<title>Samba and other CIFS clients</title>
<para>This chapter contains client-specific information.</para>
<sect1>
<title>Macintosh clients?</title>
<para>
Yes. <ulink url="http://www.thursby.com/">Thursby</ulink> now has a CIFS Client / Server called <ulink url="http://www.thursby.com/products/dave.html">DAVE</ulink>
</para>
<para>
They test it against Windows 95, Windows NT and samba for
compatibility issues. At the time of writing, DAVE was at version
1.0.1. The 1.0.0 to 1.0.1 update is available as a free download from
the Thursby web site (the speed of finder copies has been greatly
enhanced, and there are bug-fixes included).
</para>
<para>
Alternatives - There are two free implementations of AppleTalk for
several kinds of UNIX machines, and several more commercial ones.
These products allow you to run file services and print services
natively to Macintosh users, with no additional support required on
the Macintosh. The two free implementations are
<ulink url="http://www.umich.edu/~rsug/netatalk/">Netatalk</ulink>, and
<ulink url="http://www.cs.mu.oz.au/appletalk/atalk.html">CAP</ulink>.
What Samba offers MS
Windows users, these packages offer to Macs. For more info on these

<title>OS2 Client</title>
<sect2>
<title>Configuring OS/2 Warp Connect or
OS/2 Warp 4 as a client for Samba</title>
<para>Basically, you need three components:</para>
<itemizedlist>
<listitem><para>The File and Print Client ('IBM Peer')</para></listitem>
<listitem><para>TCP/IP ('Internet support') </para></listitem>
<listitem><para>The "NetBIOS over TCP/IP" driver ('TCPBEUI')</para></listitem>
</itemizedlist>
<para>Installing the first two together with the base operating
system on a blank system is explained in the Warp manual. If Warp
has already been installed, but you now want to install the
networking support, use the "Selective Install for Networking"
object in the "System Setup" folder.</para>
<para>Adding the "NetBIOS over TCP/IP" driver is not described
in the manual and just barely in the online documentation. Start
MPTS.EXE, click on OK, click on "Configure LAPS" and click
on "IBM OS/2 NETBIOS OVER TCP/IP" in 'Protocols'. This line
is then moved to 'Current Configuration'. Select that line,
click on "Change number" and increase it from 0 to 1. Save this
configuration.</para>
<para>If the Samba server(s) is not on your local subnet, you
can optionally add IP names and addresses of these servers
to the "Names List", or specify a WINS server ('NetBIOS
Nameserver' in IBM and RFC terminology). For Warp Connect you
may need to download an update for 'IBM Peer' to bring it on
the same level as Warp 4. See the webpage mentioned above.</para>
</sect2>
<sect2>
<title>Configuring OS/2 Warp 3 (not Connect),
OS/2 1.2, 1.3 or 2.x for Samba</title>
<para>You can use the free Microsoft LAN Manager 2.2c Client
for OS/2 from
<ulink noescape="1" url="ftp://ftp.microsoft.com/BusSys/Clients/LANMAN.OS2/">
ftp://ftp.microsoft.com/BusSys/Clients/LANMAN.OS2/</ulink>.
In
a nutshell, edit the file \OS2VER in the root directory of
the OS/2 boot partition and add the lines:</para>
<para><programlisting>
20=setup.exe
20=netwksta.sys
20=netvdd.sys
</programlisting></para>
<para>before you install the client. Also, don't use the
included NE2000 driver because it is buggy. Try the NE2000
or NS2000 driver from
<ulink noescape="1" url="ftp://ftp.cdrom.com/pub/os2/network/ndis/">
ftp://ftp.cdrom.com/pub/os2/network/ndis/</ulink> instead.

<title>Printer driver download for for OS/2 clients?</title>
<para>First, create a share called <smbconfsection>[PRINTDRV]</smbconfsection> that is
world-readable. Copy your OS/2 driver files there. Note
that the .EA_ files must still be separate, so you will need
to use the original install files, and not copy an installed
driver from an OS/2 system.</para>
<para>Install the NT driver first for that printer. Then,
add to your &smb.conf; a parameter, <smbconfoption><name>os2 driver map</name><value><replaceable>filename</replaceable></value></smbconfoption>. Then, in the file
specified by <replaceable>filename</replaceable>, map the
name of the NT driver name to the OS/2 driver name as
follows:</para>
<para><parameter><replaceable>nt driver name</replaceable> = <replaceable>os2 driver name</replaceable>.<replaceable>device name</replaceable></parameter>, e.g.:</para>
<para><parameter>
HP LaserJet 5L = LASERJET.HP LaserJet 5L</parameter></para>
<para>You can have multiple drivers mapped in this file.</para>
<para>If you only specify the OS/2 driver name, and not the
device name, the first attempt to download the driver will
actually download the files, but the OS/2 client will tell
you the driver is not available. On the second attempt, it
will work. This is fixed simply by adding the device name
to the mapping, after which it will work on the first attempt.

