- 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).
