OpenMDAO factory service process.
Usage: python objserverfactory.py [--allow-public][--allow-shell][--hosts=filename][--types=filename][--users=filename][--address=address][--port=number][--prefix=name][--tunnel][--resources=filename][--log-host=hostname][--log-port=number][--log-prefix=string]
--allow-public:
Allows access by anyone from any allowed host. Use with care!
--allow-shell:
Allows access to :meth:`execute_command` and :meth:`load_model`.
Use with care!
--hosts: string
Filename for allowed hosts specification. Default ``hosts.allow``.
Ignored if '--users' is specified.
The file should contain IPv4 host addresses, IPv4 domain addresses,
or hostnames, one per line. Blank lines are ignored, and '#' marks the
start of a comment which continues to the end of the line.
For security reasons this file must be accessible only by the user
running this server.
--types: string
Filename for allowed types specification.
If not specified then allow types listed by
:meth:`factorymanager.get_available_types`.
The file should contain one type name per line.
--users: string
Filename for allowed users specification.
Ignored if '--allow-public' is specified.
Default is ``~/.ssh/authorized_keys``, other files should be of the
same format: each line has ``key-type public-key-data user@host``,
where `user` is the username on `host`. `host` will be translated to an
IPv4 address and included in the allowed hosts list.
Note that this ``user@host`` form is not necessarily enforced by
programs which generate keys.
For security reasons this file must be accessible only by the user
running this server.
--address: string
IPv4 address, hostname, or pipe name.
Default is the host's default IPv4 address.
--port: int
Server port (default of 0 implies next available port).
Note that ports below 1024 typically require special privileges.
If port is negative, then a local pipe is used for communication.
--prefix: string
Prefix for configuration and stdout/stderr files (default ``server``).
--tunnel:
Report host IP address but listen for connections from a local
SSH tunnel.
--resources: string
Filename for resource configuration. If not specified then the
default of ``~/.openmdao/resources.cfg`` will be used.
--log-host: string
Hostname to send remote log messages to.
--log-port: int
Port on `log-host` to send remote log messages to.
--log-prefix: string
Prefix to apply to remote log messages. Default is ``pid@host``.
If ``prefix.key`` exists, it is read for an authorization key string.
Otherwise public key authorization and encryption is used.
Allowed hosts *must* be specified if `port` is >= 0. Only allowed hosts
may connect to the server.
Once initialized ``prefix.cfg`` is written with address, port, and
public key information.
