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.

Access Samba Source Code via GIT

Introduction

Samba is developed in an open environment. Developers use GIT to checkin (also known as commit) new source code. See the Using Git for Samba Development page in the Samba wiki.

Accessing the Samba Sources via rsync and ftp

pserver.samba.org also exports unpacked copies of most parts of the Subversion tree at the Samba unpacked 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 GIT does. rsync access is most convenient for an initial install.

Verifying Samba's PGP Signature

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:

$ wget https://www.samba.org/samba/ftp/samba-latest.tar.asc
$ wget https://www.samba.org/samba/ftp/samba-latest.tar.gz
$ wget https://www.samba.org/samba/ftp/samba-pubkey.asc

The first file is the PGP signature for the Samba source file; the other is the Samba public PGP key itself. Import the public PGP key with:

$ gpg --import samba-pubkey.asc

and verify the Samba source code integrity with:

$ gzip -d samba-latest.tar.gz
$ gpg --verify samba-latest.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

Building the Binaries

To build the binaries, run the program ./configure in the top level directory of the source tree. This should automatically configure Samba for your operating system. If you have unusual needs, then you may wish to first run:

root# ./configure --help

This will help you to see what special options can be enabled. Now execute ./configure with any arguments it might need:

root# ./configure [... arguments ...]

Execute the following create the binaries:

root#  make

Once it is successfully compiled, you can execute the command shown here to install the binaries and manual pages:

root#  make install

Compiling Samba with Active Directory Support

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 --with-krb5=DIR.

After you run configure, make sure that the bin/default/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 bin/config.log to figure out why and fix it.

Installing the Required Packages for Debian

On Debian, you need to install the following packages:

  • libkrb5-dev

  • krb5-user

Installing the Required Packages for Red Hat Linux

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 Package Requirements

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.

Starting the smbd nmbd and winbindd

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 them in 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.

Starting smbd as a Daemon

To start the server as a daemon, you should create a script something like this one, perhaps calling it startsmb.

#!/bin/sh
/usr/local/samba/sbin/smbd -D
/usr/local/samba/sbin/winbindd -D
/usr/local/samba/sbin/nmbd -D

Make it executable with chmod +x startsmb.

You can then run startsmb by hand or execute it from /etc/rc.local.

To kill it, send a kill signal to the processes nmbd and smbd.

Note

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.

Starting Samba for Red Hat Linux

The process for starting Samba will now be outlined. Be sure to configure Samba's smb.conf 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.

Starting Samba for Novell SUSE Linux

Novell SUSE Linux products automatically install all essential Samba components in a default installation. Configure your smb.conf file, then execute the following to start Samba:

root#  rcnmb start
root#  rcsmb start
root#  rcwinbind start

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.
