Ubuntu Security :: Snort Not Starting - ERROR: "/etc/snort/rules/exploit.rules(264) => 'fast_pattern' Does Not Take An Argument"

May 12, 2011

I need assistance with my Snort Installation. I used Bodhi Zazen's Network Intrusion Detection System post and found it easier than the previous time I had done it. I am currently running Ubuntu 10.04 server and Snort 2.8.6.1 with BASE 1.4.5. I followed Bodhi Zazen's instructions and when I tested snort it ended with a Fatal Error due to ERROR: /etc/snort/rules/exploit.rules(264) => 'fast_pattern' does not take an argument
Fatal Error, Quitting.. Here is the entire output once I ran the test command: snort -c /etc/snort/snort.con -T Running in Test mode

Ubuntu Security :: Install And Run Snort On A Single Laptop With A Wireless Router?

Mar 25, 2010

I was wondering whether or not it is possible/advisable to install and run Snort on a single laptop with a wireless router (firewall enabled)? Does Snort require root privileges and are there any other issues one needs to be aware of when installing and running software like this?

Ubuntu Security :: Snort: Convert From IDS To IPS

Feb 4, 2011

I am currently running snort as an IDS on the same machine that acts as our gateway. I installed it using sudo apt-get install snort. However, I'd like to make it run as an IPS. Is it possible to convert that currently running snort instance from running as an IDS to an IPS without having to download the snort tar balls and install it? I do not want the tar balls because during updates and upgrades, I'd like the whole OS and installed apps (such as snort) to be upgraded.

Debian :: Better Way To Set Up SNORT IDS?

Oct 31, 2010

I am running Debian 5 and I'm trying to install and configure SNORT. My first stop is to Snort.org where I check out the directions. They tell me I need Libpcap, PCRE, Libnet and Barnyard. I've looked at the Debian Snort installation guide, and I've noticed that most the documents are really old...

I've actually got libpcap and PCRE installed and now I'm trying to figure out how to get libnet installed. It seems more tricky. I think it's the oldest api I've seen.

I guess my main area of question is if there is a better way of getting Snort up and running... I had a previous version of Linux where I install just Snort and I had network packets streaming across the screen, but that's not very helpful as I need some kind of interface so I know what the hell im looking at.

So should I follow the instructions on Snort.org as well as the "Debian, Snort, Barnyard, BASE, & Oinkmaster Setup Guide"? Or does anyone know a more up-to-date guide for Debian users?

Ubuntu Security :: No Alert Found In Result From Snort

Mar 3, 2010

I have installed snort + mysql + acid base, I add some rules into /etc/snort/rules/local.rules to test the alert:

alert icmp 192.168.1.20 any -> 192.16.1.21 any (flags:A;ack:0;msg:"NMap icmp ping")
alert icmp 192.168.1.20 any -> 192.16.1.21 any (content:"abcdefgh";;msg:"ping de windows")
alert icmp 192.168.1.20 any <> 192.16.1.21 any (flags: S; msg: "HOULA SYN Packet!"

After I restart snort and I tied 2 pc by cross cable (192.168.1.20 for windows and the victim is 192.168.1.21 for Linux where the snort is installed), my HOME_NET 192.168.1.21 and the EXTEREL_NET !$HOME_NET. The problem is when I run:
snort -dvi eth0 -c /etc/snort/snort.conf

I see the packet transmitted and received (the received conten "abcdefgh" ), when I stopped snort CTRL+C I don't found any alert in the result!!! Run time prior to being shutdown was 218.523030 seconds.

Security :: Snort And MS Threat Protection Manager?

Feb 24, 2011

I work in a relatively small organisation of about 30 people (but with a complex network) and we've been looking to move our firewall to Microsoft's Threat Protection Manager on a mostly Windows network. I've been thinking we should have an IDS/IPS inside the firewall and I've been thinking about Snort in NIDS mode but have some basic questions:

1. Can anyone recommend a good web GUI for Snort?

2. Is it advisable to run both on the same machine? (Both from a POV of security and resources.)

3. Would Snort add any real benifit to using TPM?

Programming :: Text Manipulation With Bash For Snort Alert

Nov 26, 2010

I have a little problem about string in Snort alerting. I understood about Snort alerting saved in /var/log/snort/alert and Snort will add a new entry if there was a attack from anywhere. Then here's my problem. Because it has a lot of file on it, all I want to do is parse that string in snort alert then make into simply log files with it. I'm getting confused with Snort alert and parse that file.

