Would you mind trying the fedora-netdev kernels in order to ensure that this problem is still pending upstream? http://people.redhat.com/linville/kernels/fedora-netdev/ Please give them a try and post the results here...thanks! I tried but got no update... $ sudo yum update Loading "installonlyn" plugin Setting up Update Process Setting up repositories core [1/4] fedora-netdev [2/4] updates [3/4] extras [4/4] Reading repository metadata in from local files No Packages marked for Update/Obsoletion I have also run into this problem but only with one site: http://www.csfm.com To reproduce, do wget http://www.csfm.com: wget http://www.csfm.com --08:48:52-- http://www.csfm.com/ => `index.html.1' Resolving www.csfm.com... 216.187.71.116 Connecting to www.csfm.com|216.187.71.116|:80... connected. HTTP request sent, awaiting response... I have tried different versions of the 2.6.17 kernel on fc4 (i386) and fc5 (x86-64) and all exhibit this problem. I have also tried 2.6.16 and 2.6.15 kernels on fc4 and 2.6.9 kernels on fc3 and RHEL and all work. I have noticed the same problem with a few of our servers. 2.6.16 kernels work fine, 2.6.17-1.2157_FC5 just hangs when connecting using various protocols (have had it fail when connecting with http, ftp, pop and smtp). Network card being used in this case is an Intel Pro100 (e100 driver). Re: comment 2 -- please try the update again, as I have published later FC5.netdev kernels...thanks! I tried again - and got a new kernel uname -a Linux saturn 2.6.17-1.2157.2.1_FC5.netdev.7 #1 Fri Jul 28 17:30:46 EDT 2006 i686 i686 i386 GNU/Linux However, the problem is still there - web pages hang. dmesg b44.c:v1.01 (Jun 16, 2006) eth0: Broadcom 4400 10/100BaseT Ethernet 00:02:e3:53:5d:b2 b44: eth0: Link is up at 100 Mbps, full duplex. b44: eth0: Flow control is off for TX and off for RX. Can you attach the output of runnint 'sysreport' on the box in question? Thanks! The problem that I had has been resolved. To reiterate, after upgrading from 2.6.16-1.2133_FC5 to 2.6.17-1.2157_FC5 most web sites did not respond to web page requests using a web browser. One of our sys admins looked into the matter. He tells me that based on this article http://www.mail-archive.com/pf%40benzedrine.cx/msg07837.html he changed the configuration of the firewall (which runs BSD) that I'm behind to ensure that the pass rules match these criterions 1) all 'pass' rules that can match TCP have 'flags S/SA' 2) all 'pass' rules have 'keep state' After that the problem vanished. Looks to me like the latest kernel changed something for which the firewall configuration had to be changed (or maybe should have been changed to a long time ago). If you still want the 'sysreport' I will attach it. Or should I close this report? Claus, sysreport will not be necessary...thanks! |
