Memory vs. Display Card
by Rick 28 Oct '25

28 Oct '25

Since memory has become quite cheap lately I decided to move from 2 GB to 6. When I installed the memory every thing was fine until I went to run level 5. At that point the screen turned to garbage and the system froze. Is there a way to fix this so I can use the memory I bought? Do I need a new display card?

SSD for Centos SWAP /tmp & /var/ partition
by Keith Roberts 03 Sep '25

03 Sep '25

Has anyone actually used a SSD in a Centos setup? My little experiment with a s/h WD drive for /tmp and SWAP partitions kicked the bucket on Wednesday, when the poor WD drive caught the click-of-death. It was a s/h drive to start with and lasted about 4 months. But that was without the /var/log/ partition being written to it, as I mounted that back onto /var/log from the original drive. So I had to install another (WD) drive, and repartion it and rebuild my RPM package database, from the backed-up Packages file. That seems to be all OK now. I'm wondering if it would be a good idea to use a new SSD for moving all the disk i/o to, that Linux likes to do so often. Plus putting SWAP onto a decent SSD should speed things up somewhat. Here's a short video of a laptop fitted with a SSD drive booting macOS, compared to a similar laptop booting from the standard HDD. The laptop with the SSD boots and loads some apps in 28 seconds. The other one takes twice as long. http://eshop.macsales.com/shop/SSD/OWC/Mercury_Extreme_Pro_6G/?utm_source=t… Kind Regards, Keith Roberts ----------------------------------------------------------------- Websites: http://www.karsites.net http://www.php-debuggers.net http://www.raised-from-the-dead.org.uk All email addresses are challenge-response protected with TMDA [http://tmda.net] -----------------------------------------------------------------

Re: [CentOS] sieveshell fails to start on CentOS 6.0

Try specifying both --user and --authname as appropriate. sieveshell can be misleading in its error messages, and you may actually have an authentication error rather than a connection error there. You could run it under strace to make sure. Devin

IE 9 not sending digest auth info
by Paul Heinlein 10 Jan '13

10 Jan '13

I migrated our internal wiki server last week, and some IE users aren't able to authenticate. The service is hosted by Apache using Digest authentication. It migrated from Apache 2.2.9 (Debian 5) to Apache 2.2.15 (CentOS 6). The internal hostname for the wiki server is a DNS CNAME that was repointed from one host to another during the cutover. In a normal session, 1. Client sends GET 2. Server sends 401 with WWW-Authenticate header 3. Client sends GET with Authorization header 4. Server sends 200 with Authentication-Info header and page content When using IE 9 (and possibly 8, I'm still trying to track that down), 1. Client sends GET 2. Server sends 401 with WWW-Authenticate header 3. Client resends GET (*without* Authorization header) 4. Server sends 401 with WWW-Authenticate header 5. Etc. IE seems to be ignoring 401 and/or the WWW-Authenticate headers. Using Chrome on Windows works fine; the issues are specific to IE. Any ideas? My google-fu has failed me. -- Paul Heinlein <> heinlein(a)madboa.com <> http://www.madboa.com/

CentOS4 desktop has stopped recognizing removable media - haldaemon problem?
by Bart Schaefer 18 Feb '12

18 Feb '12

USB sticks and cameras used to pop right up on my desktop. Now they don't. I've checked the Gnome "Drives and Media Preferences" and nothing has changed -- I have "Mount removable media when inserted" etc. (Tried toggling it off and back on, no effect.) I've logged out and back in, even rebooted. /var/log/messages shows the devices are being recognized by udev: Jun 27 19:53:37 torch kernel: Attached scsi removable disk sde at scsi11, channel 0, id 0, lun 0 Jun 27 19:53:37 torch scsi.agent[13576]: disk at /devices/pci0000:00/0000:00:0b.1/usb1/1-5/1-5:1.0/host11/target11:0:0/11:0:0:0 Jun 27 19:53:37 torch udevd[1347]: udev done!

Rebasing to 699 I restarted hald (service haldaemon restart) and it picked up one of the two devices I'd plugged in, but not the other.

