You can obtain the samba source from the
<a href="http://samba.org/" target="_top">samba website</a>. To obtain a development version,
you can download samba from CVS or using rsync.
</p><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id3007789"></a>Access Samba source code via CVS</h2></div></div><div></div></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id3007797"></a>Introduction</h3></div></div><div></div></div><p>
Samba is developed in an open environment. Developers use CVS
(Concurrent Versioning System) to "checkin" (also known as
"commit") new source code. Samba's various CVS branches can
be accessed via anonymous CVS using the instructions
detailed in this chapter.
</p><p>
This chapter is a modified version of the instructions found at
<a href="http://samba.org/samba/cvs.html" target="_top">http://samba.org/samba/cvs.html</a>
</p></div><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id3007826"></a>CVS Access to samba.org</h3></div></div><div></div></div><p>
The machine samba.org runs a publicly accessible CVS
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 CVS server on this host.
</p><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id3007841"></a>Access via CVSweb</h4></div></div><div></div></div><p>
You can access the source code via your
favourite 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.
</p><p>
Use the URL : <a href="http://samba.org/cgi-bin/cvsweb" target="_top">http://samba.org/cgi-bin/cvsweb</a>
</p></div><div class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id3007871"></a>Access via cvs</h4></div></div><div></div></div><p>
You can also access the source code via a
normal cvs client. This gives you much more control over what you can
do with the repository and allows you to checkout whole source trees
and keep them up to date via normal cvs commands. This is the
preferred method of access if you are a developer and not
just a casual browser.
</p><p>
To download the latest cvs source code, point your
browser at the URL :
<a href="http://www.cyclic.com/" target="_top">http://www.cyclic.com/</a>.
and click on the 'How to get cvs' link. CVS is free software under
the GNU GPL (as is Samba). Note that there are several graphical CVS clients
which provide a graphical interface to the sometimes mundane CVS commands.
Links to theses clients are also available from the Cyclic website.
</p><p>
To gain access via anonymous cvs use the following steps.
For this example it is assumed that you want a copy of the
samba source code. For the other source code repositories
on this system just substitute the correct package name
</p><div class="procedure"><p class="title"><b>Procedure 36.1. Retrieving samba using CVS</b></p><ol type="1"><li><p>
Install a recent copy of cvs. All you really need is a
copy of the cvs client binary.
</p></li><li><p>
Run the command
</p><p>
<b class="userinput"><tt>cvs -d :pserver:cvs@samba.org:/cvsroot login</tt></b>
</p></li><li><p>
When it asks you for a password type <b class="userinput"><tt>cvs</tt></b>.
</p></li><li><p>
Run the command
</p><p>
<b class="userinput"><tt>cvs -d :pserver:cvs@samba.org:/cvsroot co samba</tt></b>
</p><p>
This will create a directory called samba containing the
latest samba source code (i.e. the HEAD tagged cvs branch). This
currently corresponds to the 3.0 development tree.
</p><p>
CVS branches other then HEAD can be obtained by using the
<tt class="option">-r</tt> and defining a tag name. A list of branch tag 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 userinput.
</p><p>
<b class="userinput"><tt>cvs -d :pserver:cvs@samba.org:/cvsroot co -r SAMBA_3_0 samba</tt></b>
</p></li><li><p>
Whenever you want to merge in the latest code changes use
the following command from within the samba directory:
</p><p>
<b class="userinput"><tt>cvs update -d -P</tt></b>
</p></li></ol></div></div></div></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id3009294"></a>Accessing the samba sources via rsync and ftp</h2></div></div><div></div></div><p>
pserver.samba.org also exports unpacked copies of most parts of the CVS
tree at <a href="ftp://pserver.samba.org/pub/unpacked" target="_top">ftp://pserver.samba.org/pub/unpacked</a> and also via anonymous rsync at
<a href="rsync://pserver.samba.org/ftp/unpacked/" target="_top">rsync://pserver.samba.org/ftp/unpacked/</a>. I recommend using rsync rather than ftp.
