UNIX BOOTP
If you are running UNIX, try the following methods
with the BOOTP server (check the documentation for
your particular UNIX flavor).
• Verify the BOOTP server has reread the “/etc/
bootptab” file when the new entry was added. If
the BOOTP server was running when you added
the new entries, the server might not have reread
the new bootptab file. Try sending the SIGHUP
signal to the running BOOTP server. For example,
kill -HUP < process id of bootpd > tells it to reread
“/etc/bootptab”. Most BOOTP servers support this
option. Check your local BOOTP documentation.
If this does not work, restart the BOOTP server
(kill and restart the process).
• Some BOOTP servers will write their internal
bootptab tables to a file when they receive a
SIGUSR1 signal. You can check this file to verify
the hardware and IP address are correct. You can
use the kill command to send signals. For
example,
kill -USR1 < process id of bootpd >.
Check your documentation for more information.
• Check the system’s syslog file. Some BOOTP
servers will write error messages into the syslog
file.
Example:
Sep 6 14:38:43 bootpd[17565]: hardware
address not found: 004068175042
This message appears when the BOOTP server
received a request from a device not in its internal
bootptab tables.
