Old thread:how many people still use NIS?
by Nico Kadel-Garcia 21 Nov '10

21 Nov '10

Good morning! I've been offlist for years, and hopping back on for various reasons, I see a thread that I'd like to add to. There's an old thread on NIS use in Centrify that I'd like to add some comments to. I'm still forced to work with NIS for various reasons, including interaction with heavy duty NAS's that require it for NFSv4. I have been busy falling in serious love with Centrify (www.centrify.com) for this. For an environment that already has an extensive Active Directory investment, it's a way to save weeks or months of expensive engineering time and get on with your job. It's a commercial toolkit, reasonably open source friendly and with free components for home users. It provides a very good plug-and-play solution to merging Linux and UNIX authentication, including NIS support, to an Active Directory back end. They basically do what I'd do if I had the time, including workable GUI's and error reporting. You get genuine single-sign-on, commercially supported Putty for your Windows clients, Kerberos password handling, commercially supported OpenSSH 5.x with GSSAPI, good support for multiple "zones" that have different sets of authorized users, scriptable toolkits for adding or adding machines to the relevant zones, etc., etc. It works well with CentOS 5.x, and saves me the work of having to manually compile my own OpenSSH to get GSSAPI support. And the NIS plugin works *very* well and saves weeks of work building your own solution with the limited and out of date components in CentOS or RHEL 5. It "Just Works(tm)".

PATA Hard Drive woes
by Keith Roberts 21 Nov '10

21 Nov '10

Hi All. Yesterday I was installing Centos 5.5 to my web server, and it looks like the main hard drive has gone AWOL. Fedora 12 put the file system into r/o mode. The drive is an Hitachi, still under warranty. There are bad sectors on it, and running the Hitachi DFT tool confirms this. Also I cannot repair the bad sectors. Would this be caused by a faulty I/O chip, or is it safe to say it's definately the HDD at fault? Kind Regards, Keith Roberts -- In theory, theory and practice are the same; in practice they are not. This email was sent from my laptop with Centos 5.5

Old metadata for centosplus 4 repo.
by I.Piasecki 20 Nov '10

20 Nov '10

Hi Centos maintainers ! Could You please refresh repo data for centosplus reposytory 4 ? There are new kernels rpms, but repo index files arn't updated. Please fix that. For example: http://mirror.centos.org/centos/4/centosplus/x86_64/ rpm from 20 oct 2010 but meatadata from 28 sep 2010 ... P.S: That was 17 nov 2010 fixed for centosplus 5 repo, but centosplus 4 was omitted. Best regards, -- Ireneusz Piasecki

centos 5.5--gnome desktop--all icons disappeared.
by fred smith 20 Nov '10

20 Nov '10

gang, I feel dumb having to ask this... I've got a Centos 5.5 installation (it's not new, I've been using it for over a year on this machine) and all of a sudden just a few minutes ago everything on the gnome desktop disappeared. no icons, right-click doesn't bring up a context menu. the panels are still there, though, thank goodness. tried logging off and back on but that didn't help. I'm perusing the centos forums for clues, and thought I should ask all of you too in parallel. Suggestions appreciated, thanks in advance!

kickstart raid disk partitioning
by Roberto Nunnari 20 Nov '10

20 Nov '10

Hello. A couple of years ago I installed two file-servers using kickstart. The server has two 1TB sata disks with two software raid1 partitions as follows: # cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sdb4[1] sda4[0] 933448704 blocks [2/2] [UU] md0 : active raid1 sdb1[1] sda2[2](F) 40957568 blocks [2/1] [_U] Now the drives are starting to be failing and next week I'll backup /homes, reinstall OS with kickstart, and finally restore /homes. There's a problem with how the kickstart process partitions the disks, though. As you may have noticed above, md0 is made up of sdb1 and sda2. Could anybody help me understand how to make the partitions on the two drives identical still using kickstart? Here's the relevant part from the kickstart file: zerombr yes clearpart --all --initlabel bootloader --location=mbr part /boot --fstype ext3 --size 250 --asprimary --ondisk sda part swap --size 2048 --asprimary --ondisk sda part raid.01 --size 40000 --asprimary --ondisk sda part raid.03 --size 1 --grow --asprimary --ondisk sda part /boot2 --fstype ext3 --size 250 --asprimary --ondisk sdb part swap --size 2048 --asprimary --ondisk sdb part raid.02 --size 40000 --asprimary --ondisk sdb part raid.04 --size 1 --grow --asprimary --ondisk sdb raid / --level=1 --device=md0 --fstype ext3 raid.01 raid.02 raid /home --level=1 --device=md1 --fstype ext3 raid.03 raid.04 ..but here's the produced partitioning on the two drives: # parted /dev/sda print Disk geometry for /dev/sda: 0.000-953869.710 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 251.015 primary ext3 boot 2 251.016 40248.786 primary ext3 raid 3 40248.787 42296.132 primary linux-swap 4 42296.133 953867.219 primary ext3 raid # parted /dev/sdb print Disk geometry for /dev/sdb: 0.000-953869.710 megabytes Disk label type: msdos Minor Start End Type Filesystem Flags 1 0.031 39997.771 primary ext3 boot, raid 2 39997.771 42045.117 primary linux-swap 3 42045.117 42296.132 primary ext3 4 42296.133 953867.219 primary ext3 raid I'm not asking because I'm picky, but just because, it would have made my life easier to fix bad blocks on disks by dd from good block on disk1 to bad block on disk2, and as next week I'll reinstall, I'd prefer to do it the right way. Some more bits about my environment: # cat /etc/redhat-release CentOS release 4.8 (Final) # uname -rms Linux 2.6.9-89.0.18.ELsmp i686 Thank you and best regards. Robi

juniper netscreen (ssg5) and centos
by aurfalien＠gmail.com 20 Nov '10

20 Nov '10

Hi all, Lookin to do an IPSEC VPN between a Juniper SSG5 and Centos 5.5. Reading some docs that ref /etc/ipsec-tools.conf but they do not exist on my box being Centos 5.5. The package ipsec-tools is installed and I'm guessing /etc/racoon/ racoon.conf is what I am looking for. Anyways, some help would be very appreciated. - aurf

Hallo, yesterday from 3 to 11 pm UTC our Java application was down. As far as I know, the server java.sun.com was not available. Needs any java application direct access to sun? Can I stop this hell? Any idea? Best regards Helmut

Centos podcast on FLOSS weekly
by Les Mikesell 19 Nov '10

19 Nov '10

If you've ever wondered what Karanbir Singh looks like, check out this week's (142) video podcast at http://twit.tv/floss. I'm only partway through the audio version (will finish on the drive home) and haven't heard anything that would be surprising to people already using Centos yet but it's a great presentation and something to recommend to people who aren't familiar with the project. -- Les Mikesell lesmikesell(a)gmail.com
