+
+This is an enhanced version of the CMU BOOTP server which was derived
+from the original BOOTP server created by Bill Croft at Stanford.
+This version merges most of the enhancements and bug-fixes from the
+NetBSD, Columbia, and other versions.
+
+New features in version 2.4 include:
+
+ Added a simple BOOTP gateway program: bootpgw
+ Allow host name anywhere IP address is expected.
+ Automatically lookup the IP address when the name of a
+ bootptab entry is a valid hostname.
+ (Dummy entries names should start with '.')
+ Merged changes from NetBSD and Columbia versions.
+ Merged changes for Solaris-2.X and SVR4 systems.
+ Combined bootptest into the bootp release.
+ Merged tag 18 support (:ef=...:) from Jason Zions.
+ Use :ef=extension_file_name: and make the
+ extension files for all clients using bootpef.
+ Merged HP compatibility (:ra=...:) from David R Linn.
+ Allows you to override the reply address.
+ (i.e. send the reply to a broadcast address)
+ Add /etc/ethers support for NetBSD.
+ More systems support getether (Ultrix, OSF, NetBSD)
+ Added RFC 1533 tags 40,41,42
+ :yd=<NIS domain>:ys=<NIS server>:nt=<NTP server>:
+ ConvOldTab.sh to convert old (1.1) bootptab to new format.
+ Permits extended-length replies with more option data.
+
+Problems fixed in this version:
+
+ Fixed references to free host structures.
+ (used to cause core dump on Solaris)
+ Remove change that added null terminator to string options.
+ (this annoyed some clients...)
+ Add missing symbols to dump routine, fix order.
+ Works (again) with no -DSYSLOGD defined.
+ Fixed several more NULL references in readfile.
+ Added proper length checks to option insertions.
+ Fixed bootptest IP address printing.
+ Cleaned-up signed/unsigned and byteorder bugs.
+ Added SVR4/Streams support to getif and getether
+ Removed extra newlines in syslog messages.
+ Specify facility code when calling syslog(3)
+ When lookup_hwa fails, assume numeric HW address.
+
+Systems on which I have seen this code work:
+ SunOS 4.X (Solaris 1.X)
+ SunOS 5.X (Solaris 2.X)
+ System V/386 Rel. 4.0
+
+Systems on which others say this code works:
+ CDC EP/IX (1.4.3, 2.1.1)
+ DEC Ultrix (4.2, 4.3)
+ NetBSD (Current-8/94)
+ OSF/1 (DEC Alpha CPU)
+
+Please direct questions, comments, and bug reports to:

+ client requested name and bootfile specifications.
+ Behave similarly with or without CHECK_FILE_ACCESS.
+
+07/30/94 Dirk Koeppen <dirk@incom.de>
+ Add "min wait" option (mw) to cause bootpd to ignore
+ requests from clients that have not waited long enough.
+ Add code to honor client requests containing the DHCP
+ option "Maximum Message Size" and use its value to
+ determine the size of the reply message.
+
+--> bootp-2.3.8
+
+06/25/94 Christos Zoulas <christos@deshaw.com>
+ Add "-h" flag to override host name (affects default IP
+ address provided in reply messages. (Also minor bug fix)
+
+05/27/94 gwr@mc.com (Gordon W. Ross)

+
+--> bootp-2.3.7
+
+05/05/94 Walter Wong <wcw+@CMU.EDU>
+ Reduce noize at debug level one, where log messages

