Hi, I have a router which is maintained by our ISP. They have given us to monitor it by using MRTG. It is okay. But it only shows incoming and outgoing traffice. It does not say wherther is TCP or UDP or ICMP. It just shows in and out.That's it. But, I want to monitor this router ? Can you tell me a good pkg for it ? router has a snmp commiunity password . Ido not know it. My ISP does not give it either. Can you help me accoring to my condition soon? -- Thank you Indunil Jayasooriya -------------- next part -------------- An HTML attachment was scrubbed...
