Abstract

This book is a collection of HOWTOs added to Samba documentation over the years. I try to ensure that all

are current, but sometimes the is a larger job than one person can maintain. The most recent version of this

document can be found at http://www.samba.org/ on the "Documentation" page. Please send updates to

jerry@samba.org .

Chapter 1. How to Install and Test SAMBA

1.1. Step 0: Read the man pages

The man pages distributed with SAMBA contain lots of useful info that will help to get you started. If you

don't know how to read man pages then try something like:

$ nroff −man smbd.8 | more

Other sources of information are pointed to by the Samba web site, http://www.samba.org

1.2. Step 1: Building the Binaries

To do this, first run the program ./configure in the source directory. This should automatically configure

Samba for your operating system. If you have unusual needs then you may wish to run

root# ./configure −−help

first to see what special options you can enable. Then exectuting

root# make

will create the binaries. Once it's successfully compiled you can use

root# make install

to install the binaries and manual pages. You can separately install the binaries and/or man pages using

root# make installbin

and

root# make installman

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

root# make revert

if you find this version a disaster!

1.3. Step 2: The all important step

At this stage you must fetch yourself a coffee or other drink you find stimulating. Getting the rest of the

install right can sometimes be tricky, so you will probably need it.

If you have installed samba before then you can skip this step.