+
+Common problems and ways to work around them:
+
+Bootpd complains that it "can not get IP addr for HOSTNAME"
+
+ If the entry is a "dummy" (not a real host) used only for
+ reference by other entries, put '.' in front of the name.
+
+ If the entry is for a real client and the IP address for
+ the client can not be found using gethostbyname(), specify
+ the IP address for the client using numeric form.
+
+Bootpd takes a long time to finish parsing the bootptab file:
+
+ Excessive startup time is usually caused by waiting for
+ timeouts on failed DNS lookup operations. If this is the
+ problem, find the client names for which DNS lookup fails
+ and change the bootptab to specify the IP addresses for
+ those clients using numeric form.
+
+ When bootptab entries do not specify an ip address, bootpd
+ attempts to lookup the tagname as a host name to find the
+ IP address. To suppress this default action, either make
+ the entry a "dummy" or specify its IP numeric address.
+
+ If your DNS lookups work but are just slow, consider either
+ running bootpd on the same machine as the DNS server or
+ running a caching DNS server on the host running bootpd.
+
+My huge bootptab file causes startup time to be so long that clients
+give up waiting for a reply.
+
+ Truly huge bootptab files make "inetd" mode impractical.
+ Start bootpd in "standalone" mode when the server boots.
+
+ Another possibility is to run one bootpd on each network
+ segment so each one can have a smaller bootptab. Only one
+ instance of bootpd may run on one server, so you would need
+ to use a different server for each network segment.
+
+My bootp clients are given responses with a boot file name that is
+not a fully specified path.
+
+ Make sure the TFTP directory or home directory tags are set:
+ :td=/tftpboot: (or)
+ :hd=/usr/boot: (for example)

+This is an enhanced version of the CMU BOOTP server which was derived

+
+Please direct questions, comments, and bug reports to the list:

+
+You can subscribe to this mailing list by sending mail to:

+[ From the NetBSD README file: ]
+
+BOOTPD is a useful adjunct to the nfs diskless boot EPROM code.
+
+The alternatives for initiating a boot of a kernel across a network
+are to use RARP protocol, or BOOTP protocol. BOOTP is more flexible;
+it allows additional items of information to be returned to the
+booting client; it also supports booting across gateways.
+
+[ From the CMU README file: ]
+
+Notes:
+1) BOOTP was originally designed and implemented by Bill Croft at Stanford.
+ Much of the credit for the ideas and the code goes to him. We've added
+ code to support the vendor specific area of the packet as specified in
+ RFC1048. We've also improved the host lookup algorithm and added some
+ extra logging.
+
+2) The server now uses syslog to do logging. Specifically it uses the 4.3bsd
+ version. I've #ifdef'd all of these calls. If you are running 4.2 you
+ should compile without the -DSYSLOG switch.
+
+3) You must update your /etc/services file to contain the following two lines:
+ bootps 67/udp bootp # BOOTP Server
+ bootpc 68/udp # BOOTP Client
+
+4) Edit the bootptab. It has some explanitory comments, and there
+ is a manual entry describing its format (bootptab.5)
+ If you have any questions, just let us know.
+
+Construction:
+ [ See the file Installation which is more up-to-date. -gwr ]
+
+ Make sure all of the files exist first. If anything is missing,
+ please contact either Walt Wimer or Drew Perkins by E-mail or phone.
+ Addresses and phone numbers are listed below.
+
+ Type 'make'. The options at present are: -DSYSLOG which enables logging
+ code, -DDEBUG which enables table dumping via signals, and -DVEND_CMU
+ which enables the CMU extensions for CMU PC/IP.
+
+ Edit the bootptab. The man page and the comments in the file should
+ explain how to go about doing so. If you have any problems, let me know.
+
+ Type 'make install'. This should put all of the files in the right place.
+
+ Edit your /etc/rc.local or /etc/inetd.conf file to start up bootpd upon
+ reboot. The following is a sample /etc/inetd.conf entry:
+ # BOOTP server
+ bootps dgram udp wait root /usr/etc/bootpd bootpd -i
+
+Care and feeding:
+ If you change the interface cards on your host or add new hosts you will
+ need to update /etc/bootptab. Just edit it as before. Once you write
+ it back out, bootpd will notice that there is a new copy and will
+ reread it the next time it gets a request.
+
+ If your bootp clients don't get a response then several things might be
+ wrong. Most often, the entry for that host is not in the database.
+ Check the hardware address and then check the entry and make sure
+ everything is right. Other problems include the server machine crashing,
+ bad cables, and the like. If your network is very congested you should
+ try making your bootp clients send additional requests before giving up.

