Hello,
First I'd like to say what a pleasure it always is
browsing your forums. 
After installing a fresh Sentinel 2.30 on a Nuke 7.7
web with 3.0 patches, I received a white page (on the main
page- index) with Firefox 1.04, Netscape 7.2, & Opera. All but
IE (for once  ). Hitting the "refresh" button loads the page and all is fine.
I checked my server logs and saw this warning:
PHP Warning: ob_start(): output handler 'ob_gzhandler' cannot be used after 'URL-Rewriter' in /home/mysite/public_html/mainfile.php on line 54
The site was fine until installing Sentinel 2.30.
I did see a similar post Only registered users can see links on this board! Get registered or login!
and changing the 3.0 patched code from:
Code:ob_start(array('ob_gzhandler',5));
ob_implicit_flush(0);
header('Content-Encoding: gzip');
|
back to the original as Chatserv suggested:
Code:ob_start();
ob_implicit_flush(0);
//header('Content-Encoding: gzip');
|
Fixed it.
Hope this helps someone that adds Sentinel after the patch.
My server specs
Linux - apache 1.3.33
php 4.3.11 |

You might also try moving this codeCode:if (defined('FORUM_ADMIN')) {
@include_once("../../../includes/nukesentinel.php");
} elseif (defined('INSIDE_MOD')) {
@include_once("../../includes/nukesentinel.php");
} else {
@include_once("includes/nukesentinel.php");
}

afterCode:$phpver = phpversion();
if ($phpver < '4.1.0') {
$_GET = $HTTP_GET_VARS;
$_POST = $HTTP_POST_VARS;
$_SERVER = $HTTP_SERVER_VARS;
}
if ($phpver >= '4.0.4pl1' && strstr($_SERVER["HTTP_USER_AGENT"],'compatible')) {
if (extension_loaded('zlib')) {
ob_end_clean();
ob_start('ob_gzhandler');
}
} else if ($phpver > '4.0') {
if (strstr($HTTP_SERVER_VARS['HTTP_ACCEPT_ENCODING'], 'gzip')) {
if (extension_loaded('zlib')) {
$do_gzip_compress = TRUE;
ob_start(array('ob_gzhandler',5));
ob_implicit_flush(0);
header('Content-Encoding: gzip');
}
}
}
$phpver = explode(".", $phpver);
$phpver = "$phpver[0]$phpver[1]";
if ($phpver >= 41) {
$PHP_SELF = $_SERVER['PHP_SELF'];
}

in mainfile.php. Let me know if that works and I will add this to the NukeSentinel FAQ. |

Raven, this fixed my problem:
Mac users using Solaris also had a problem, their problem is gone too! The error they were getting is: nsurl-error domain 1011.
Thanks! |

Oh wait! Hey Raven or Bob, now that I have made these changes. I no longer get a blocked page notification when I conduct a union attack.
Help please? |

Please post your first 100 lines or so of mainfile.php. That should not stop Sentinel. |

I made the changes as recommended by Dove and it works now. Possibly less secure I'm sure. Here is my current mainfile.php
Code:
<?php
if (defined('FORUM_ADMIN')) {
@include_once("../../../includes/nukesentinel.php");
} elseif (defined('INSIDE_MOD')) {
@include_once("../../includes/nukesentinel.php");
} else {
@include_once("includes/nukesentinel.php");
}
if (!ini_get("register_globals")) {
import_request_variables('GPC');
}

Change it back as I instructed. Then remove this codeCode://Union Tap
//Copyright Zhen-Xjell 2004 http://nukecops.com
//Beta 3 Code to prevent UNION SQL Injections
unset($matches);
unset($loc);
if (preg_match("/([OdWo5NIbpuU4V2iJT0n]{5}) /", rawurldecode($loc=$_SERVER["QUERY_STRING"]), $matches)) {
die();
}
$queryString = strtolower($_SERVER['QUERY_STRING']);
if (stripos_clone($queryString,'%20union%20') OR stripos_clone($queryString,'/*') OR stripos_clone($queryString,'*/union/*') OR stripos_clone($queryString,'c2nyaxb0')) {
header("Location: index.php");
die();
}

That's in the installation instructions, btw. That's what's blocking NukeSentinel. You don't need it. |

Hi Raven and thank you for you patience and kindness,
Everything works fine now.
In your instructions at section 4, you start talking about Upgrading. This lead me to think that everything else was about upgrading, which it obviously was not. So I ignored that part.
I apologize for not understanding.
Thanks, everything is gold. |

This did the trick for me too, although the codeing was a little different for some reason in my mainfile, I just added it after the:
Code: $PHP_SELF = $_SERVER['PHP_SELF'];
}
|
and it's worked fine with no more errors!
Thanks Raven!! |

I moved
Code:if (defined('FORUM_ADMIN')) {
@include_once("../../../includes/nukesentinel.php");
} elseif (defined('INSIDE_MOD')) {
@include_once("../../includes/nukesentinel.php");
} else {
@include_once("includes/nukesentinel.php");
}
|
as instructed and it solved the problem for me as well (just in case you're still wondering if it's FAQ material).
Thanks for the tip (I don't count how many times this forum helped me). |

Well I have read this thread and others but cannot get the site back up. Fresh install of 7.6 v3.0b with NukeSentinel_71-78_232. Restored the original edited files but it is still blank.
I run the old analyze.php and I have a good connection.
This is my third time installing Sentinal. You would think I would get it right.
I have yet to run the nsnst.php as I have yet to get the site up again. I uploaded all the files along with the edited filed and the site went blank before I ran the nsnst.php
I tried to clear cookies but no good. I even tried to run the nsnst.php regardless but no joy. |

Take NukeSentinel out of the picture. Drop the database and delete all the files. Then, reload the files w/o NS and recreate the database. Does the site come up? What site is it? |

I can't drop the database as it was an import of around 60 users of a PHPBB site. Everything was working perfectly until I tried to install Sentinal. Before I had a chance to run the nsnst.php I had a blank page.

What is the error log showing? Are you sure the MySQL parameters are correct? |

Well the site is back up without Sentinal. A remaining bug is now I have no messages on the front page. I had one programmed with unlimited expiration but I don't see it any more. I deleted and redid it but still nothing. Cleared cookies but again not seeing the front page message. |
