upgrade issue
by Paul A 13 Apr '12

13 Apr '12

I have an old dell 2450 that was running kernel 2.6.18-308.1.1.el5 I then upgraded it via yum to 2.6.18-308.1.1.el5. Now when the server boots to the new kernel, 2.6.18-308.1.1.el5 it hangs on "starting iSCSI" and the weird thing is when I tried to switch back to the older 2.6.18-308.1.1.el5 kernel it works fine but the network script fails to start. I'm not really sure what I should do, if someone can give me an idea on what I need to do to fix the iSCSId issue on the new kernel or revert back to the old kernel and fix the network issue. The odd thing is both kernel load the e100 network driver but on the older kernel I can get the network script to start. I would appreciate some help. paul

Intel Graphics on Dell Optiplex (Generic Question)
by Brian McGrew 13 Apr '12

13 Apr '12

Good morning, Dell has once again obsoleted out hardware and we're moving forward to the Optiplex 790 as a shipping platform with the integrated Intel graphics chip. We're using CentOS 5.6 32 and 64-bit with a 2.6.18 kernel. What are my options for supporting the newest Intel graphics chipsets? -b

Re: [CentOS] FOUND_THE_ISSUE -- URGENT -- pseudo network interface creating problem with dhcp-- centos 5.5

Hi John, Thanks for the explanation. I looked at the BIOS and found the following where the pseudo MAC address is from: ################################################################################ Planar Ether 1 MAC Address: E4:1F:13:77:16:5F ============> This is shown in ifconfig eth0 Planar Ether 2 MAC Address: E4:1F:13:77:16:60 ============> This is shown in ifconfig eth1 BMC MAC Address: E4:1F:13:77:16:61 ======> This is the MAC address my SW is showing on the SW port connected to my eth0 Slot 1 MAC Address: 00:15:17:EB:AE:A4 ===========> This is shown in ifconfig eth2 ######################################################## I got some pointers over web on how to disable the BMC so that it would not use eth0. But another question in my mind is what is the significance of BMC MAC address here? (How different is it from the MAC addresses of other conneted NIC cards and how OS uses it)? And why not BIOS shows all the NIC devices detected ? (because "ifconfig -a" shows eth0/eth1/eth2/eth3 for me with eth3 MAC is: 00:15:17:EB:AE:A5. I could not see eth3 MAC address in the above BIOS output). Thanks for your time.

CentOS 6.2 anaconda bug?
by Lars Hecking 13 Apr '12

13 Apr '12

I have a kickstart file with the following partitioning directives: part /boot --fstype ext3 --onpart=sda1 part pv.100000 --onpart=sda2 --noformat volgroup vol0 pv.100000 --noformat logvol / --vgname=vol0 --name=lvol1 --useexisting --fstype=ext4 logvol /tmp --vgname=vol0 --name=lvol2 --useexisting --fstype=ext4 logvol swap --vgname=vol0 --name=lvol3 --useexisting logvol /data --vgname=vol0 --name=lvol4 --noformat The purpose is reinstalling a machine with a given partitioning scheme and preserve files on /data across the reinstall. Kickstarting a machine with these instructions, it comes up without the /data partition, it is not mounted and not in fstab. But the lvol exists and can be mounted manually, with all data preserved. /root/anaconda-ks.cfg shows the following: #part /boot --fstype=ext3 --onpart=sda1 #part pv.008002 --onpart=sda2 --noformat #volgroup vol0 --pesize=32768 --useexisting --noformat pv.008002 #logvol / --fstype=ext4 --name=lvol1 --vgname=vol0 --useexisting #logvol /tmp --fstype=ext4 --name=lvol2 --vgname=vol0 --useexisting #logvol swap --name=lvol3 --vgname=vol0 --useexisting #logvol --name=lvol4 --vgname=vol0 --useexisting --noformat I.e. the mount point was dropped. Any ideas why this might be happening? I couldn't find anything related in the migration guide, and this looks like a bug to me.

compiling openssh5.8src.rpm looking for Xlib.h
by Vinay Nagrik 13 Apr '12

13 Apr '12

Hello Group, I created a VM with 5.7 Centos DVD-1. My task is to compile openssh5.8p2 (src.rpm downloaded from openssh site.) on the system. It gave some errors about some buildrequires rpm not found. I took care of them. Now it is complaining about > [root@akjain-centos5 SPECS]# rpmbuild -bb openssh.spec > error: Failed build dependencies: > /usr/include/X11/Xlib.h is needed by openssh-5.8p2-1.x86_64 > I have copied Xlib.h from another machine (running el5) into /usr/include/X11 directory. But it still does not recognize this particular file "Xlib.h" and continues to give same error. Do I need a particulare Xlib.h for this machine, 'if yes', then can someone tell me where from to get this file. I will appreciate this. Thanks in advance. nagrik

Interpretation of a hardware error
by m.roth＠5-cent.us 13 Apr '12

Hey, folks, I've just started seeing Apr 12 13:09:59 <server> kernel: [Hardware Error]: MC4_STATUS[Over|CE|MiscV|-|AddrV|-|Poison|CECC]: 0xdd0accf2001d011b Apr 12 13:09:59 <server> kernel: [Hardware Error]: Northbridge Error (node 1, core 1): ECC error in L3 cache tag. Apr 12 13:09:59 <server> kernel: [Hardware Error]: cache level: L3/GEN, tx: GEN, mem-tx: RD Apr 12 13:09:59 <server> kernel: [Hardware Error]: Machine check events logged I'm guessing, unhappily, that this means the on-chip cache, not DIMM. Does anyone here know? mark, who'll be the one to call it in under warranty....

Dear All Greetings, i am admin for ISP two years now, relay emails for more than 300 companies (CentOS/Postfix). Relaying more than 10,000 messages every hours successfully. no one has ever compliant for non delivery. but i cannot relay to this domain. The servers responsible for accepting messages are rejecting. i have given the whole log for experts to monitor. it is something out of control, because it is not my problem. Our server has all record created (A,MX,PTR,SPF etc). i have three relay hosts fully functional. destination server is not accepting from any relay host. can anyone try from his server and see if it is deliverable to ray(a)tata-nigeria.com Thanks / Regards Prabhpal S.

Installing CentOS 6.2 *TO* a USB drive, not installing from USB.
by Emmanuel Noobadmin 13 Apr '12

13 Apr '12

I'm trying to setup a very small system intended for doing monitoring/logging. It's done on an Intel Atoms in a small box and the idea was to simply run it off a pair of USB flash drives in software RAID 1. Now the problem is that while the 6.2 DVD installer could go through the entire install process, grub will load then just stop at the prompt. The system will work if I use a SATA hard disk so motherboard compatibility is not an issue. Attempting the various methods to re-install grub (via rescue mode) or using the grub prompt to setup the disk does not work either. grub just does not seem to be able to find the USB drives. e.g. commands like root (hd0,0) just says device not found. This is despite grub having just loaded from it and despite that grub-install in rescue mode does not report any error. Same problem even if I just go with one USB drive in a plain vanilla ext3 setup. It seems that some sites are saying that EL variants just don't seem to be adaptable to installing and running off USB drives. Is this really the case and that I should be looking at using another distribution or am I just missing some crucial steps in the process?

Nvidia security vulnerability (CVE-2012-0946)
by Phil Schaffner 12 Apr '12

12 Apr '12

Not strictly a CentOS issue, but users of the Nvidia drivers should be aware of this. See their announcement[1] for details. Users of the the manufacturer's driver, or the ELRepo kmod-nvidia driver[2] should update ASAP to the new version.
