>The file consists of sections and parameters. A section
begins with the name of the section in square brackets and continues
until the next section begins. Sections contain parameters of the
form</P

>Only the first equals sign in a parameter is significant.
Whitespace before or after the first equals sign is discarded.
Leading, trailing and internal whitespace in section and parameter
names is irrelevant. Leading and trailing whitespace in a parameter
value is discarded. Internal whitespace within a parameter value
is retained verbatim.</P

>The values following the equals sign in parameters are all
either a string (no quotes needed) or a boolean, which may be given
as yes/no, 0/1 or true/false. Case is not significant in boolean
values, but is preserved in string values. Some items such as
create modes are numeric.</P

>SECTION DESCRIPTIONS</H2
><P
>Each section in the configuration file (except for the
[global] section) describes a shared resource (known
as a "share"). The section name is the name of the
shared resource and the parameters within the section define
the shares attributes.</P
><P
>There are three special sections, [global],
[homes] and [printers], which are
described under <EM
>special sections</EM
>. The
following notes apply to ordinary section descriptions.</P
><P
>A share consists of a directory to which access is being
given plus a description of the access rights which are granted
to the user of the service. Some housekeeping options are
also specifiable.</P
><P
>Sections are either file share services (used by the
client as an extension of their native file systems) or
printable services (used by the client to access print services
on the host running the server).</P
><P
>Sections may be designated <EM
>guest</EM
> services,
in which case no password is required to access them. A specified
UNIX <EM
>guest account</EM
> is used to define access
privileges in this case.</P
><P
>Sections other than guest services will require a password
to access them. The client provides the username. As older clients
only provide passwords and not usernames, you may specify a list
of usernames to check against the password using the "user="
option in the share definition. For modern clients such as
Windows 95/98/ME/NT/2000, this should not be necessary.</P
><P
>Note that the access rights granted by the server are
masked by the access rights granted to the specified or guest
UNIX user by the host system. The server does not grant more
access than the host system grants.</P
><P
>The following sample section defines a file space share.
The user has write access to the path <TT
CLASS="FILENAME"
>/home/bar</TT
>.
The share is accessed via the share name "foo":</P

The share is readonly, but printable. That is, the only write
access permitted is via calls to open, write to and close a
spool file. The <EM

access will be permitted as the default guest user (specified
elsewhere):</P

specifically define certain items. See the notes
under PARAMETERS for more information.</P

><H3
>The [homes] section</H3
><P
>If a section called homes is included in the
configuration file, services connecting clients to their
home directories can be created on the fly by the server.</P
><P
>When the connection request is made, the existing
sections are scanned. If a match is found, it is used. If no
match is found, the requested section name is treated as a
user name and looked up in the local password file. If the
name exists and the correct password has been given, a share is
created by cloning the [homes] section.</P
><P
>Some modifications are then made to the newly
created share:</P
><P
></P
><UL
><LI
><P
>The share name is changed from homes to
the located username.</P
></LI
><LI
><P
>If no path was given, the path is set to
the user's home directory.</P
></LI
></UL
><P
>If you decide to use a <EM
>path=</EM
> line
in your [homes] section then you may find it useful
to use the %S macro. For example :</P
><P
><TT
CLASS="USERINPUT"
><B
>path=/data/pchome/%S</B
></TT
></P
><P
>would be useful if you have different home directories
for your PCs than for UNIX access.</P
><P
>This is a fast and simple way to give a large number
of clients access to their home directories with a minimum
of fuss.</P
><P
>A similar process occurs if the requested section
name is "homes", except that the share name is not
changed to that of the requesting user. This method of using
the [homes] section works well if different users share
a client PC.</P
><P
>The [homes] section can specify all the parameters
a normal service section can specify, though some make more sense
than others. The following is a typical and suitable [homes]
section:</P

></TABLE
><P
>An important point is that if guest access is specified
in the [homes] section, all home directories will be
visible to all clients <EM
>without a password</EM
>.
In the very unlikely event that this is actually desirable, it
would be wise to also specify <EM
>read only
access</EM
>.</P
><P
>Note that the <EM
>browseable</EM
> flag for
auto home directories will be inherited from the global browseable
flag, not the [homes] browseable flag. This is useful as
it means setting browseable=no in the [homes] section
will hide the [homes] share but make any auto home
directories visible.</P
></DIV
><DIV
CLASS="REFSECT2"
><A
NAME="AEN78"
></A
><H3
>The [printers] section</H3
><P
>This section works like [homes],
but for printers.</P
><P
>If a [printers] section occurs in the
configuration file, users are able to connect to any printer
specified in the local host's printcap file.</P
><P
>When a connection request is made, the existing sections
are scanned. If a match is found, it is used. If no match is found,
but a [homes] section exists, it is used as described
above. Otherwise, the requested section name is treated as a
printer name and the appropriate printcap file is scanned to see
if the requested section name is a valid printer share name. If
a match is found, a new printer share is created by cloning
the [printers] section.</P
><P
>A few modifications are then made to the newly created
share:</P
><P
></P
><UL
><LI
><P
>The share name is set to the located printer
name</P
></LI
><LI
><P
>If no printer name was given, the printer name
is set to the located printer name</P
></LI
><LI
><P
>If the share does not permit guest access and
no username was given, the username is set to the located
printer name.</P
></LI
></UL
><P
>Note that the [printers] service MUST be
printable - if you specify otherwise, the server will refuse
to load the configuration file.</P
><P
>Typically the path specified would be that of a
world-writeable spool directory with the sticky bit set on
it. A typical [printers] entry would look like
this:</P
><TABLE

</TT
></PRE
></TD
></TR
></TABLE
><P
>All aliases given for a printer in the printcap file
are legitimate printer names as far as the server is concerned.
If your printing subsystem doesn't work like that, you will have
to set up a pseudo-printcap. This is a file consisting of one or
more lines like this:</P
><TABLE
BORDER="0"
BGCOLOR="#E0E0E0"
WIDTH="100%"
><TR
><TD
><PRE
CLASS="SCREEN"
> <TT
CLASS="COMPUTEROUTPUT"
> alias|alias|alias|alias...
</TT
>
</PRE
></TD
></TR
></TABLE
><P
>Each alias should be an acceptable printer name for
your printing subsystem. In the [global] section, specify
the new file as your printcap. The server will then only recognize
names found in your pseudo-printcap, which of course can contain
whatever aliases you like. The same technique could be used
simply to limit access to a subset of your local printers.</P
><P
>An alias, by the way, is defined as any component of the
first entry of a printcap record. Records are separated by newlines,
components (if there are more than one) are separated by vertical
bar symbols ('|').</P
><P
>NOTE: On SYSV systems which use lpstat to determine what
printers are defined on the system you may be able to use
"printcap name = lpstat" to automatically obtain a list
of printers. See the "printcap name" option
for more details.</P

><H2
>PARAMETERS</H2

(e.g., <EM

in all sections (e.g., <EM
>create mode</EM
>). All others
are permissible only in normal sections. For the purposes of the
following descriptions the [homes] and [printers]
sections will be considered normal. The letter <EM
>G</EM
>
in parentheses indicates that a parameter is specific to the
[global] section. The letter <EM
>S</EM
>
indicates that a parameter can be specified in a service specific
section. Note that all <EM

the [global] section - in which case they will define
the default behavior for all services.</P

not create best bedfellows, but at least you can find them! Where
there are synonyms, the preferred synonym is described, others refer
