MODULEPROPAGATIONMONITOR.CONF(5) File Formats MODULEPROPAGATIONMONITOR.CONF(5) NAME ModulePropagationMonitor.conf - Configuration file for the SvxLink server PropagationMonitor module DESCRIPTION svxlink is a general purpose voice service system for ham radio use. This man-page describe the SvxLink server configuration for the PropagationMoni- tor module. The PropagationMonitor module is used to announce propagation alerts re- ceived from vhfdx.info or gooddx.net. The process of receiving the emails is outside of this module and have to be arranged separately. This module expect to find new emails under the spool directory. Messages from VHFDX should be put in a vhfdx subdirectory and messages from GoodDX should be put in a dxrobot subdirectory. This module must have write access to the subdirectories under the spool directory since it will move processed mes- sages to an archive directory. CONFIGURATION VARIABLES There are a couple of configuration variables that are common to all mod- ules. The documentation for these can be found in the svxlink.conf(5) man- ual page. Here is the description of all module specific configuration variables that the SvxLink PropagationMonitor module understands. ModulePropagationMonitor SPOOL_DIR Specify which directory to read incoming emails from. The default is /var/spool/svxlink/propagation_monitor. RECEIVING THE ALERT EMAILS The first step in setting up the flow of alert emails is to actually get- ting them to the computer running SvxLink and, on that computer, to the user SvxLink run as. This can be done in two ways. One way is to forward emails directly via SMTP to the computer, if you have that possibility. A more common case propably is that you want to fetch alert emails using POP from some email account. The latter can be done using the fetchmail(1) utility for example. The next step is to store incoming emails in files under the propagation monitor spool directory. This is done using the procmail(1) utility. When an incoming email is received, the mail server call procmail which look for a configuration file in the destination users home directory. For SvxLink, the home directory should be set to /etc/svxlink. In that directory a procmail configuration file, .procmailrc, is installed by default. The syn- tax is a bit cryptic but the file contains some helpful comments to help you understand it. Have a look at the procmailrc (5) and procmailex(5) man- ual pages for more details. Finally, of course, you need to register with the vhfdx.info and/or gooddx.net site and set up for what geographic area and which bands you wish to receive alert emails for. SELINUX Some Linux distributions have the SELinux security framework enabled. This is true for RedHat based distributions, like Fedora for example. SELinux will by default deny procmail to write the mail files in the propagation monitor spool directory. To fix this, run the following commands: semanage fcontext -a -t user_home_t \ "/var/spool/svxlink/propagation_monitor(/.*)?" restorecon -r /var/spool/svxlink/propagation_monitor FILES /etc/svxlink/svxlink.conf (or deprecated /etc/svxlink.conf) The system wide configuration file. ~/.svxlink/svxlink.conf Per user configuration file. /etc/svxlink/svxlink.d/ModulePropagationMonitor.conf Global modularized configuration file. Depends on the CFG_DIR con- figuration variable setting. ~/.svxlink/svxlink.d/ModulePropagationMonitor.conf Per user modularized configuration file. Depends on the CFG_DIR con- figuration variable setting. /var/spool/svxlink/propagation_monitor Spool directory for alert mails. This is the default path. What path is actually used is determined by the SPOOL_DIR configuration vari- able. /etc/svxlink/.procmailrc The configuration file for procmail. Procmail is used to write in- coming alert emails into files in the spool directory.
