RE: Problem with netmon

["James Shanks" <jshanks@us.ibm.com>]

Stephen -

If you just type "ping <ip_address> or ping <hostname> from the command 
line and it fails, that is NOT a NetView problem.
Ping by itself is a TCP/IP primitive and part of the TCP/IP stack 
maintained by AIX as part of the base OS.
If ping is failing then you have some kind of basic TCP/IP configuration 
issue.
Sorry but problems of that fundamental a level are not my area of 
expertise. 
Best I can suggest is that you use SMIT to check the config and restart 
your interface if it is down.

James,
 
I have some good news and some bad news.
 
Good news is the stopsrc/startsrc worked to get netmon up.
 
Bad news is I cannot ping any device off the local subnet. The router is 
OK,
I can ping the devices from an NT desktop pc, but when I ping from my
Netview 
box I get ..

Have you tried just stopping and restarting snmpd?  The MIB message is
usually NOT the problem unless you don't have the default set which 
includes
rfc1213-MIB-II loaded. 

Do "stopsrc -s snmpd", wait a few seconds, then "startsrc -s snmpd" and 
see
if it restarts.  Count to ten and ovstart netmon. 

Doesn't help?  then check that your /etc/hosts has these two entries 
first: 
127.0.0.1   loopback localhost 
<your_ip_address>   <your_hostname> 
and that xnmsnmpconf has entries for BOTH of these if you are not using
"public" as the default community name. 
Try an snmpwalk of your own box and see if it works (don't specify the
community --let it default).  If it does, then netmon should start. 
If it doesn't then I don't know what to tell you.

Greetings to all,

First, I may be a little cranky this morning since our Netview
box went down after an extended power outage, so I hope I wasn't
too harsh with David about his autoresponder.  :)

AIX 4.3 and netview 5.2

(I know, I know, upgrade!!!)

Anyway, this has happened in the past and all I have ever done
is restore to solve the problem.

If the machine has an abrupt shutdown, netmon will not start.
I get the following message ...

____________________________________________________________________-
Cannot communicate with SNMP Agent via loopback address (127.0.0.1); it is
either not running or has been configured with a community name different
from that configured into TME 10 NetView for this system. If a community
name ha
s
been configured into the SNMP Agent, that community name must be 
configured
via xnmsnmpconf and /usr/OV/conf/ovsnmp.conf for address 127.0.0.1 as well
as for the hostname or IP address of this system.
Or, the /usr/OV/conf/snmpmib and /usr/OV/conf/snmpmib.bin files are
corrupted
and need to be rebuilt using the
Maintain->Rebuild MIB binary file with installation MIB defaults
option in smit

When I tried to rebuild the files, it *really* screwed things up.

Any ideas?
