All it does is picking options from the command line and calling \&\fIDBI::ProxyServer::main()\fR. See DBI::ProxyServer for details. .PP Available options include: .IP "\fB\-\-chroot=dir\fR" 4 .IX Item "--chroot=dir" (\s-1UNIX\s0 only) After doing a \fIbind()\fR, change root directory to the given directory by doing a \fIchroot()\fR. This is useful for security, but it restricts the environment a lot. For example, you need to load \s-1DBI\s0 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: .Sp .Vb 9 \& my $rootdir = \*(Aq/var/dbiproxy\*(Aq; \& my $unixsockdir = \*(Aq/tmp\*(Aq; \& my $unixsockfile = \*(Aqmysql.sock\*(Aq; \& foreach $dir ($rootdir, "$rootdir$unixsockdir") { \& mkdir 0755, $dir; \& } \& link("$unixsockdir/$unixsockfile", \& "$rootdir$unixsockdir/$unixsockfile"); \& require DBD::mysql; \& \& { \& \*(Aqchroot\*(Aq => $rootdir, \& ... \& } .Ve .Sp If you don't know \fIchroot()\fR, think of an \s-1FTP\s0 server where you can see a certain directory tree only after logging in. See also the \-\-group and \&\-\-user options. .IP "\fB\-\-configfile=file\fR" 4 .IX Item "--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 \*(L"\s-1CONFIGURATION\s0 \s-1FILE\s0\*(R" section in the DBI::ProxyServer documentation for details on the config file. .IP "\fB\-\-debug\fR" 4 .IX Item "--debug" Turn debugging mode on. Mainly this asserts that logging messages of level \*(L"debug\*(R" are created. .IP "\fB\-\-facility=mode\fR" 4 .IX Item "--facility=mode" (\s-1UNIX\s0 only) Facility to use for Sys::Syslog. The default is \&\fBdaemon\fR. .IP "\fB\-\-group=gid\fR" 4 .IX Item "--group=gid" After doing a \fIbind()\fR, change the real and effective \s-1GID\s0 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. .Sp \&\s-1GID\s0's can be passed as group names or numeric values. .IP "\fB\-\-localaddr=ip\fR" 4 .IX Item "--localaddr=ip" By default a daemon is listening to any \s-1IP\s0 number that a machine has. This attribute allows to restrict the server to the given \&\s-1IP\s0 number. .IP "\fB\-\-localport=port\fR" 4 .IX Item "--localport=port" This attribute sets the port on which the daemon is listening. It must be given somehow, as there's no default. .IP "\fB\-\-logfile=file\fR" 4 .IX Item "--logfile=file" Be default logging messages will be written to the syslog (Unix) or to the event log (Windows \s-1NT\s0). On other operating systems you need to specify a log file. The special value \*(L"\s-1STDERR\s0\*(R" forces logging to stderr. See Net::Daemon::Log for details. .IP "\fB\-\-mode=modename\fR" 4 .IX Item "--mode=modename" The server can run in three different modes, depending on the environment. .Sp 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 \fIRun()\fR method and then terminate. This mode is the default, you can force it with \*(L"\-\-mode=threads\*(R". .Sp If threads are not available, but you have a working \fIfork()\fR, 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 \*(L"\-\-mode=fork\*(R" option. .Sp Finally there's a single-connection mode: If the server has accepted a connection, he will enter the \fIRun()\fR method. No other connections are accepted until the \fIRun()\fR method returns (if the client disconnects). This operation mode is useful if you have neither threads nor \fIfork()\fR, for example on the Macintosh. For debugging purposes you can force this mode with \*(L"\-\-mode=single\*(R". .IP "\fB\-\-pidfile=file\fR" 4 .IX Item "--pidfile=file" (\s-1UNIX\s0 only) If this option is present, a \s-1PID\s0 file will be created at the given location. Default is to not create a pidfile. .IP "\fB\-\-user=uid\fR" 4 .IX Item "--user=uid" After doing a \fIbind()\fR, change the real and effective \s-1UID\s0 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. .Sp \&\s-1UID\s0's can be passed as group names or numeric values. .IP "\fB\-\-version\fR" 4 .IX Item "--version" Suppresses startup of the server; instead the version string will be printed and the program exits immediately. .SH "AUTHOR" .IX Header "AUTHOR" .Vb 4 \& Copyright (c) 1997 Jochen Wiedmann \& Am Eisteich 9 \& 72555 Metzingen \& Germany \& \& Email: joe@ispsoft.de \& Phone: +49 7123 14881 .Ve .PP The DBI::ProxyServer module is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