<title>Latest TCP/IP stack from Microsoft</title>
<para>Use the latest TCP/IP stack from Microsoft if you use Windows
for Workgroups.
</para>
<para>The early TCP/IP stacks had lots of bugs.</para>
<para>
Microsoft has released an incremental upgrade to their TCP/IP 32-Bit
VxD drivers. The latest release can be found on their ftp site at
ftp.microsoft.com, located in <filename>/peropsys/windows/public/tcpip/wfwt32.exe</filename>.
There is an update.txt file there that describes the problems that were
fixed. New files include <filename>WINSOCK.DLL</filename>,
<filename>TELNET.EXE</filename>,
<filename>WSOCK.386</filename>,
<filename>VNBT.386</filename>,
<filename>WSTCP.386</filename>,
<filename>TRACERT.EXE</filename>,

<title>Delete .pwl files after password change</title>
<para>
WfWg does a lousy job with passwords. I find that if I change my
password on either the unix box or the PC the safest thing to do is to
delete the .pwl files in the windows directory. The PC will complain about not finding the files, but will soon get over it, allowing you to enter the new password.
</para>
<para>
If you don't do this you may find that WfWg remembers and uses the old
password, even if you told it a new one.
</para>
<para>
Often WfWg will totally ignore a password you give it in a dialog box.
</para>
</sect2>
<sect2>
<title>Configuring WfW password handling</title>
<para>
There is a program call admincfg.exe
on the last disk (disk 8) of the WFW 3.11 disk set. To install it
type <userinput>EXPAND A:\ADMINCFG.EX_ C:\WINDOWS\ADMINCFG.EXE</userinput>.
Then add an icon
for it via the <application>Program Manager</application> <guimenu>New</guimenu> Menu.
This program allows you to control how WFW handles passwords. ie disable Password Caching etc
for use with <smbconfoption><name>security</name><value>user</value></smbconfoption>
</para>
</sect2>
<sect2>
<title>Case handling of passwords</title>
<para>Windows for Workgroups uppercases the password before sending it to the server. Unix passwords can be case-sensitive though. Check the &smb.conf; information on <smbconfoption><name>password level</name></smbconfoption> to specify what characters samba should try to uppercase when checking.</para>
</sect2>
<sect2>
<title>Use TCP/IP as default protocol</title>
<para>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.</para>
</sect2>
<sect2>
<title>Speed improvement</title>
<para>
Note that some people have found that setting <parameter>DefaultRcvWindow</parameter> in
the <smbconfsection>[MSTCP]</smbconfsection> section of the
<filename>SYSTEM.INI</filename> file under WfWg to 3072 gives a
big improvement. I don't know why.
</para>
<para>
My own experience with DefaultRcvWindow is that I get much better
performance with a large value (16384 or larger). Other people have
reported that anything over 3072 slows things down enormously. One
person even reported a speed drop of a factor of 30 when he went from
3072 to 8192. I don't know why.

<title>Windows '95/'98</title>
<para>
When using Windows 95 OEM SR2 the following updates are recommended where Samba
is being used. Please NOTE that the above change will affect you once these
updates have been installed.
</para>
<para>
There are more updates than the ones mentioned here. You are referred to the
Microsoft Web site for all currently available updates to your specific version
of Windows 95.

<member>Ping Fix: PINGUPD.EXE</member>
<member>RPC Update: RPCRTUPD.EXE</member>
<member>TCP/IP Update: VIPUPD.EXE</member>
<member>Redirector Update: VRDRUPD.EXE</member>
</simplelist>
<para>
Also, if using <application>MS Outlook</application> it is desirable to
install the <command>OLEUPD.EXE</command> fix. This
fix may stop your machine from hanging for an extended period when exiting
Outlook and you may also notice a significant speedup when accessing network
neighborhood services.
</para>
<sect2>
<title>Speed improvement</title>
<para>
Configure the win95 TCPIP registry settings to give better
performance. I use a program called <command>MTUSPEED.exe</command> which I got off the
net. There are various other utilities of this type freely available.

<title>Windows 2000 Service Pack 2</title>
<para>
There are several annoyances with Windows 2000 SP2. One of which
only appears when using a Samba server to host user profiles
to Windows 2000 SP2 clients in a Windows domain. This assumes
that Samba is a member of the domain, but the problem will
likely occur if it is not.
</para>
<para>
In order to serve profiles successfully to Windows 2000 SP2
clients (when not operating as a PDC), Samba must have
<smbconfoption><name>nt acl support</name><value>no</value></smbconfoption>
added to the file share which houses the roaming profiles.
If this is not done, then the Windows 2000 SP2 client will
complain about not being able to access the profile (Access
Denied) and create multiple copies of it on disk (DOMAIN.user.001,
DOMAIN.user.002, etc...). See the
&smb.conf; man page
for more details on this option. Also note that the
<smbconfoption><name>nt acl support</name></smbconfoption> parameter was formally a global parameter in
releases prior to Samba 2.2.2.
</para>
<para>
The following is a minimal profile share:
</para>
<para><smbconfexample>
<title>Minimal profile share</title>
<smbconfsection>[profile]</smbconfsection>
<smbconfoption><name>path</name><value>/export/profile</value></smbconfoption>
<smbconfoption><name>create mask</name><value>0600</value></smbconfoption>
<smbconfoption><name>directory mask</name><value>0700</value></smbconfoption>
<smbconfoption><name>nt acl support</name><value>no</value></smbconfoption>
<smbconfoption><name>read only</name><value>no</value></smbconfoption>
</smbconfexample></para>
<para>
The reason for this bug is that the Win2k SP2 client copies
the security descriptor for the profile which contains
the Samba server's SID, and not the domain SID. The client
compares the SID for SAMBA\user and realizes it is
different that the one assigned to DOMAIN\user. Hence the reason
for the <errorname>access denied</errorname> message.
</para>
<para>
By disabling the <smbconfoption><name>nt acl support</name></smbconfoption> parameter, Samba will send
the Win2k client a response to the QuerySecurityDescriptor
trans2 call which causes the client to set a default ACL
for the profile. This default ACL includes

create accounts on the Samba host for Domain users.</para></note>
