lib/arcx.pod  view on Meta::CPAN

Read the /default/etc/passwd on the server machine and write it locally
to /etc/passwd.

=back

=head1 USAGE

As usual a command line interface has some parameters to influence the behaviour.

The scheme looks like this:

arcx [-h <hostname>] [-p <port>] [-l <loglevel] [-L <logdestination] [-n] [-v] [-S <service>] [-F -f <history>] [-u|-U <username>] [-a|-A <authname>] [-w|-W <password>] [-s <mech>] [-t <timeout in sec>] [-r <string>] [command [command-arguments]]

=head2 Parameter

=over 4

=item -h <hostname>

The hostname, where the ARCv2 server is running. If no -h option is given, arcx will use the one chosen at compile time ($Arc::DefaultHost).

lib/arcxd.pod  view on Meta::CPAN

Let arcxd store the pid of the master process in arcxd.pid.

=back

=head1 USAGE

Some parameters can be supplied to this scripts. The most of them come from the configuration file.

By default arcxd fork itself into background. If you want to run arcx in the foreground set the -d option.

The scheme looks like this:

arcxd [-d <loglevel>] [-p <port>] [-F <config file>] [-v]

=head2 Parameter

=over 4

=item -d <loglevel>

Let the server put its log output to "stderr" and set the log level to <loglevel>. Also tells the server to do not fork into the background.
