-# $FreeBSD$
-
-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:
- NetBSD-1.0 (BSD-4.4 derivative)
- 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)
- Linux 1.1.81
- OSF/1 (DEC Alpha CPU)
-

-# $FreeBSD$
-
-Common problems and ways to work around them:
-
-Bootpd complains: "bind: Address already in use" and fails to start.
- You are already running something that has bound the
- BOOTP listening port number. Check /etc/inetd.conf or
- the equivalent for a bootp line (or in startup files).
-
-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)
-
-My PC clients running Sun's PC-NFS Pro v1.1 fail to receive
-acceptable responses from the bootp server.
-
- These clients send a request with the DHCP "message length"
- option and the (new) BOOTP "broadcast flag" both set.
- The bootp server (on SunOS) will send a fragmented reply
- unless you override the length with :ms=1024: (or less).
- The "broadcast flag" is not yet supported, but there is
- a simple work-around, just add :ra=255.255.255.255:
- for any clients that need their reply broadcasted.
- You may need to use a differnet broadcast address.
- (Thanks to Ivan Auger <ivan.auger@wadsworth.org>)

-# $FreeBSD$
-
-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 all the enhancements and bug-fixes from the
-NetBSD, Columbia, and other versions.
-
-Please direct questions, comments, and bug reports to the list:
- <bootp@andrew.cmu.edu>
-
-You can subscribe to this mailing list by sending mail to:
- bootp-request@andrew.cmu.edu
-(The body of the message should contain: "Add <your-address>")
-
-[ 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.

-Memory allocation locality:
-
-Currently mallocs memory in a very haphazard manner. As such, most of
-the program ends up core-resident all the time just to follow all the
-stupid pointers around. . . .
-
-----------------------------------------------------------------------
-Input parser:
-
-The reader implemented in readfile.c could use improvement. Some sort
-of "data-driven" parser should be used so the big switch statements
-would have only one case for each data type instead of one case for
-every recognized option symbol. Then adding a new tag would involve
-only adding a new element to the data table describing known symbols.
-Hopefully, this would shrink the code a bit too. -gwr
-
-----------------------------------------------------------------------
-SLIP Initialization via BOOTP:
-
-In the function handle_request(), both in bootpd and bootpgw,
-we might want to add code like the following just before testing
-the client IP address field for zero. (bp->bp_ciaddr == 0)
-(David suggests we leave this out for now. -gwr)

