NAME

     dhisd -- Dynamic Host Information System server.

SYNOPSIS

     dhisd [-D] [-p port] [-d database] [-s services] [-l logfile] [-P pidfile]

DESCRIPTION

     DHIS is a client-server architecture meant to update databases for systems which are assigned a dynamic IP[v4] address.

     By the means of a DHIS client a host which is assigned a dynamic IP address (either from its ISP or from DHCP) is able to communicate with a
     DHIS server in order to advertise its newly acquired IP address.

     DHIS comprises a UDP based protocol to achieve this purpose.

     A DHIS client has a unique identification number and a set of authentication keys, runs in background, and attempts to reach its server.

     The DHIS server (permanently online) listens to UDP messages from its clients and authenticates these against its knowledge of keys. When
     authentication is successful the DHIS server updates one or more databases with the newly received IP address for the given client.

     The server then keeps sending, every period of time, check requests to each of its connected clients. These need to be acknowledged. If not
     the server will consider, on an individual basis, that the client has disconnected and will again update the databases to an offline state.

     Alternativelly the server may receive an OFFLINE_REQ packet from the client, in which case the DNS record is updated at once and the online
     state droped.

OPTIONS

     -D      Increase debug level.

     -p port
	     Specify port to listen on. If not specified, the default is port 58800.

     -d database
	     Use an alternative database file instead of /etc/dhis-server/dhis.db.

     -s services
	     Use an alternative database file instead of /etc/dhis-server/services.db.

     -l logfile
	     Use an alternative log file instead of /var/log/dhisd.log.

     -P pidfile
	     Use an alternative PID file instead of /var/run/dhisd.pid.

FILES

     /etc/dhis-server/dhis.db
	     DHIS client database.  Contains the credentials of clients.

     /etc/dhis-server/services.db
	     DHIS service database.  Contains a list of services and the location of the corresponding DHIS engine plugins.

NAME

       bubbros-server - the bub-n-bros server.

SYNOPSIS

       bubbros-server [ level-file.bin ] [options]

DESCRIPTION

       bubbros-server  starts  an http server that acts as a control panel for the server. The server listens on port 8000 by default. The url for
       the control panel is http://server:port/0xN where 0xN is a random hex number (acts as minimal protection). This url  is	printed  when  the
       server  starts.	You can start and view games and kill the server from this panel. The control panel also allows you to type in the address
       of a server to connect to, the script will then open a client to that server. The http server also servers java applet  clients	for  those
       players who wish to use one.

       When  a	game  is  started the script opens a port for the game server. This port can then be connected to by a client.	Clients autodetect
       servers running on the local network with UDP ping on port 8056.

   Connection forming
       The client forms a tcp connection to the server. Or, when using the metaserver, the server forms a connection to the client. If this fails,
       the  client  and server try a simultaneous SYN connect. This sometimes works if the server and client are behind firewalls. The server then
       tries to transmit the data over udp. If it gets no response from the client it will fall back to the existing tcp connection.

OPTIONS

       -b N, --begin N, --start N
	      Start at board (level) number N.	The default is 1. See also the -s option.

       -h, --help
	      Display help.

       -i, --infinite
	      Restart the server at the end of the game. Normally the server quits after a certain period of inactivity. This is useful when  used
	      with the -m option to make a public server that is available for a long time.

       -l N, --lives N
	      Limit number of lives to N.  If this option is not specified the number of lives will be infinite.

       -m, --metaserver
	      Register server with the Metaserver (currently) at codespeak.net:8050.  This makes your server visible to everybody, and also facil-
	      itates joining through a fascistic firewall.

       --port TYPE=N Sets default listening ports. If type is LISTEN , sets the game server port to N.	The game server port is chosen randomly by
	      default.	If the type is HTTP , sets the http server port to N.  The http server port defaults to 8000.  Another port will be chosen
	      if none was specified and 8000 is already in use. The server also listens to UDP ping on port 8056.

       -s N, --step N
	      Increase board number with N when a board is completed. Defaults to 1. see also the -b option.

OUTPUT

       The server outputs helpful debug information concerning the http and game servers.
