You MUST have libpcap installed in order to use Snort! It is available at ftp://ftp.ee.lbl.gov/libpcap.tar.Z
Some operating systems (e.g. all the BSD's) come with libpcap alredy installed, make sure you don't have already libpcap installed before grabbing it from LBL!
If you want to use the flexible response code, you need
to install Libnet

|Snort-panel||v1.0 build 10||Win32 GUI front end for the Win32 version of Snort||Xato Network Security, Inc|
|address_config.sh||v0.2||Handy script for laptop users that change their IP address frequently. This automates the process of updating your Snort rules file.||Sten Kalenda Apeldoorn|
|Dupl||v0.1.7||Snort rules beautifier, removes duplicate rules from snort rules files||Norz.org|
|Guardian||v1.0||Guardian watches the output from Snort, and uses ipchains to deny any further packets from the attacker to get to the system.||Anthony Stevens|

|snortwatch-0.7||v0.7||This is a little tool to help keep track of alerts generated by Snort. I've mostly tested snortwatch against version 1.5.x of snort and although the output of 1.6 seems very similar if not to say identical, theremay still be some type of alert I haven't come across that could throw off the parsing.||Yves Perrenoud|
|RotateLogs||v1||This script is used to backup and
then destroy log files by backing them up (optional) then removing them.

|snort_cleandb.pl||v1.7||This script goes through the data base and deletes the oldest entries
to make room for more fun.
Only works w/ postgresql right now but should be trivial to make work w/other db's
|hog-vim||v1||Adds syntax highlighting for Snort rules to the best editor in the world, vim.||Phil Wood|
|ruleset-retrieve||v1||Obtains ruleset from www.snort.org or whitehats.com and inserts your ip address into appropriate areas. Starts snort -c <ruleset> -D||Vacuum|
|Snorticus||v1.0.3||Snorticus is a collection of shell scripts designed to allow easy managment

|IDScenter||v1.08||IDScenter is a tool for setting up SNORT for Win32||Ueli Kistler|
|Getcontact||v1||Perl Script to pull contact information out of snort_portscan.log files. The program looks up the source ip numbers in the various registry databases and outputs the email address with the relevant portion of the log.||Robin Stubbs|
|LogSnorter||v 0.1||This perl script scans syslog messages (typically in real-time), picks
up any "reject packet" messages generated by Ciscos or Linux ipfw/ipchains
and logs them into your central Snort SQL database. This allows you to
the reach of snort without having to put snort out into wierd areas - like in front of your perimeter router/firewall...
With VB5 runtime libraries
Without VB5 runtime
|v1||This first utility is WinSnort2Html which takes the alert log files and parses them into a an HTML page. Since it is written in Visual Basic, the program requires VB 5.0 or later runtime libraries. The program runs on Windows 95/98/NT4/2000. There are two download links below; one includes the VB 5 runtime libraries and the other does not. Please check the readme file that contains some important information about configuring Snort to work with WinSnort2Html. WinSnort2Html is based on the perl script snort2html by Dan Swan.||Chris Koutras|
|Girr||v1||GIRR - Guardian IP-Chains Rules Remover
GIRR is a script which can be used along with
Guardian and snort.
When Guardian is run along with snort, it starts blocking
IP Addresses using ipchains. This is good when the sysadmin is not near the server or when he is away and no one else knows what to do.
The ipchains rules list may become huge and unmanageable. This script helps sysadmins to remove the ipchains rules.
Removing the rules should not be a problem, since if the hacker tries the same attack again he gets blocked again.
"Quick and Simple" Log Rotation

gzip -9 -c /var/log/snort.alert >> /var/log/snort.alert.`date "+%m%d%y"`.gz
From Bill Richardson
Great bash script to be run as a cron job....
if [ -f "/sniff/alert" ] ; then
cat /sniff/alert |mail -s
cat /sniff/alert >> /sniff/full-alert
cat /sniff/whoami >> /sniff/alert
cat /sniff/alert |smbclient -M workstation1
cat /sniff/alert |smbclient -M workstation2
rm -f /sniff/alert
The first line looks for the
alert file in this case in the /sniff directory if present send the contents
pipes to mail
the -s is the Subject and you can add as many email addresses as you like.
The second line takes the
alert file and adds it to a file called full-alert "You can call this what
the full-alert file in this case will have a copy of all alerts
The third line takes the contents of the file whoami "This is a text file that contains the name of the server running snort" adds it on to the end of the alert file. Now you can see what Snort Server the message came from....
Line four and five sends the
contents of the alert file + the server name that came from the whoami
file to what
ever box will take a winpopup message. Just add more lines per every workstation that you want to see the popups.
Line six deletes the alert file. Now when your cron job runs every "x" minutes IF and only IF the alert file is present will you get email and a winpop message.
With snort I could not get the
alert file to do more than one thing. I could send alerts via SMB, or to
the alert file but not both. Now I can do both plus e-mail.
From Craig Smith
Net-SnortLog-0.1.tar.gz | PassiveOS.tar.gz
Craig Smith has finished writing both the Passive OS detection for snort (log_dir and alert file) as well as a Perl module for manipulating snort log files. The perl module (Net::SnortLog) has a few different functions.
It can gather a list of files from the log_dir and
put them into an array for you (like all TCP files).
It can parse a snort log file into a special datastructure (either an alert file or one from the above function)
It can use the next_pkt function to analyze packet by packet with a structure like:
It should detect almost every part that is logged by
snort with just about any option at any layer (not -C). But you don't
have to worry much about the options from a programmer stand point.
It will figure out what options where used. Hopefully this will make
it easier for some of the other perl developers for Snort to start making
reports on the log_dir as well as the alert file.
