[Samba] Multiple Instancies of Samba on a single System

Hi out there,
             i intend to run multiple Instancies of Samba
on a single, multi-homed, server, with each instance bound
to a specific (logical) interface.

If this works, it would be fine to me. 
Mainly for administrative Reasons. (You won't believe, 
but from time to time it becomes necessary to restart
some services, but restarting the entire server is a
real mess)

Well here my questions:

 - Most important: 
   Can anyone out there tell me, that this is definitely impossible?

 - Most helpful: 
   Which settings must appear in the Configuration, to split the
   working-directories? (locks, logs, private-dir and so on)

 - Very interesting:
   Has anyone experience with such a configuration?

Thanks in advance
Gunther

[Samba] Multiple Instancies of Samba on a single System

Can anyone out there tell me, that this is definitely impossible?

Yes.  I have a freebsd machine with two ip addresses (one nic) and have a 
samba server bound to each address.

Which settings must appear in the Configuration, to split the
   working-directories? (locks, logs, private-dir and so on)

I did this in an easier way for me.  I installed two versions of samba!  (I 
am a lazy, lazy man.  Typing ./configure --prefix=/usr/local/samba-cvs; make 
; make install and the editing the smb.conf file seemed much less 
complicated to me) One under /usr/local/samba-cvs and one just under 
/usr/local.

Has anyone experience with such a configuration?

I only set up the second server so I could mess around with having a pdc on 
my network which would emulate the one at my wife's work for when she 
brought her laptop home without having to screw up the existing server.  It 
seems to work.

[Samba] Solution: Multiple Instancies of Samba on a single System

Hi out there,
             i asked the question, how to establish multiple
Samba-instancies on a single system. Well, nobody made objections
that this should work and apparently it really works with the following
setup:

- Compilation (config.status):
  (nothing special about it, except that i enforce the existance
   of /etc/smb.conf for samba to work properly)

   ./configure  --prefix=/opt/samba-2.2.3a \
   --localstatedir=/var/samba --with-configdir=/etc \
   --with-automount --with-syslog --with-quotas --with-utmp \
   --with-msdfs --with-vfs --with-libsmbclient --with-acl-support

   /opt/samba-2.2.3a is a shared, readonly directory on a central
   server, while /etc and /var are local, writable directories
   on different samba-servers.

-  Startup/Setup
   - The attached Shell-Script "samba" is my startup/shutdown
     script for the servers.

     - /etc/smb.conf-<Server> - is the instance-configuration
 
     - <Server> == zerberos is my PDC, which has an alter-Ego
       /etc/nmb.conf (/etc/nmb.conf is symlinked to /etc/smb.conf-zerberos)

       This is due to the fact, that apparently a Samba-PDC does
       not work without a running nmbd, which processes the 
       logon-packets. But only one nmbd must run on a single system.

     - /etc/smb.conf is a symlink to /etc/smb.conf-zerberos too,
       which is required for smbpasswd to work properly, due to
       my specific compilation.

    ## And _never_ name your PDC with the domain-name!! 

- Instance-Setups (smb.conf-devil1):

  As already seen in the zerberos-configuration, two parameters are 
  important to split the working-directories:

   log file                = /var/samba/devil1/log/%M.%m
   lock directory          = /var/samba/devil1/locks

   (devil1 has an alter-ego named devil2, which shares his locks
    and logs, what is the reason for the "config file"-parameter
    in the attached file)

And a final note:

  Both configurations bind to a single interface (32Bit Mask).

  The PDC also binds to the loopback-interface (for smbpasswd
  to work on this system. 

Hope that this helps others and sorry for this lengthly mail.

Regards
Gunther

P.S.: my `ps -axuww | fgrep samba` looks like this after /etc/init.d/samba start

root     22823  0.1  0.2 2488 1912 ?        S 23:44:43  0:00 nmbd -D -d 1 -H
/etc/lmhosts -l /var/samba/nmb/log -s /etc/nmb.conf

/var/samba/devil1/log -s /etc/smb.conf-devil1
root     22848  0.0  0.2 3456 1664 ?        S 23:44:44  0:00 smbd -D -d 1 -l

[Samba] Multiple Instancies of Samba on a single System

Yes, this works, however, you probably will want to build different
executables.  I first got it to work starting the daemons with
different configuration files, but then I had a problem with
smbpasswd: it has no config file option.  You can't make it
work differently for the different servers.  I just did multiple
configure/make runs:

     ./configure \
         --with-configdir=/etc/samba-red \
         --libdir=/etc/samba-red \
         --sharedstatedir=/var/samba-red/run \
         --localstatedir=/var/samba-red/run \
         --with-privatedir=/etc/samba-red/private \
         --with-lockdir=/var/samba-red/locks \
         ... && make &&
     make install INSTALLCMD="/bin/sh `/bin/pwd`/source/install-sh
-t='s/^/red-/'" &&

With this the smpbasswd that uses the /etc/samba-red/smb.conf file is named
"red-smbpasswd", etc.

However, to get the install to work correctly I needed to force the Makefile
to use the proper install-sh, not the in-line copies as the Makefile is
supplied.  The install-sh can do name translations.  The patch to make this
happen is:
