-.Os
-.Sh NAME
-.Nm rbootd
-.Nd HP remote boot server
-.Sh SYNOPSIS
-.Nm rbootd
-.Op Fl ad
-.Op Fl i Ar interface
-.Op config_file
-.Sh DESCRIPTION
-The
-.Nm rbootd
-utility services boot requests from Hewlett-Packard workstations over a
-local area network.
-All boot files must reside in the boot file directory; further, if a
-client supplies path information in its boot request, it will be silently
-stripped away before processing.
-By default,
-.Nm rbootd
-only responds to requests from machines listed in its configuration file.
-.Pp
-The options are as follows:
-.Bl -tag -width Fl
-.It Fl a
-Respond to boot requests from any machine.
-The configuration file is ignored if this option is specified.
-.It Fl d
-Run
-.Nm rbootd
-in debug mode.
-Packets sent and received are displayed to the terminal.
-.It Fl i Ar interface
-Service boot requests on specified interface.
-If unspecified,
-.Nm rbootd
-searches the system interface list for the lowest numbered, configured
-``up'' interface (excluding loopback).
-Ties are broken by choosing the earliest match.
-.El
-.Pp
-Specifying
-.Ar config_file
-on the command line causes
-.Nm rbootd
-to use a different configuration file from the default.
-.Pp
-The configuration file is a text file where each line describes a particular
-machine.
-A line must start with a machine's Ethernet address followed by an optional
-list of boot file names.
-An Ethernet address is specified in hexadecimal with each of its six octets
-separated by a colon.
-The boot file names come from the boot file directory.
-The ethernet address and boot file(s) must be separated by white-space
-and/or comma characters.
-A pound sign causes the remainder of a line to be ignored.
-.Pp
-Here is a sample configuration file:
-.Bl -column 08:00:09:0:66:ad SYSHPBSD,SYSHPUX "# vandy (anything)"
-.It #
-.It # ethernet addr boot file(s) comments
-.It #
-.It 08:00:09:0:66:ad SYSHPBSD # snake (4.3BSD)
-.It 08:00:09:0:59:5b # vandy (anything)
-.It 8::9:1:C6:75 SYSHPBSD,SYSHPUX # jaguar (either)
-.El
-.Pp
-.Nm Rbootd
-logs status and error messages via
-.Xr syslog 3 .
-A startup message is always logged, and in the case of fatal errors (or
-deadly signals) a message is logged announcing the server's termination.
-In general, a non-fatal error is handled by ignoring the event that caused
-it (e.g. an invalid Ethernet address in the config file causes that line
-to be invalidated).
-.Pp
-The following signals have the specified effect when sent to the server
-process using the
-.Xr kill 1
-command:
-.Bl -tag -width SIGUSR1 -offset -compact
-.It SIGHUP
-Drop all active connections and reconfigure.
-.It SIGUSR1
-Turn on debugging, do nothing if already on.
-.It SIGUSR2
-Turn off debugging, do nothing if already off.
-.El
-.Sh "FILES"
-.Bl -tag -width /usr/libexec/rbootd -compact
-.It /dev/bpf#
-packet-filter device
-.It /etc/rbootd.conf
-configuration file
-.It /tmp/rbootd.dbg
-debug output

-process id
-.El
-.Sh SEE ALSO
-.Xr kill 1 ,
-.Xr socket 2 ,
-.Xr signal 3 ,
-.Xr syslog 3 ,
-.Xr rmp 4
-.Sh BUGS
-If multiple servers are started on the same interface, each will receive
-and respond to the same boot packets.
