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

SYNOPSIS
	   dbiproxy <options> --localport=<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::ProxyServer::main(). See DBI::ProxyServer
       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 useful 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 in the DBI::ProxyServer
	   documentation 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. The default is daemon.

       --group=gid
	   After doing a bind(), change the real and effective GID to the given.  This is useful,
	   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 number.

       --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 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 useful 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. Default is to not create a pidfile.

       --user=uid
	   After doing a bind(), change the real and effective UID to the given.  This is useful,
	   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.
