Two Linux books I recommend
by Lanny Marcus 25 May '07

25 May '07

I would like to recommend two (2) Linux books that might be helpful to some of the people reading this mailing list: (1) "Red Hat Fedora and Enterprise Linux Bible", by Christopher Negus. Published by Wiley. Buy the edition for the version of CentOS you are using. This book is very easy to read and is probably best for Beginning to Intermediate users. This is the book I reach for first. (Disclaimer: I wrote a review that was published in one edition of the book and I received free copies of two editions. I have also purchased several editions) (2) "Running Linux", published by O'Reilly. This book is a classic and was recommended to me by an engineer at Red Hat. I have the 4th edition, but there is a later edition available. This book is a tougher read, but, it goes into things more deeply than the other book I recommend. Probably best for Intermediate and Advanced users. I've purchased 2 or 3 editions of this book. There are probably many other excellent Linux books available that others can recommend, especially about specific topics. HTH, Lanny

What does this mean: PCI: BIOS Bug: MCFG area at e0000000 is not E820-resreved PCI: Not using MMCONFIG H/w config: Xeon 2.80GHz 6GB memory AMI BIOS SE7520BD22.86B.P.07.30.0067 WDC 500GB PATA drive (/dev/sde) RocketRaid 182x RAID with 4 500GB drives in non-RAID config (/dev/sda-sdd) This is new with CentOS 5.0 (no problems like this on 4.4 or 4.5). Just curious - it doesn't seem to be dangerous, but I'm just starting up with 5.0 on this machine. -- Mark Hull-Richter DATAllegro (www.datallegro.com) 85 Enterprise, Second Floor, Aliso Viejo, CA 92656 949-680-3082 - Office 949-680-3001 - fax Ask me about CentOS Linux, and escape from Windows forever!

Xen and overall system load
by Fong Vang 25 May '07

25 May '07

In a CentOS 5 dom0, how does one find out the overall system load? In the early days of Xen, I believe an uptime on dom0 provides an overall load for the server. This doesn't seem to be the case anymore.

Found it - permissions on /tmp were 755 (long story). When reset to 777, everything works fine. -- Mark Hull-Richter DATAllegro (www.datallegro.com) 85 Enterprise, Second Floor, Aliso Viejo, CA 92656 949-680-3082 - Office 949-680-3001 - fax

sata_via freeze
by Giampaolo Carmagnani 25 May '07

25 May '07

Hi all, I have a machine with a Assus P5VD2-MX, it has a VIA chipset. The problem is sometimes without any reason all freeze, can't use network and when I type a command in shell occur a I/O error. I already test memory, and the problem are in two similars machines. I see in CentOS foruns someone with the same problem using the sata_via driver but without an answer. I'm running Centos 5, in BIOS disable Jmicron raid, and the sata is in IDE mode. Thanks all.

Re: [CentOS] Re: Centos really slow as VMware Server guest OS
by Brent L. Bates 25 May '07

Oh, I just remembered something else. We were getting a memory error too, either on startup or shutdown, I don't remember which (someone else was actually doing all the work, I just helped a little). After turning off the swap option, the error disappeared.

Re: Centos really slow as VMware Server guest OS
by Brent L. Bates 25 May '07

I thought some people here might like to know what we just found out while trying to get VMWare running under CentOS 5. Before we found the note about changing VMWare from 2 to 1 CPU's, we went to `Edit' -> `Preferences' -> `Memory' and changed the memory option to: Fit All virtual memory into reserved host RAM It had been set to the next option down, second out of 3 (we don't have the system any more to see what it said word for word). This had a HUGE effect on performance. Before the change, it would take several minutes to do anything under VMWare. Startups and shutdowns were dog slow. Turning off the swap options helped a lot. After that, we also changed from 2 to 1 CPU's and that helped a little bit, but the memory option change had the biggest effect. Just thought you might like to know.

Questions about network configuration
by Niki Kovacs 25 May '07

25 May '07

Hi, I'm currently reading chapter 13 of the RHEL Deployment Guide, and taking some notes. I have a few minor questions: /etc/sysconfig/network According to the doc: "This file specifies routing and host information for all network interfaces." Here's how mine looks like: --8<----------------- NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=fujitsu.zuhause GATEWAY=192.168.1.254 --8<----------------- NETWORKING_IPV6= -> I wonder if I can switch that to 'no', since I simple don't use IPV6. Will some apps mysteriously refuse to work when I do this? (You never know...) HOSTNAME=... -> this looks like a redundancy with information provided in /etc/hosts. So what is it for? Can it be left out? GATEWAY=... -> another redundancy, since it's also to be found in /etc/sysconfig/network-scripts/ifcfg-<interface>. Leave it out if it's in the individual interface scripts? More questions to come, but here's a first bunch :o) Cheers, Niki PS: I've started on Linux with Slackware (7.1), hence a habit of configuring my system with Vi rather than some configuration helpers. Even if they do the job as good, it's just a matter of personal taste and habits. -- Dyslexics have more fnu.