Here's the simple algorithm; Snort get the alert <- parse the alert with my parameter which I've configured with bash (ip address, dest, kind of attack and time) <- then sent that parse alert into new text (let's called snortsent.txt) <- after ten alerts then clear the text then waiting again until the Snort alert go on -> back to snort alert. Here's the sample of my snort alert: (/var/log/snort/alert)

Security :: Make Use Of Snort And Its Packet Filtering/inspection Abilities

Jul 26, 2010

I'm looking to possibly need to make use of snort and its packet filtering/inspection abilities to help cover for PCI. I've searched Amazon, but nothing really stand out, there is a new one (2007 - Snort Intrusion Detection and Prevention Toolkit), or slightly older ones... Managing Security with Snort & IDS Tools - 2004, Snort Cookbook - 2005, Snort for Dummies - 2004.

Now i'm tempted in just going for the latest one, but i'm completely new to snort so perhaps it needs another book like snort for dummies to get started ;-P

Ubuntu Networking :: Wireless Install Won't In Persistent USB Install?

Dec 21, 2010

I'm trying to use a persistent install of Lubuntu 10.10 on a USB flash drive. I thought it was working at first, but the wireless connection won't happen at all; period!

Whenever I click on the network Icon, all I get is a pop up message telling me I'm not connected to the wireless Then when I click on the wireless menu to select a network, the sign in window closes before I can even try to do anything with it, and then I get that "your not connected" pop up message again.

It's quite irritating. It basically won't let me sign on to a wireless Internet connection at all.Every time I do try to connect all I get is the "your not connected" message and nothing else. I'm using a 16 GB Kingston Data Traveler USB flash drive and am trying to run it on a Toshiba A100 Satellite laptop.

I've also been experimenting with a 16 GB Kingston Data Traveler 102 USB flash drive, with Linux Mint 9 LXDE installed on it and haven't had any problems with that one accessing wireless connections on the same computer.

Does anyone know what would cause this? It seems to boot well enough. But I just can't get Lubuntu 10.10 to access wireless networks to save my life. Could it be a hardware issue? I should note too that I used exactly the same USB flash drive on the same computer when giving Xubuntu 10.10 a "test drive" as a persistent install. But I didn't have any troubles like that with it.

Ubuntu Networking :: No Networking On Fresh Install?

I accidentally downloaded a torrent of the ALTERNATIVE ubuntu 10 installer. install went fine except for the part where i had to do the networking part, think i did something wrong there (as in skipped it). past ubuntu installs worked perfect using regular installer. googleing led me to use "lshw", and the command lshw says that the network is disabled (shows correct network controller tho).

CentOS 5 Networking :: Install The Latest Kmod-r8168 Rpm - It Failed To Enable The Networking Support

Dec 30, 2010

I had the elrepo kmod-r8168 driver running smooth for a while on my development box.
Yesterday, I did a clean install on it and when I tried to install the latest kmod-r8168 rpm, it failed to enable the networking support:

# yum --enablerepo=elrepo install kmod-r8168

The install performed all proper steps to disable the 8169 driver, I double checked to be sure.This is not a connectivity issue. If I remove the kmod-r8168 rpm, reboot the server and run the ifconfig eth0 up to activate the interface, everything works as expected. I use the latest kernel (2.6.18-194.26.1.el5 x86_64).

First, I performed a clean install, activated the eth0 and did a yum update, then installed the kmod-r8168 with yum. Then, I reinstalled the OS again, activated the eth0 and installed the kmod-r8168 on a 5.5 CD based kernel, same fail results. The only hiccup is: every time I start the box, I have to activate the eth0 interface (with default CentOS 8169 driver):

# ifconfig eth0 192.168.1.3
# ping -c 3 192.168.1.1 (no packets lost)
# ifconfig eth0 up

Once I do this, I have network connectivity.
