</p><p>Prepare your faxheader <tt class="filename">/usr/local/etc/mgetty+sendfax/faxheader</tt></p><p>
Edit your /etc/printcap file:

lp3|fax:\
:lp=/dev/null:\
:sd=/usr/spool/lp3:\
:if=/usr/local/etc/mgetty+sendfax/faxfilter:sh:sf:mx#0:\

Now you have a printer called "fax" which can be used via
TCP/IP-printing (lpd-system) or via SAMBA (windows printing).
</p><p>
On every system you are able to produce postscript-files you
are ready to fax.
</p><p>
On Windows 3.1 95 and NT:
</p><p>
Install a printer wich produces postscript output,
e.g. apple laserwriter
</p><p>Connect the "fax" to your printer.</p><p>
Now write your first fax. Use your favourite wordprocessor,
write, winword, notepad or whatever you want, and start
with the headerpage.
</p><p>
Usually each fax has a header page. It carries your name,
your address, your phone/fax-number.
</p><p>
It carries also the recipient, his address and his *** fax
number ***. Now here is the trick:
</p><p>
Use the text:
</p><pre class="programlisting">
Fax-Nr: 123456789
</pre><p>
as the recipients fax-number. Make sure this text does not
occur in regular text ! Make sure this text is not broken
by formatting information, e.g. format it as a single entity.
(Windows Write and Win95 Wordpad are functional, maybe newer
versions of Winword are breaking formatting information).
</p><p>
The trick is that postscript output is human readable and
the faxfilter program scans the text for this pattern and
uses the found number as the fax-destination-number.
</p><p>
Now print your fax through the fax-printer and it will be
queued for later transmission. Use faxrunq for sending the
queue out.

We wish to help those folks who wish to use the ISC DHCP Server and provide
sample configuration settings. Most operating systems today come ship with
the ISC DHCP Server. ISC DHCP is available from:
<a href="ftp://ftp.isc.org/isc/dhcp" target="_top">ftp://ftp.isc.org/isc/dhcp</a>
</p><p>
Incorrect configuration of MS Windows clients (Windows9X, Windows ME, Windows
NT/2000) will lead to problems with browsing and with general network
operation. Windows 9X/ME users often report problems where the TCP/IP and related
network settings will inadvertantly become reset at machine start-up resulting
in loss of configuration settings. This results in increased maintenance
overheads as well as serious user frustration.
</p><p>
In recent times users on one mailing list incorrectly attributed the cause of
network operating problems to incorrect configuration of Samba.
</p><p>
One user insisted that the only way to provent Windows95 from periodically
performing a full system reset and hardware detection process on start-up was
to install the NetBEUI protocol in addition to TCP/IP. This assertion is not
correct.
</p><p>
In the first place, there is NO need for NetBEUI. All Microsoft Windows clients
natively run NetBIOS over TCP/IP, and that is the only protocol that is
recognised by Samba. Installation of NetBEUI and/or NetBIOS over IPX will
cause problems with browse list operation on most networks. Even Windows NT
networks experience these problems when incorrectly configured Windows95
systems share the same name space. It is important that only those protocols
that are strictly needed for site specific reasons should EVER be installed.
</p><p>
Secondly, and totally against common opinion, DHCP is NOT an evil design but is
an extension of the BOOTP protocol that has been in use in Unix environments
for many years without any of the melt-down problems that some sensationalists
would have us believe can be experienced with DHCP. In fact, DHCP in covered by
rfc1541 and is a very safe method of keeping an MS Windows desktop environment
under control and for ensuring stable network operation.
</p><p>
Please note that MS Windows systems as of MS Windows NT 3.1 and MS Windows 95
store all network configuration settings a registry. There are a few reports
from MS Windows network administrators that warrant mention here. It would appear
that when one sets certain MS TCP/IP protocol settings (either directly or via
DHCP) that these do get written to the registry. Even though a subsequent
change of setting may occur the old value may persist in the registry. This
has been known to create serious networking problems.
</p><p>
An example of this occurs when a manual TCP/IP environment is configured to
include a NetBIOS Scope. In this event, when the administrator then changes the
configuration of the MS TCP/IP protocol stack, without first deleting the
current settings, by simply checking the box to configure the MS TCP/IP stack
via DHCP then the NetBIOS Scope that is still persistent in the registry WILL be
applied to the resulting DHCP offered settings UNLESS the DHCP server also sets
a NetBIOS Scope. It may therefore be prudent to forcibly apply a NULL NetBIOS
Scope from your DHCP server. The can be done in the dhcpd.conf file with the
parameter:
<b class="command">option netbios-scope "";</b>
</p><p>
While it is true that the Microsoft DHCP server that comes with Windows NT
Server provides only a sub-set of rfc1533 functionality this is hardly an issue
in those sites that already have a large investment and commitment to Unix
systems and technologies. The current state of the art of the DHCP Server
specification in covered in rfc2132.
</p></div><div class="sect1" lang="en"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2883112"></a>How can I assign NetBIOS names to clients with DHCP?</h2></div></div><div></div></div><p>
SMB network clients need to be configured so that all standard TCP/IP name to
address resolution works correctly. Once this has been achieved the SMB
environment provides additional tools and services that act as helper agents in
the translation of SMB (NetBIOS) names to their appropriate IP Addresses. One
such helper agent is the NetBIOS Name Server (NBNS) or as Microsoft called it
in their Windows NT Server implementation WINS (Windows Internet Name Server).
</p><p>
A client needs to be configured so that it has a unique Machine (Computer)
Name.
</p><p>
This can be done, but needs a few NT registry hacks and you need to be able to
speak UNICODE, which is of course no problem for a True Wizzard(tm) :)
Instructions on how to do this (including a small util for less capable
Wizzards) can be found at

excellent drag-and-drop cr/lf converter for

</p><p>
The utilities unix2dos and dos2unix(in the mtools package) should do
the job under unix.
