48.Dt RBOOTD 8
49.Os
50.Sh NAME
51.Nm rbootd
52.Nd HP remote boot server
53.Sh SYNOPSIS
54.Nm
55.Op Fl ad
56.Op Fl i Ar interface
57.Op config_file
58.Sh DESCRIPTION
59The
60.Nm
61utility services boot requests from Hewlett-Packard workstations over a
62local area network.
63All boot files must reside in the boot file directory; further, if a
64client supplies path information in its boot request, it will be silently
65stripped away before processing.
66By default,
67.Nm
68only responds to requests from machines listed in its configuration file.
69.Pp
70The options are as follows:
71.Bl -tag -width indent
72.It Fl a
73Respond to boot requests from any machine.
74The configuration file is ignored if this option is specified.
75.It Fl d
76Run
77.Nm
78in debug mode.
79Packets sent and received are displayed to the terminal.
80.It Fl i Ar interface
81Service boot requests on specified interface.
82If unspecified,
83.Nm
84searches the system interface list for the lowest numbered, configured
85``up'' interface (excluding loopback).
86Ties are broken by choosing the earliest match.
87.El
88.Pp
89Specifying
90.Ar config_file
91on the command line causes
92.Nm
93to use a different configuration file from the default.
94.Pp
95The configuration file is a text file where each line describes a particular
96machine.
97A line must start with a machine's Ethernet address followed by an optional
98list of boot file names.
99An Ethernet address is specified in hexadecimal with each of its six octets
100separated by a colon.
101The boot file names come from the boot file directory.
102The ethernet address and boot file(s) must be separated by white-space
103and/or comma characters.
104A pound sign causes the remainder of a line to be ignored.
105.Pp
106Here is a sample configuration file:
107.Bl -column 08:00:09:0:66:ad SYSHPBSD,SYSHPUX
108.It #
109.It "# ethernet addr	boot file(s)	comments
110.It #
111.It "08:00:09:0:66:ad	SYSHPBSD	# snake (4.3BSD)
112.It "08:00:09:0:59:5b		# vandy (anything)
113.It "8::9:1:C6:75	SYSHPBSD,SYSHPUX	# jaguar (either)
114.El
115.Pp
116.Nm Rbootd
117logs status and error messages via
118.Xr syslog 3 .
119A startup message is always logged, and in the case of fatal errors (or
120deadly signals) a message is logged announcing the server's termination.
121In general, a non-fatal error is handled by ignoring the event that caused
122it (e.g. an invalid Ethernet address in the config file causes that line
123to be invalidated).
124.Pp
125The following signals have the specified effect when sent to the server
126process using the
127.Xr kill 1
128command:
129.Bl -tag -width SIGUSR1 -offset -compact
130.It SIGHUP
131Drop all active connections and reconfigure.
132.It SIGUSR1
133Turn on debugging, do nothing if already on.
134.It SIGUSR2
135Turn off debugging, do nothing if already off.
136.El
137.Sh "FILES"
138.Bl -tag -width /usr/libexec/rbootd -compact
139.It Pa /dev/bpf#

151.Xr kill 1 ,
152.Xr socket 2 ,
153.Xr signal 3 ,
154.Xr syslog 3
155.Sh BUGS
156If multiple servers are started on the same interface, each will receive
157and respond to the same boot packets.
