[Snort-users] E-mail alerting

Hi Prabu,

I cannot find this file. 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 .....

Andy

  Hi Andy,
        I was busy with my work for past three days,I didn't even check
snort list.Just now,I checked my mails,saw ur request.Well,I could not get
into a conclusion,what might be the error.Send the line in ur
script(ie,/root/.swatch_script.3238 ),where the error points out.I think,the
mail-id was the problem
  for the error.

  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.



  Cheers,
  Prabu.S

    Hi Prabu,

    Excellent post, it prompted me to check out 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 at ...12350... 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.)

    Thanks,

    Drew

      Hello Carlos,
                  You can use Swatch to get emails alerts from Snort.

       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.............................

      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 at ...10224... with subject of the
email
             ##   being "----Snort IDS Alert----"
             ##  Log in file /var/log/IDS-scans


             watchfor /Priority/
             echo green_h
             mail addresses=youruseraccount at ...12390... ,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"

is ther eany manual about that?

        Thanks in advance.
