-  
-!!2. Questions & Answers  
-  
-!!2.1 What is a fax printer server ?  
-  
-  
-  
- 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 sending printout to a printer.  
-  
-  
-  
-  
-!!2.2 How to set it up ?  
-  
-  
-  
-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:  
-  
-  
-  
-  
-!The efax Software  
-  
-  
-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/efax08a.tar.gz  
-or binary rpm package:  
-ftp://ftp.redhat.com/pub/redhat/redhat-4.2/i386/!RedHat/RPMS/efax-.8a-3.i386.rpm  
-  
-!The printcap entry.  
-  
-  
-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:  
-  
-  
-  
-  
-  
-  
-!The fax command  
-  
-  
- Use hard link and not symbolic link to the fax command.  
-  
-  
-Run the command:  
-  
-  
-ln /usr/bin/fax /usr/bin/faxlpr  
-  
-  
-  
-  
-  
-  
-!The /usr/bin/fax file.  
-  
-  
- Edit the /usr/bin/fax to your preferences:  
-  
-  
- choose the right Fax Class for your modem:  
-  
-  
-CLASS=2.  
-  
-  
-Set the FROM="your international phone number" field  
-  
-  
-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// -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 $cfile`  
-  
-  
-  
-  
-at lines 586,587 there shouldn't be '-' signs the lines are:  
-  
-  
-  
-  
-  
-) echo "$l" | mail -s "fax to $num succeeded" $user@$host ;;  
-*) echo "$l" | mail -s "fax to $num failed " $user@$host ;;  
-  
-  
-  
-  
-  
-  
-!The /var/spool/fax directory.  
-  
-  
- create the directory /var/spool/fax  
-  
-  
-mkdir /var/spool/fax  
-chmod 777 /var/spool/fax  
-  
-  
-  
-  
-  
-  
-!The lock file.  
-  
-  
-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  
-  
-  
-  
-  
-  
-  
-!The /dev/modem special file.  
-  
-  
-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. The file should have the rw-rw-rw- mode to enable  
-any user to use the fax software.  
-  
-  
-  
-  
-  
-ls -lL /dev/modem  
-rm /dev/modem  
-mknod /dev/modem c Mj Mi  
-chmod 666 /dev/modem  
-  
-  
-  
-  
-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  
-  
-  
-  
-  
-  
-  
-!The /var/lock directory.  
-  
-  
-change the mode at the /var/lock directory  
-  
-  
-  
-  
-  
-chmod 1777 /var/lock  
-  
-  
-  
-  
-  
-  
-  
-  
-  
-!!2.3 How do I use it, for the server ?  
-  
-  
-  
-You should use the fax printer using the -P option  
-and the -J option with the fax number.  
-  
-  
-use one of the following lpr commands:  
-  
-  
-  
-  
-  
-lpr -Pfax -J <Fax-Number> [[file-names ]  
-any command | lpr -Pfax -J <Fax-Number>  
-  
-  
-  
-  
-  
-  
-!!2.4 Where do I specify the target Fax number ?  
-  
-  
-  
-After the -J option.  
-  
-!!2.5 How do I use it from other Unixes on the net ?  
-  
-  
-  
-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#:\  
-: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).  
-  
-!!2.6 Caldera, LPRng users  
-  
-  
-  
- The LPRng printing management software is using a different method to handle the control file.  
-  
-  
-Thanks to Luca Montecchiani <m.luca@usa.net>, who found the problem and the solution.  
-Here is an update to the /usr/bin/fax file. The following line replace the two simple __cfile=...__ lines at lines 586,587  
-  
-  
-  
-  
-  
-# Modified to work also with the LPRng package  
-# Luca Montecchiani (08/11/97 m.luca@usa.net)  
-if [[ !-z "$CONTROL_FILE" ]  
-then  
-cfile=`cat tail -1 lock`  
-cfile=`cat $cfile`  
-else  
-cfile=$CONTROL_FILE  
-fi