-.Op Fl i | s
-.Op Fl d Ar level

-.Ar server
-.Sh DESCRIPTION
-The
-.Nm
-utility
-implements an Internet Bootstrap Protocol (BOOTP) server as defined in
-RFC951, RFC1532, and RFC1533.
-The
-.Nm bootpgw
-utility 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.\&
-.Nm )
-on another subnet.
-While either
-.Nm
-or
-.Nm bootpgw
-will forward BOOTREPLY packets, only
-.Nm bootpgw
-will forward BOOTREQUEST packets.
-.Pp
-One host on each network segment is normally configured to run either
-.Nm
-or
-.Nm bootpgw
-from
-.Xr inetd 8
-by including one of the following lines in the file
-.Pa /etc/inetd.conf :
-.Pp
-.Dl bootps dgram udp wait root /usr/libexec/bootpd bootpd /etc/bootptab
-.Dl bootps dgram udp wait root /usr/libexec/bootpgw bootpgw server
-.Pp
-This mode of operation is referred to as "inetd mode" and causes
-.Nm
-(or
-.Nm 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
-.Fl t
-option controls this timeout (see OPTIONS).
-.Pp
-It is also possible to run
-.Nm
-(or
-.Nm bootpgw )
-in "standalone mode" (without
-.Xr inetd 8 )
-by simply invoking it from a shell like any other regular command.
-Standalone mode is particularly useful when
-.Nm
-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
-.Nm
-from within
-.Pa /etc/rc.local ,
-for example.)
-Standalone mode is less useful for
-.Nm bootpgw
-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
-.Fl s
-or
-.Fl i
-option may be used to force standalone or inetd mode respectively
-(see OPTIONS).
-.Sh OPTIONS
-The following options are available:
-.Bl -tag -width indent
-.It Fl a
-Skip ARP table modifications.
-.It Fl t Ar timeout
-Specify the
-.Ar timeout
-value (in minutes) that a
-.Nm
-or
-.Nm bootpgw
-process will wait for a BOOTP packet before exiting.
-If no packets are received for
-.Ar timeout
-minutes, then the program will exit.
-A timeout value of zero means "run forever".
-In standalone mode, this option is forced to zero.
-.It Fl d Ar debug-level
-Set the
-.Ar debug-level
-variable that controls the amount of debugging messages generated.
-For example,
-.Fl d Ns 4
-or
-.Fl d
-4 will set the debugging level to 4.
-For compatibility with older versions of
-.Nm ,
-omitting the numeric parameter (i.e., just
-.Fl d )
-will simply increment the debug level by one.
-.It Fl c Ar chdir-path
-Set the current directory used by
-.Nm
-while checking the existence and size of client boot files.
-This is
-useful when client boot files are specified as relative pathnames, and
-.Nm
-needs to use the same current directory as the TFTP server
-(typically
-.Pa /tftpboot ) .
-This option is not recognized by
-.Nm bootpgw .
-.It Fl h Ar hostname
-Specify the hostname corresponding to the IP address to listen on.
-By default,
-.Nm
-listens on the IP address corresponding to the machine's hostname, as
-returned by
-.Xr gethostname 3 .
-.It Fl i
-Force inetd mode.
-This option is obsolete, but remains for
-compatibility with older versions of
-.Nm .
-.It Fl s
-Force standalone mode.
-This option is obsolete, but remains for
-compatibility with older versions of
-.Nm .
-.It Ar bootptab
-Specify the name of the configuration file from which
-.Nm
-loads its database of known clients and client options
-.No ( Nm
-only).
-.It Ar dumpfile
-Specify the name of the file that
-.Nm
-will dump its internal database into when it receives a
-SIGUSR1 signal
-.No ( Nm
-only).
-This option is only recognized if
-.Nm
-was compiled with the -DDEBUG flag.
-.It Ar server
-Specify the name of a BOOTP server to which
-.Nm bootpgw
-will forward all BOOTREQUEST packets it receives
-.Pf ( Nm bootpgw
-only).
-.El
-.Sh OPERATION
-Both
-.Nm
-and
-.Nm bootpgw
-operate similarly in that both listen for any packets sent to the
-.Em bootps
-port, and both simply forward any BOOTREPLY packets.
-They differ in their handling of BOOTREQUEST packets.
-.Pp
-When
-.Nm bootpgw
-is started, it determines the address of a BOOTP server
-whose name is provided as a command line parameter.
-When
-.Nm 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
-.Nm
-is started it reads a configuration file, (normally
-.Pa /etc/bootptab )
-that initializes the internal database of known clients and client
-options.
-This internal database is reloaded
-from the configuration file when
-.Nm
-receives a hangup signal (SIGHUP) or when it discovers that the
-configuration file has changed.
-.Pp
-When
-.Nm
-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,
-.Nm
-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
-.Nm
-is compiled with the -DDEBUG option, receipt of a SIGUSR1 signal causes
-it to dump its internal database to the file
-.Pa /tmp/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
-.Xr getservbyname 3
-(which normally uses
-.Pa /etc/services ) .
-Two service names (and port numbers) are used:
-.Pp
-.Dl bootps BOOTP Server listening port
-.Dl bootpc BOOTP Client destination port
-.Pp
-If the port numbers cannot be determined using
-.Xr getservbyname 3
-then the values default to bootps=67 and bootpc=68.