See <a href="http://rsync.samba.org/" target="_top">the rsync homepage</a> for more info on rsync.
</p><p>
The disadvantage of the unpacked trees is that they do not support automatic
merging of local changes like CVS does. rsync access is most convenient
for an initial install.
</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id3009342"></a>Verifying Samba's PGP signature</h2></div></div><div></div></div><p>
In these days of insecurity, it's 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.
</p><p>
With that said, go ahead and download the following files:
</p><pre class="screen">
<tt class="prompt">$ </tt><b class="userinput"><tt> wget http://us1.samba.org/samba/ftp/samba-2.2.8a.tar.asc</tt></b>
<tt class="prompt">$ </tt><b class="userinput"><tt> wget http://us1.samba.org/samba/ftp/samba-pubkey.asc</tt></b>
</pre><p>
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:
</p><pre class="screen">
<tt class="prompt">$ </tt><b class="userinput"><tt>gpg --import samba-pubkey.asc</tt></b>
</pre><p>
And verify the Samba source code integrity with:
</p><pre class="screen">
<tt class="prompt">$ </tt><b class="userinput"><tt>gzip -d samba-2.2.8a.tar.gz</tt></b>
<tt class="prompt">$ </tt><b class="userinput"><tt>gpg --verify samba-2.2.8a.tar.asc</tt></b>
</pre><p>
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:
</p><tt class="computeroutput">
gpg: BAD signature from "Samba Distribution Verification Key"
</tt></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id3009477"></a>Building the Binaries</h2></div></div><div></div></div><p>To do this, first run the program <b class="userinput"><tt>./configure
</tt></b> in the source directory. This should automatically
configure Samba for your operating system. If you have unusual
needs then you may wish to run</p><p><tt class="prompt">root# </tt><b class="userinput"><tt>./configure --help
</tt></b></p><p>first to see what special options you can enable.
Then executing</p><p><tt class="prompt">root# </tt><b class="userinput"><tt>make</tt></b></p><p>will create the binaries. Once it's successfully
compiled you can use </p><p><tt class="prompt">root# </tt><b class="userinput"><tt>make install</tt></b></p><p>to install the binaries and manual pages. You can
separately install the binaries and/or man pages using</p><p><tt class="prompt">root# </tt><b class="userinput"><tt>make installbin
</tt></b></p><p>and</p><p><tt class="prompt">root# </tt><b class="userinput"><tt>make installman
</tt></b></p><p>Note that if you are upgrading for a previous version
of Samba you might like to know that the old versions of
the binaries will be renamed with a ".old" extension. You
can go back to the previous version with</p><p><tt class="prompt">root# </tt><b class="userinput"><tt>make revert
</tt></b></p><p>if you find this version a disaster!</p><div class="sect2" lang="en"><div class="titlepage"><div><div><h3 class="title"><a name="id3009615"></a>Compiling samba with Active Directory support</h3></div></div><div></div></div><p>In order to compile samba with ADS support, you need to have installed
on your system:</p><div class="itemizedlist"><ul type="disc"><li><p>the MIT kerberos development libraries
(either install from the sources or use a package). The
heimdal libraries will not work.</p></li><li><p>the OpenLDAP development libraries.</p></li></ul></div><p>If your kerberos libraries are in a non-standard location then
remember to add the configure option
<tt class="option">--with-krb5=<i class="replaceable"><tt>DIR</tt></i></tt>.</p><p>After you run configure make sure that
<tt class="filename">include/config.h</tt> it generates contains lines like
this:</p><pre class="programlisting">
#define HAVE_KRB5 1
#define HAVE_LDAP 1
</pre><p>If it doesn't then configure did not find your krb5 libraries or
your ldap libraries. Look in <tt class="filename">config.log</tt> to figure
out why and fix it.</p><div xmlns:ns99="" class="sect3" lang="en"><div class="titlepage"><div><div><h4 class="title"><a name="id3010424"></a>Installing the required packages for Debian</h4></div></div><div></div></div><p>On Debian you need to install the following packages:</p><ns99:p>
