swat - Samba Web Administration Tool
swat [ -s <smb config file> ] [ -a ]
This tool is part of the Samba suite.
swat allows a Samba administrator to configure the complex smb.conf(5) file via a Web
browser. In addition, a swat configuration page has help links to all the configurable
options in the smb.conf file allowing an administrator to easily look up the effects of
swat is run from inetd
-s smb configuration file
The default configuration file path is determined at compile time. The file speci-
fied contains the configuration details required by the smbd server. This is the
file that swat will modify. The information in this file includes server-specific
information such as what printcap file to use, as well as descriptions of all the
services that the server is to provide. See smb.conf for more information.
-a This option disables authentication and puts swat in demo mode. In that mode anyone
will be able to modify the smb.conf file.
Do NOT enable this option on a production server.
After you compile SWAT you need to run make install to install the swat binary and the
various help files and images. A default install would put these in:
You need to edit your /etc/inetd.conf and /etc/services to enable SWAT to be launched via
In /etc/services you need to add a line like this:
Note for NIS/YP users - you may need to rebuild the NIS service maps rather than alter
your local /etc/services file.
the choice of port number isn't really important except that it should be less than 1024
and not currently used (using a number above 1024 presents an obscure security hole
depending on the implementation details of your inetd daemon).
In /etc/inetd.conf you should add a line like this:
swat stream tcp nowait.400 root /usr/local/samba/bin/swat swat
One you have edited /etc/services and /etc/inetd.conf you need to send a HUP signal to
inetd. To do this use kill -1 PID where PID is the process ID of the inetd daemon.
Newer Linux systems ship with a more secure implementation of the inetd meta-daemon. The
xinetd daemon can read configuration inf9ormation from a single file (i.e.
/etc/xinetd.conf) or from a collection of service control files in the xinetd.d/ direc-
tory. These directions assume the latter configuration.
The following file should be created as /etc/xientd.d/swat. It is then be neccessary
cause the meta-daemon to reload its configuration files. Refer to the xinetd man page for
details on how to accomplish this.
port = 901
socket_type = stream
wait = no
only_from = localhost
user = root
server = /usr/local/samba/bin/swat
log_on_failure += USERID
disable = No
To launch SWAT just run your favorite web browser and point it at "http://localhost:901/".
Note that you can attach to SWAT from any IP connected machine but connecting from a
remote machine leaves your connection open to password sniffing as passwords will be sent
in the clear over the wire.
One of the common causes of difficulty when installing Samba and SWAT is the existsnece of
some type of firewall or port filtering software on the Samba server. Make sure that the
appropriate ports outlined in this man page are available on the server and are not cur-
rently being blocked by some type of security software such as iptables or "port sentry".
For more troubleshooting information, refer to the additional documentation included in
the Samba distribution.
This file must contain suitable startup information for the meta-daemon.
This file must contain suitable startup information for the xinetd meta-daemon.
This file must contain a mapping of service name (e.g., swat) to service port
(e.g., 901) and protocol type (e.g., tcp).
This is the default location of the smb.conf(5) server configuration file that swat
edits. Other common places that systems install this file are
/usr/samba/lib/smb.conf and /etc/smb.conf . This file describes all the services
the server is to make available to clients.
swat will rewrite your smb.conf file. It will rearrange the entries and delete all com-
ments, include= and copy=" options. If you have a carefully crafted smb.conf then back it
up or don't use swat!

The original Samba software and related utilities were created by Andrew Tridgell. Samba
is now developed by the Samba Team as an Open Source project similar to the way the Linux
kernel is developed.
The original Samba man pages were written by Karl Auer. The man page sources were con-
verted to YODL format (another excellent piece of Open Source software, available at
ftp://ftp.icce.rug.nl/pub/unix/ <URL:ftp://ftp.icce.rug.nl/pub/unix/>) and updated for the
Samba 2.0 release by Jeremy Allison. The conversion to DocBook for Samba 2.2 was done by
19 November 2002 SWAT(8)
