NAME

       dbiproxy - A proxy server for the DBD::Proxy driver

SYNOPSIS

	   dbiproxy <options> --port <port>

DESCRIPTION

       This tool is just a front end for the DBI::ProxyServer package. All it does is picking options from the command line and calling DBI::Prox-
       yServer::main(). See DBI::ProxyServer(3) for details.

       Available options include:

       --chroot=dir
	   (UNIX only)	After doing a bind(), change root directory to the given directory by doing a chroot(). This is usefull for security, but
	   it restricts the environment a lot. For example, you need to load DBI drivers in the config file or you have to create hard links to
	   Unix sockets, if your drivers are using them. For example, with MySQL, a config file might contain the following lines:

	       my $rootdir = '/var/dbiproxy';
	       my $unixsockdir = '/tmp';
	       my $unixsockfile = 'mysql.sock';
	       foreach $dir ($rootdir, "$rootdir$unixsockdir") {
		   mkdir 0755, $dir;
	       }
	       link("$unixsockdir/$unixsockfile",
		    "$rootdir$unixsockdir/$unixsockfile");
	       require DBD::mysql;

	       {
		   'chroot' => $rootdir,
		   ...
	       }

	   If you don't know chroot(), think of an FTP server where you can see a certain directory tree only after logging in. See also the
	   --group and --user options.

       --configfile=file
	   Config files are assumed to return a single hash ref that overrides the arguments of the new method. However, command line arguments in
	   turn take precedence over the config file. See the "CONFIGURATION FILE" section below for details on the config file.

       --debug
	   Turn debugging mode on. Mainly this asserts that logging messages of level "debug" are created.

       --facility=mode
	   (UNIX only) Facility to use for "Sys::Syslog (3)". The default is daemon.

       --group=gid
	   After doing a bind(), change the real and effective GID to the given.  This is usefull, if you want your server to bind to a privileged
	   port (<1024), but don't want the server to execute as root. See also the --user option.

	   GID's can be passed as group names or numeric values.

       --localaddr=ip
	   By default a daemon is listening to any IP number that a machine has. This attribute allows to restrict the server to the given IP num-
	   ber.

       --localport=port
	   This attribute sets the port on which the daemon is listening. It must be given somehow, as there's no default.

       --logfile=file
	   Be default logging messages will be written to the syslog (Unix) or to the event log (Windows NT). On other operating systems you need
	   to specify a log file. The special value "STDERR" forces logging to stderr. See Net::Daemon::Log(3) for details.

       --mode=modename
	   The server can run in three different modes, depending on the environment.

	   If you are running Perl 5.005 and did compile it for threads, then the server will create a new thread for each connection. The thread
	   will execute the server's Run() method and then terminate. This mode is the default, you can force it with "--mode=threads".

	   If threads are not available, but you have a working fork(), then the server will behave similar by creating a new process for each
	   connection.	This mode will be used automatically in the absence of threads or if you use the "--mode=fork" option.

	   Finally there's a single-connection mode: If the server has accepted a connection, he will enter the Run() method. No other connections
	   are accepted until the Run() method returns (if the client disconnects).  This operation mode is usefull if you have neither threads
	   nor fork(), for example on the Macintosh. For debugging purposes you can force this mode with "--mode=single".

       --pidfile=file
	   (UNIX only) If this option is present, a PID file will be created at the given location.

       --user=uid
	   After doing a bind(), change the real and effective UID to the given.  This is usefull, if you want your server to bind to a privileged
	   port (<1024), but don't want the server to execute as root. See also the --group and the --chroot options.

	   UID's can be passed as group names or numeric values.

       --version
	   Supresses startup of the server; instead the version string will be printed and the program exits immediately.