+.SH DESCRIPTION
+.I Bootpd
+implements an Internet Bootstrap Protocol (BOOTP) server as defined in
+RFC951, RFC1532, and RFC1533.
+.I Bootpgw
+implements a simple BOOTP gateway which can be used to forward
+requests and responses between clients on one subnet and a
+BOOTP server (i.e.
+.IR bootpd )
+on another subnet. While either
+.I bootpd
+or
+.I bootpgw
+will forward BOOTREPLY packets, only
+.I bootpgw
+will forward BOOTREQUEST packets.
+.PP
+One host on each network segment is normally configured to run either
+.I bootpd
+or
+.I bootpgw
+from
+.I inetd
+by including one of the following lines in the file
+.IR /etc/inetd.conf :
+.IP
+bootps dgram udp wait root /etc/bootpd bootpd bootptab
+.br
+bootps dgram udp wait root /etc/bootpgw bootpgw server
+.PP
+This mode of operation is referred to as "inetd mode" and causes
+.I bootpd
+(or
+.IR bootpgw )
+to be started only when a boot request arrives. If it does not
+receive another packet within fifteen minutes of the last one
+it received, it will exit to conserve system resources. The
+.B \-t
+option controls this timeout (see OPTIONS).
+.PP
+It is also possible to run
+.I bootpd
+(or
+.IR bootpgw )
+in "standalone mode" (without
+.IR inetd )
+by simply invoking it from a shell like any other regular command.
+Standalone mode is particularly useful when
+.I bootpd
+is used with a large configuration database, where the start up
+delay might otherwise prevent timely response to client requests.
+(Automatic start up in standalone mode can be done by invoking
+.I bootpd
+from within
+.IR /etc/rc.local ,
+for example.)
+Standalone mode is less useful for
+.I bootgw
+which
+has very little start up delay because
+it does not read a configuration file.
+.PP
+Either program automatically detects whether it was invoked from inetd
+or from a shell and automatically selects the appropriate mode.
+The
+.B \-s
+or
+.B \-i
+option may be used to force standalone or inetd mode respectively
+(see OPTIONS).
+.SH OPTIONS
+.TP
+.BI \-t \ timeout
+Specifies the
+.I timeout
+value (in minutes) that a
+.I bootpd
+or
+.I bootpgw
+process will wait for a BOOTP packet before exiting.
+If no packets are recieved for
+.I timeout
+seconds, then the program will exit.
+A timeout value of zero means "run forever".
+In standalone mode, this option is forced to zero.
+.TP
+.BI \-d \ debug\-level
+Sets the
+.I debug\-level
+variable that controls the amount of debugging messages generated.
+For example, -d4 or -d 4 will set the debugging level to 4.
+For compatibility with older versions of
+.IR bootpd ,
+omitting the numeric parameter (i.e. just -d) will
+simply increment the debug level by one.
+.TP
+.BI \-c \ chdir\-path
+Sets the current directory used by
+.I bootpd
+while checking the existence and size of client boot files. This is
+useful when client boot files are specified as relative pathnames, and
+.I bootpd
+needs to use the same current directory as the TFTP server
+(typically /tftpboot). This option is not recoginzed by
