netmon won't start

   Env: AIX 4.1
        Netview 4.1

   Problem:

Customer is having trouble starting the netmon daemon.  It is
giving him the following error:

  cannot communicate with snmp via loopback

   Solution: 

I had the customer do the following:

  host loopback
    loopback not found.

I had the customer go into the /etc/hosts file and add the following
line:

  127.0.0.1 localhost loopback

I then had the customer do the following:

  snmpwalk -c public loopback system
    This came back with the system information, so we can access
    the system via the public community name.

I had the customer cut the following line from his /etc/netnmrc file
and use it on the command line:

  /usr/OV/security/cmds/snmpget_unsecure -t 3 -r 2 `hostname`
  .1.3.6.1.2.1.1.1.0
    This just came back to a prompt.  We got no errors, and no
    messages.

  hostname
    This came back blank.

I had the customer go into "smitty tcpip" and set all of his minimum
configuration information, so that the hostname was defined, and we
ran the snmpget command again.  This time it came back with
information.  When we tried to start netmon, however, it still gave
the same error.  I had the customer do the following:

  xnmsnmpconf &

We then looked for 127.0.0.1 in this window anywhere, but it did not
exist.  The global default, however, was set to a community name of
"promise".  I had the customer go into his /etc/snmpd.conf file, and
add the following line:

  community promise 127.0.0.1 readWrite

We then did the following:

  stopsrc -s snmpd
  startsrc -s snmpd
  ovstart netmon

This worked, and the customer was able to pull up the graphical
interface.
   Next Action: Customer agrees to close call.
