Sync multiple servers

[Julian Field]

Read "man rsync" :-)

You can do your entire MailScanner config (on your primary config host, 
which might be a Linux box) with
rsync -av --rsh=ssh /etc/MailScanner/ 
root at second.mail.host.com:/etc/MailScanner/
If you want to see what it will do, but without actually doing it, add 
"--dry-run" to the list of options near the start of that command.

You'll need to set up ssh keys so that the primary config host can 
successfully
ssh root at second.mail.host.com date
without asking for a password. Then you can bung it in a crontab entry 
and it will do it regularly. Personally I prefer to do it just on 
demand, so typing in a password isn't a big deal, and makes me stop and 
think before I do it (which I regard as a good thing :-)

You could copy the sendmail configuration similarly by copying 
/etc/aliases* and /etc/mail/ the same way.
Once you have copied the files over, do an
ssh root at second.mail.host.com /sbin/service MailScanner restart
to force it to start up afresh with the new configuration files in place.

Do it with a nice new copy of MailScanner and the service MailScanner 
restart will reliably and completely do the job, I recently improved it. 
If your "service MailScanner restart" prints "....5....0 "then you have 
a recent enough version. If it just prints a long string of dots, 
without any digits every 5th dot, then you need a more recent version of 
the init.d script.

Best regards,
Jules.
