/usr/adm/syslog: hardware address not found

Michael Bluemm — Mon, 28 May 2001 13:37:18 GMT

Hi,
every minute I get 2 error messages in /usr/adm/syslog:
bootpd[12988]: hardware address not found: 524153206071 and
hardw.addr. not found:0030840E9033
How can I find out, which hardware is meant?
How can I disable this hardware, if possible/necessary?
Thank you, bye
Michael

Hi,

If you are not booting any bootp devices from this server/workstation then the simplest solution would be:
1) vi /etc/inetd.conf
Find the bootps antry and comment it out by placing a '#' at the beginning of the line.
2) inetd -c to force a re-read of the config file.

These messages do no harm but they are annoying.

Hi Clay,

my bootps entry is:
dgram udp wait root /etc/bootpd bootpd
- is this ok?

These entries,
could they belong to an old workstation?
to an old printer?
Where could I find out?
Thank you for your help

Michael,
You can look up the vendor code for the first 6 digits and that will tell you most likely who the vendor of the devices broadcasting the boot requests:
http://ftp.cavebear.com/CaveBear/Ethernet/vendor.html
You can also capture these devices on a sniffer trace most easily. Contact your network LAN support technicians to have that done. If you're that person, and do not have access to a sniffer, you can always attempt to capture a nettl trace while the broadcasts are going on.
Check out the IT Resource Center documents
HOW TO TAKE A NETWORK TRACE ON HP-UX KBRC00001272
or
HOW TO TAKE A NETWORK TRACE ON HP- KBAN00000068
Hope this helps,

Hi Micheal,

Yes, that's the line to comment out if you are not a bootp server. You can use this website http://standards.ieee.org/regauth/oui to get a listing mapping the first 6 digits of a MAC address to a manufacturer. That should help point you to the equipment. You should note that these guys are broadcasting to your network for boot instructions and nobody is responding.

Good Hunting, Clay

look at /etc/bootptab for an entry with that MAC address, anyway it is a common error displayed if rbootd is running in the bootp server.

You could first check that you have the latest bootp* patch for your OS version (which is not stated),
Or you could try this:

vi the /etc/syslog.conf file and change the line that reads :

*.info,mail.none /usr/adm/syslog

to

*.warning,mail.none /usr/adm/syslog

then do:
/sbin/init.d/syslogd stop
/sbin/init.d/syslogd start
