Snort signatures update issue?

mevans336

I am also getting this error all of a sudden today.

Warning: file_get_contents(http://www.snort.org/pub-bin/downloads.cgi): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /usr/local/www/snort_download_rules.php on line 98
You last updated the ruleset: 2008-04-02
Your snort rulesets are up to date.

It also looks like it borks snort. I can't get both process to run now.

$ ps aux | grep snort
root 82228 0.0 0.0 1292 908 ?? Is 1:56PM 0:00.00 snort2c -w /var/

Hrm, I was able to get Snort to run by changing the startup mode to mwm from lowmem. Strange.

I can say that snort is working. I enabled the nmap xmas filter, and asked a friend to nmap my WAN ip address, and got him in the snort logs:

[ ** ] [ 1:1228:8 ] SCAN nmap XMAS [ ** ]

[ Xref => http://www.whitehats.com/info/IDS30 ]

I have snort running, not snort2c:

ps aux | grep snort

root 64949 0.0 24.8 66776 30332 ?? Ss 10:00AM 1:58.47 snort -c /usr/local/etc/snort/snort.conf -l /var/log/

And in the status->services page, snort shows as up and running (lowmem mode). Still I wonder if I have updated the signatures or not, but well. It works.

Mine is also working now, as I'm getting lots of SQL scans. When I switched to mwm, I was able to get both processes back:

$ ps aux | grep snort
root 11135 0.0 3.4 111568 107884 ?? Ss 3:20PM 0:20.26 snort -c /usr/lo
root 11138 0.0 0.0 1292 940 ?? Is 3:20PM 0:00.01 snort2c -w /var/

Hopefully this is just a temporary issue. Is there any way to tell what ruleset we're using?

I have got the same problem.
Warning: file_get_contents(http://www.snort.org/pub-bin/downloads.cgi): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /usr/local/www/snort_download_rules.php on line 98
How to fix it?

I've got the same thing :(

I'm running 1.2. It just started this week. At least that is the first time I noticed it.

Dear all,

I changed the performance to mwm, ran: ps aux | grep snort. I got only one process of snort running:

ps aux | grep snort

root 22778 0.0 0.1 1292 908 ?? Is 9:06AM 0:00.00 snort2c -w /var/
root 25496 0.0 0.1 1552 656 p0 R+ 9:14AM 0:00.00 grep snort

Then I did ssh to the box and ran snort manually like this:

snort -c /usr/local/etc/snort/snort.conf -l /var/log/

I got the following:
…...........
..............
+++++++++++++++++++++++++++++++++++++++++++++++++++
Initializing rule chains...
ERROR: /usr/local/etc/snort/rules/ddos.rules(25) => Invalid port: [31335,35555]
Fatal Error, Quitting..

After I edited by disabling the problematic ddos.rules(25) using web console then run the following command:

snort -c /usr/local/etc/snort/snort.conf -l /var/log/

Then I ran ps aux | grep snort again:
Now I got both of snort processes running

ps aux | grep snort

root 29629 0.0 0.1 1292 908 ?? Is 9:26AM 0:00.00 snort2c -w /var/
root 29786 0.0 14.5 151584 147892 p0 S 9:27AM 0:04.94 snort -c /usr/lo

I ran nmap using -sS switch but I did not get any alerts. Moreover, everything I want to update the snort I got this error:
Warning: file_get_contents(http://www.snort.org/pub-bin/downloads.cgi): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /usr/local/www/snort_download_rules.php on line 98
You last updated the ruleset: 2008-04-13
Your snort rulesets are up to date.

I have two questions

1. Does the snort in pfsense have to be started manually from the console? Or perhaps, I missed something.
2. Is the error regarding the update rule normal means we can ignore it?

Thanks, any response will be much appreciated.

I think I got it solved by restarting the machine, after reboot the snort runs good.
Just wondering if there's another way than reboot to solve this.

I've got the same same error on the update tab and the ddos rules. Fresh 1.2 install.

sullrich

Looks like they changed the download location?

What is the new location if you visit their website? They used to tell the location.

Juve

http://www.snort.org/pub-bin/oinkmaster.cgi/[OINKCODE]/filename

The rules still downloads. The thing not working is the page giving updates information.

Snort still not working properly after update.

" Warning: file_get_contents(http://www.snort.org/pub-bin/oinkmaster.cgi): failed to open stream: HTTP request failed! HTTP/1.1 403 You must be a registered user with a valid oink code to download this file. in /usr/local/www/snort_download_rules.php on line 98 ".

Any further ideas on how to fix this?

dalybrian

Re-installed SNORT ( currently 2.7.0.1_4 ) & changed the code on line 98 ( to http://www.snort.org/pub-bin/oinkmaster.cgi from http://www.snort.org/pub-bin/download.cgi ) and currently getting:

" Warning: file_get_contents(http://www.snort.org/pub-bin/oinkmaster.cgi): failed to open stream: HTTP request failed! HTTP/1.1 403 You must be a registered user with a valid oink code to download this file. in /usr/local/www/snort_download_rules.php on line 98 "

I even got a new Oink Code & still getting the same Error. Is there any information on the SNORT website on this issue?

kerim

Same goes to me. after i update snort package, i try to update snort rules, waiting for about 20 minutes+- to finished,then this message came out:

Warning: file_get_contents(http://www.snort.org/pub-bin/downloads.cgi): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /usr/local/www/snort_download_rules.php on line 98 You last updated the ruleset: 2008-04-29

Your snort rulesets are up to date.

Ok,,

This is not a snort or pfsense problem. This is a PHP issue, exactly with file_get_contents function, line 98 in /usr/local/www/snort_download_rules.php
–> $text = file_get_contents("$URL_SNORT");

I trying with a temporally "solution" using curl instead file_get_contents.

I have this on my script:

from /usr/local/www/snort_download_rules.php:

               sleep(1);
                $URL_SNORT="http://www.snort.org/pub-bin/downloads.cgi";

                $ch = curl_init();
                curl_setopt($ch, CURLOPT_HEADER, 0);
                curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
                curl_setopt($ch, CURLOPT_URL, $URL_SNORT);
                $text = curl_exec($ch);

                //$text = file_get_contents("$URL_SNORT",NULL);
                echo "

Any update on this issue?

f.spierings

The issue lies in the fact that file_get_contents() does not send a user agent (or empty string), in this case.
I believe you are able to set the user agent in two ways:

Specify the user agent in the php.ini (not checked)
Specify the user agent in the script (checked - working)

An example would be (around line 98 /usr/local/www/snort_download_rules.php):

ini_set('user_agent','snort download script');
$text=file_get_contents("http://www.snort.org/pub-bin/downloads.cgi");

So can i get a confirmation on what is working of the scripts, or reinstallation? I have 1.2 Release with Snort installed a week ago.
