From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; Q312461; .NET CLR 1.0.3705; .NET CLR 1.1.4322) Description of problem: Formatted my hard drive. Installed fedora core 1. Installed apt and added arjanv's 2.6 apt source to my sources list. Installed 2.6 bin and source. Once booted into 2.6, i'm able to do functions like ping and dig successfully. Samba and NTP are also working. The problem is that I am unable to use programs like mozilla, gaim, lynx. The programs preform the dns lookup successfully, then just sits there while trying to connect. I've tried compileing the network drivers into the kernel, toggleing preempting, and turning off all firewall/filtering options. I've also tried running these programs root and normal user, and have tried 3 diffrent network cards. (2 3com 3c509's and one intel 82557) When i boot back to 2.4, everything works correctly. Version-Release number of selected component (if applicable): kernel 2.6.0-1.107 How reproducible: Always Steps to Reproduce: 1.install fedora core 1 on a dell xps t700r 2.install arjanv's 2.6 kernel 3.try running mozilla/lynx Actual Results: Programs like mozilla/gaim/evolution can't get out to the internet. Expected Results: Programs in question should work the same way as in 2.4 kernel Additional info: Let me know if you need my kernel .configs or any stack trace logs from mozilla.
is it with all websites or only some? my kernel has ECN enabled which is a TCP/IP performance feature but some firewalls on the internet incorrectly block it... (you can turn it off by doing echo 0 > /proc/sys/net/ipv4/tcp_ecn ) If this is the case then the owners of said firewalls need to upgrade the firmware on it; at least on cisco the "broken" firmwares all had security issues that were fixed since.
Bingo! Turning off ECN fixed the problem. I'm using a Netgear fvs318 NAT router with the latest firmware (firmware 2.1, as of oct30th 2003). It wasn't only blocking websites, it was effecting gaim and evolution too. Thank you, your work is greatly appreciated!!!
