kubuntu help

well on my older desktop i recently added a dual boot with kubuntu, so now it has kubuntu 7.10 and windows xp (im thinking sp2). well im hoping its not sp2, because of the dreaded raw-sockets kill. so i wrote a simple syn flooder with kate and compiled with gcc, when, to my suprise, didn't work. the following socket() call failed and produced the perror("socket()") call.

s = socket(PF_INET, SOCK_RAW, IPPROTO_RAW);

im afraid that this is because windows has already messed with the networking drivers and disabled raw sockets.
if anyone here has some insight, please help

edit:
i believe nmap does work (port scanning atleast). im severely confused.

Re: kubuntu help

drivers would be specific to the OS running at the time...

yeah i shortly realized that after i pressed submit. disregard the whole post, i just needed to supply root password again by appending sudo infront of it :P

Not sure, but I'd guess it requires root privileges, hence the need for sudo.

[edit:] actually, this makes sense. Giving raw network access seems (to my slightly buzzed mind, had a couple drinks this evening) like a very possible security risk, hence the need for - as Vista so well puts it - elevated privileges. Requiring anything using raw sockets to either run as root or call setuid() to get root privileges seems like a feasible requirement.

Re: kubuntu help

jimbo and jabo, in windows xp sp2 and above, raw sockets are disabled at driver level.

EDIT:
sorry for the bump :(

Even so, the problem was occurring in Kubuntu, wasn't it? :icon_wink:
