Thread-topic: SNMP problems with Red Hat 4 and NetView 7.1.5
This customer (doe.gov) is very worried about security.  My system
support counterpart is required to develop the minimum version of Red
Hat 4 (no unneeded packages) with the latest possible fixes.  A  problem
occurred which was manifested as an inability of Netmon to connect to
SNMP.  The Netmon trace showed this message: 

        Cannot communicate with SNMP Agent via loopback address
(; it is
        either not running or has been configured with a community name
        from that configured into Tivoli NetView for this system. If a
community name has
        been configured into the SNMP Agent, that community name must be
        via xnmsnmpconf and /usr/OV/conf/ovsnmp.conf for address 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 NetView configuration menu
That was not the problem.  Here is the note sent when he isolated the
problem.  He rebuilt the system and added packages and patches until we
got the failure then backed them out to verify the fix. 

        The packages which apparently caused us the problems were the
        and net-snmp-libs. It might be just one of them, but I removed
        re-installed them in tandem.

        Working version 

        The problem came with these bug fix packages.
