Linux simple fax printer server mini-HOWTO (faxsrv-mini-HOWTO)
Author: Erez Strauss <erez@newplaces.com>
Version 0.002, last update: Sep 24, 1997
No warnties, comments are always welcome.
This file describes one of the simples way to set fax server on
your Linux system.
I was only interested in sending faxes, as I already have fax machine ;-)
There are more complete fax systems and more complex, but ...
Questions:
Q1. What is a fax printer server ?
Q2. How To set it up ?
Q3. How do I use it, from the server ?
Q4. Where do I specify the target Fax number ?
Q5. How do I use it from other Unixes on the net ?
Q1. What is a fax printer server ?
A1. A fax printer server is a setup of few programs:
efax, and the print server, in such a way that sending a fax from
the computer is as simple as printout.
Q2. How To set it up ?
A2. Setting efax as fax print server includes few problems
As I worked it out few times, I decided to collect this wisdom
in this small mini-HOWTO, comments are welcome at <erez@newplaces.com>.
I describe them here and the solutions, and all the
instruction in short steps:
2.0 make sure you have the efax package.
on RPM based system use the command 'rpm -qv efax'.
You can get the efax sources in tar.gz format from sunsite:
ftp://sunsite.unc.edu/pub/Linux/apps/serialcomm/fax/efax08.tar.gz
or binary rpm package:
ftp://ftp.redhat.com/pub/redhat/redhat-4.2/i386/RedHat/RPMS/efax-0.8a-3.i386.rpm
2.1. The efax documentation is missing the : at the end of
the printcap entry.
Solution:
Add the following /etc/printcap entry:
fax:\
:lp=/dev/null:\
:sd=/var/spool/fax:\
:if=/usr/bin/faxlpr:
2.2. Use hard link and not symbolic link to the fax command
ln /usr/bin/fax /usr/bin/faxlpr
2.3. edit the /usr/bin/fax to your preferences:
choose the right Fax Class for your modem:
CLASS=2.0
Set the FROM="your international phone number"
NAME="Your Name"
Add the line for conversion of international phone number to local
for example in Israel you would use:
TELCVT='sed -e s/+972/0/ -e s/+/00/' # Israel
There is a problem in the file in line 586, change the
cfile=... with the following two lines:
cfile=`/usr/bin/tail -1 lock`
cfile=`cat $cfile`
at lines 586,587 there shouldn't be '-' signs the lines are:
0) echo "$l" | mail -s "fax to $num succeeded" $user@$host ;;
*) echo "$l" | mail -s "fax to $num failed " $user@$host ;;
2.4. create the directory /var/spool/fax
mkdir /var/spool/fax
chmod 777 /var/spool/fax
2.5. The lock file (/var/spool/fax/lock) is being created with
incorrect permissions, use the following command to set it correctly:
touch /var/spool/fax/lock ; chmod 644 /var/spool/fax/lock
2.6. the efax program is expecting real device file at the /dev/modem
and will not work with symbolic link, so create a device file
with the same major and minor number as the /dev/cua? the is
connected to the modem
ls -lL /dev/modem
rm /dev/modem
mknod /dev/modem c Mj Mi
Mj is 5, and Mi is 64 for the cua0, 65 for cua1 and so on.
For example (for cua1):
mknod /dev/modem c 5 65
2.7. change the mode at the /var/lock directory
chmod 1777 /var/lock
Q3. How do I use it, for the server ?
A3. You should use the fax printer using the -P option
and the -J option with the fax number.
use the following lpr commands:
lpr -Pfax -J <Fax-Number> [file-names]
or
any command | lpr -Pfax -J <Fax-Number>
Q4. Where do I specify the target Fax number ?
A4. After the -J option.
Q5. How do I use it from other Unixes on the net ?
A5. Add the following entry into the /etc/printcap file and the client
Linux systems, create the spool directory, and so on ...
fax:\
:sd=/var/spool/fax:\
:mx#0:\
:sh:\
:rm=host.domain:\
:rp=fax:
add the name of the client hosts into the /etc/hosts.lpd on the
fax server machine.
use it as before.
Note:
The header string that efax adds to the fax pages is not effected
by the user name that sends the fax. (can be updated).
