Kernel 2.6.17 and 2.6.18-3-K7 network problem
Hi all, I posted the question below to debian-user ... maybe nobody experienced my same issue. How can I contribute to eventually solve? Which other information are necessary in order to focalize the problem? I want to ask if somebody experienced the same problem I have with etch installation and in general with kernel 2.6.17 and 2.6.18 on AMD K7. The computer where I tried has 2 network cards, I connect only 1 card and it receives the IP address. I experienced the problem installing etch using a businesscard, using knoppix 5.0.1 (use kernel 2.6.17) and upgrading from sarge (kernel 2.6.8) to etch (kernel 2.6.18). In the last case, with the same installation if I chose kernel 2.6.8 I have no network problem (but X does not work :( ). If I choose the kernel 2.6.18 X is OK but I am not able to reache many sites. I can navigate very few sites example: www.google.com and www.mozilla.org. Using ethereal seems that the HTTP request go out (i.e. GET / ) but the ACK packet does not ask the next packet number in other words seems that the GET request never reched the final site. I tryied to reduce the MTU but was unsuccesful. Last details: the network card is the Realtek Regards anlater anlater http://studioinglaterza.blogspot.com/ __ Do You Yahoo!? Poco spazio e tanto spam?

Best regards Hendrik!!! Most probabily the provider's router is buggy but it solved the problem. The solution was that reported by article pointed by you: In the mean time, anybody running a current kernel who is having trouble connecting to a needed site can work around the problem with a command like: echo 0 > /proc/sys/net/ipv4/tcp_default_win_scale or by adding a line like: net.ipv4.tcp_default_win_scale = 0 to /etc/sysctl.conf. anlater http://studioinglaterza.blogspot.com/ __ Do You Yahoo!?
