Trace DNS Script

[express]

Having problems with script found here only parts of it do not work.
Get these 2 errors. Any help would be appreciated.

[Mark Hensler]

It works with my IP, but not my domain name.

[George L]

i use the same script.. what you need to do is download the latest version which fixes a problem with 4.1.2

[express]

Yes same here, trying to figure out is wrong on domain name end.

[George L]

network query tool 1.2

http://shat.net/php/nqt/

3/1/2002: PHP 4.12 changed the behavior of the gethostbyaddr() function, which broke some parts of the script. Everything should be fixed now ...

[express]

Will try it Eva, Thanks Much

[express]

Ok all works except these 2, Eva do you have a problem with these also?

Oh boy, a new toy!

[Mark Hensler]

hacked it a little...

I've never used `dig` before (I actually had to install it just now).
I hope I didn't remove anything vital.
I just tried to remove the DiG headers and commented lines like noted in his TODO.

function dig($target){
    global $ntarget;
    message("<p><b>DNS Query Results:</b><blockquote>");
    #$target = gethostbyaddr($target);
    #if (! eregi("[a-zA-Z]", ($target = gethostbyaddr($target))) )
    if( (!eregi("[a-zA-Z]", $target) && (!eregi("[a-zA-Z]", $ntarget))))
    $msg .= "Can't do a DNS query without a hostname.";
    else{
        if(!eregi("[a-zA-Z]", $target)) $target = $ntarget;
        //  if (! $msg .= trim(nl2br(`dig any '$target'`))) #bugfix
        if (! $msg .= '<pre>' . `dig any '$target' | awk '{if (NR>6) print $0}' | sed -e 's/^;; //g' -e 's/^;//g'` . '</pre>') #bugfix
        $msg .= "The <i>dig</i> command is not working on your system.";
    }
    echo $msg; $msg=NULL;
    #TODO: Clean up output, remove ;;'s and DiG headers
    $msg .= "</blockquote></p>";
    message($msg);
}

Thanks that worked great, Here is what I have left
Ping Results:

Ping failed. Host may not be active.

Traceroute Results:

Traceroute failed. Host may not be active.

By the way from shell traceroute works
here is how it looks in a shell output

[email protected] [~]# /usr/sbin/traceroute realwebhost.net
traceroute to realwebhost.net (64.71.176.104), 30 hops max, 38 byte packets
1 64.71.176.104 (64.71.176.104) 1.054 ms 1.084 ms 0.886 ms

[express]

We have it working we had to chmod 4755 /usr/sbin/traceroute
We removed the traceroute part though from script because it took way to long on some ip's and domain names, We left ping though.

[Mark Hensler]

I've noticed that about traceroute too.

Does your ping work? (mine is)

[express]

Yes ping works ok.
