Hello,

I have some strange network problem: i can ping(icmp
works), i can arping(arp works), my dns works, btw routes also looks ok,
but then I try to open any site all i get is "request sent" message
from links, or connection broken to
x.x.x.x ... from conquer, and opera just displays empty pages,
and i dont think i have firewall(I'am quite new to
gentoo). Internet from windows and from livecd works without problems.
My best gues is it`s something wrong with tcp, maybe someone had a
similar problem
and could share their experience?
Thanks in advance. Sorry for english:)

Hi,

Can you give us a "route -n" plus your ifconfig settings?

If you've got wireshark or tcpdump, what packets do you capture?

	Hello,

Ok - just to clarify, you are sucessfully pinging the webserver you want
to contact by name - is that correct? If so, that indicates that arp,
dns and routing are all ok.

	 
	 but then I try to open any site all i get is "request sent"
message from links, or connection broken to  x.x.x.x ... from conquer,
and opera just displays empty pages,
	and i dont think i have firewall(I'am quite new to   entoo).

The only time i have seen this sort of thing is when there is a firewall
or MTU issue, but that would be unlikely here. Next stop is to run
netstat or a sniffer to see what's happening, but send the ping output
here first.
 
Rgs,
