Intel (brand) Penryn (8xxx) motherboard which works natively with CentOS 4/5?
by Drew Weaver 25 Jan '08

25 Jan '08

Has anyone stumbled across an Intel brand motherboard which both works with the 8000 series of CPUs and with CentOS 4/5 out of the box? (by works I mean the NIC/Disk controllers without "fudgery") The DG31 board "kind of" works but unfortunately it has 2 DIMM slots, the realtek NIC isn't supported (don't know why, its just a standard realtek NIC, although it might be some new PCI-E one). Has anyone found the "Holy Grail" yet? Please let me know :) -Drew

During the bootup I see a message that the memory for crash kernel is not within permissible range. What does it mean, and what should be done about it? Anne

Breaking Windows XP user password?
by Scott Ehrlich 25 Jan '08

25 Jan '08

Granted this is not a UNIX system, but in case there is a UNIX tool to accomplish the goal... I am looking for a bootable CD/DVD (or application to be placed on a CD/DVD to be made bootable) that can let me mount a Windows XP drive/partition (SP1 or SP2), and force-crack the admin password (even if admin account name has been changed, but I know what it has been changed to). The application cannot write to the hard drive - only mount it read-only, read the password file into ram, and show the cracked password. I know I can use the pnordahl utility to try and force-change the password, but I actually want to crack it. The utility should be free. This is a legal request. Thanks for leads. Scott

Re: [CentOS] Random files in homedir gets deleted
by Ross S. W. Walker 25 Jan '08

25 Jan '08

You can enable auditing to determine if the files are disappearing due to human/machine intervention (audit file system deletes) or if it is due to file system corruption (files disappear and no delete audits recorded). It may just be an errant rsync script. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: centos(a)centos.org <centos(a)centos.org> Sent: Thu Jan 03 07:09:11 2008 Subject: [CentOS] Random files in homedir gets deleted On one of my systems I seem to loose a file or two from time to time. Last night, one of my files (/home/online/sh/NattjobbPrivat.sh) was deleted/removed/vanished. Another time it was /home/online/sh/daemon that was deleted. But I can't seem to find anything strange in the logs or in the history, nor would any of my scripts running in crontab mess with those files. Where can I look for clues?

Shearing file systems on the network
by Peter Blajev 25 Jan '08

25 Jan '08

I have 4 systems and each one of them has a partition I'd like to be remotely accessible on the other 3 systems. In other words System1 has Partition1. Systems 2,3,4 should be able to remotely mount Partition1 from System1. Also System2 has Partition2. Then systems 1,3,4 should be able to remotely mount Partition2 from System2 and so on. I tried NFS and it works but only in the ideal world. If one of the systems goes down the whole NFS cross-mounting makes the other systems somewhat unstable. It's a known issue and I believe you guys are aware of it but I just had to see it myself. What would you recommend? What is the best practice for doing that? Unfortunately SAN and NAS are not really an option due to some financial restructions. I'm thinking SMB...? Would that work? Thank you Peter

Why Kudzu, Why?
by Michael Semcheski 25 Jan '08

25 Jan '08

So I have a CentOS 5 machine, which I recently did a 'yum update' on. Everything went fine, but I rebooted as a precaution (just to confront any problems which might arise the first time after an update). And sure enough, when the machine came back up, the network didn't work. Luckilly, someone said (and I quote) 'mv /etc/sysconfig/networking-scripts/ifcfg-eth0.bak /etc/sysconfig/networking-scripts/ifcfg-eth0 and blame kudzu'... So, what did I do wrong, or what should I have done differently? What's the reasoning behind this? I'll bet there is some rationale, and I'd like to understand it. Thanks, Mike

Interesting PXE server setup question
by Rob Lines 24 Jan '08

24 Jan '08

While this is not a problem with CentOS I am hoping to solve the situation using a CentOS machine. For anyone not interested I am sorry to clutter your mail box. For everyone else any ideas or suggestions are welcome. A bit of background: We have an application that runs only in DOS 6.22 at the moment that we would like to run on all of our desktop computers each time they boot up. Our workstations are mostly Windows XP with some Linux. Our goals: We would like to be able to have the machines boot into DOS and run the application and then reboot to the normal hard drive. We would like to have it require no user intervention or as little as possible. We would also like to have it only run the app during the first boot up of the day. Thoughts at the moment: One idea we have at the moment is to create a PXE server with the DOS boot image on it. (I have done that before using Windows RIS but we are trying to avoid a windows Server as RIS is a bit of a pain and it prefers user interaction. It also would not fit well with our solution to have it only run once a day.) We could then run the application and inside the DOS image we could have it reboot the machine. We could then set the client machines to boot PXE as their first boot option. The next thought was to somehow watch the connections to the tftp server where the boot image will be kept and watch for the client IP then have the PXE server create a new firewall rule that would block access from that client to tftp. The thought there is that once the client has downloaded the boot image once it will run it and then on reboot will not be able to find the boot image and, I think, would fail at the pxe boot and move on to the next item in the boot list. Then every midnight the list of blocked IPs would be cleared and we start the process over again. So any suggestions on the best way to take a bootable DOS disk and turn it into an image that a Linux based PXE server can serve, ways to monitor the tftp connections and then add them to the firewall after they have finished downloading the boot image, and any ideas on any better ideas would be appreciated. Thanks for taking the time to read this. Rob

Appreciate the help...
by Scott Ehrlich 24 Jan '08

24 Jan '08

I received some interesting answers to my cron question. Most people said it was not possible. One person reviewed cron's source code and said the source would need to be modified. One person said I should mount the filesystem with noexec. I'll review and test the answers as best I can. To answer several people's curiosities of why I keep pushing - when I'm tasked with a quest, I try to tap all my resources, including this list, to find a solution. One never knows when an answer might be obvious, or perplexing, as this question seems to have been. To some, an answer is obvious. To others, it is perplexing. It all depends on each person's level of knowledge. The more one learns, the more things can become more obvious. Thus, we grow. In the end, like now, I try to provide my findings, and, if valid, may be of benefit to others. I try not to wear out the list, but do what the list was created for - discussion and inquiry of UNIX and related topics. This question proved to test people's knowledge, and I did get some good feedback. Thanks to all, and until the next adventure... Scott
