portmanager daemon
There is normally no need to stop and restart the daemon. To restart the daemon normally, just run the command:
# portmanager
Supported command line options are:
Force portmanager to run in the foreground: --nodaemon
Set the level of debug logging: --loglevel={debug,info,warn,error,alert}
Change which configuration file it uses: -c /etc/config/portmanager.conf
Signals
Sending a SIGHUP signal to the portmanager will cause it to re-read its configuration file
15.2.2 External Scripts and Alerts
The portmanager has the ability to execute external scripts on certain events.
When a port is opened by the portmanager:
- When the portmanager opens a port, it attempts to execute /etc/config/scripts/portXX.init (where XX is the number of
the port, e.g. 08). The script is run with STDIN and STDOUT both connected to the serial port.
- If the script cannot be executed, then portmanager will execute /etc/config/scripts/portXX.chat via the chat command
on the serial port.
When an alert occurs on a port:
- When an alert occurs on a port, the portmanager will attempt to execute /etc/config/scripts/portXX.alert (where XX is
the port number, e.g. 08)
- The script is run with STDIN containing the data which triggered the alert, and STDOUT redirected to /dev/null, NOT
to the serial port. If you wish to communicate with the port, use pmshell or pmchat from within the script.
- If the script cannot be executed, then the alert will be mailed to the address configured in the system administration
section.
When a user connects to any port:
- If a file called /etc/config/pmshell-start.sh exists it is run when a user connects to a port. It is provided 2 arguments,
the "Port number" and the "Username". Here is a simple example:
</etc/config/pmshell-start.sh >
#!/bin/sh
PORT="$1"
USER="$2"
echo "Welcome to port $PORT $USER"
< /etc/config/pmshell-start.sh>
- The return value from the script controls whether the user is accepted or not, if 0 is returned (or nothing is done on
exit as in the above script) the user is permitted, otherwise the user is denied access.
