RBOOTD(8) BSD System Manager's Manual RBOOTD(8)
rbootd - HP remote boot server
rbootd [-ad] [-i interface] [config_file]
The rbootd utility services boot requests from Hewlett-Packard worksta- tions 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 de- fault, rbootd only responds to requests from machines listed in its con- figuration file. The options are as follows: -a Respond to boot requests from any machine. The configuration file is ignored if this option is specified. -d Run rbootd in debug mode. Packets sent and received are displayed to the terminal. -i interface Service boot requests on specified interface. If unspecified, rbootd searches the system interface list for the lowest num- bered, configured ``up'' interface (excluding loopback). Ties are broken by choosing the earliest match. Specifying config_file on the command line causes rbootd to use a dif- ferent configuration file from the default. The configuration file is a text file where each line describes a partic- ular machine. A line must start with a machine's Ethernet address fol- lowed 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 Ether- net address and boot file(s) must be separated by whitespace and/or comma characters. A pound sign causes the remainder of a line to be ignored. Here is a sample configuration file: # # ethernet addr boot file(s) comments # 08:00:09:0:66:ad SYSHPBSD # snake (4.3BSD) 08:00:09:0:59:5b # vandy (anything) 8::9:1:C6:75 SYSHPBSD,SYSHPUX # jaguar (either) rbootd logs status and error messages via syslog(3). A startup message is always logged, and in the case of fatal errors (or deadly signals) a mes- sage 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 in- valid Ethernet address in the config file causes that line to be invali- dated). The following signals have the specified effect when sent to the server process using the kill(1) command: SIGHUP Drop all active connections and reconfigure. SIGUSR1 Turn on debugging, do nothing if already on. SIGUSR2 Turn off debugging, do nothing if already off.
/dev/bpf# packet-filter device /etc/rbootd.conf configuration file /tmp/rbootd.dbg debug output /usr/mdec/rbootd directory containing boot files /var/run/rbootd.pid process ID
kill(1), socket(2), signal(3), syslog(3)
If multiple servers are started on the same interface, each will receive and respond to the same boot packets. MirOS BSD #10-current December 11, 1993 1
