[Samba] HomeDir with machinenname

[kissg]

Dear Marc,

it's always a good idea to read man pages (this is from the smb.conf man
page):

"%m
          the NetBIOS name of the client machine (very useful).

          This parameter is not available when Samba listens on port  445,
as
          clients no longer send this information. If you use this macro in
an
          include statement on a domain that has a Samba domain controller
be
          sure to set in the [global] section smb ports = 139. This will
cause
          Samba to not listen on port 445 and will permit include
functional$B!>(B
          ity to function as it did with Samba 2.x."

So, according to this, you should add an entry to the [global] section of
your smb.conf file:

smb ports = 139

Another thing to note, is that you have to write a script, that creates the
machine's directory, if it doesn't exist yet and instruct Samba to run the
script, when a user logs in.

To do this, add the following to the [netlogon] share in smb.conf:

root preexec = /usr/local/sbin/createmachinedir.sh %m %u

This script will test if the username is "general" and create a directory
with the name of the machine where the user has logged in from.

Create a file in the directory /usr/local/sbin, named "createmachinedir.sh"
and copy the followings to it:

######### Script start #########

#!/bin/sh

SHAREPATH="/shares/Public/general"

if [ ! -e "$SHAREPATH/$1" -a "$2" = "general"]
then
   mkdir "$SHAREPATH/$1"
   # Set permissions with chown and chmod:
   # "general" will be the owner of this directory:
   chown general:users "$SHAREPATH/$1"
   # We give access only to "general" for this machine directory
   # (correct this if you want to grant permissions to other users, too)
   chmod 0700 "$SHAREPATH/$1"
fi
exit 0

######### End of script #########

Save the script and set the executable bit:

chmod a+x /usr/local/sbin/createmachinedir.sh

The next step is, to map the correct directory when the user logs in. This
can be achieved by adding the following command to the user's logon script:

net use Z: %LOGONSERVER%\Public\general\%COMPUTERNAME%

You can use any drive letter instead of Z:, just make sure, it is not
already taken.

I think, this could provide a perfect solution to your problem. By the way,
I use a similar script to create home directories for domain users, when
they log in for the first time.

Please tell me whether this method works for you or not.

Best regards:
Gergely Kiss
