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