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.

FSCK on mounted filesystem (LVM/DRBD)?
by Rafał Radecki 12 Apr '12

12 Apr '12

Hi All. I have two running servers (drbd primary, drbd secondary). When there is a problem with one of them we switch to the second one. Currently on the /dev/drbd0 (it has /xxx ext3 filesystem directly on it) we have some filesystem problems (after fsck -n). I would like to correct these errors but the filesystem should be unmounted first (I would like to avoid it if possible). Is there a way to make fsck -a on mounted filesystem for ext3? My setup is: ext3 filesystem (problems) ^ DRBD ^ LVS ^ RAID Any ideas? Best regards, Rafal.

centos 6.2 md0 boot - no boot actually
by aurfalien 12 Apr '12

12 Apr '12

Hi all, Taken from this link; https://www.centos.org/modules/newbb/print.php?form=1&topic_id=34988&forum=… Seems like I am having the same issue. I assigned my boot loader to be on /dev/md0 rather then the default of /dev/sda1 Does any one have insight to this? Thanks in advance. BTW, I have no swap partition and will do a swap file instead, easier to manage. Do I need swap to boot? - aurf
