You can obtain the Samba source file from the Samba Web site. To obtain a development version, you can download Samba from Subversion or using rsync.
Samba is developed in an open environment. Developers use a Subversion to “checkin” (also known as “commit”) new source code. Samba's various Subversion branches can be accessed via anonymous Subversion using the instructions detailed in this chapter.
This chapter is a modified version of the instructions found at the Samba Web site.
The machine samba.org runs a publicly accessible Subversion repository for access to the source code of several packages, including Samba, rsync, distcc, ccache, and jitterbug. There are two main ways of accessing the Subversion server on this host.
You can access the source code via your favorite WWW browser. This allows you to access the contents of individual files in the repository and also to look at the revision history and commit logs of individual files. You can also ask for a diff listing between any two versions on the repository.
Use the URL http://svnweb.samba.org/.
You can also access the source code via a normal Subversion client. This gives you much more control over what you can do with the repository and allows you to check out whole source trees and keep them up to date via normal Subversion commands. This is the preferred method of access if you are a developer and not just a casual browser.
In order to be able to download the Samba sources off Subversion, you need a Subversion client. Your distribution might include one, or you can download the sources from http://subversion.tigris.org/.
To gain access via anonymous Subversion, use the following steps.
Procedure 41.1. Retrieving Samba using Subversion
Install a recent copy of Subversion. All you really need is a copy of the Subversion client binary.
Run the command
svn co svn://svnanon.samba.org/samba/trunk samba.
This will create a directory called
samba containing the
latest Samba source code (usually the branch that is going to be the next major release). This
currently corresponds to the 3.1 development tree.
Subversion branches other then trunk can be obtained by adding branches/BRANCH_NAME to the URL you check out. A list of branch names can be found on the “Development” page of the Samba Web site. A common request is to obtain the latest 3.0 release code. This could be done by using the following command:
svn co svn://svnanon.samba.org/samba/branches/SAMBA_3_0 samba_3.
Whenever you want to merge in the latest code changes, use the following command from within the Samba directory:
pserver.samba.org also exports unpacked copies of most parts of the Subversion tree
at the Samba pserver location and also
via anonymous rsync at the Samba rsync server location. I recommend using rsync rather
than ftp, because rsync is capable of compressing data streams, but it is also more useful than FTP because
during a partial update it will transfer only the data that is missing plus a small overhead. See the rsync home page for more info on rsync.
The disadvantage of the unpacked trees is that they do not support automatic merging of local changes as Subversion does. rsync access is most convenient for an initial install.
It is strongly recommended that you verify the PGP signature for any source file before installing it. Even if you're not downloading from a mirror site, verifying PGP signatures should be a standard reflex. Many people today use the GNU GPG tool set in place of PGP. GPG can substitute for PGP.
With that said, go ahead and download the following files:
gpg --import samba-pubkey.asc
and verify the Samba source code integrity with:
gzip -d samba-3.0.20.tar.gz
gpg --verify samba-3.0.20.tar.asc
If you receive a message like, “Good signature from Samba Distribution Verification Key...,” then all is well. The warnings about trust relationships can be ignored. An example of what you would not want to see would be:
gpg: BAD signature from “Samba Distribution Verification Key”
After the source tarball has been unpacked, the next step involves configuration to match Samba to your operating system platform. If your source directory does not contain the configure script, it is necessary to build it before you can continue. Building of the configure script requires the correct version of the autoconf tool kit. Where the necessary version of autoconf is present, the configure script can be generated by executing the following:
To build the binaries, run the program
in the source directory. This should automatically
configure Samba for your operating system. If you have unusual
needs, then you may wish to first run:
This will help you to see what special options can be enabled. Now execute
./configure with any arguments it might need:
[... arguments ...]
Once it is successfully compiled, you can execute the command shown here to install the binaries and manual pages:
Some people prefer to install binary files and man pages separately. If this is your wish, the binary files can be installed by executing:
The man pages can be installed using this command:
Note that if you are upgrading from a previous version of Samba the old versions of the binaries will be renamed with an “.old” extension. You can go back to the previous version by executing:
As you can see from this, building and installing Samba does not need to result in disaster!
In order to compile Samba with ADS support, you need to have installed on your system:
The MIT or Heimdal Kerberos development libraries (either install from the sources or use a package).
The OpenLDAP development libraries.