-.Os
-.Sh NAME
-.Nm bootptab
-.Nd Internet Bootstrap Protocol server database
-.Sh DESCRIPTION
-The
-.Nm
-file is the configuration database file for
-.Xr bootpd 8 ,
-the Internet Bootstrap Protocol server.
-Its format is similar to that of
-.Xr 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
-.Dl "hostname:tg=value. . . :tg=value. . . :tg=value. . . ."
-.Pp
-where
-.Em hostname
-is the actual name of a bootp client (or a "dummy entry"), and
-.Em 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
-.Em 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.\&
-.Em :tg: ) .
-The currently recognized tags are:
-.Pp
-.Bl -tag -width xxx -compact
-.It bf
-Bootfile
-.It bs
-Bootfile size in 512-octet blocks
-.It cs
-Cookie server address list
-.It df
-Merit dump file
-.It dn
-Domain name
-.It ds
-Domain name server address list
-.It ef
-Extension file
-.It gw
-Gateway address list
-.It ha
-Host hardware address
-.It hd
-Bootfile home directory
-.It hn
-Send client's hostname to client
-.It ht
-Host hardware type (see Assigned Numbers RFC)
-.It im
-Impress server address list
-.It ip
-Host IP address
-.It lg
-Log server address list
-.It lp
-LPR server address list
-.It ns
-IEN-116 name server address list
-.It nt
-NTP (time) Server (RFC 1129)
-.It ra
-Reply address override
-.It rl
-Resource location protocol server address list
-.It rp
-Root path to mount as root
-.It sa
-TFTP server address client should use
-.It sm
-Host subnet mask
-.It sw
-Swap server address
-.It tc
-Table continuation (points to similar "template" host entry)
-.It td
-TFTP root directory used by "secure" TFTP servers
-.It to
-Time offset in seconds from UTC
-.It ts
-Time server address list
-.It vm
-Vendor magic cookie selector
-.It yd
-YP (NIS) domain name
-.It ys
-YP (NIS) server address
-.El
-.Pp
-There is also a generic tag,
-.Pf T Em n ,
-where
-.Em 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
-.Nm bootpd
-first.
-Generic data may be represented as either a stream of hexadecimal
-numbers or as a quoted string of
-.Tn 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:
-.Em cs ,
-.Em ds ,
-.Em gw ,
-.Em im ,
-.Em lg ,
-.Em lp ,
-.Em ns ,
-.Em nt ,
-.Em ra ,
-.Em rl ,
-and
-.Em ts .
-The
-.Em ip ,
-.Em sa ,
-.Em sw ,
-.Em sm ,
-and
-.Em 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
-.Nm bootpd
-to lookup the IP address for that host name using
-.Xr gethostbyname 3 .
-If the
-.Em ip
-tag is not specified,
-.Nm 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
-.Em ht
-tag specifies the hardware type code as either an unsigned decimal, octal, or
-hexadecimal integer or one of the following symbolic names:
-.Em ethernet
-or
-.Em ether
-for 10Mb Ethernet,
-.Em ethernet3
-or
-.Em ether3
-for 3Mb experimental Ethernet,
-.Em ieee802 ,
-.Em tr ,
-or
-.Em token-ring
-for IEEE 802 networks,
-.Em pronet
-for Proteon ProNET Token Ring, or
-.Em chaos ,
-.Em arcnet ,
-or
-.Em ax.25
-for Chaos, ARCNET, and AX.25 Amateur Radio networks, respectively.
-The
-.Em ha
-tag takes a hardware address which may be specified as a host name
-or in numeric form.
-Note that the numeric form
-.Em must
-be specified in hexadecimal; optional periods and/or a leading '0x' may be
-included for readability.
-The
-.Em ha
-tag must be preceded by the
-.Em ht
-tag (either explicitly or implicitly; see
-.Em tc
-below).
-If the hardware address is not specified and the type is specified
-as either "ethernet" or "ieee802", then
-.Nm bootpd
-will try to determine the hardware address using
-.Xr ether_hostton 3 .
-.Pp
-The hostname, home directory, and bootfile are
-.Tn ASCII
-strings which may be
-optionally surrounded by double quotes (").
-The client's request and the
-values of the
-.Em hd
-and
-.Em 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
-.Em bf
-option is specified its value is copied into the reply packet.
-If the
-.Em 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
-.Em bs Ns =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
-.Xr tftpd 8
-provide a security feature to change their root directory using
-the
-.Xr chroot 2
-system call.
-The
-.Em td
-tag may be used to inform
-.Nm bootpd
-of this special root directory used by
-.Nm tftpd .
-(One may alternatively use the
-.Nm bootpd
-.Fl c Ar chdir
-option.)
-The
-.Em hd
-tag is actually relative to the root directory specified by the
-.Em td
-tag.
-For example, if the real absolute path to your BOOTP client bootfile is
-.Pa /tftpboot/bootfiles/bootimage ,
-and
-.Nm tftpd
-uses
-.Pa /tftpboot
-as its "secure" directory, then specify the following in
-.Pa bootptab :
-.Pp
-.Dl :td=/tftpboot:hd=/bootfiles:bf=bootimage:
-.Pp
-If your bootfiles are located directly in
-.Pa /tftpboot ,
-use:
-.Pp
-.Dl :td=/tftpboot:hd=/:bf=bootimage:
-.Pp
-The
-.Em 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,
-.Nm bootpd
-will tell the client to perform TFTP to the same machine
-.Nm bootpd
-is running on.
-.Pp
-The time offset
-.Em to
-may be either a signed decimal integer specifying the client's
-time zone offset in seconds from UTC, or the keyword
-.Em auto
-which uses the server's time zone offset.
-Specifying the
-.Em to
-symbol as a boolean has the same effect as specifying
-.Em auto
-as its value.
-.Pp
-The bootfile size
-.Em bs
-may be either a decimal, octal, or hexadecimal integer specifying the size of
-the bootfile in 512-octet blocks, or the keyword
-.Em auto
-which causes the server to automatically calculate the bootfile size at each
-request.
-As with the time offset, specifying the
-.Em bs
-symbol as a boolean has the same effect as specifying
-.Em auto
-as its value.
-.Pp
-The vendor magic cookie selector (the
-.Em vm
-tag) may take one of the following keywords:
-.Em auto
-(indicating that vendor information is determined by the client's request),
-.Em rfc1048
-or
-.Em rfc1084
-(which always forces an RFC1084-style reply), or
-.Em cmu
-(which always forces a CMU-style reply).
-.Pp
-The
-.Em hn
-tag is strictly a boolean tag; it does not take the usual equals-sign and
-value.
-Its presence indicates that the hostname should be sent to RFC1084
-clients.
-.Nm 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
-.Em tc
-(table continuation) mechanism.
-Often, the template entry is a dummy host which does not actually exist and
-never sends bootp requests.
-This feature is similar to the
-.Em tc
-feature of
-.Xr termcap 5
-for similar terminals.
-Note that
-.Nm bootpd
-allows the
-.Em tc
-tag symbol to appear anywhere in the host entry, unlike
-.Pa termcap
-which requires it to be the last tag.
-Information explicitly specified for a
-host always overrides information implied by a
-.Em tc
-tag symbol, regardless of its location within the entry.
-The
-value of the
-.Em 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
-.Em tc .
-This can be done using the construction
-.Em tag Ns @
-which removes the effect of
-.Em tag
-as in
-.Xr termcap 5 .
-For example, to completely undo an IEN-116 name server specification, use
-.Em :ns@:
-at an appropriate place in the configuration entry.
-After removal
-with
-.Em @ ,
-a tag is eligible to be set again through the
-.Em 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.

