RCONFIG(8)

NAME
rconfig - Remote Configuration Client/Server

SYNOPSIS
rconfig [-a] [-v] [-W workdir] [host[:tag] ...]
rconfig -s [-a] [-C configfiles] [-T tagdir] [-v] [bind_address ...]

DESCRIPTION
The rconfig utility provides simple remote configurator functionality. In client mode rconfig will broadcast a request for the specified configuration tag over available interfaces (or you can specify an IP), locate a server capable of supplying the tag, then connect to, download, and run the script associate with the tag. In server mode rconfig will listen on port 257 for broadcast requests (UDP) and connections (TCP). Note that UDP based requests are only responded to if the requested tag is available. You can run the server on multiple machines on the LAN serving different tags or, if you wish to provide a backup, serving the same tags, or a mix. The client will use the first matching tag it encounters.

The following command line options are available when operating in client mode:

-a  rconfig will broadcast a request for the 'auto' tag on all available interfaces. No additional arguments are necessary.

-W workdir
    Specify the working directory for script downloads. The default is /tmp.

-v  Verbose mode prints additional information during program execution.

host[:tag]
    Specify any number of remote IP addresses or broadcast addresses. If no tag is specified rconfig defaults to 'auto'. If you specify just a tag using :tag the broadcast address for all available interfaces will be used. The -a option should not be used in that case.

The following command line options are available when operating in server mode:

-s  This option is required to operate rconfig as a server.

-a  rconfig will bind to and listen on all available interfaces. If this option is not used you must specify a particular IP address or addresses to bind to. The server listens on port 257 for both UDP and TCP.

-T tagdir
    Specify the directory containing the tag scripts. The default is /usr/local/etc/rconfig. Tag scripts are in the form: tagname.sh. The tag name can only consist of alphabets (lower and upper letters), digits (zero to nine), underscore (_), dot (.), minus (-) and plus (+) symbols.

-C configfiles
    Specify server configuration files (currently unused).

-v  Verbose mode prints additional information during program execution.

bind_address
    Specify any number of IP addresses or hostnames corresponding to machine local addresses that the server will bind to and listen on.
