For the client, please refer to man distcc-elb and man distcc-elb.conf for configuration options.
For the server, see man distcc-elbd.conf for configuration options. There are several sample configuration files you can use.
Starting and stopping the service works with either SysV init scripts or systemd, depending on the particular Linux release. To start/stop/restart/status the service on a SysV init based host, issue a service distcc-elbd start|stop|restart|status. To do the same on a host that runs systemd, use systemctl start|stop|restart|status distcc-elbd.
