bootpef(1Mtcp)


bootpef -- BOOTP extension file compiler

Synopsis

bootpef [ -c chdir_path ] [ -D debug_level ] [ -f config_file ] [ client_name ]

Description

Internet Bootstrap Protocol (BOOTP) BOOTREPLY packets include a fixed-length (64 bytes) field in which vendor-extension information is sent. This information may need to exceed this limit. The bootpef command provides a way around this limitation by compiling the vendor-extension information into a file. The name of the file, called an ``extension path'', is sent in the vendor-extension field of the BOOTREPLY packet. When the BOOTP client requests and receives this file, it interprets the file as it would the vendor-extension field.

When run without options, bootpef reads the default configuration file /etc/bootptab looking for entries containing the ef tag. See bootptab(4tcp). When bootpef finds such an entry, it compiles the vendor-extension information of that entry into the file specified with the ef tag. If the file pathname begins with a slash (/), bootpef interprets the pathname to be an absolute pathname. If the file pathname does not begin with a slash, bootpef creates the pathname relative to its current directory.

If any client_name arguments are specified, then bootpef searches the database configuration file for a hostname that matches client_name and compiles the extension files for only those client entries. When no client_name arguments are specified, bootpef compiles all client entries with an ef tag.

Options


-c chdir_path
Sets the current directory used by bootpef while creating extension files. This is useful when the extension file names are specified as relative pathnames and bootpef needs to use the same current directory as the TFTP server (typically /tftpboot).

-D debug_level
Sets the debug_level variable that controls the amount of debugging messages generated. For example, ``-D1'' or ``-D 1'' will set the debugging level to 1. Recognized values are 0, 1, 2, and 3 or greater. Zero generates no messages and 1 to 3 generate increasing amounts of messages. Specifying an integer over 3 has the same result as specifying 3.

-f config_file
Allows specification of a different database configuration file than the default /etc/bootptab.
