This text describes how to turn your SAMBA-server into a fax-server
for any environment, especially for Windows.
UNIX box (Linux preferred) with SAMBA and a faxmodem
pbm package (portable bitmap tools)
mgetty099-May31.tar.gz is newest version
I got it from: ftp://ftp.gwdg.de/pub/linux/misc/mgetty/mgetty099-May31.tar.gz
making mgetty+sendfax running:
go to source tree: /usr/src/mgetty+sendfax
cp policy.h-dist policy.h
change your settings: valid tty ports, modem initstring, Station-Id
#define MODEM_INIT_STRING "AT &F S0=0 &D3 &K3 &C1\\\\N2"
#define FAX_STATION_ID "49 30 12345678"
#define FAX_MODEM_TTYS "ttyS1:ttyS2:ttyS3"
Modem initstring is for rockwell based modems
if you want to use mgetty+sendfax as PPP-dialin-server,
define AUTO_PPP in Makefile:
CFLAGS=-O2 -Wall -pipe -DAUTO_PPP
compile it and install the package.
edit your /etc/inittab and let mgetty running on your preferred
s3:45:respawn:/usr/local/sbin/mgetty ttyS2 vt100
now issue a
kill -HUP 1
and enjoy with the lightning LEDs on your modem
your now are ready to receive faxes !
if you want a PPP dialin-server, edit
/AutoPPP/ - ppp /usr/sbin/pppd auth debug passive modem
Note: this package automatically decides between a fax call and
a modem call. In case of modem call you get a login prompt !
Tools for printing faxes:
your incomed faxes are in:
print it with:
for i in *
g3cat $i | g3tolj | lpr -P hp
in case of low resolution use instead:
g3cat $i | g3tolj -aspect 2 | lpr -P hp
g3cat is in the tools-section, g3tolj is in the contrib-section
for printing to HP lasers.
If you want to produce files for displaying and printing with Windows, use
some tools from the pbm-package like follow
g3cat $i | g3topbm - | ppmtopcx - >$i.pcx
and view it with your favourite Windows tool (maybe paintbrush)
Now making the fax-server:
fetch the file
and place it in
prepare your faxspool file as mentioned in this file
edit fax/faxspool.in and reinstall or change the final
if [ "$user" = "root" -o "$user" = "fax" -o \
"$user" = "lp" -o "$user" = "daemon" -o "$user" = "bin" ]
find the first line and change the second.
make sure you have pbmtext (from the pbm-package). This is
needed for creating the small header line on each page.
make sure your ghostscript is functional. You need fonts !
I prefer these from the OS/2 disks
prepare your faxheader
edit your /etc/printcap file:
edit your /usr/local/samba/lib/smb.conf
so you have a smb based printer named "fax"
The final step:
Now you have a printer called "fax" which can be used via
TCP/IP-printing (lpd-system) or via SAMBA (windows printing).
On every system you are able to produce postscript-files you
are ready to fax.
On Windows 3.1 95 and NT:
Install a printer wich produces postscript output,
e.g. apple laserwriter
connect the "fax" to your printer
Now write your first fax. Use your favourite wordprocessor,
write, winword, notepad or whatever you want, and start
with the headerpage.
Usually each fax has a header page. It carries your name,
your address, your phone/fax-number.
It carries also the recipient, his address and his *** fax
number ***. Now here is the trick:
Use the text:
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.
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.
Now print your fax through the fax-printer and it will be
queued for later transmission. Use faxrunq for sending the
