7 A more up to date version of this howto can be found in the wiki
8 at http://wiki.samba.org/index.php/Samba4/HOWTO.
10 This is a very basic document on how to setup a simple Samba4
11 server. This is aimed at developers who are already familiar with
12 Samba3 and wish to participate in Samba4 development. This is not
13 aimed at production use of Samba4.
16 Step 1: download Samba4
17 -----------------------
19 There are 2 methods of doing this:
21 method 1: "rsync -avz samba.org::ftp/unpacked/samba4 ."
23 method 2: "svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0 samba4"
25 both methods will create a directory called "samba4" in the current
26 directory. If you don't have rsync or svn then install one of them.
28 Since only released versions of Samba contain a pregenerated configure script,
29 you will have to generate it by hand:
34 Note that the above rsync command will give you a checked out svn
35 repository. So if you also have svn you can update it to the latest
36 version at some future date using:
41 Step 2: compile Samba4
42 ----------------------
44 Recommended optional development libraries:
45 - acl and xattr development libraries
55 If you have gcc 3.4 or newer, then substitute "pch" for "proto" to
56 greatly speed up the compile process (about 5x faster).
58 Step 3: install Samba4
59 ----------------------
61 Run this as a user who have permission to write to the install
62 directory (defaults to /usr/local/samba). Use --prefix option to
63 configure above to change this.
68 Step 4: provision Samba4
69 ------------------------
71 The "provision" step sets up a basic user database. Make sure your smbscript
72 binary is installed in a directory listed in your PATH environment variable.
73 It is presumed it's available just like any other commands from your shell.
74 Must be run as a user with permission to write to the install directory.
77 # ./setup/provision --realm=YOUR.REALM --domain=YOURDOM --adminpass=SOMEPASSWORD
79 REMINDER: Add the "bin" directory of the path you installed to
80 (e.g. /usr/local/samba/bin) to your path, or the provision command
83 'YOURDOM' is the NT4 style domain name. 'YOUR.REALM' is your kerberos
84 realm, which is typically your DNS domain name.
86 Step 5: Create a simple smb.conf
87 --------------------------------
89 The provisioning will create a very simple smb.conf with no shares by
90 default. You will need to update it to add at least one share. For
98 Step 6: starting Samba4
99 -----------------------
101 The simplest is to just run "smbd", but as a developer you may find
102 the following more useful:
106 that means "start smbd without messages in stdout, and running a
107 single process. That mode of operation makes debugging smbd with gdb
110 Note that now it is no longer necessary to have an instance of nmbd
111 from Samba 3 running. If you are running any smbd or nmbd processes
112 they need to be stopped before starting smbd from Samba 4.
114 Make sure you put the bin and sbin directories from your new install
115 in your $PATH. Make sure you run the right version!
118 Step 7: testing Samba4
119 ----------------------
123 $ smbclient //localhost/test -Uadministrator%SOMEPASSWORD
125 $ ./script/tests/test_posix.sh //localhost/test administrator SOMEPASSWORD
128 NOTE about filesystem support
129 -----------------------------
131 To use the advanced features of Samba4 you need a filesystem that
132 supports both the "user" and "system" xattr namespaces.
134 If you run Linux with a 2.6 kernel and ext3 this means you need to
135 include the option "user_xattr" in your /etc/fstab. For example:
137 /dev/hda3 /home ext3 user_xattr 1 1
139 You also need to compile your kernel with the XATTR and SECURITY
140 options for your filesystem. For ext3 that means you need:
142 CONFIG_EXT3_FS_XATTR=y
143 CONFIG_EXT3_FS_SECURITY=y
145 If you are running a Linux 2.6 kernel with CONFIG_IKCONFIG_PROC
146 defined you can check this with the following command:
148 $ zgrep CONFIG_EXT3_FS /proc/config.gz
150 If you don't have a filesystem with xattr support, then you can
151 simulate it by using the option:
153 posix:eadb = /usr/local/samba/eadb.tdb
155 that will place all extra file attributes (NT ACLs, DOS EAs, streams
156 etc), in that tdb. It is not efficient, and doesn't scale well, but at
157 least it gives you a choice when you don't have a modern filesystem.
159 Testing your filesystem
160 -----------------------
162 To test your filesystem support, install the 'attr' package and run
163 the following 4 commands as root:
166 # setfattr -n user.test -v test test.txt
167 # setfattr -n security.test -v test2 test.txt
168 # getfattr -d test.txt
169 # getfattr -n security.test -d test.txt
171 You should see output like this:
177 security.test="test2"
179 If you get any "Operation not supported" errors then it means your
180 kernel is not configured correctly, or your filesystem is not mounted
181 with the right options.
183 If you get any "Operation not permitted" errors then it probably means
184 you didn't try the test as root.
