Re: [NV-L] Netview not discovering

["Robson Souza" <robsoneng@gmail.com>]

Hi James,

 

Thx for your fast replying.

 

Yes, that's a new instalation, but we don't use names for the routers in our network. There are only routers ip addresses in the seed file. In any way, we just use name resolution for our servers and it's OK.

 

As you advised, we checked the machine and the Netview SNMP communities. There was really a difference between one and another one. After that, we have configured the both with the same community. But there have not been some effects.

 

The netmon trace was enabled with -1 option already. As I said, I can see in that file a lot of ping attempts to all of routers I have put in the seed file. But those pings does not happen effectively through a sniffer installed in the same machine.

resolve correctly, both forward (hostname to IP address) and back (IP
address to hostname).  I would also check, using snmpconf (you can invoke
that from the command line), that either the SNMP community string that you
have for the global default is the same as the one as the NetView machine
itself, or that you have a separate entry for the NetView machine and for
127.0.0.1 which specify the correct community name to use.  netmon gets
very confused when it cannot talk to SNMP on its own machine.

If that's no help, then you can try looking more closely at the netmon
trace.  You did not indicate whether you just examined the file or set some
options to get more information.  You can turn on the full netmon trace
from the command line with "netmon -M -1" and watch what happens as he
runs.  You can turn it off again with "netmon -M 0".  If you can't get any
clues from the netmon trace, then I would open a problem to IBM Support,
since the netmon trace is not really designed as a user-friendly interface.
It's most useful to a netmon specialist, particularly one who has access to
the code.

Hope this helps,

Hi all,

We have got the following problem:

We have just installed Netview 7.1.4 with FP04 in a Windows 2000 Server.
After the instalation, we expected that the discovery process started to
find out our network but it does not occurs.
The seed file is OK and it has a lot of routers included in it.
I have enabled the netmon trace in order to see if the netmon is trying to
discover the network through the ping mechanism. The netmon.trace file
denounces that its trying to ping each of router IP.
To be certain about that, I enabled a sniffer to capture the ICMP packets
related above. For my surprise, there was not any ICMP packet trying to get
out through the network interface.
I have tested the Netview ping utility to ping the routers: it is working.
And I have tested the ping through Windows CLI, it is OK too.

Does anybody have an idea to solve this problem?

Robson
