Intrusion Detection With BASE And Snort - Page 2


Go to: and select a download link for Libpcap (at time of writing this it is libpcap-0.9.4.tar.gz)
cd back to the snorttemp map:

cd /root/snorttemp

and download the libpcap-0.9.4.tar.gz file:


Untar the file:

tar -xvzf libpcap-0.9.4.tar.gz

Remove the file:

rm libpcap-0.9.4.tar.gz

BASE (Basic Analysis and Security Engine )

Go to: and download the latest release (at time of writing BASE 1.2.5 (sarah))
cd back to the snorttemp map:

cd /root/snorttemp

and download the base-1.2.5.tar.gz file:


Untar the file:

tar -xvzf base-1.2.5.tar.gz

Remove the file:

rm base-1.2.5.tar.gz

ADOdb: (ADOdb Database Abstraction Library for PHP (and Python).)

Go to: and download the latest release (at time of writing adodb-490-for-php)
cd back to the snorttemp map:

cd /root/snorttemp

and download the adodb490.tgz file:


Untar the file:

tar -xvzf adodb490.tgz

Remove the file:

rm adodb490.tgz

ls should now show the following directorys in /root/snorttemp:
adodb, base-1.2.5, libpcap-0.9.4, pcre-6.3 and snort-2.6.0

adodb, libpcap, base-1.2.5, pcre, snort

After editing the "user", "password" and "dbname" (on page 3) its time to make a new SQL database.

Login to your SQL server

mysql -u root -p
(Enter password)

mysql> create database snort;
mysql> exit

Now that you have a SQL database ready, we can use the SNORT schemas for the proper layout.

mysql -D snort -u root -p < /root/snorttemp/snort-2.6.0/schemas/create_mysql
(Enter password)

Finally we are ready to test snort.

snort -c /etc/snort/snort.conf

what is you get an error that says parsing rules file "/etc/snort/snort.conf"

 error: /etc/snort/snort.conf(1) Invalid configuration line :FdF#..................................................

From: Anonymous at: 2006-08-10 16:56:58

If you get:
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
when running:

./configure --enable-dynamicplugin --with-mysql

You may need to install the gcc c++ compiler.

Just run:

apt-get install g++

...and when it's finished, rerun the configure command, and you should be sorted out.

if you running test snort.

snort -c /etc/snort/snort.conf

and get an error like this : 

ERROR: ERROR /etc/snort/rules/web-misc.rules Line 452 => unable to parse pcre regex "fn=Eye\d{4}_\d{2}.log/Rmsi"
Fatal Error, Quitting..

Solution :

you must edit file /etc/snort/rules/web-misc.rules with your favorite text editor, on Line 452 . and :

change/add line above :

with :

Just add '/' in front line.

Hi @ all,

 I ran into some issues with my snort install on Debain 5r2. And I thought, it might be helpful to post the solutions I found:

1.  While ./configure... I got mysql.h not found

You need to install the package libmysqlclient-dev

2. Loading dynamic detection library /usr/local/lib/snort_dynamicrules/ ERROR: Failed to load /usr/local/lib/snort_dynamicrules/ /usr/local/lib/snort_dynamicrules/ cannot open shared object file: No such file or directory
Fatal Error, Quitting..

This one can be fixed by copying all files from <snort_src_folder>/so_rules/precompiled/Debian-Lenny/i386/2.8.4/ to /usr/local/lib/snort_dynamicrules/

3. When trying to start snort, I also got the following: ERROR: ERROR /etc/snort/rules/exploit.rules(23): Couldn't resolve hostname HOME_NET
Fatal Error, Quitting..

 That was tricky one, since it wasn't that easy to localize the evil's root. In snort.conf you have to change the line:




Because the Dollar-sign is missing there.

Hope this helps a few unlucky as I was ;-)

thanks.....this tutorial helped me out a lot.

From: Anonymous at: 2006-07-10 21:30:13

Nice, easy to follow tutorial. Keep up the good work!

It's been a while that I've been meaning to get back to using snort. I think I'll give a try sometime this week. Never used BASE, I'll probably try it out this Wednesday.

Good Stuff.

 Not bad actually, but the project still not grow up, if you use commercial variants you know this is nowhere comparing to them...

From: kav5 at: 2006-09-08 19:51:18

Looks good but it is not complete. It would be very nice to add snortsam installation to the tutorial because it implements IPS system. (to block attacker automatically)

 If u get these :

Warning: include_once(Mail.php) [function.include-once]: failed to open stream: No such file or directory in /var/www/web/base-php4/includes/ on line 29



 Try issuing these commands and see if it helps:

pear install Mail
pear install Mail_Mime

Also folks,

to get the graphics working by country and world maps:

There are 2 files: 

1. world_map6.png

2. world_map6.txt

do a search:

find / -iregex ".*world_map6.png"

you will find the file...then copy it to where your "PEAR directory" is

You will find your "PEAR directory" after you execute :

pear config-show

Then copy the 2 files in the "PEAR directory" under /Image/Graph/Images/Maps/

so the FULL path should look something like this:



That solevs one of the problems ...then you get an error like ".... couldn find...or not defined $GeoIPfree_file_ascii and $ip2cc"...something of the sort...for this purpose in your cmd execute:

perl -MCPAN -e 'install  Geography::Countries'


 perl -MCPAN -e 'install  IP::Country'

ok...almost there

then find your  base_conf.php  - should be somewhere in your /var/www/ directory  or the directories inder that

edit the file /base_conf.php/   towards the end you will find 

" $IP2CC..." uncomment that ...maybe restart your browser or clear the cahce of your browser and you are ready to go!!!

thats it

From: wisedud2u at: 2010-04-05 10:43:49

after you install the Geography::Countries do this

root@a3s:~#  cd /usr/lib/perl5/site_perl/5.8.8/Geo/


 root@a3s:Geo#perl ./ipscountry.dat /path/to/your/htdocs/base/ips-ascii.txt

This guide is a pretty good start but I actually found Patrick Harper's guide to be more in-depth. His guide is available at which I've used to develop a Snort/Centos/BASE install cd that I'm calling EasyIDS.

Thanks a lot for your tutorial. It allowed me to get everything up and running in a very short time.

From: Bob at: 2015-03-11 21:22:52

Doesn't look like the latest version of snort contains the needed mysql plugin so it doesn't look like based can be used as it interfaces with mysql.  Can someone verify this?
