Newer SANE packages for 5.9 ??
by fred smith 01 Mar '13

01 Mar '13

I just got a Canon Canoscan LiDE 210 scanner, which the SANE project pages say works "completely" with Sane. but what isn't obvious without a lot of digging is that the version of Sane in EL5 isn't new enough. it works fine with what's on my eeepc (Fedora 17) but not Centos 5.9. I've been messing around with building sane from source, but have not been fully successful, yet, so thought before butchering my system any further I should ask if anyone has (or can point me to) newer Sane packages for EL5?? Thanks!

Hello All, CentOS release 6.3 (Final) I am getting e-mails now where they are: Subject: Cron <root@www> /usr/share/spamassassin/sa-update.cron 2>&1 | tee -a /var/log/sa-update.log Body: http: GET http://daryl.dostech.ca/sa-update/asf/1387055.tar.gz request failed: 404 Not Found: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>404 Not Found</title> </head><body> <h1>Not Found</h1> <p>The requested URL /sa-update/asf/1387055.tar.gz was not found on this server.</p> <hr> <address>Apache/2.2.6 (Fedora) Server at daryl.dostech.ca Port 80</address> </body></html> Can anyone help me understand what is happening here?

2way authentication for SSH?
by Rudi Ahlers 06 Feb '13

06 Feb '13

Hi, Does anyone know of a stable / working "2way authentication" system for SSH, and even web authentication services? Most of the banks in South Africa have a system that, when you want to make a payment, they send you an SMS and you need to verify the action with a secret code which was SMS'd to you. gmail also has this. Does anyone know of a "universal" plugin / application that can be used with SSH and even websites like Wordpress / Joolma / Webmin / etc? Any pointer would be appreciated. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Cell: 082 554 7532 Fax: 086 268 8492

intel_iommu=on => No root device found
by Nils Caspar 04 Feb '13

04 Feb '13

Hi all, for some reaseon, my message wasn't published. Second try, this time without the giant attachment. I have an Intel server (SR2600URBRPR) in front of me. The disks in my server are connected via PCI card (Adaptec RAID 3405). Now I would like to passthrough a PCI-E graphics card to a KVM guest. As this requires Intel VT-d, I configured the following options in the BIOS: Intel VT for Directed I/O [Enabled] Interrupt Remapping [Enabled] Coherency Support [Disabled] ATS Support [Enabled] Pass-through DMA Support [Enabled] Everything works so far, but when I add intel_iommu=on to the kernel line of my grub.conf, Dracut gives my a kernel panic while booting. I added "rdshell" to the command line and extracted the boot messages via dmesg (http://nilscaspar.ch/centos-dmesg.log). I think the main problem is this: dracut Warning: No root device "block:/dev/disk/by-uuid/280234d1-dff5-4e04-b1ef-93d54cdcd825" found But I doesn't make sense to me... As soon as I remove intel_iommu=on, everything works again (except the passthrough :P). Regards, Nils -- nilscaspar.ch

skype not starting anymore, prelink issue?
by wwp 04 Feb '13

04 Feb '13

Hello there! I was running skype 4.1.0.20 on my 64-bit laptop for weeks (installed in /opt, from an official skype binary archive, plus few 32-bit stuff to get it working), when suddenly it stopped working, no way to start it: $ skype Fatal: QWidget: Must construct a QApplication before a QPaintDevice Aborted A quick search on the Internet brought some possible solution, basically configuring prelink to skip skype binary, uninstall skype, reinstall it. I was doubtful about uninstall/reinstall step since I didn't install it using a RPM but from a binary archive. Anyway I did it, restarted even the computer. No way to start skype. For now I'm stuck w/ an former staticQT 4.0.0.8 version of skype, which has no support for MSN accounts. Please note that I'm not using skype+msn because I want, but because I need to (@work). Did anybody ever solve this issue or has a clue about how to do it? Regards, -- wwp

How to extract one file from rpm using yum?
by Robert Moskowitz 01 Feb '13

01 Feb '13

I want to get the original version of /etc/clamd.d/amavis.conf from the amavisd-new rpm to get the defaults to submit a bug report. I could not figure out how to do this, so I did a reinstall, but it did not replace this file (whatprovides says it comes from this rpm). Is there a way to extract just the one file, and better yet, place it elsewhere than its regular destination? thanks

Centos 6.3 - which repos to use?
by James Freer 01 Feb '13

01 Feb '13

I've just installed v6.3 as a desktop (from Centos-6.3-i386-LiveCD.iso) and to get the hang of the Centos approach and then hope to move on to a server. I've been using linux *buntu for 5 years. Hope i don't sound like a nit but i've got a little confused with the repos. Hoping someone would be kind enough just to clarify. This installation is for stability whilst installing the latest versions available. a] What happens if i select these? I assume that Centos6 is correct so why these? In software sources i have checked; Centos6-base, Centos6-extras, Centos6-updates unchecked; Centos6-contrib, Centos6-media, Centos6-plus i did check these three and media wouldn't, and plus wanted to suggest installation kernel 2.6 [gulp]. Each unchecked without installing. Then we also have the same for 6.0, 6.1, 6.2? b] So which repos to use as i'm unsure where apps are i want to use like efax (ok that's in), yumex, pyrenamer, llgal, abiword. at present i'm not sure which repos to use other than the one's i've mentioned. I then started to look at the repos http://wiki.centos.org/AdditionalResources/Repositories Centos extras and plus -- are these the same as above? CS/GFS, Centos testing, Fast track, debuginfo, contrib, CR - would seem not applicable to me. 3rd party repos rpmforge (DAG), and EPEL seem likely other repos seem likely to replace core packages which wouldn't be applicable. Google RPM gets a "use with care". I used the google browser on *buntu from their website with no problems so i was wondering what the problem would be and whether to use this repoo or the website. The fact that a maintainer has made this repo suggests a reason rather than just convenience. c] Could one just use pkgs.org to install from? My google "centos abiword" threw up yet another repo 'puias' and this has the latest Abiword version 2.8.6. http://pkgs.org/centos-6-rhel-6/puias-i386/abiword-2.8.6-3.puias6.i686.rpm.… I could just install from pkgs.org/centos-6 it would seem? Point is the repos are maintained by an expert rather than folk just downloading. I was then confused further by this http://miles.isb.bj.edu.cn/2012/03/09/how-to-install-abiword-on-centos-6-x6… One needs to add epal and rpmforge just for abiword? Surely the dependencies would be in the same repo I'm sure all is quite simple really but i'd be grateful for the guidance before i mess up an installation. thanks

ACL/permissions question
by Boris Epstein 01 Feb '13

01 Feb '13

Hello listmates, If I have a regular, ACL-capable filesystem on Linux (say, ext4 or xfs) is there a way for me to establish the following: 1) There is a directory, say, /home/joe . It is owned by user joe . No one but joe (and root, of course) can read or write anything in this directory. 2) No one can change permissions on that directory, not even joe. In other words, in joe all of a sudden joe decided to open his directory up to the world (or the group he is a member of) by doing something akin to: chmod 777 /home/joe he would not succeed. Thanks in advance for any help. Boris.

I use to do this stuff 10 years ago and my brain just ain't what it use to be. Use to do my own builds for a number of apps, but doubt I could do a build now! > > THANKFULLY a reinstall does not touch modified config-files > BUT you get a warning from yum that whatever.conf was installed > as watever.conf.rpmnew >
