3This is an enhanced version of the CMU BOOTP server which was derived
4from the original BOOTP server created by Bill Croft at Stanford.
5This version merges all the enhancements and bug-fixes from the
6NetBSD, Columbia, and other versions.

17BOOTPD is a useful adjunct to the nfs diskless boot EPROM code.
18
19The alternatives for initiating a boot of a kernel across a network
20are to use RARP protocol, or BOOTP protocol. BOOTP is more flexible;
21it allows additional items of information to be returned to the
22booting client; it also supports booting across gateways.

26Notes:
271) BOOTP was originally designed and implemented by Bill Croft at Stanford.
28   Much of the credit for the ideas and the code goes to him.  We've added
29   code to support the vendor specific area of the packet as specified in
30   RFC1048.  We've also improved the host lookup algorithm and added some
31   extra logging.
32
332) The server now uses syslog to do logging.  Specifically it uses the 4.3bsd
34   version.  I've #ifdef'd all of these calls.  If you are running 4.2 you
35   should compile without the -DSYSLOG switch.
36
373) You must update your /etc/services file to contain the following two lines:
38	bootps		67/udp		bootp		# BOOTP Server
39	bootpc		68/udp				# BOOTP Client
40
414) Edit the bootptab.  It has some explanitory comments, and there
42   is a manual entry describing its format (bootptab.5)
43   If you have any questions, just let us know.

48    Make sure all of the files exist first.  If anything is missing,
49    please contact either Walt Wimer or Drew Perkins by E-mail or phone.
50    Addresses and phone numbers are listed below.
51
52    Type 'make'.  The options at present are: -DSYSLOG which enables logging
53    code, -DDEBUG which enables table dumping via signals, and -DVEND_CMU
54    which enables the CMU extensions for CMU PC/IP.
55
56    Edit the bootptab.  The man page and the comments in the file should
57    explain how to go about doing so.  If you have any problems, let me know.
58
59    Type 'make install'.  This should put all of the files in the right place.
60
61    Edit your /etc/rc.local or /etc/inetd.conf file to start up bootpd upon
62    reboot.  The following is a sample /etc/inetd.conf entry:
63	# BOOTP server
64	bootps dgram udp wait root /usr/etc/bootpd bootpd -i
65
66Care and feeding:
67    If you change the interface cards on your host or add new hosts you will
68    need to update /etc/bootptab.  Just edit it as before.  Once you write
69    it back out, bootpd will notice that there is a new copy and will
70    reread it the next time it gets a request.
71
72    If your bootp clients don't get a response then several things might be
73    wrong.  Most often, the entry for that host is not in the database.
74    Check the hardware address and then check the entry and make sure
75    everything is right.  Other problems include the server machine crashing,
76    bad cables, and the like.  If your network is very congested you should
77    try making your bootp clients send additional requests before giving up.
