using exec(), shell_exec() or passthru(), alternatively

That looks like it should work--maybe a php conf problem?

try

echo "write this ".$variable." now";

Safemode is enabled for this domain, could that be stopping anything?

Hmm, this didn't work either, it wrote "write this now" to the page. I'm new to php, what should I look at in the conf file? Thanks very much!

Sorry, first try this

$variable="write me";

echo "This should ".$variable.".";

Yes, that's the problem. See this page on php.net talking about safemode: http://www.php.net/manual/en/features.safe-mode.php . You can only execute programs in a specific directory if safemode is enabled... this directory is defined by the safe_mode_exec_dir directive.

Safemode is disabled now, still not working...

Well, progress is made, at least I'm getting a new msg:

Your ping to our network is ping: icmp open socket: Operation not permitted ms

🙂

Ok, I know this is permissions related now, I just hope I don't open any holes by loosening restrictions on using ping6. Anyone wanna give me a tip? Thanks, this board has been very helpful to this firsttimer. I'm kind of new to coding in general and from what I can tell php is a good one to start with...

Ok, I fixed it and have the ping showing up in the block on my homepage... Now if I could only format the output to the page so that only the actual time in ms is displayed. I'm currently getting this:

Your ping to our network is PING 207.xx.xx.xxx (207.xx.xx.xxx) from 216.xx.xx.xxx : 56(84) bytes of data. 64 bytes from 216.xx.xx.xxx: icmp_seq=0 ttl=62 time=561 usec --- 216.xx.xx.xxx ping statistics --- 1 packets transmitted, 1 packets received, 0% packet loss round-trip min/avg/max/mdev = 0.561/0.561/0.561/0.000 ms

Oh, and my problem was that I'm an idiot and needed to change the permissions on /bin/ping and not /sbin/ping6...

derrrrrrrrr..........

one possible solution is (if string always looks like you say):

$array = explode("/", $systemoutput);
echo $systemoutput[sizeof($systemoutput)-3] . " ms";

subtract 4 for "min", 2 for "max"

Try something like this one.

$run = 'ping' . ' -R -w 10 ' . $pingto;
system(EscapeShellCmd($run));

$pingto is the IP you want to ping.
-R Show route to $pingto first.
-w 10 limits the reply to 10 times.

Just remember to limit/clean up the $pingto variable so no one misuses it.

It wouldnt do if someone flooded someone else with it 🙂

Try looking at this page on IPV6.
http://seti.unipg.it/ipv6/IPv6-HOWTO-6.html#Cannotping
Here it says;
"ping: icmp open socket: Operation not permitted": you are not root and ping6 has SUID bit not set. ICMP sockets are only allowed to root for opening.