Folks The system involved is a 32-bit system, installed via the net about a week ago. The command yum update encountered the following diagonstic Error: Package: yaf-1.3.2-1.el6.rf.x86_64 (@rpmforge) Requires: libfixbuf-0.9.0.so.8()(64bit) Removing: libfixbuf-0.9.0-1.el6.rf.x86_64 (@rpmforge) libfixbuf-0.9.0.so.8()(64bit) Updated By: libfixbuf-1.0.1-1.el6.rf.x86_64 (rpmforge) Not found You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest The repositories I use are: base epel extras rpmforge updates virtualbox I wonder if using priorities would help? Rpmforge is "supposed" to be non-conflicting, but then.... Please let me know what I should do. David

[C6] Some typical apps missing?
by Marko Vojinovic 08 Oct '11

08 Oct '11

Hi everyone! :-) I just installed CentOS 6 on one of my desktop machines, and yum now tells me that some of my favorite apps are not present in any of the repositories I configured. To name a few: ktorrent, kile, krusader, pavucontrol, mplayerplug-in (or is it now gecko-mediaplayer), xine, xmms, and so on... All these apps were readily available for C5, and I used them happily. I am mostly surprised with the absence of *any* torrent client, bar the rtorrent (which doesn't have a man page and I have no idea how to use it). Also kile, krusader and pavucontrol are quite basic and common apps... The configured repositories are: base, updates, extras, rpmforge, elrepo, as reported by yum. What am I missing? I would also be grateful if anyone has a suggestion for a reasonable (and available) substitute for any of these apps. I usually prefer KDE4 apps, but will use anything that works. I found some (rtorrent, mozilla-vlc, gnome-volume-control), but I am not exactly thrilled with their quality, so I'm hoping someone has a better suggestion. Google didn't want to be my friend this time, all hits were related to C5... ;-) TIA, :-) Marko

VLAN support?
by Les Mikesell 03 Oct '11

Not receiving root mail
by Anne Wilson 26 Sep '11

26 Sep '11

Although I have the alias defined in /etc/aliases and /etc/postfix/aliases, I'm not receiving root mail. Following the previous thread about unreceived logwatch mail, I tested with a manual run of logwatch, and found that my ISP is rejecting the mail because it is seeing an envelope carrying my local address. My suspicion is that the mail is going out via sendmail instead of postfix-sendmail. IIRC there used to be system-switch-mail or a similarly named package. I can't find any such package - and can't remember which file it edited. Can someone please point me to that file? Anne -- New to KDE Software? - get help from http://userbase.kde.org

Where are the CentOS 6 security updates?
by Lintula 09 Sep '11

09 Sep '11

The release announcement for CentOS-6.0 posted on CentOS-announce on Sun Jul 10 mentioned that: > Since upstream has a 6.1 version already released, we will be using a > Continous Release repository for 6.0 to bring all 6.1 and post 6.1 > security updates to all 6.0 users, till such time as CentOS-6.1 is > released itself. There will be more details about this posted within the > next 48 hours. I have not noticed anything said about this since, and I can't find any security updates. Firefox, for instance, is at 3.6.9. This is about a year old with many known security problems, so it really shouldn't be used. CentOS 5 and RHEL 6 have 3.6.18. Are there still no security updates available for CentOS 6, or have I just managed to completely miss how to access them?

by sylvan.dcunha＠gmail.com 08 Sep '11

dear All, I had a Centos 5.5 OS running for about 6 months used as a Xen VM server prfectly running 3 Virtual machines Its a Sun Blade server with 8 core Xeon Proceesor with 32 GB Ram couple of days back I added another 32 gb ram . The bios shows the added ram that is now it shows me 64 GB but the Centos OS just recognizes 32gb only the OS details are: Centos release 5.5 final Kernel 2.6.18-194.32.1.el5xen on an x86_64 now also running uname -a shows me Linux hypervisor2 2.6.18-194.32.1.el5xen #1 SMP Wed Jan 5 18:44:24 EST 2011 x86_64 x86_64 x86_64 GNU/Linux shows that PAE support is not there I do believe that installing kernel PAE with yum should solve the problem but since the server is a online production server just wanted to verify if I would run into some problems apprecite your kinf help and suggestions regards sylvan