+.IR bootpgw .
+.TP
+.B \-i
+Force inetd mode. This option is obsolete, but remains for
+compatibility with older versions of
+.IR bootpd .
+.TP
+.B \-s
+Force standalone mode. This option is obsolete, but remains for
+compatibility with older versions of
+.IR bootpd .
+.TP
+.I bootptab
+Specifies the name of the configuration file from which
+.I bootpd
+loads its database of known clients and client options
+.RI ( bootpd
+only).
+.TP
+.I dumpfile
+Specifies the name of the file that
+.I bootpd
+will dump its internal database into when it receives a
+SIGUSR1 signal
+.RI ( bootpd
+only). This option is only recognized if
+.I bootpd
+was compiled with the -DDEBUG flag.
+.TP
+.I server
+Specifies the name of a BOOTP server to which
+.I bootpgw
+will forward all BOOTREQUEST packets it receives
+.RI ( bootpgw
+only).
+.SH OPERATION
+.PP
+Both
+.I bootpd
+and
+.I bootpgw
+operate similarly in that both listen for any packets sent to the
+.I bootps
+port, and both simply forward any BOOTREPLY packets.
+They differ in their handling of BOOTREQUEST packets.
+.PP
+When
+.I bootpgw
+is started, it determines the address of a BOOTP server
+whose name is provided as a command line parameter. When
+.I bootpgw
+receives a BOOTREQUEST packet, it sets the "gateway address"
+and "hop count" fields in the packet and forwards the packet
+to the BOOTP server at the address determined earlier.
+Requests are forwarded only if they indicate that
+the client has been waiting for at least three seconds.
+.PP
+When
+.I bootpd
+is started it reads a configuration file, (normally
+.IR /etc/bootptab )
+that initializes the internal database of known clients and client
+options. This internal database is reloaded
+from the configuration file when
+.I bootpd
+receives a hangup signal (SIGHUP) or when it discovers that the
+configuration file has changed.
+.PP
+When
+.I bootpd
+receives a BOOTREQUEST packet, it
+.\" checks the modification time of the
+.\" configuration file and reloads the database if necessary. Then it
+looks for a database entry matching the client request.
+If the client is known,
+.I bootpd
+composes a BOOTREPLY packet using the database entry found above,
+and sends the reply to the client (possibly using a gateway).
+If the client is unknown, the request is discarded
+(with a notice if debug > 0).
+.PP
+If
+.I bootpd
+is compiled with the -DDEBUG option, receipt of a SIGUSR1 signal causes
+it to dump its internal database to the file
+.I /etc/bootpd.dump
+or the dumpfile specified as a command line parameter.
+.PP
+During initialization, both programs
+determine the UDP port numbers to be used by calling
+.I getservbyname
+(which nomally uses
+.IR /etc/services).
+Two service names (and port numbers) are used:
+.IP
+bootps \- BOOTP Server listening port
+.br
+bootpc \- BOOTP Client destination port
+.LP
+If the port numbers cannot
+be determined using
+.I getservbyname
+then the values default to boopts=67 and bootpc=68.

