the bit about what user you need to be in order to start

What is defined at port 139/tcp. If nothing is defined
then add a line like this:</P
><P
><TT
CLASS="USERINPUT"

>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
CLASS="FILENAME"

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
CLASS="COMMAND"
> nmbd</B

>Choosing the Protocol Level</A
></H2
><P
>The SMB protocol has many dialects. Currently
Samba supports 5, called CORE, COREPLUS, LANMAN1,
LANMAN2 and NT1.</P
><P
>You can choose what maximum protocol to support
in the <TT
CLASS="FILENAME"
>smb.conf</TT
> file. The default is
NT1 and that is the best for the vast majority of sites.</P
><P
>In older versions of Samba you may have found it
necessary to use COREPLUS. The limitations that led to
this have mostly been fixed. It is now less likely that you
will want to use less than LANMAN1. The only remaining advantage
of COREPLUS is that for some obscure reason WfWg preserves
the case of passwords in this protocol, whereas under LANMAN1,
LANMAN2 or NT1 it uppercases all passwords before sending them,
forcing you to use the "password level=" option in some cases.</P
><P
>The main advantage of LANMAN2 and NT1 is support for
long filenames with some clients (eg: smbclient, Windows NT
or Win95). </P
><P
>See the smb.conf(5) manual page for more details.</P
><P
>Note: To support print queue reporting you may find
that you have to use TCP/IP as the default protocol under
WfWg. For some reason if you leave Netbeui as the default
it may break the print queue reporting on some systems.
It is presumably a WfWg bug.</P

>Locking</A
></H2
><P
>One area which sometimes causes trouble is locking.</P
><P
>There are two types of locking which need to be
performed by a SMB server. The first is "record locking"
which allows a client to lock a range of bytes in a open file.
The second is the "deny modes" that are specified when a file
is open.</P
><P
>Record locking semantics under Unix is very
different from record locking under Windows. Versions
of Samba before 2.2 have tried to use the native
fcntl() unix system call to implement proper record
locking between different Samba clients. This can not
be fully correct due to several reasons. The simplest
is the fact that a Windows client is allowed to lock a
byte range up to 2^32 or 2^64, depending on the client
OS. The unix locking only supports byte ranges up to
2^31. So it is not possible to correctly satisfy a
lock request above 2^31. There are many more
differences, too many to be listed here.</P
><P
>Samba 2.2 and above implements record locking
completely independent of the underlying unix
system. If a byte range lock that the client requests
happens to fall into the range 0-2^31, Samba hands
this request down to the Unix system. All other locks
can not be seen by unix anyway.</P
><P
>Strictly a SMB server should check for locks before
every read and write call on a file. Unfortunately with the
way fcntl() works this can be slow and may overstress the
rpc.lockd. It is also almost always unnecessary as clients
are supposed to independently make locking calls before reads
and writes anyway if locking is important to them. By default
Samba only makes locking calls when explicitly asked
to by a client, but if you set "strict locking = yes" then it will
make lock checking calls on every read and write. </P
><P
>You can also disable by range locking completely
using "locking = no". This is useful for those shares that
don't support locking or don't need it (such as cdroms). In
this case Samba fakes the return codes of locking calls to
tell clients that everything is OK.</P
><P
>The second class of locking is the "deny modes". These
are set by an application when it opens a file to determine
what types of access should be allowed simultaneously with
its open. A client may ask for DENY_NONE, DENY_READ, DENY_WRITE
or DENY_ALL. There are also special compatibility modes called
DENY_FCB and DENY_DOS.</P
