XTSERV(6)							     XTSERV(6)

NAME
       xtserv - server for a synchronous multiplayer tetris

SYNOPSIS
       xtserv  [  -help	 ]  [  -once  ]	 [  -daemon  ] [ -v ] [ -norestart ] [
       -nospeedup ] [ -p port ]

OPTIONS
       -daemon
	      Makes xtserv detach from its controlling terminal,  fork	twice,
	      close  all its file descriptors and change the current directory
	      to '/'.  Useful to start xtserv via rsh or from scripts.

       -help  Prints out a summary of the command-line options	xtserv	recog‐
	      nizes.

       -once  With  this  option, xtserv will exit after all clients have dis‐
	      connected.

       -v     Sets verbose mode: xtserv will print information on clients con‐
	      necting,	disconnecting,	starting  games,  sending  each	 other
	      lines, losing, etc.

       -norestart
	      With this option, xtserv will not start  a  new  game  when  all
	      players  but  one have lost.  The players will have to press the
	      'play' button themselves to start.

       -nospeedup
	      With this option, xtserv will  not  automatically	 increase  the
	      game  speed  every  time	some user's number of lines is greater
	      than 10 x the current level.

       -p     Specifies a port for xtserv to use.  The default is 19503.

DESCRIPTION
       xtserv is the server for the synchronous multi-user version of  Tetris,
       xtris.

       xtserv listens for connections on a TCP port, keeps an internal list of
       connected clients, and broadcasts information among clients  to	manage
       starting	 the  game, setting the level and mode, as well as seeing each
       other's screens.

       xtserv is started automatically by xtris, with the option  '-once',  if
       xtris  does not find an xtserv running on localhost, and no server host
       has been specified.

       xtserv will automatically restart a game when the  one-but-last	player
       has lost, unless started with the option -norestart.  It will not auto‐
       matically restart a game if the user is playing alone.

       xtserv will also drop all bots when there are only  bots	 left  in  the
       game.

       The  server can handle clients exiting, being killed or losing the con‐
       nection even in the middle of a game.

       Killing an xtserv will cause all connected clients to exit.
