Re: [nv-l] Expired ping message in netmon.trace

[Mike Pearson <pearsom@us.ibm.com>]

Dennis:
        This
just means that netmon has not received a reply back from the source.  It
could mean a number of things.  The best way to find out what had
happened to the ping that was sent out is to run sniffer or ethereal and
match up the sequence number from the netmon trace with that found in the
ethereal/sniffer output.  I have usually found that I do not get a
reply back from the node I sent the ping to.  Although I have been
suprised at times.  
Please note both netmon trace and ethereal/sniffer
must be run at the same time.

Subject	[nv-l] Expired ping message in netmon.trace

Hi list, my netview was working till yesterday  afternoon
then it stops to polling nodes for status. It works normal for receive
 traps and so on, but the netmon seems to be dead. I enabled the netmon
trace  with mask 10 (netmon -M 10) and in the file netmon.trace it´s
recorded the  following message:
 
05/01/2005 14:00:02 expired ping to 10.10.0.1 ( )  seqnum
= 4001 ident = 4744
05/01/2005 14:00:03 expired ping to 10.10.0.2 ( )  seqnum
= 4002 ident = 4744
.
.
.n messages
 
On the programmer´s reference guide i read about  the
option -q number that increase the ICMP queue size for ping. I though that
 if i put this parameter in the netmon.lrf and then run ovobjadd it
will stop  with the message but the problem goes on.
 
Does anyone have ideia about how to fix this  problem?

Thanks in advance,
