To the Linux Community at Large: I reported to this list back in January, 2010 that the standard x86_64 kernel, when built from the src.rpm and modified for AMD K8 / K10 Extensions would not build. I reported this here and to Red Hat via Bugzilla ID number 558367. RH AS / Centos 5.3 worked fine. That was Centos 5.4 / Red Hat Enterprise AS 5 Update 4. Today we tried to optimize Red Hat Enterprise AS 5 Update 5. Same problem. At last check all kernels from 2.6.18-10 to 2.6.18-194 won't build with AMD specific optimizations. For 9 years now we have used and supported Centos and before that white box. We have sold, installed and provided consulting on Red Hat Linux and RH Enterprise Linux, Centos, Scientific Linux, OpenSUSE and SUSE Linux Enterprise. In April this year, the bug was still marked as new and we had to recommend to a customer to use SUSE Linux Enterprise instead of Red Hat Enterprise, as Novell's product supports optimizations in its kernel for AMD Opterons. 12 SLES Enterprise copies were sold to the customer. I'm sure that would have easily paid for the fix required in Redhat's kernel. I am beginning to wonder if Red Hat is getting too big? Or that it just does not care. Other ideas less pleasant come to mind Today, the old bug was still marked as new (6+ months and counting). I entered a new bug report for RH 5.5 for the same issue. Is there no way, unless you are a huge customer, to get your bug listed as anything except LOW PRIORITY?? Now we are looking at the AMD G34 CPU's and are building some demo units. I think its time to benchmark these systems with the working - non optimized Red Hat / Centos Linux versus the optimized Opensuse / SLES Linux for standard server functions and publish them. Has anyone else had this NON response from Red Hat for similar issues? I'd like to hear from them.

[CentOS] EC2 elastic IP failover
Hello, I have two EC2 instances and I would like to setup some sort of failover strategy for them. They currently act as load balancers, forwarding layer 7 traffic using haproxy and stunnel to other EC2 instances. One of these load balancers currently has an elastic IP assigned with an A record pointing to it. What I'm trying to achieve is to remap this elastic IP in the eventuality of an instance failure. I know that heartbeat/keepalived/pacemaker/openais can do this without any kind of trouble but these tools don't work in Amazon's cloud due to restrictions imposed on their network (multicast/unicast traffic). One way of doing this would would require a network monitoring system that supports event-based script execution. At this point I'm thinking about writing a wrapper script around 'ec2-associate-address' and upon detecting a failure on instance A, my network monitoring system would simply execute the script on instance B in order to re-associate the elastic IP. Does anyone have a better/more elegant solution to this? Regards, -- Andrei ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

It has been stated many times and on many fora that Red Hat's bugzilla is not a mechanism for support. They are under no obligation to address issues raised there. Is it nice when they do? Absolutely. Should you expect (nay, demand) it? Nope. The proper way to get Red Hat to address an issue is to open a ticket via your support contract with them. Now we are looking at the AMD G34 CPU's and are building some demo units. I think its time to benchmark these systems with the working - non optimized Red Hat / Centos Linux versus the optimized Opensuse / SLES Linux for standard server functions and publish them. While that may be interesting to compare distributions, I think it would do little to evaluate the benefit of the kernel CPU optimizations. There are just too many other variables. I would be very interested to see numbers comparing the exact same Red Hat distribution benchmarked with and without the kernel optimizations (you said 5.3 worked just fine). Do you have previous numbers on that showing a marked benefit? -- Joshua Baker-LePain QB3 Shared Cluster Sysadmin UCSF ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] DNS problem while trying to join windows 7 to samba3x pdc
After a little bit of research I feel a little vindicated. It seems that Samba3x seporated out nmb. On Samba 3.0 the nmb service does not show up in the chkconfig. It simply starts and stops with smb. On Samba3x it seporates out nmb and it does not start by itself. So based on my experience I never needed to start nmb seporately so just like all of you it didn't enter my mind as the culperate. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I thought the name calling was rather rude/harsh and uncalled for and think you did a pretty good job of tracking down the problem. Generally though, in your setup I would probably discourage cross subnet browse lists because they can get large and slow and generate excessive traffic. I would probably segregate student computers and teacher computers and not display teacher computers to students, etc. Craig -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] OpenOffice.org 3.1 installation was corrupted-installed again, nothing in Applications/Office menu
I had a corrupted installation of OpenOffice.org 3.1. When I used yum remove openoffice.org-core the response was package openoffice.org-core available but not installed, but then, when I used yum install openoffice.org-core there was a long list of Transaction Check Errors. I then removed openoffice.org3.1-redhat-menus-noarch which was in the errors. Here's the first of those errors: Transaction Check Error: file /usr/bin/soffice from install of openoffice.org-core-3.1.1-19.5.el5_5.1.i386 conflicts with file from package openoffice.org3.1-redhat-menus-3.1-9393.noarch The transaction completed OK, after I removed openoffice.org3.1-redhat-menus-noarch, but now, there is nothing in Applications/Office menu for OpenOffice.org :-) Question: How do I get the different entries for OpenOffice.org to appear in that menu again so I can launch the application?
