RBOOTD(8) BSD System Manager's Manual RBOOTD(8) NNAAMMEE rrbboooottdd - HP remote boot server SSYYNNOOPPSSIISS rrbboooottdd [--aadd] [--ii _i_n_t_e_r_f_a_c_e] [config_file] DDEESSCCRRIIPPTTIIOONN The rrbboooottdd 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 default, rrbboooottdd only responds to requests from machines listed in its configuration file. The options are as follows: --aa Respond to boot requests from any machine. The configuration file is ignored if this option is specified. --dd Run rrbboooottdd in debug mode. Packets sent and received are dis- played to the terminal. --ii _i_n_t_e_r_f_a_c_e Service boot requests on specified interface. If unspeci- fied, rrbboooottdd searches the system interface list for the low- est numbered, configured ``up'' interface (excluding loop- back). Ties are broken by choosing the earliest match. Specifying _c_o_n_f_i_g___f_i_l_e on the command line causes rrbboooottdd to use a differ- ent 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 eth- ernet 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 ig- nored. 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) RRbboooottdd 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 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 inval- idated). 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.
