You must run the SNMP daemon on the target machine. It cannot, by default, discern traffic destinations, it only looks at totals passing through the network interfaces (IIRC ifInOctets, ifOutOctets, and ifInerrors and IfOutErrors). The OP did not specify the OS's running on the boxes of interest, but I suspect that if a SNMP daemon exists for non-Linux OS's the data would be available to MRTG. As stated/implied by others the most non-intrusive method would be to let MRTG query a managed switch. The D-Link router is not managed (AFAIK). Bob...
