Error message in syslog.log

Hi,

Running HP-UX 11.0 as DHCP server. and noticed the following messages appeared in the syslog.log file. What could be the causes for such messages?
Mar 14 11:09:02 dhcp02 bootpd[12901]: select timed out, no echo came back.
Mar 14 11:25:09 dhcp02 bootpd[12901]: could not add hardware address: 0400607655F2

thank you.

Re: Error message in syslog.log

dhcp02 bootpd[12901]: select timed out, no echo came back.

The message are purely informational and are useful in debugging.

You can get rid of them by installaing the latest DHCP/bootpd patches as below:

PHNE_19241 bootpd(1M)/DHCP cumulative patch

Re: Error message in syslog.log

These messages are informational messages into the syslog.

There was a request for boot from the remote machine/device to this dhcp server and this remote machine ip was not present in the configuration file /etc/bootptab.

The /etc/syslog.conf file would have also
*.info configured to the logged into syslog.

This is just an information message.

Re: Error message in syslog.log

Thank you.

I just noticed that when there was "dhcp02 bootpd[12901]: could not add hardware address: 0400607655F2" message appeared in the syslog.log, it seemed that DHCP client did not got address. Is this error message indicating an error?

2nd, I have checked patch you mentioned, I have run "what /usr/lbin/bootpd" and it seems that I have patch (PHNE_19241) installed already. If so, is it still normal that I got this message in the syslog.log?

Re: Error message in syslog.log

Hi Ji,

IF you're are not supplying remote boots to other devices then you may wish to turn off bootp by commenting out the following line in /etc/inetd.conf

bootps dgram udp wait /usr/lbin/bootpd bootpd

And then run

inetd -c

Then it will no longer respond to remote boot requests.

HTH,
Jeff

Re: Error message in syslog.log

Hi Jeff,

Basically, I am running the server as DHCP server which provides IP address to clients in a few IP subnet.

But, no machine will boot from this server.

Do you mean that I could turn off bootpd but still run the server as DHCP server?

thank you.

Re: Error message in syslog.log

No, bootp and dhcp are using the same daemon and almost the same protocol...

How do you split MAC addresses over the seperate subnets?

Re: Error message in syslog.log

If u want to use your DHCP server to assign ip to nodes in the seperate network you need to add relays. this link may help to have a better understanding

Don't give up. Try till success...

Re: Error message in syslog.log

The bootp rely is done by the router connecting different network. So, the DHCP server should know which address to assign. But now, I am more interested to know what the meaning of thoes messages.

Thank you.
