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.
