Configuring SWATCH

On MASTER

1. Create the configuration file for swatch:

        - Edit /usr/local/etc/swatch.conf -- use TAB and not SPACE
          for the lines below "watchfor"!

- - - - - - - - - - - - - - cut below - - - - - - - - - - - - -

watchfor /client ([0-9A-F.:]+)\D\d+: transfer of '(.*)\/IN': .XFR/
        mail=adm,subject=Zone AXFR
        threshold type=limit,count=1,seconds=600

- - - - - - - - - - - - - - cut above - - - - - - - - - - - - -


2. Enable the mail server

        - Add to /etc/rc.conf

        postfix_enable="YES"

        # newaliases
        # /usr/local/etc/rc.d/postfix start

3. Try sending mail to yourself

        $ echo hello | mail adm@master.grpX.ws.nsrc.org

        See if the mail has arrived:

    $ mutt -f /var/mail/adm

4. Start swatch:

        # swatch -c /usr/local/etc/swatch.conf --tail-file=/etc/namedb/log/transfers --daemon

    # ps axuww | grep swatch

   You should see a line like the following:

   root 58811  0.0  0.0 11500  2124   5  RJ   11:41AM   0:00.02 /usr/local/bin/perl /usr/local/bin/swatch -c /usr/local/etc/swatch.conf --tail-file=/etc/namedb/log/transfers --daemon

7. Ask another group to perform a zone transfer of your zone:

        From their machine:

        # dig @master.grpX.ws.nsrc.org YOURTLD axfr             (where X is YOUR group)

        Q: do they get a copy of your zone ?
        Q: do you get an email about it ?

8. Check that mails are coming in:

    # mutt -f /var/mail/adm
        
   Note the information contained in the message.
