OK, the mail issue is fixed. I needed to add "tunes.page55.com" to my relay_from_host list in the mail servers main config file. AND Swatch works! Thanks to all who gave their input. This issue is offically closed!

In /etc/swatchrc.txt, I removed the ADDRESS part of the mail command, and swatch now runs, AND the /root/.swatch_script.1234 file is created and I can actually find it. I get this: *** swatch version 3.1.1 (pid:2009) started at Sat Sep 18 19:44:05 CDT 2004 To test, I did a port scan, and this popped up: Invalid attribute name green_h at /usr/lib/perl5/site_perl/5.6.1/Swatch/Actions.pm line 58 I commented the "echo green_h" line out, and I don't get the "Invalid attribute name........" error anymore. Still not getting email alerts however. Do I need the "echo green_h" ? I would think not.... Next, I changed the logging path, to /var/log/snort to match snort: [root@tunes andy]# snort -c /etc/snort/snort.conf -l /var/log/snort Running in IDS mode Log directory = /var/log/snort Still not getting email alerts however. This is my current swatchrc file: [root@tunes etc]# more swatchrc.txt # Swatch configuration file # # # swatch -c /etc/swatchrc -t /var/log/snort/alert # ### Snort Alerts ## Watch for entries containing the word 'Priority' in the snort alert file. ## Display it in green on the screen ## Mail alert to alerts () yourdomain com with subject of the email ## being "----Snort IDS Alert----" ## Log in file /var/log/IDS-scans watchfor /Priority/ # echo green_h mail andy () page55 com ,subject=--- Snort IDS Alert --- exec echo $0 >> /var/log/snort Any ideas, I've got to be sooooo close.....

Locate does not find any files named swatch_script.* Snort and Swatch are installed on the "tunes.page55.com" server, and the mailserver I want alerts to be sent to is another server called "page55.com" Do I need a mail client running on Tunes? Sendmail is there by default. I'm not sure how it works, but I'm guessing that Snort would use the default email client to send an email... Thankyou for your reply, I wish I could get you the script info... I will continue hunting .....

First,R u running snort on "page555" server or "tunes" server.What is the hostname of the machine,where u have installed Snort and Swatch. See,u can send alerts to the useraccounts on the machine,where u have installed all thoses stuffs.So change the email-id in the configuration file. This would help U,I hope. NOTE: /root/.swatch_script.3238 ----.this is the script that is generated automatically,while running swatch.

I had to install the CPAN mods and the only thing different was that I had to install Time-HiRes-1.63 instead of Time-HiRes-1.59 They all installed ok. I'm trying to get swatch to read the config file. I followed the directions, but I'm getting an error: [root@tunes etc]# swatch --config-file=/etc/swatchrc.txt Global symbol "@page55" requires explicit package name at /root/.swatch_script.3238 line 125. Execution of /root/.swatch_script.3238 aborted due to compilation errors. I put the config file in /etc and copied it exactly from below, except of course I inserted my own email address. Do you know what this error means? What is the meaning of the line: /root/.swatch_script.3238 line 125. (specifically the /root/ part.)

Installing Swatch,is just a child's play,very easier.I have given below the necessary steps to configure Swatch. Hope,this will be useful.If you have,any queries,you can write to me............................. Prabu.S ############################################################################ ############################################ CONFIGURATION STEPS TO SEND SNORT ALERTS AS E-MAIL: To receives Snort alerts as E-mail, one can follow the following steps: Swatch is the widely used open source tool to enable E mail alerts in Snort. Swatch is a utility that monitors system log files, filters out unwanted data and takes specified actions (i.e., sending email, executing a script, etc.) based upon what it finds in the log files. So I have used Swatch to configure snort to send the alerts as E-mail. NOTE: Here, it is considered that snort have been already installed on the host, in which this is to be tested. [a] Swatch installation: Download the swatch package, from http://sourceforge.net/project/showfiles.php?group_id=68627 To install, simply issue the following commands: perl Makefile.PL make make test make install make realclean Swatch installs just like a CPAN module. If you are not familiar with this process then you may want to read about it by issuing the command: man ExtUtils::MakeMaker Use the perldoc command if your man cannot find the document. If you see messages like these: Warning: prerequisite Date::Calc 0 not found at (eval 1) line 219. Warning: prerequisite Date::Parse 0 not found at (eval 1) line 219. Warning: prerequisite File::Tail 0 not found at (eval 1) line 219. Warning: prerequisite Time::HiRes 1.12 not found at (eval 1) line 219. Then you need to install the CPAN module(s) that it doesn't find, before you can use swatch. You can find these modules at http://search.cpan.org/. One must download following perl modules from the site search.cpan.org 1.Bit-Vector-6.3 2.Date-Calc-5.3 3.DateManip-5.42a 4.File-Tail-0.98 5.Time-HiRes-1.59 6.TimeDate-1.16 To install these perl modules,one can follow the same steps as said per Swatch, They are, perl Makefile.PL make make test make install make realclean The Swatch binary will be installed at the /opt/perl/bin/ directory Then create the swatch configuratiobn file. cat /etc/swatchrc.txt ========================================================== # Swatch configuration file # # # swatch -c /etc/swatchrc -t /var/log/snort/alert # ### Snort Alerts ## Watch for entries containing the word 'Priority' in the snort alert file. ## Display it in green on the screen ## Mail alert to alerts () yourdomain com with subject of the email ## being "----Snort IDS Alert----" ## Log in file /var/log/IDS-scans watchfor /Priority/ echo green_h mail addresses=youruseraccount () yourdomain comt ,subject=--- Snort IDS Alert --- exec echo $0 >> /var/log/IDS-scans ============================================================ THE FINAL STEPS: [a] Start Snort in NIDS mode: #./snort -c /snort/iexpress/snort/etc/snort.conf -l /var/log/snort. [b] Start swatch: cd /opt/perl/bin #./swatch --config-file=/etc/swatchrc.txt [c] Using Outlook Express: configure the User's POP3 account and you can recieve the emails send by Swatch for each alerts based on the patter matching the "watchfor" ############################################################################ ############################## Cheers, Prabu.S ----- Original Message ----- From: Carlos M Ospina To: snort-users () lists sourceforge net Sent: Friday, September 03, 2004 7:08 PM Subject: [Snort-users] E-mail alerting Is there anyway to configure, with acid, automatic alerts by e-mail? is ther eany manual about that?
