Start the PandA server

The PandA socket server normally starts automatically at boot time or when the zpkg-daemon script is run. It is started and stopped by the script etc/panda-server installed at /opt/etc/init.d.

The server can also be started from the command line with the following options.

-h

Display help text listing all available command-line options.

-p port

TCP port for configuration commands. Default: 8888.

-d port

TCP port for data capture. Default: 8889.

-R

Allow socket reuse via the SO_REUSEADDR socket option.

-c config-dir

Directory from which the config, registers, and description files are loaded. This argument must be specified.

-f persistence-file

File from which persistence state is loaded on startup and to which it is saved during operation. If not specified, persistence state is not saved.

-t [poll][:holdoff[:backoff]]

Three parameters (in seconds) controlling writes to the persistence file.

Every poll seconds the server checks for configuration changes. If a change is found, it waits a further holdoff seconds before writing. It then waits backoff seconds before resuming polling.

Defaults: poll = 2, holdoff = 10, backoff = 60. With these defaults all parameters reach the persistence file within 72 seconds.

The colon syntax lets you set any subset: for example -t:20 sets holdoff = 20 while leaving poll and backoff unchanged.

-D

Run the server as a daemon. This is the normal production mode; omit for debugging.

-P pid-file

Write the server process ID to the given file; the file is deleted on exit.

-T

Config-file validation mode: the server exits immediately after loading configuration files without accepting connections.

-M MAC-list

Initialise up to four MAC address registers from the given file. The file may contain comment lines (starting with #) and up to four MAC address lines, each either blank or a six-octet address in XX:XX:XX:XX:XX:XX format.

-X port

Connect to an extension server running locally on the specified port. See Extension server for details.

-r rootfs-version

Specify the rootfs version string reported by the *IDN? command.
