I hope I have posted this in the correct forum as I wasnt sure which is the best place to put it. (please move if incorrect)
I think I have a problem with someone DDOS'ing or attacking my internet connection "Think" not 100% but here’s the story.
Connected to my Virgin media internet is my Linksys wireless g router and connected to that are 2 wired PC's a wired xbox360 and 3 wireless laptops.
2 of the laptops belong to my twin sons who like to play runescape online whilst chatting to their (so called) mates on team speak and ventrillo.
Apparently in one of the ventrillo rooms one of my sons goes in there is an Indian lad called Izah (or something like that) who says he can ddos peoples internet.
The other night my son had a "heated discussion" with this Indian lad and within 5 minutes our internet was on and off several times within a 20 minute period.
I am wondering is it possible for this Indian lad to do this? I know when you enter ventrillo chat, admins or mods can retrieve you IP address and that’s how this lad says he does it.
Oh and by the way yes I have told my son NOT to go back into this room where the Indian lad is either a mod or admin.
But I need to know are there any measures I can take to prevent this happening again and is it in fact a ddos that is happening?
I checked my modem event log and there are some strange readings that go on the line of
Mon Dec 27 10:46:17 2010 critical (3) DHCP WARNING - non-critical field invalid response
and this appears a few times. Is this a result of the attack?
Is it worth me contacting the ISP (virgin) or some other authorities?