-.Op Fl f Ar config\-file
-.Op Ar client\-name ...

-.Sh DESCRIPTION
-The

-utility builds the
-.Em "Extension Path"
-files described by
-.%T "RFC 1497"
-(tag 18).
-If any
-.Ar client\-name
-arguments are specified, then

-compiles the extension files for only those clients.
-.Sh OPTIONS
-.Bl -tag -width indent
-.It Fl c Ar chdir\-path
-Sets the current directory used by
-.Nm
-while creating extension files.
-This is useful when the
-extension file names are specified as relative pathnames, and
-.Nm
-needs to use the same current directory as the TFTP server
-(typically
-.Pa /tftpboot ) .
-.It Fl d Ar debug\-level
-Sets the
-.Ar debug\-level
-variable that controls the amount of debugging messages generated.
-For example,
-.Fl d Ar 4
-will set the debugging level to 4.
-.It Fl f Ar config\-file
-Set the name of the config file that specifies the option
-data to be sent to each client.

-.Sh NAME
-.Nm bootptest
-.Nd "send BOOTP queries and print responses"
-.Sh SYNOPSIS
-.Nm
-.Op Fl f Ar bootfile
-.Op Fl h
-.Op Fl m Ar magic_number
-.Ar server\-name
-.Op Ar template\-file
-.Sh DESCRIPTION
-The
-.Nm
-utility sends BOOTP requests to the host specified as
-.Ar server\-name
-at one\-second intervals until either a response is received,
-or until ten requests have gone unanswered.
-After a response is received,
-.Nm
-will wait one more second listening for additional responses.
-.Sh OPTIONS
-.Bl -tag -width indent
-.It Fl f Ar bootfile
-Fill in the boot file field of the request with
-.Ar bootfile .
-.It Fl 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.
-.It Fl m Ar magic_number
-Initialize the first word of the vendor options field with
-.Ar magic_number .
-.El
-.Pp
-A
-.Ar template\-file
-may be specified, in which case
-.Nm
-uses the (binary) contents of this file to initialize the
-.Em options
-area of the request packet.

- * bootptest.c - Test out a bootp server.
- *
- * This simple program was put together from pieces taken from
- * various places, including the CMU BOOTP client and server.
- * The packet printing routine is from the Berkeley "tcpdump"
- * program with some enhancements I added. The print-bootp.c
- * file was shared with my copy of "tcpdump" and therefore uses
- * some unusual utility routines that would normally be provided
- * by various parts of the tcpdump program. Gordon W. Ross
- *
- * Boilerplate:
- *
- * This program includes software developed by the University of
- * California, Lawrence Berkeley Laboratory and its contributors.
- * (See the copyright notice in print-bootp.c)
- *
- * The remainder of this program is public domain. You may do
- * whatever you like with it except claim that you wrote it.
