parted - is there a problem
by Gregory P. Ennis 25 Sep '07

25 Sep '07

Everyone, I recently added a 300gig Seagate sata drive on a Centos 5.0 and have a couple of questions. The drive was recognized with the device as /dev/sdc. The system came with some SCCI drives that are labeled as /dev/sda and /dev/sdb. I was surprised that the sata drives used sdc. Are the sata drives considered more like SCCI or IDE drives? The real problem occurred when I tried to partition the drive with parted. I used he command mkpart to form one partition of 300 gigs which created /dev/sdc1, and then after 'quiting' parted used mkfs.ext3 to create a file system. Everything went as expected with the ability to mount the file system and copy files into it. However, /dev/sdc1 disappeared when I rebooted. After the reboot /dev/sdc1 was missing and CentOs obviously could not recognize the partition. The error is probably related to my lack of experience with parted so I tried it 2 other times with the same results. I finally gave up and used fdisk which has worked without a problem. By way of observation I could not find a 'write to disk' command in parted like what is present in fdisk. Is there a problem with parted or I am just lacking in knowledge of some of the parted commands. Certainly could not find any write like statements in the man pages or the info pages. Are there others of you that use parted? What did I do wrong? Greg Ennis

CentOS 4.5 system doesn't boot after installing latest updates
by Alfred von Campe 25 Sep '07

25 Sep '07

Today I decided to install all the latest updates (including the -06 kernel). The "yum update" seems to have run just fine (no errors), but when I rebooted the system it just sits there with the word "GRUB" in the upper left hand corner. I booted from the CentOS 4.5 install CD into rescue mode, did a "chroot /mnt/sysimage" and reinstalled grub and the latest kernel, but it still gets stuck in the same place. It's not that I can't boot the new kernel; I can't even get to the grub screen! Any ideas? I am totally stuck at the moment... Alfred

CentOS-5 Hardware Probe
by James B. Byrne 25 Sep '07

25 Sep '07

I installed CentOS-5 on a test machine, a P4 1.8 Ghz Compaq Evo D510 series. This was a clean install onto a new disk drive and everything went well. After updating with YUM and installing Postgresql, Rails for Ruby, Firefox-2 and Thunderbird I shutdown and restarted the system several times without incident. I then pulled the CD-ROM and replaced it with an LG-DVD DVD-RAM/RW device. I also swapped the PS/2 Kb and mouse for USB versions. When I rebooted the system I entered the bios setup and reconfigured for the new device. However, subsequently, Centos bootup has now entered an endless loop. Pluse neither the USB nor the PS/2 kb seem to work after a certain point. On Centos-4 I recall doing exactly the same thing and all that happened was that Kudzu ran during the boot procedure, prompted for the configuration changes and everything went on swimingly. I just verified this behaviour by swapping in a CentOS-4.5 disk on this machine and Kudzu came up, reported on all the config changes, accepted the responses and it booted with the DVD and USB devices installed What is happening in CentOS-5? Is there no hardware probe at startup? Is there some switch that I need to set? I can boot from the CD-ROM on this machine using the LG-DVD but not from the hard drive. Switching back to the original CD-ROM device did not alleviate the problem either so I am at a loss as to what is happening. As I am a digest subscriber the favour of a direct copy of any reply to the list is requested. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

Samba and TCPWrappers
by Bob Chiodini 25 Sep '07

25 Sep '07

Good Morning, I have a Centos 4.5 (x86_64) server running samba to share data with windows users. We've been going through a security audit and the following log entries were noted: [2007/09/24 09:37:29, 0] rpc_server/srv_util.c:get_alias_user_groups(206) get_alias_user_groups: gid of user bendew doesn't exist. Check your /etc/passwd and /etc/group files [2007/09/24 09:37:29, 1] rpc_server/srv_util.c:get_domain_user_groups(298) get_domain_user_groups: primary gid of user [nobody] is not a Domain group ! get_domain_user_groups: You should fix it, NT doesn't like that [2007/09/24 09:37:29, 0] rpc_server/srv_util.c:get_alias_user_groups(206) get_alias_user_groups: gid of user nobody doesn't exist.