+.SH NAME
+bootptab \- Internet Bootstrap Protocol server database
+.SH DESCRIPTION
+The
+.I bootptab
+file is the configuration database file for
+.IR bootpd ,
+the Internet Bootstrap Protocol server.
+It's format is similar to that of
+.IR termcap (5)
+in which two-character case-sensitive tag symbols are used to
+represent host parameters. These parameter declarations are separated by
+colons (:), with a general format of:
+.PP
+.I " hostname:tg=value. . . :tg=value. . . :tg=value. . . ."
+.PP
+where
+.I hostname
+is the actual name of a bootp client (or a "dummy entry"), and
+.I tg
+is a two-character tag symbol. Dummy entries have an invalid hostname
+(one with a "." as the first character) and are used to provide
+default values used by other entries via the
+.B tc=.dummy-entry
+mechanism. Most tags must be followed by an equals-sign
+and a value as above. Some may also appear in a boolean form with no
+value (i.e.
+.RI : tg :).
+The currently recognized tags are:
+.PP
+.br
+ bf Bootfile
+.br
+ bs Bootfile size in 512-octet blocks
+.br
+ cs Cookie server address list
+.br
+ df Merit dump file
+.br
+ dn Domain name
+.br
+ ds Domain name server address list
+.br
+ ef Extension file
+.br
+ gw Gateway address list
+.br
+ ha Host hardware address
+.br
+ hd Bootfile home directory
+.br
+ hn Send client's hostname to client
+.br
+ ht Host hardware type (see Assigned Numbers RFC)
+.br
+ im Impress server address list
+.br
+ ip Host IP address
+.br
+ lg Log server address list
+.br
+ lp LPR server address list
+.br
+ ns IEN-116 name server address list
+.br
+ nt NTP (time) Server (RFC 1129)
+.br
+ ra Reply address override
+.br
+ rl Resource location protocol server address list
+.br
+ rp Root path to mount as root
+.br
+ sa TFTP server address client should use
+.br
+ sm Host subnet mask
+.br
+ sw Swap server address
+.br
+ tc Table continuation (points to similar "template" host entry)
+.br
+ td TFTP root directory used by "secure" TFTP servers
+.br
+ to Time offset in seconds from UTC
+.br
+ ts Time server address list
+.br
+ vm Vendor magic cookie selector
+.br
+ yd YP (NIS) domain name
+.br
+ ys YP (NIS) server address
+
+.PP
+There is also a generic tag,
+.RI T n ,
+where
+.I n
+is an RFC1084 vendor field tag number. Thus it is possible to immediately
+take advantage of future extensions to RFC1084 without being forced to modify
+.I bootpd
+first. Generic data may be represented as either a stream of hexadecimal
+numbers or as a quoted string of ASCII characters. The length of the generic
+data is automatically determined and inserted into the proper field(s) of the
+RFC1084-style bootp reply.
+.PP
+The following tags take a whitespace-separated list of IP addresses:
+.BR cs ,
+.BR ds ,
+.BR gw ,
+.BR im ,
+.BR lg ,
+.BR lp ,
+.BR ns ,
+.BR nt ,
+.BR ra ,
+.BR rl ,
+and
+.BR ts .
+The
+.BR ip ,
+.BR sa ,
+.BR sw ,
+.BR sm ,
+and
+.B ys
+tags each take a single IP address.
+All IP addresses are specified in standard Internet "dot" notation
+and may use decimal, octal, or hexadecimal numbers
+(octal numbers begin with 0, hexadecimal numbers begin with '0x' or '0X').
+Any IP addresses may alternatively be specified as a hostname, causing
+.I bootpd
+to lookup the IP address for that host name using gethostbyname(3).
+If the
+.B ip
+tag is not specified,
+.I bootpd
+will determine the IP address using the entry name as the host name.
+(Dummy entries use an invalid host name to avoid automatic IP lookup.)
+.PP
+The
+.B ht
+tag specifies the hardware type code as either an unsigned decimal, octal, or
+hexadecimal integer or one of the following symbolic names:
+.B ethernet
+or
+.B ether
+for 10Mb Ethernet,
+.B ethernet3
+or
+.B ether3
+for 3Mb experimental Ethernet,
+.BR ieee802 ,
+.BR tr ,
+or
+.B token-ring
+for IEEE 802 networks,
+.B pronet
+for Proteon ProNET Token Ring, or
+.BR chaos ,
+.BR arcnet ,
+or
+.B ax.25
+for Chaos, ARCNET, and AX.25 Amateur Radio networks, respectively.
+The
+.B ha
+tag takes a hardware address which may be specified as a host name
+or in numeric form. Note that the numeric form
+.I must
+be specified in hexadecimal; optional periods and/or a leading '0x' may be
+included for readability. The
+.B ha
+tag must be preceded by the
+.B ht
+tag (either explicitly or implicitly; see
+.B tc
+below).
+If the hardware address is not specified and the type is specified
+as either "ethernet" or "ieee802", then
+.I bootpd
+will try to determine the hardware address using ether_hton(3).
+.PP
+The hostname, home directory, and bootfile are ASCII strings which may be
+optionally surrounded by double quotes ("). The client's request and the
+values of the
+.B hd
+and
+.B bf
+symbols determine how the server fills in the bootfile field of the bootp
+reply packet.
+.PP
