to both ports 1 and 8.
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 can execute external scripts on certain events.
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:
-
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 want 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>
