Motherboards
by Sam Drinkard 05 Oct '05

05 Oct '05

Does anyone have any experience with Super-Micro brand motherboards // dual Xeon cpu's? Had to swap out my Tyan piece of junk and going back with the S-M board. I believe it has similar north/southbridge chips on it -- at least they are the intel MCH ICH5R and PXH plus the 82546GB. One area that the Tyan board was seriously lacking in was in the hardware monitoring department. The S-M board uses a winbond 83627HF chip. Another area I'm wondering about is with the SATA controller. Supposedly the ICH5R supports Raid 0, 1, and JBOD's, but does CentOS handle the sata raid without difficulty? Tnx.. -- Snowman

/proc process information on centos 4.1
by Jerry Geis 04 Oct '05

04 Oct '05

Alex, I did something simple; on one window did more/etc/mail/sendmail.cf on another window did lsof -o -b -p XXX -w where XXX is hte process number and the SIZE column does not change to OFFSET! the size reflects the size of sendmail.cf - I was hoping the "-o" would change the SIZE column to OFFSET column and show at what offset the program has read into the file? AM I doing something wrong? THanks so much.

broadcastclient does not work on CentOS 4.1
by Fong Vang 04 Oct '05

04 Oct '05

This ntp.conf file works fine under RedHat 9: authenticate no #enable auth driftfile /etc/ntp/drift keys /etc/ntp/ntp.keys server 127.127.1.0 fudge 127.127.1.0 stratum 10 trustedkey 1 enable bclient broadcastclient However, it doesn't work on CentOS 4.1. ntpd complains with this error message: Unable to listen for broadcasts, no broadcast interfaces available Has anyone gotten ntp broadcastclient to work under CentOS? This is very similar to the problem explained by this email thread: http://lists.freebsd.org/pipermail/freebsd-questions/2004-August/057010.html Any help is appreciated.

Just need to watch out that the jobs the node is doing at that time are not unacceptably degraded, since we don't have a preemptive scheduler (? I think... haven't been paying atention the last year or so.) yet. Using a blockisize that takes advantage of cache sizes (several levels of these) would be optimal, but the 80/20 rule seems to apply here. So I always just use a block size that is a cylinder (not really a cyl, but who knows what they really are these days?) based on the HD parameters. What's really important is not the size, but the reduction in number of system calls. Anyway, not a major issue, but since I luv dd (and ed and other old time real *IX stuff) I didn't want it to get a bad rap! ;) > -- Les Mikesell lesmikesell(a)gmail.com > Bill

I don't know what was on the web page, but when things don't behave as expected, it's always worth looking at a man or info page. In this case, you would see that you did not use the "-p PASSWORD" param correctly. Why? A qualifying phrase often overlooked, "... as returned by crypt(3)". Exactly how they intended to make this administrator-friendly is not apparent to me. I've not easily found a CLI that will return an encrypted version of a proposed password, allowing something like passwd -p `encryptit password` ... 'Course, my forte is not administration, so I may be just ignorant (at least, I hope that's all it is :)) ). Most folks just byte the bullet, even in scripts, and type it in at the console. Or grab an encrypted starter passwd (possibly copied from /etc/passwd or /etc/shadow (more likely) ?) and use that and specify that passwd must be changed upon initial login. ><snip> Bill

LVM & Knoppix
by Robert 04 Oct '05

04 Oct '05

I'm probably missing something very simple. My hard drive looks like this: [root@mavis ~]# fdisk -l Disk /dev/hdb: 163.9 GB, 163928604672 bytes 255 heads, 63 sectors/track, 19929 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hdb1 * 1 13 104391 83 Linux /dev/hdb2 14 19929 159975270 8e Linux LVM Inside the Logical Volume there are my / partition and swap partition and CentOS4 sorts it out just fine. [root@mavis ~]# mount /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) <snip> /dev/hdb1 on /boot type ext3 (rw) However, if I boot e.g. KNOPPIX, I'm unable to mount anything except the /boot partition on hdb1. Is there any way out of this intolerable situation other than doing a full backup, repartitioning the hard drive without that damnable LVM and restoring the whole thing from the backup?

/proc process information on centos 4.1
by Jerry Geis 04 Oct '05

04 Oct '05

Is there a way to tell through /proc or something else which files a process has open and more importantly what position the read pointer is in for that open file? As an example if I am reading a file with a program I have no control over, and I kill that program, I need to know when in the data file that program was reading at that time. Is this information available and if so how to read it? Thanks, Jerry