managing a rack full of centos servers
by John R Pierce 05 Sep '11

05 Sep '11

to date, I've done all my administration on a manual 1 at a time basis, as each system has been pretty much unique. its looking like I might need to setup a deployment of a dozen or 2 basically identical machines, all running pretty much the same sorts of stuff. I have zero experience with the sorts of management tools folks use to automate this type of configuration, both initial setup, and ongoing management (system updates, user application updates, configuration changes, etc). anyone care to suggest any such tools, maybe some real-world pros and cons? of course, being centos, I prefer FOSS tools. for various reasons, this environment likely will NOT be virtualized (although I may emulate a test setup with vmware). -- john r pierce N 37, W 122 santa cruz ca mid-left coast

Update to CentOS 6.0 without CD/DVD reader
by Timothy Murphy 02 Sep '11

02 Sep '11

I've had a disaster on my home network server; the partition table on the disk containing / has become corrupted, and testdisk has not enabled me to recover the table. If anyone can help with this I should be grateful. However, that is not what I am writing about. I've installed a substitute box - and HP MicroServer - which by a miracle has CentOS-5.6 installed on it. Now I'm wondering what is the best way to install CentOS-6, given that there is no CD/DVD driver on this machine. I have access to the internet, so I can download the CD/DVD . I know I could install through a USB stick; I'm just wondering if there is a more direct route. I should look this up, but I'm rather weary after installing dovecot, httpd, etc, and thought I'd take a short cut by asking you gurus. -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

(c 5.6) Running 2 versions of Apache ?
by Always Learning 02 Sep '11

Just wondering how to run 2 versions of Apache on the same server, listening on different IPs and both on port 80. Does one give them, the httpd, different names and effectively duplicate most of the Apache set-up ? I use Apache;s virtual hosts facility for normal purposes but this is for a different project. Thank you. Paul.

Scientific Linux 6.0 released (based on RHEL 6.0)
by Arun Khan 01 Sep '11

I know this is the CentOS list. However, as there has been some interest in CentOS 6.0 (RHEL 6), I thought I'd share the news here. Scientific Linux 6 is based on RHEL 6 with add-ons for scientific computing. FWIW, the Admin tools etc. are pretty much the same as in RHEL, so are the base packages.

CentOS 6, KDE 4: bad DNS traffic
by Michael D. Berger 01 Sep '11

01 Sep '11

On my new CentOS 6, KDE 4, running WireShark I see what appears to be frequent nonsensical DNS queries, for example: "settings-personal.desktop" and "settings-system.desktop". The DNS response is always:"No such name". Do tell! These appear especially when I click on things on the KDE menus. On my old CentOS 5 box, on the same LAN, I see no such thing. I note that I have replaced the original /etc/hosts with my own. Might these have been resolved in the original? Thanks for your comments. Mike.

Help integrating CentOS 6 with existing network login infrastructure
by Alfred von Campe 01 Sep '11

01 Sep '11

I've updated my kickstart configuration files to work with CentOS 6 and am most of the way there integrating a CentOS 6 system into our LDAP/NIS environment. My authconfig line in the kickstart file is as follows: authconfig --enablemd5 --passalgo=sha512 --enablenis --nisdomain=XXX --nisserver=nis.XXX.com --useshadow --enablekrb5 --krb5realm=XXX.COM --krb5kdc=ldap.XXX.com --krb5adminserver=ldap.XXX.com This is virtually identical to the authconfig line I was using in CentOS 5. My issue is that users cannot log in with their network (NIS) usernames and passwords. If I log in as root, I can do a "su - username" and get the user's automounted home directory with the correct uid/gid, but if I try to log in as the user, or do a "su - username" as a non-root user and have to enter the password, authentication always fails. The entries in /var/log/secure just say "su: pam_unix(su-l:auth): authentication failure". I'm not a pam expert and don't know how to debug this. Anyone else run into this and/or know what might be the problem? This works just fine in CentOS 5. Alfred
