arcxd - standalone ARCv2 server
This file is the scripts, which can be used, to start the ARCv2 server from the command line.
This are some examples how to run the ARCv2 server.
Start the ARCv2 server. The server will listen on the DefaultPort and all local addresses. It will read the configuration file, located in the ConfigPath. After successful listening, it will fork into the background.
- arcxd -p 1234
Same as arcxd but listens on port 1234.
- arcxd -d 5
Stay in foreground and log messages to stderr.
- arcxd -P arcxd.pid
Let arcxd store the pid of the master process in arcxd.pid.
Some parameters can be supplied to this scripts. The most of them come from the configuration file.
By default arcxd fork itself into background. If you want to run arcx in the foreground set the -d option.
The scheme looks like this:
arcxd [-d <loglevel>] [-p <port>] [-F <config file>] [-v]
- -d <loglevel>
Let the server put its log output to "stderr" and set the log level to <loglevel>. Also tells the server to do not fork into the background.
- -p <port>
On which port the server shall listen on. (override the one from the configuration file and the default port). Change this for testing purposes.
- -P <pid_file>
Where should the Net::Server store the PID of the master process.
- -F <config file>
Specify the configuration file, to fill ARCv2 appropriately. Default is arcxd.conf in the default path $Arc::Default Path.
The verbose option. If this option is set, arcxd is verbose in its context. This option does not influence the ARCv2 object. Use -d for it.

The configuration file is based on .ini format, known from Windows (sorry). In perl we can parse it, using Config::IniFiles. The configuration file is divided into several sections. Each section can have a several number of key/value pairs.
The name of the service the SASL authentication mechanism shall use.
Timeout in seconds to wait for data in control and command connection.
Here you can specify the address the server shall wait for connections. 0 lets the server listen on all interface on the host.
On which port the server shall listen on, can be overridden by the mentioned -p option.
These variables define the preforking behaviour. See Net::Server::PreFork for more detailed descriptions.
A list of the possible SASL mechanisms, the server can supply to the clients. Can be filled by using the multi-line-string method known from perl.
- Command Name = Command Class
The section [commands] defines the assignments of command names to their command class. Each line is a command in ARCv2. A class can be assigned to more than one name.
This option specifies the login level of ARCv2. Default is 5, whereas 7 is the highest (DEBUG) and 1 is the lowest.
This option defines the log output destination. Possible values are "stderr" and "syslog".