+If the client provides a file name it is left as is.
+Otherwise, if the
+.B bf
+option is specified its value is copied into the reply packet.
+If the
+.B hd
+option is specified as well, its value is prepended to the
+boot file copied into the reply packet.
+The existence of the boot file is checked only if the
+.BR bs =auto
+option is used (to determine the boot file size).
+A reply may be sent whether or not the boot file exists.
+.PP
+Some newer versions of
+.I tftpd
+provide a security feature to change their root directory using
+the
+.IR chroot (2)
+system call.
+The
+.B td
+tag may be used to inform
+.I bootpd
+of this special root directory used by
+.IR tftpd .
+(One may alternatively use the
+.I bootpd
+"-c chdir" option.)
+The
+.B hd
+tag is actually relative to the root directory specified by the
+.B td
+tag.
+For example, if the real absolute path to your BOOTP client bootfile is
+/tftpboot/bootfiles/bootimage, and
+.IR tftpd
+uses /tftpboot as its "secure" directory, then specify the following in
+.IR bootptab :
+.PP
+.br
+ :td=/tftpboot:hd=/bootfiles:bf=bootimage:
+.PP
+If your bootfiles are located directly in /tftpboot, use:
+.PP
+.br
+ :td=/tftpboot:hd=/:bf=bootimage:
+.PP
+The
+.B sa
+tag may be used to specify the IP address of the particular TFTP server
+you wish the client to use. In the absence of this tag,
+.I bootpd
+will tell the client to perform TFTP to the same machine
+.I bootpd
+is running on.
+.PP
+The time offset
+.B to
+may be either a signed decimal integer specifying the client's
+time zone offset in seconds from UTC, or the keyword
+.B auto
+which uses the server's time zone offset. Specifying the
+.B to
+symbol as a boolean has the same effect as specifying
+.B auto
+as its value.
+.PP
+The bootfile size
+.B bs
+may be either a decimal, octal, or hexadecimal integer specifying the size of
+the bootfile in 512-octet blocks, or the keyword
+.B auto
+which causes the server to automatically calculate the bootfile size at each
+request. As with the time offset, specifying the
+.B bs
+symbol as a boolean has the same effect as specifying
+.B auto
+as its value.
+.PP
+The vendor magic cookie selector (the
+.B vm
+tag) may take one of the following keywords:
+.B auto
+(indicating that vendor information is determined by the client's request),
+.B rfc1048
+or
+.B rfc1084
+(which always forces an RFC1084-style reply), or
+.B cmu
+(which always forces a CMU-style reply).
+.PP
+The
+.B hn
+tag is strictly a boolean tag; it does not take the usual equals-sign and
+value. It's presence indicates that the hostname should be sent to RFC1084
+clients.
+.I Bootpd
+attempts to send the entire hostname as it is specified in the configuration
+file; if this will not fit into the reply packet, the name is shortened to
+just the host field (up to the first period, if present) and then tried.
+In no case is an arbitrarily-truncated hostname sent (if nothing reasonable
+will fit, nothing is sent).
+.PP
+Often, many host entries share common values for certain tags (such as name
+servers, etc.). Rather than repeatedly specifying these tags, a full
+specification can be listed for one host entry and shared by others via the
+.B tc
+(table continuation) mechanism.
+Often, the template entry is a dummy host which doesn't actually exist and
+never sends bootp requests. This feature is similar to the
+.B tc
+feature of
+.IR termcap (5)
+for similar terminals. Note that
+.I bootpd
+allows the
+.B tc
+tag symbol to appear anywhere in the host entry, unlike
+.I termcap
+which requires it to be the last tag. Information explicitly specified for a
+host always overrides information implied by a
+.B tc
+tag symbol, regardless of its location within the entry. The
+value of the
+.B tc
+tag may be the hostname or IP address of any host entry
+previously listed in the configuration file.
+.PP
+Sometimes it is necessary to delete a specific tag after it has been inferred
+via
+.BR tc .
+This can be done using the construction
+.IB tag @
+which removes the effect of
+.I tag
+as in
+.IR termcap (5).
+For example, to completely undo an IEN-116 name server specification, use
+":ns@:" at an appropriate place in the configuration entry. After removal
+with
+.BR @ ,
+a tag is eligible to be set again through the
+.B tc
+mechanism.
+.PP
+Blank lines and lines beginning with "#" are ignored in the configuration
+file. Host entries are separated from one another by newlines; a single host
+entry may be extended over multiple lines if the lines end with a backslash
+(\\). It is also acceptable for lines to be longer than 80 characters. Tags
+may appear in any order, with the following exceptions: the hostname must be
+the very first field in an entry, and the hardware type must precede the
+hardware address.
+.PP

