samba - Jan 2007 - Dual Computer Names

Does anyone know if there is a way to setup a Samba server to respond to
2 different names on the same or different IP addresses?  I currently
have two servers with two different names.  I would like to decommission
the first server while still allowing users to access the second server
with the same name they were using to access the first server.

Thank You,
Jason Williard

Assuming you are dealing with fully Active-Directory integrated servers,
then the most effective solution would be to assign two IP addresses to
the same box, and run two separate instances of Samba - each with a
different config.

i.e.

one instance of winbind (I'm assuming both servers are part of the same
AD realm)
smbd -D -s /etc/samba/smb-1.conf
nmbd -D -s /etc/samba/smb-1.conf
smbd -D -s /etc/samba/smb-2.conf
nmbd -D -s /etc/samba/smb-2.conf

smb-1.conf and smb-2.conf define the different hostnames, shares and
sets "bind interfaces only = Yes" and uses the
"interfaces = eth:?" option to tell each instance what IP
address/interface it needs to exclusively bind to.


I just went through the same exercise - and the above works well for us.
Kerberos really wants to stop you assigning multiple names to the same
token (at least I had huge trouble getting it to work correctly), so
mapping everything to separate IPs is the cleanest IMHO.

Just add 'netbios aliases = <second-name>' to your smb.conf.
Or put an appropriate cname into your dns, depending on how
your clients resolve their names.

If you want different shares on each server, you might want
to add

smb ports = 139
include = /etc/samba/smb.conf.%L

to your smb.conf. You would add the shares for serverone to
the file /etc/samba/smb.conf.serverone and for servertwo
likewise to /etc/samba/smb.conf.servertwo.