If your Kerberos libraries are in a nonstandard location, then
remember to add the configure option
After you run configure, make sure that the
include/config.h it generates contain lines like this:
#define HAVE_KRB5 1 #define HAVE_LDAP 1
If it does not, configure did not find your KRB5 libraries or
your LDAP libraries. Look in
config.log to figure
out why and fix it.
On Debian, you need to install the following packages:
On Red Hat Linux, this means you should have at least:
krb5-workstation (for kinit)
krb5-libs (for linking with)
krb5-devel (because you are compiling from source)
in addition to the standard development environment.
If these files are not installed on your system, you should check the installation CDs to find which has them and install the files using your tool of choice. If in doubt about what tool to use, refer to the Red Hat Linux documentation.
SuSE Linux installs Heimdal packages that may be required to allow you to build binary packages. You should verify that the development libraries have been installed on your system.
SuSE Linux Samba RPMs support Kerberos. Please refer to the documentation for your SuSE Linux system for information regarding SuSE Linux specific configuration. Additionally, SuSE is very active in the maintenance of Samba packages that provide the maximum capabilities that are available. You should consider using SuSE-provided packages where they are available.
You must choose to start smbd, winbindd and nmbd either as daemons or from
inetd. Don't try to do both! Either you can put
inetd.conf and have them started on demand by
inetd or xinetd, or you
can start them as daemons either from the command-line or in
/etc/rc.local. See the man pages for details on the
command line options. Take particular care to read the bit about what user
you need to have to start Samba. In many cases, you must be root.
The main advantage of starting smbd and nmbd using the recommended daemon method is that they will respond slightly more quickly to an initial connection request.
The following will be different if you use NIS, NIS+, or LDAP to distribute services maps.
Look at your
What is defined at port 139/tcp? If nothing is defined,
then add a line like this:
Similarly for 137/udp, you should have an entry like:
Next, edit your
/etc/inetd.conf and add two lines like this:
netbios-ssn stream tcp nowait root /usr/local/samba/sbin/smbd smbd netbios-ns dgram udp wait root /usr/local/samba/sbin/nmbd nmbd
The exact syntax of
varies between UNIXes. Look at the other entries in inetd.conf
for a guide.
Some UNIXes already have entries like netbios_ns
(note the underscore) in
You must edit
/etc/inetd.conf to make them consistent.
On many systems you may need to use the
interfaces option in
smb.conf to specify
the IP address and netmask of your interfaces. Run
ifconfig as root if you do
not know what the broadcast is for your net. nmbd tries
to determine it at runtime, but fails on some UNIXes.
Many UNIXes only accept around five parameters on the command
inetd.conf. This means you shouldn't
use spaces between the options and arguments, or you should use
a script and start the script from inetd.
killall -HUP inetd
#!/bin/sh /usr/local/samba/sbin/smbd -D /usr/local/samba/sbin/winbindd -B /usr/local/samba/sbin/nmbd -D
Make it executable with chmod +x startsmb.
You can then run startsmb by hand or execute
To kill it, send a kill signal to the processes nmbd and smbd.
If you use the SVR4-style init system, you may like to look at the
examples/svr4-startup script to make Samba fit
into that system.
Red Hat Linux has not always included all Samba components in the standard installation. So versions of Red Hat Linux do not install the winbind utility, even though it is present on the installation CDROM media. Check to see if the winbindd is present on the system:
root#ls /usr/sbin/winbindd /usr/sbin/winbindd
This means that the appropriate RPM package was installed. The following response means that it is not installed:
/bin/ls: /usr/sbin/winbind: No such file or directory
In this case, it should be installed if you intend to use winbindd. Search the CDROM installation media for the samba-winbind RPM and install it following Red Hat guidelines.
The process for starting Samba will now be outlined. Be sure to configure Samba's
file before starting Samba. When configured, start Samba by executing:
root#service smb start
root#service winbind start
These steps will start nmbd, smbd and winbindd.
To ensure that these services will be automatically restarted when the system is rebooted execute:
root#chkconfig smb on
root#chkconfig winbind on
Samba will be started automatically at every system reboot.
Novell SUSE Linux products automatically install all essential Samba components in a default installation.
smb.conf file, then execute the following to start Samba:
Now execute these commands so that Samba will be started automatically following a system reboot:
root#chkconfig nmb on
root#chkconfig smb on
root#chkconfig winbind on
The Samba services will now be started automatically following a system reboot.
