[Samba] Clustered Samba Printing

[christoph.beyer at desy.de]

Hi Bill,

I am using clustered samba printing for a couple of years and it works fine, 
this is my setup:

3 sun server with sun cluster, let's call them samba1 samba2 and samba3 are 
individually joined to the windows domain using the hostnames samba1/2/3.

Through the sun cluster they use together a shared address called 'printserver' 
with the 'bind interface only' option set to the shared hostname I have a 
loadbalanced samba setup for printing.

To make sure all server use the same config I have 'ntforms.tdb', 
'printers.tdb' and 'ntdrivers.tdb' on a shared global storage, linked via 
symlink into the three local samba/var/locks dirs. The 'samba printcap' is 
shared globally as well as the 'drivers' dir of cause.

One thing about this construction is that samba1/2/3 still and always publish 
the printers over ther local ip adress though they will not accept a connection 
over these adresses. You need a firewall to get rid of this or unconfigure 
those printer in the AD.

For some reason I have a cron restart running every morning, this is nice to 
get rid of old processes and connections and to have a fresh start from the 
ground for all three nodes...

Hope this helps, don't hesitate to write me e-mail if you have further 
questions, well and maybe I got it all wrong and there is a much more clever 
idea about clustered printing, love to hear something about it then 
;)

cheers
   christoph
