(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

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

></H3
><P
>You can also access the source code via a
normal cvs client. This gives you much more control over 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 http://www.cyclic.com.</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

>The exact syntax of <TT
CLASS="FILENAME"
>/etc/inetd.conf</TT

varies between unixes. Look at the other entries in inetd.conf
for a guide.</P
><P
>NOTE: Some unixes already have entries like netbios_ns
(note the underscore) in <TT

You must either edit <TT
CLASS="FILENAME"
>/etc/services</TT
> or
<TT
CLASS="FILENAME"
>/etc/inetd.conf</TT
> to make them consistent.</P
><P
>NOTE: 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 <B
CLASS="COMMAND"
>ifconfig</B
>
as root if you don't know what the broadcast is for your
net. <B
CLASS="COMMAND"
>nmbd</B
> tries to determine it at run
time, but fails on some unixes. See the section on "testing nmbd"
for a method of finding if you need to do this.</P
><P
>!!!WARNING!!! Many unixes only accept around 5
parameters on the command line in <TT
CLASS="FILENAME"
>inetd.conf</TT
>.
This means you shouldn't use spaces between the options and
arguments, or you should use a script, and start the script
from <B
CLASS="COMMAND"
>inetd</B
>.</P
><P
>Restart <B
CLASS="COMMAND"
>inetd</B
>, perhaps just send
it a HUP. If you have installed an earlier version of <B
