Red Hat Bugzilla – Bug 207267
suffering delays and timeouts accessing web pages over firefox (seems to be no firefox bug though)
Last modified: 2008-05-06 12:22:29 EDT
Description of problem: If I try to access some web pages like www.swox.org/gmp the response i bad. Sometimes it just takes some minutes, sometimes it even results in a timeout. The owner of the site (Torbjorn Granlund) mentioned that this is most likely a bug in the linux kernel and can be worked around using the following command: echo 0 >/proc/sys/net/ipv4/tcp_window_scaling indeed this fixes the problem, but is there already an offical patch? Version-Release number of selected component (if applicable): Linux prime.mydomain 2.6.17-1.2187_FC5 #1 SMP Mon Sep 11 01:16:59 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux How reproducible: in about 90% of all cases Steps to Reproduce: 1. open firefox 2. enter the url (see above) 3. wait 4. wait longer :o) Actual results: timeouts. I haven't recognized somethink like that on other web sites yet, but it seems strange to me, that I can do a workaround on my machine to solve this problem. Is it really a problem on my machine? Expected results: the page is displayed after the usual Additional info:
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.
This bug has been mass-closed along with all other bugs that have been in NEEDINFO state for several months.

If you are not the reporter, you can add a comment requesting it be reopened, and someone will get to it asap. Thank you.
This appears to be a kernel bug and not a problem with the browser. I have found two web pages that I cannot access: www.nohrsc.noaa.gov and www.gpsworld.com, and found the same behavior on two different FC6 computers. If I boot with a non-Fedora live CD, I can access these web sites. If I set up an ssh tunnel, I can access these web sites. I have run tests with iptables and selinux disabled, and the problem remained. The simplest test is to run: wget -d www.nohrsc.noaa.gov It consistently opens the socket, sends the http request, and then hangs: "awaiting response..." Note the h/w I have is i386, and I'm running fc6.
It really is not a kernel bug. It is a bug with the routers between you and the site that are visiting. To be specific it is firmware not adhering to the RFCs. Just curious, what are the "non-Fedora" CDs that work with this? I would expect that all of the new distros would have this problem since this functionality was taken from upstream.
The live CD is Ubuntu 6.06.1, kernel is 2.6.15-26.
