[Snort-users] E-mail alerting

I'm now thinking it may be a Mail problem, because I can't send a test
message to the mailserver.  I know this isn't the place for mail support,
but just hoping someone would be able to give input either way by looking at
my mail test:
----------------------------------------------------------------------------

  this is line 125 that was giving me the error before I removed the ADDRESS
portion of the mail command:
  --------------------------------------------------------------------------
------------------------------------------------
   $swatch_last_flush = $swatch_time_now;
      }

      if (/Priority/) {
          &Swatch::Actions::send_email('ADDRESSES' => "andy\@page55.com",
'MESSAGE' => "$_", 'SUBJECT' => "--- Snort IDS Alert ---", );
          &Swatch::Actions::exec_command('MESSAGE' => "$_", 'COMMAND' =>
"echo $0 >> /var/log/snort", );
        next;
  --------------------------------------------------------------------------
-------------------------------------

  AND FYI, I DID verify that snort is actively logging .....

  thanks,
  Andy

    Ok, I think I'm getting close.


    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 at ...12350... 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 at ...12350... 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 at ...10224... with subject of the email
           ##   being "----Snort IDS Alert----"
           ##  Log in file /var/log/IDS-scans


           watchfor /Priority/
          # echo green_h
           mail andy at ...12349... ,subject=--- Snort IDS Alert ---
           exec echo $0 >> /var/log/snort

    Any ideas, I've got to be sooooo close.....

    Thanks,

    Andy

      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"
