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 -An example -.I /etc/bootptab -file follows: -.PP -.nf - # Sample bootptab file (domain=andrew.cmu.edu) - - .default:\\ - :hd=/usr/boot:bf=null:\\ - :ds=netserver, lancaster:\\ - :ns=pcs2, pcs1:\\ - :ts=pcs2, pcs1:\\ - :sm=255.255.255.0:\\ - :gw=gw.cs.cmu.edu:\\ - :hn:to=-18000: - - carnegie:ht=6:ha=7FF8100000AF:tc=.default: - baldwin:ht=1:ha=0800200159C3:tc=.default: - wylie:ht=1:ha=00DD00CADF00:tc=.default: - arnold:ht=1:ha=0800200102AD:tc=.default: - bairdford:ht=1:ha=08002B02A2F9:tc=.default: - bakerstown:ht=1:ha=08002B0287C8:tc=.default: - - # Special domain name server and option tags for next host - butlerjct:ha=08002001560D:ds=128.2.13.42:\\ - :T37=0x12345927AD3BCF:\\ - :T99="Special ASCII string":\\ - :tc=.default: - - gastonville:ht=6:ha=7FFF81000A47:tc=.default: - hahntown:ht=6:ha=7FFF81000434:tc=.default: - hickman:ht=6:ha=7FFF810001BA:tc=.default: - lowber:ht=1:ha=00DD00CAF000:tc=.default: - mtoliver:ht=1:ha=00DD00FE1600:tc=.default: - -.fi -.SH FILES -/etc/bootptab - -.SH "SEE ALSO" -.br -bootpd(8), tftpd(8), -.br -DARPA Internet Request For Comments RFC951, RFC1048, RFC1084, Assigned Numbers |
