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. + +.. contents:: + +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/samba_4_0_test/ 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 git then install one of them. + +Since only released versions of Samba contain a pregenerated configure script, +you will have to generate it by hand:: + + $ 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 +---------------------- + +Recommended optional development libraries: +- acl and xattr development libraries +- gnutls +- readline + +Run this:: + + $ cd samba4/source + $ ./configure + $ make + +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 + + +Step 4: provision Samba4 +------------------------ + +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 --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 +-------------------------------- + +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 + + +Step 6: starting Samba4 +----------------------- + +The simplest is to just run "smbd", but as a developer you may find +the following more useful:: + + # smbd -i -M single + +that means "start smbd without messages in stdout, and running a +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 +they need to be stopped before starting smbd from Samba 4. + +Make sure you put the bin and sbin directories from your new install +in your $PATH. Make sure you run the right version! + + +Step 7: testing Samba4 +---------------------- + +try this command:: + + $ smbclient //localhost/test -Uadministrator%SOMEPASSWORD + + +NOTE about filesystem support +----------------------------- + +To use the advanced features of Samba4 you need a filesystem that +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:: + + /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:: + + 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:: + + $ 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:: + + posix:eadb = /usr/local/samba/eadb.tdb + +that will place all extra file attributes (NT ACLs, DOS EAs, streams +etc), in that tdb. It is not efficient, and doesn't scale well, but at +least it gives you a choice when you don't have a modern filesystem. + +Testing your filesystem +----------------------- + +To test your filesystem support, install the 'attr' package and run +the following 4 commands as root:: + + # touch test.txt + # setfattr -n user.test -v test test.txt + # setfattr -n security.test -v test2 test.txt + # getfattr -d test.txt + # getfattr -n security.test -d test.txt + +You should see output like this:: + + # file: test.txt + user.test="test" + + # file: test.txt + security.test="test2" + +If you get any "Operation not supported" errors then it means your +kernel is not configured correctly, or your filesystem is not mounted +with the right options. + +If you get any "Operation not permitted" errors then it probably means +you didn't try the test as root. + +.. + vim: ft=rest -- cgit
