Snort on Ubuntu Linux with webmin

I want to install Snort on my ubuntu linux systems Ubuntu 6.06 LTS. I usualy do a lot of the system administration with Webmin. I will like to keep it that way. The main thing is to install snort and I am having a dificult time following the instructions that are in the manual. I wonder if someone has already make this installation in Ubuntu.  any advice, Thanks, M

yeah I tried tghios and I am still no luck. I need a guidline like some kind of check list and steps to get this to work. I need to know the webmin part mostly. I used to get this to show in webmin as a module. I has mysql setup and the acid program. M
This site looks promising -
Below is the text of the forum step by step guide to install snort on ubuntu.

I finally created a new guide for Feisty which is very similar but if anything easier.
This guide will show you how to install the IDS system snort. Have snort log to a mysql database. Then be able to access the information in that database with Base which you can access through apache. 
Most of the information from this guide I learned from Patrick Harper's Centos guide. I would recommend taking a look at it even if your installing snort on Ubuntu.
First edit /etc/apt/sources.list and Uncomment these 2 lines. (My file actually has more uncommented so I'm not sure which sources you'll actually need. If you run into problems try uncommenting more. You can always change it back when your done.)
deb breezy-updates main restricted
deb-src breezy-updates main restricted  
Next update
sudo apt-get update  
Install snort with mysql support
sudo apt-get install snort-mysql  
The ubuntu will bring up a configuration dialog and a network that you can use. I replaced this with any so it will log all traffic. Next it'll ask if you want to set snort to log to a mysql server. For now we'll say no because we haven't set mysql up yet. 
Before testing snort I'm going to go ahead and install oinkmaster and get the latest rules. Oinkmaster is a program that you can use to automatically fetch snort rules.
sudo apt-get install oinkmaster  
Now you'll need to edit the oinkmaster config file which is located /etc/oinkmaster.conf I would recommend going to and registering so you can obtain an oinkcode.
url =  
url = b9a70e2a4/snortrules-snapshot-2.3.tar.gz  
just make sure you replace 5a08f649c16a278e1012e1c84bdc8fab9a70e2a4 with your oink code. Pay attention to the version of snort your using. To find out type snort -V. My example above is version 2.3.
Now to test oinkmastser
sudo oinkmaster -o /tmp/
ls /tmp  
The -o switch is for output directory. You should see several .rules files in /tmp now.
If everything works out alright then update your snort rules
sudo oinkmaster -o /etc/snort/rules/  
A good idea is to add oinkmaster to a cron job to update your rules automaticlly. I'm a bit rusty with crons so I'm gona leave that out of this how to until I read up on them again.  
Now edit the snort config file
sudo vi /etc/snort/snort.conf  
In the begging there are a couple of variable you should check on. The default should work fine. Read over the config file, the comments provide more information about the preprocessors and other snort options.
var HOME_NET any
var RULE_PATH /etc/snort/rules  
At the very end you'll find the rules list. Here you can uncomment additional rule sets depending on what rules you want to monitor.
Nows the time to fire snort up using the snort config file.
sudo snort -c /etc/snort/snort.conf  
By default snort logs alerts to /var/log/snort/alert
To test snort I used another computer and did a scan with nmap.
sudo nmap -sS Your_IP_Address  
If you look through /var/log/snort/alert you should see some port can activity. Do a search on the file. If its empty then something is wrong.
sudo cat /var/log/snort/alert  
Now to install mysql
sudo apt-get install mysql-server  
Theres a couple of questions apt asks for and I just used the default by pressing enter a couple of times.
Edit the snort config file again so we can change where snort logs its outputs
sudo vi /etc/snort/snort.conf  
Comment out so it looks like the following. Mine was line 512.
# output log_tcpdump: tcpdump.log  
Uncomment, line 529
output database: log, mysql, user=root password=test dbname=db host=localhost  
For this guide I'm going to use snort as my user, password and database. I would recommend you use something different, just note what it is. If you are logging to aother mysql server then change localhost to what ever ip the server is.
output database: log, mysql, user=snort password=snot dbname=snort host=localhost  
I don't know anything about mysql. I followed Patrick's guide word for word. Download snort from and extract it. Since my version of snort was 2.3.2 thats what I downloaded from Then we'll set up a database for snort.
mysql -u root
set password for root@localhost=password('PICK_A_PASSWORD');
create database snort;
grant insert,select on root.* to snort@localhost;
set password for snort@localhost=password('PASSWORD_SNORT_CONF');
grant create,delete,insert,select,update on snort.* to snort@localhost;
grant create,delete,insert,select,update on snort.* to snort;
Pay attention to the semicolons ;
Create the tables
mysql -u root -p < ~/snort-2.3.2/schemas/create_mysql snort  
Check the database
mysql -u root -p
show databases;
use snort
show tables;
You should be able to fire up snort with no problems.
sudo snort -c /etc/snort/snort.conf  
*I Updated this section and found adodb in the repository
Install apache our webserver and php with mysql & adodb
sudo apt-get install apache2 php5-mysql libphp-adodb  
Download base
Move base to /var/www, extract and delete the archive.
sudo mv base-1.2.2.tar.gz
cd /var/www
sudo tar -xvzf base-1.2.2.tar.gz
sudo rm base-1.2.2.tar.gz
mv base-1.2.2 base  
Edit the base configuration
sudo cp base/base_conf.php.dist base/base_conf.php
sudo vi base/base_conf.php  
$Base_urlpath = /base
$Dblib_path = /usr/share/adodb/;
Change line 85 and so on to match your mysql database. Such as the username, password etc.
I was expecting this to work but for some reason it didn't. I fired up firefox and went to localhost and when I clicked the folder base it kept trying to download a file. I tried restarting apache but the only thing that actually worked was a reboot. Go figure.
If you goto http://localhost/base you should see a link to the setup page. Click it and then click Setup Base AG. Now click home and Base should be up an running. 
Now in order to get the graph to work
sudo apt-get install php5-gd php-pear
sudo pear install Image_Color
pear install Image_Canvas-alpha
pear install Image_Graph-alpha  
Restart Apache and make sure snort is running
sudo /etc/init.d/apache2 restart
sudo /etc/init.d/snort start  
For some reason when I was trying to install Image_Color it was missing a dependency that was already installed. If you get the same error try the following.
sudo apt-get remove php5-gd
sudo apt-get install php5-gd  
This is my first HOWTO. Good luck & have fun.
