Looks like you just don’t have the hardware for it at the moment. You could install SNMP onto your windows boxes -- they can support it, and it is in the standard Windows distro but not installed by default. That might be your best bet as it costs nothing and will allow SNMP queries of traffic using normal MRTG. Alternatively, upgrade your switch to an intelligent one that supports SNMP. That would be the easiest solution, as you can then graph each port as each port corresponds to one device. Of course this will cost. Since you don’t have control over your router, you have nothing you can do there. In any case, you wouldn’t be able to split the traffic count by source unless it had RMAN or you had linux command-line access. Also, since you have an unmanaged switch, you cannot configure a spanning port, so a network sniffer is likely pointless as it will not show you all the packets. You could place a linux box in series with your router on the switch port, and sniff the traffic as it passes through, but that would require a lot of awkward work. I'd go with installing SNMP on the windows boxes (if not many of them) or upgrading your switch to a proper managed one (if you have the $) Steve Steve Shipway ITS Unix Services Design Lead University of Auckland, New Zealand Floor 1, 58 Symonds Street, Auckland Phone: +64 (0)9 3737599 ext 86487 DDI: +64 (0)9 924 6487 Mobile: +64 (0)21 753 189 Email: [email protected] Please consider the environment before printing this e-mail
