Just commented out the ecn entry. btw, as the sysctl man page reads, with -e it should be silent, and in fact it is if I try it after boot. But in boot sequence it spits the error message... -- J.A.

Could you do an 'if [ -f /proc/sys/net/ipv4/tcp_ecn ]' or similar ? Although mdk kernels are built with ecn, think on people can build its own kernels...

Re: [Cooker] weird internet stuff
Juan, Could you enable ECN in the alpha .config file for the next kernel (just to keep it a bit consitent)? Thanks Stefan PS: My girlfriend was complaining that she couldn't reach http://www.appledaily.com/ from my Linux box, now (with -25mdk) it's fixed though --> I guess it was ECN ;-) > > "vincent" == Vincent Meyer <[EMAIL PROTECTED]> writes: > > vincent> Hello, > vincent> Can anyone think of a reason why one would only be able to look at some web > vincent> sites and not others ?

Re: [Cooker] weird internet stuff
Juan - Thank you for explaining the problem. Is this something that in the future we can expect more and more sites to properly support? V.
RE: [Cooker] weird internet stuff
For everyone's info (if you like reading this stuff), there is further explanation of the problem here: http://www.tux.org/lkml/#s14-2 (with links in that text to the appropriate RFCs on the subject). As explained in the text, if you have access to or know the admin who has access to the bad router, there are patches from the vendors to bring them up-to-date to work correctly with ECN. If nothing else, try emailing the webmaster of the site. They may not even know about the problem (especially if it is a Windows only site, since it will probably be another few YEARS before MS gets around to even reading the RFCs on the subject (much less find a way to "extend and embrace" it)).

Hi Easy solution: echo 0 > /proc/sys/net/ipv4/tcp_ecn (you can put it in /etc/sysctl.conf) You can also update to 24/25mdk kernel. The problem is ECN, a new standard to improve cogestion detection in networks. I enabled ECN for error. It is disabled again. In cooker we will have ECN compiled in the kernel, but disabled by default in sysctl.conf, each user can configure it if they want. As other people told in the thread, the problem is that the other sites are bad configured, but I suppose that this don't help you :( Sorry for the inconveniences, Juan. -- In theory, practice and theory are the same, but in practice they are different -- Larry McVoy

Check the discussion about it on the kernel mailing list: http://kt.zork.net/kernel-traffic/latest.html#9 In short...there's a routing standard out there that not all routers follow and that 2.4.x has implementedthe sites that are using non-standard compilant routers become unreachable. I'm not 100% sure about this being your problem, but it's a good shot.
