Hi Guys, wonder if you can help - its probably a fairly straightforward tech question. My ubuntu box is connected to a 2mb line direct through cable modem - no router. My connection seems to be getting bombarded with incoming data (ping flood?) and i have no bandwidth at all.

ifconfig gives me my IP, and i reckon i need to get a new one before this will stop, but i have turned my modem off overnight and it still will not release the IP back into the pool, and assign me a new one upon reconnection.

How do i manually drop my ip, and pick up the next available one, with terminal?

My ISP has been absolutely useless to help, as noone there can use linux or knows anything about it. They can see and ping the modem, so as far as they are concerned (or care) its working. And its not. At all. personally i think im being DOS'd.

Anyone help?

You can change ip typing :
To view you net card parameters type : ipconfig -a

But i don't think it is a good idea... If it is net bought from any firm, it changing ip can cause problems with Internet...

Better check who is attacking you and block packets from him on firewall..

aaaaaa sorry....
So you can type ip from keyboard. If you want next from DHCP server.. DHCP cant give you other. But maybe it will work . type :
It may work, but doest have to

you mean ifconfig, not ipconfig?

yes..... Sorry..
