DoS attack from within a Home Network
Posted on 2004-04-21
We have had a home network behind a NetGear router into a Cable Modem for about 2 years without incident. Last week the network appearred to go down. Reset router and "down" again in about 10 minutes. Replaced router with 2 others - same problem. Replaced Cable modem - same problem. Noticed some machines generating a large number (>50,000) packets when "nothing" running (no IE, Outlook, etc). When these machines are taken off network, other machines access the internet normally. Do I have a DoS virus on these machines? BTW, when I attach one offending machine directly to cable modem, all is well - no excessive packets, etc.