Check your /etc/passwd and /etc/group files I am using tcpwrappers and have blocked the subnets that should not access my server. The IP of the auditor is within one of the blocked subnets, but still seems to be getting through. Is samba integrated with tcpwrappers. ldd smbd does not show a reference to libwrap, should it?

/boot partition or not on C5
by mark pryor 25 Sep '07

25 Sep '07

hello, the last 3 times I installed C5, the MBR was unchanged and nothing was written into /boot/grub except splash.xbm.gz there were no stage* files, nor a menu.lst I know how to fix that. Would I have better luck using a partition mounted as /boot? Anyone succeded with Grub that way? I prefer not having to do surgery to get C5 to boot :) -- Mark New Packages for C5 --------- dkms-et131x-1.2.2-el5.noarch.rpm (gigabit ethernet driver) http://www.tlviewer.org/c5repo/web/agere kchm-el5 (CHM client with io-slave) http://www.tlviewer.org/c5repo/kde/ --------------------------------- Luggage?

NFS issue
by Dan 25 Sep '07

25 Sep '07

I am currently running K12LTSP on Centos 5, which is working well but without sound on most machines(ok all). So in order to remedy this and the cd-burning issue I have decided to try to install CentOS locally on one machine and then apply the personalizations via NFS. Steps: I editted the /etc/exports to export the /home dir as per the NFS howto and that seemed to work as the user homes were mounted in the correct place after an edit to my /etc/fstab "192.168.0.254:/home /mnt/home nfs rw,hard,intr 0 0" good :) Then I started adding users, I added one user and did not create a /home/user directory instead pointed the home folder to /mnt/home/user But when I try to login as that user I got the dreaded: "User's $HOME/.dmrc file is being ignored. This prevents the default sessionand languages from being saved. File should be owned by user and have 644 Permissions. User's $HOME directory must be owned by user and not writable by other users." So I looked into the permissions and this is what I see serverside: [root@LTSP ~]# ls -al /home total 64 drwxr-xr-x 8 root root 4096 Sep 15 23:13 . drwxr-xr-x 24 root root 4096 Sep 22 17:45 .. drwx------ 27 ainsley ainsley 4096 Sep 23 19:13 ainsley drwx------ 31 Dan Dan 4096 Sep 24 21:42 Dan drwx------ 27 darren darren 4096 Sep 23 18:17 darren drwx------ 33 devin devin 4096 Sep 24 07:28 devin drwx------ 22 kristi kristi 4096 Sep 24 21:35 kristi drwx------ 21 landen landen 4096 Sep 24 21:14 landen BUT when I look at the /mnt/home listing I see a completely different set of permissions: drwxr-xr-x 8 root root 4096 Sep 15 23:13 . drwxr-xr-x 24 root root 4096 Sep 22 17:45 .. drwx------ 27 devin devin 4096 Sep 23 19:13 ainsley drwx------ 31 Dan Dan 4096 Sep 24 21:42 Dan drwx------ 27 kristi kristi 4096 Sep 23 18:17 darren drwx------ 33 503 503 4096 Sep 24 07:28 devin drwx------ 22 504 504 4096 Sep 24 21:35 kristi drwx------ 21 505 505 4096 Sep 24 21:14 landen the ones in bold are definately wrong, and I have no idea how they are being set. unless it is because they are not accounts on the test machine yet but then neither is the "landen" account and that one has the correct permissions sort of.... the user numbers are correct for the user names by the way. Anyone have any ideas? Thanks! Dan

vmware 1.0.4 lock up on install
by Jerry Geis 25 Sep '07

25 Sep '07

I am not having a good experience with vmware. Twice I have tried it today and it locks up my machine. First attempt was to install centos 4.5 i386. It told me it could not find anything to install on. After a post to the list I was instructed to not do typical, but custom and select LSILogic as the controller. I did and I got past that point. I then goto into an install with 6 minutes remaining on screen and another lock up. Anyone else experiences this with vmware. Is it something I am not doing or its just not going to work for me? I have a stock centos 4.5 X86 AMD X2 as my host and was installing a centos 4.5 i386 guest. Thanks, I was almost there. Jerry
