DN@ probs with 2.4 kernel.

[bkurt]

Has anyone else noticed what seems to be a DNS when using the 2.4.0 kernel?? When I run 2.4 and get online I can't load certain webpages and some nslookups fail. But when I reboot back into 2.2.16 kernel it all works fine. Anyone else had this or know what the problems could be. I'm using dialup with slack 7.1. Thanks.

I remeber the same problem i had and few other folks...It's called TCP ECN (explict congestion notification) it's a feature of kernel (under networking options)...It is recommended to have it off for now as some big sites have firewalls that are broken and will refuse connections.Since you have it configured use the /proc to enable/disable it at startup (/proc/sys/net/ipv4/tcp_ecn) with a line in rc.local, echo 0 > /proc/sys/net/ipv4/tcp_ecn will disable it and 1 insted of 0 will enable...hope this helps.

Ok, thanks for the info but I went back and looked at my kernel config and I didn't have the tcp_ecn compiled into the kernel so that wasn't the problem. I did solve the problem thought, but I don't really understand why it works for sure. The problem was a value set for mru and mtu in my /etc/ppp/options which always helped out my connection when I used the 2.2.16 kernel. Once I commented those out and reconnected everything worked fine. So I don't know if it's something with the kernel itself or something with the new version of pppd. ;)