+.I /etc/bootptab
+file follows:

+ *
+ * Provides multiple, dynamically-allocated, variable-sized hash tables on

+ *
+ * This package attempts to follow some of the coding conventions suggested
+ * by Bob Sidebotham and the AFS Clean Code Committee.
+ */
+
+
+/*
+ * The user must supply the following:
+ *
+ * 1. A comparison function which is declared as:
+ *
+ * int compare(data1, data2)
+ * hash_datum *data1, *data2;
+ *
+ * This function must compare the desired fields of data1 and
+ * data2 and return TRUE (1) if the data should be considered
+ * equivalent (i.e. have the same key value) or FALSE (0)
+ * otherwise. This function is called through a pointer passed to
+ * the various hashtable functions (thus pointers to different
+ * functions may be passed to effect different tests on different
+ * hash tables).
+ *
+ * Internally, all the functions of this package always call the
+ * compare function with the "key" parameter as the first parameter,
+ * and a full data element as the second parameter. Thus, the key
+ * and element arguments to functions such as hash_Lookup() may
+ * actually be of different types and the programmer may provide a
+ * compare function which compares the two different object types
+ * as desired.
+ *
+ * Example:
+ *
+ * int compare(key, element)
+ * char *key;
+ * struct some_complex_structure *element;
+ * {
+ * return !strcmp(key, element->name);
+ * }
+ *
+ * key = "John C. Doe"
+ * element = &some_complex_structure
+ * hash_Lookup(table, hashcode, compare, key);
+ *
+ * 2. A hash function yielding an unsigned integer value to be used
+ * as the hashcode (index into the hashtable). Thus, the user
+ * may hash on whatever data is desired and may use several
+ * different hash functions for various different hash tables.
+ * The actual hash table index will be the passed hashcode modulo
+ * the hash table size.
+ *
+ * A generalized hash function, hash_HashFunction(), is included
+ * with this package to make things a little easier. It is not
+ * guarenteed to use the best hash algorithm in existence. . . .

+.TH BOOTPEF 8 "4 Dec 1993" "MAINTENANCE COMMANDS"
+.SH NAME
+bootpef \- BOOTP Extension File compiler
+.SH SYNOPSIS
+.LP
+.B bootpef
+.RI [ "-c chdir" ]
+.RI [ "-d debug-level" ]
+.RI [ "-f config-file" ]
+.RI [ client-name " [...]]"
+.SH DESCRIPTION
+.B bootpef
+builds the
+.I Extension Path
+files described by RFC 1497 (tag 18).
+If any
+.I client-name
+arguments are specified, then
+.I bootpef
+compiles the extension files for only those clients.
+.SH OPTIONS
+.TP
+.BI \-c \ chdir\-path
+Sets the current directory used by
+.I bootpef
+while creating extension files. This is useful when the
+extension file names are specified as relative pathnames, and
+.I bootpef
+needs to use the same current directory as the TFTP server
+(typically /tftpboot).
+.TP
+.BI \-d \ debug\-level
+Sets the
+.I debug\-level
+variable that controls the amount of debugging messages generated.
+For example, -d4 or -d 4 will set the debugging level to 4.
+.TP
+.BI \-f \ config\-file
+Set the name of the config file that specifies the option
+data to be sent to each client.

+.TH BOOTPTEST 8 "10 June 1993" "MAINTENANCE COMMANDS"
+.SH NAME
+bootptest \- send BOOTP queries and print responses
+.SH SYNOPSIS
+.LP
+.B bootptest
+[
+.B \-f
+.I bootfile
+]
+[
+.B \-h
+]
+[
+.B \-m
+.I magic_number
+]
+.I server\-name
+.RI [ template-file ]
+.SH DESCRIPTION
+.B bootptest
+sends BOOTP requests to the host specified as
+.I server\-name
+at one\-second intervals until either a response is received,
+or until ten requests have gone unanswered.
+After a response is received,
+.B bootptest
+will wait one more second listening for additional responses.
+.SH OPTIONS
+.TP
+.B \-f
+.I bootfile
+Fill in the boot file field of the request with
+.IR bootfile .
+.TP
+.B \-h
+Use the hardware (Ethernet) address to identify the client.
+By default, the IP address is copied into the request
+indicating that this client already knows its IP address.
+.TP
+.B \-m
+.I magic_number
+Initialize the first word of the vendor options field with
+.IR magic_number .
+.LP
+A
+.I template-file
+may be specified, in which case
+.B bootptest
+uses the (binary) contents of this file to initialize the
+.I options
+area of the request packet.
+.SH CREDITS
+.LP
+The bootptest program is a combination of original and derived works.
+The main program module (bootptest.c) is original work by
+Gordon W. Ross <gwr@mc.com>.
+The packet printing module (print-bootp.c) is a slightly modified
+version of a file from the BSD tcpdump program.
+.LP
+This program includes software developed by the University of
+California, Lawrence Berkeley Laboratory and its contributors.
