Samba4 developer howto
-----------------------
+======================
tridge@samba.org, December 2004
+A more up to date version of this howto can be found in the wiki
+at http://wiki.samba.org/index.php/Samba4/HOWTO.
This is a very basic document on how to setup a simple Samba4
server. This is aimed at developers who are already familiar with
Samba3 and wish to participate in Samba4 development. This is not
aimed at production use of Samba4.

Step 1: download Samba4
-----------------------
+If you have downloaded the Samba4 code via a tarball released from the
+samba.org website, Step 1 has already been completed for you. For testing
+with the version released in the tarball, you may continue on to Step 2. Note
+that the references below to the top-level directory named "samba4" will
+instead be based on the name of the tarball downloaded (e.g.
+"samba-4.0.0alpha3" for the tarball samba-4.0.0alpha3.tar.gz).
+
There are 2 methods of doing this:
- method 1: "rsync -avz samba.org::ftp/unpacked/samba4 ."
+ method 1: "rsync -avz samba.org::ftp/unpacked/samba_4_0_test/ samba4"
- method 2: "svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0 samba4"
+ method 2: "git clone git://git.samba.org/samba.git samba4; cd samba4 && git checkout -b v4-0-test origin/v4-0-test; cd .."
both methods will create a directory called "samba4" in the current
-directory. If you don't have rsync or svn then install one of them.
+directory. If you don't have rsync or git then install one of them.
-Note that the above rsync command will give you a checked out svn
-repository. So if you also have svn you can update it to the latest
-version at some future date using:
+Since only released versions of Samba contain a pregenerated configure script,
+you will have to generate it by hand::
- $ cd samba4
- $ svn up
+ $ cd samba4/source
+ $ ./autogen.sh
+Note that the above rsync command will give you a checked out git
+repository. So if you also have git you can update it to the latest
+version at some future date using::
+
+ $ cd samba4
+ $ git pull origin v4-0-test
Step 2: compile Samba4
----------------------
-Run this:
+Recommended optional development libraries:
+- acl and xattr development libraries
+- gnutls
+- readline
+
+Run this::
$ cd samba4/source
- $ ./autogen.sh
- $ ./configure.developer -C
+ $ ./configure
$ make
-If you have gcc 3.4 or newer, then run "make pch" before "make" to
-greatly speed up the compile process (about 5x faster).
-
-
Step 3: install Samba4
----------------------
Run this as a user who have permission to write to the install
directory (defaults to /usr/local/samba). Use --prefix option to
configure above to change this.
+
+::
# make install
------------------------
The "provision" step sets up a basic user database.
+Must be run as a user with permission to write to the install directory.
- $ cd source
- $ ./setup/provision.pl --realm=YOUR.REALM --domain=YOURDOM --adminpass=SOMEPASSWORD
+::
-This will create a number of new 'ldb' database files in a directory
-newdb.XXX. You need to move these to the "private" subdirectory of
-your install. For example:
-
- # mv newdb.123/*.ldb /usr/local/samba/private/
+ # cd source
+ # ./setup/provision --realm=YOUR.REALM --domain=YOURDOM \
+ # --adminpass=SOMEPASSWORD --server-role='domain controller'
+'YOURDOM' is the NT4 style domain name. 'YOUR.REALM' is your kerberos
+realm, which is typically your DNS domain name.
Step 5: Create a simple smb.conf
--------------------------------
-You need to create a smb.conf file in the lib/ directory of your
-install. The default is /usr/local/samba/lib/smb.conf. A minimal
-smb.conf would be:
-
- workgroup = YOURDOM
+The provisioning will create a very simple smb.conf with no shares by
+default. You will need to update it to add at least one share. For
+example::
[test]
path = /data/test
read only = no
-The workgroup must exactly match the --domain argument you gave to provision.pl
-
Step 6: starting Samba4
-----------------------
The simplest is to just run "smbd", but as a developer you may find
-the following more useful:
+the following more useful::
- # smbd -i -M single -d3
+ # smbd -i -M single
that means "start smbd without messages in stdout, and running a
-single process, with level 3 debugging". That mode of operation makes
-debugging smbd with gdb particularly easy.
+single process. That mode of operation makes debugging smbd with gdb
+particularly easy.
Note that now it is no longer necessary to have an instance of nmbd
from Samba 3 running. If you are running any smbd or nmbd processes
Step 7: testing Samba4
----------------------
-try these commands:
+try this command::
- $ smbclient //localhost/test -Uadministrator%SOMEPASSWORD
- or
- $ ./script/tests/test_posix.sh //localhost/test administrator SOMEPASSWORD
+ $ smbclient //localhost/test -Uadministrator%SOMEPASSWORD
NOTE about filesystem support
supports both the "user" and "system" xattr namespaces.
If you run Linux with a 2.6 kernel and ext3 this means you need to
-include the option "user_xattr" in your /etc/fstab. For example:
+include the option "user_xattr" in your /etc/fstab. For example::
-/dev/hda3 /home ext3 user_xattr 1 1
+ /dev/hda3 /home ext3 user_xattr 1 1
You also need to compile your kernel with the XATTR and SECURITY
-options for your filesystem. For ext3 that means you need:
+options for your filesystem. For ext3 that means you need::
CONFIG_EXT3_FS_XATTR=y
CONFIG_EXT3_FS_SECURITY=y
If you are running a Linux 2.6 kernel with CONFIG_IKCONFIG_PROC
-defined you can check this with the following command:
+defined you can check this with the following command::
$ zgrep CONFIG_EXT3_FS /proc/config.gz
If you don't have a filesystem with xattr support, then you can
-simulate it by using the option:
+simulate it by using the option::
posix:eadb = /usr/local/samba/eadb.tdb
-----------------------
To test your filesystem support, install the 'attr' package and run
-the following 4 commands as root:
+the following 4 commands as root::
# touch test.txt
# setfattr -n user.test -v test test.txt
# getfattr -d test.txt
# getfattr -n security.test -d test.txt
-You should see output like this:
+You should see output like this::
# file: test.txt
user.test="test"
-
+
# file: test.txt
security.test="test2"
If you get any "Operation not permitted" errors then it probably means
you didn't try the test as root.
