In client mode 55.Nm 56will broadcast a request for the specified configuration tag over available 57interfaces (or you can specify an IP), locate a server capable of supplying 58the tag, then connect to, download, and run the script associate with the 59tag. In server mode 60.Nm 61will listen on port 257 for broadcast requests (UDP) and connections (TCP). 62Note that UDP based requests are only responded to if the requested tag 63is available. You can run the server on multiple machines on the LAN 64serving different tags or, if you wish to provide a backup, serving the 65same tags, or a mix. The client will use the first matching tag it encounters. 66.Pp 67The following command line options are available when operating in client mode: 68.Bl -tag -width Fl 69.It Fl a 70.Nm 71will broadcast a request for the 'auto' tag on all available interfaces. 72No additional arguments are necessary. 73.It Fl W Ar workdir 74Specify the working directory for script downloads. The default is 75.Pa /tmp . 76.It Fl v 77Verbose mode prints additional information during program execution. 78.It host[:tag] 79Specify any number of remote IP addresses or broadcast addresses. If no 80tag is specified 81.Nm 82defaults to 'auto'. If you specify just a tag using :tag the broadcast 83address for all available interfaces will be used. The 84.Fl a 85option should not be used in that case. 86.El 87.Pp 88The following command line options are available when operating in server mode: 89.Bl -tag -width Fl 90.It Fl a 91.Nm 92will bind to and listen on all available interfaces. If this option is not 93used you must specify a particular IP address or addresses to bind to. The 94server listens on port 257 for both UDP and TCP. 95.It Fl T Ar tagdir 96Specify the directory containing the tag scripts. The default is 97.Pa /usr/local/etc/rconfig . 98Tag scripts are in the form: 99.Pa tagname.sh . 100.It Fl C Ar configfiles 101Specify server configuration files (currently unused). 102.It Fl s 103This option is required to operate 104.Nm 105as a server. 106.It Fl v 107Verbose mode prints additional information during program execution. 108.It bind_address 109Specify any number of IP addresses or hostnames corresponding to machine 110local addresses that the server will bind to and listen on. 111.El 112.Sh FILES 113.Pa /usr/share/examples/rconfig 114.Sh SEE ALSO 115.Xr dhclient 8 116.Sh AUTHORS 117This program was written by Matthew Dillon. 118
