Internet boot protocol server
|
You must be root to start this server. |
bootpd [-dpsT] [-t timeout] [configfile]
Neutrino
- -d
- Increase the level of debugging output (-dd to be more verbose).
- -s
- Run in standalone configuration. Use this option if bootpd
is not being started by inetd (e.g. when started in a
sysinit file).
- -T
- Do not remove unknown vendor-specific information. The default is to remove the
vendor-specific section of the response packet if unknown, or remove unknown options if the
vendor is known.
- -t timeout
- When not running standalone, this option specifies the time
in minutes that bootpd will wait for the next
boot request before exiting to conserve system
resources. When the next boot request arrives, inetd
will restart bootpd. If you don't want
bootpd to exit, give timeout a value of 0.
The default timeout is 15 minutes.
- configfile
- Specify a configuration file (the default file is
/etc/bootptab).
The bootpd server implements an Internet Boot
Protocol server as defined in RFC 951 and
RFC 1048.
It's normally invoked by the
inetd
daemon via the following line in the
/etc/inetd.conf file:
bootps dgram udp wait root /usr/sbin/bootpd bootpd
This method conserves system resources: bootpd is started only
when a boot request arrives, and if it doesn't receive another boot request
within fifteen minutes (default) of the last one received, it exits.
You can use the -t option to specify a different timeout value
in minutes (e.g. -t 20). A timeout value of zero means forever.
Rather than wait for a boot request, bootpd can
be started independently of inetd.
This is probably the desired mode of operation for
large network installations with many hosts.
|
When using the -s option, bootpd and
inetd may compete for the same port. Make sure to
comment out the bootps entry in the
/etc/inetd.conf file. In this case, the
-t option has no effect, because bootpd
never exits. |
Upon startup, bootpd first reads its
configuration file,
/etc/bootptab, and then
begins listening for BOOTREQUEST packets.
The server rereads its configuration file when it receives a
hangup signal (SIGHUP) or when it receives a
bootp request packet and detects that the file
has been updated. Hosts may be added, deleted, or modified
when the configuration file is reread.
- /etc/bootptab
- Boot protocol server configuration file.
- /etc/services
- Service name database.
The bootpd daemon requires the libsocket.so
shared library.
