how to inject a kmod driver from elrepo into kickstart
by psavoie1783 07 Dec '13

07 Dec '13

Hi All, I have a marvel chipset for my wired laptop connection. It uses the kmod-sk98lin-10.93.3.3-1.el6.elrepo.x86_64.rpm driver at elrepo. I would like to use this driver to activate the wired connection to kickstart my laptop as I have pxe booting set upon my home network. Could anyone please enlighten me as to how to get the drivers/firmware from this package loaded on my laqptop so I can use kickstart to load the OS, please? Thank you for your time, Phil -- To err, is human To never grow up, is divine _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

DMAR Problem since 6.5
by Sebastian Marten 07 Dec '13

07 Dec '13

Hello List, I updated my server to CentOS 6.5. When i boot the system with the new kernel: 2.6.32-431.el6.x86_64 I get repeating the following message: dmar: DRHD: handling fault status reg 3 dmar: DMAR:[DMA Read] Request device [00:02.0] fault addr 1fc00000 DMAR:[fault reason 06] PTE Read access is not set I use a Intel Core i5-3550 CPU with vt-d enabled to use a DVB-S Card inside a Windows VM (kvm). With the old 6.4 Kernel all works (2.6.32-358.23.2.el6.x86_64) lscpi shows this: [...] 00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09) [...] Is this a problem with the intel driver or anything else? Regards, Sebastian Marten

Dragging app between workspaces not working
by Wes James 06 Dec '13

06 Dec '13

When I try to drag an app between workspaces, it doesn't move. I'm using compiz. When I put an arrow over an app in the workspace panel viewer (whatever that is called), it says click to start dragging, but no go. Any ideas? Thanks, -wes

Nux! Interesting point, something I didn't know. Fortunately in my case there are no db files involved directly, just db dumps wrapped in a tarball along with other associated stuff, sent from other servers. I would expect that lsync'ing db files could be a nasty non-stop process if the database is constantly being updated, so using db tools for replication would be best, configuring inotify/lsyncd to ignore the db directories. I believe by default that lsyncd instructs rsync to do whole-file transfers, so a large db could be a real problem. Thanks for the important heads-up!

Third-party SATA-RAID cards suggestions
by Sorin Srbu 06 Dec '13

06 Dec '13

Hi all, Would anybody care to suggest a third party SATA-RAID card that works out of the box with CentOS 6, without having to jump through hoops to make it work? The card should preferably be able to connect ten harddrives, but I guess three four-port cards should work as well. There's no need for anything fancy really, as long as I can create a single big software-raid on it at CentOS install-time. So far I've tried a Highpoint RocketRAID 2740 and a LSI 9201-16i without too much success.

To discard... or not to discard...
by John Doe 06 Dec '13

06 Dec '13

Hi, I just recently read a post about SSD triming (discard vs fstrim): http://www.howtogeek.com/176978/ubuntu-doesnt-trim-ssds-by-default-why-not-… far I used discard on all my SSDs. Now I am wondering if it is really worth it to switch them all to a crontabed fstrim... Anyone made the switch yet? Thx, JD

ADMIN issue - manitu
by m.roth＠5-cent.us 06 Dec '13

06 Dec '13

I've been blocked twice this morning, and removed myself once - the first time, by the time I got to work and looked at the list, it was already gone. My hosting provider works with those jerks at manitu. I've ranted a number of times over the years at why their method is a *lousy* method for blocking spam in the second decade of the 21st century. Now this: here's another argument as to why the CentOS list should stop using them... when I went to remove myself, the email that told me I'd been blocked, also said who'd reported my mailserver (that is, hostmonster's mailserver) as sending spam was someone at selfip.biz. Go do a whois on them - it's someone at home, using dyndns, not an open obvious company. This means that anyone who gets annoyed at *anyone* served by any ISP can report them, and block everyone at that ISP. Go ahead, tell me this is *reasonable* in 2013. mark

Re: [CentOS] Fwd: 64bit centos and wine
by Igor Littig 06 Dec '13

Thanks, I was able to upgrade yum by deleting some mirrors which I didn't need slready. But I still cannot install wine. When I'm running configure script I'm getting "checking whether gcc -m32 works... no configure: error: Cannot build a 32-bit program, you need to install 32-bit development libraries." However, I've got "libstdc++-4.4.7-4.el6.i686" installed. Maybe "configure" search the lbraries in a wrong place ? 2013/12/6 Reindl Harald <h.reindl(a)thelounge.net> > other mirrors, some outdated, some not > currently CentOS 6.5 is reaching the users > > try downgrade the x86_64 version temporary > or "rm -rf /var/cache/yum/*" to hopefully > catch a different mirror > > i have not seen gnutls-2.8.5-15.el6.x86_64 here > by myself - so this is interesting, maybe this > one is very recently packaged > > Am 06.12.2013 10:12, schrieb Igor Littig: > > ---------- Forwarded message ---------- > > From: Igor Littig <igor.littig(a)gmail.com> > > Date: 2013/12/6 > > Subject: Re: [CentOS] 64bit centos and wine > > To: Reindl Harald <h.reindl(a)thelounge.net> > > > > > > I've been trying to do "yum upgrade" right now, but I'm getting the same > > multilib error with "gnutls" package and it stops > > "gnutls-2.8.5-15.el6.x86_64 != gnutls-2.8.5-10.el6_4.2.i686". > > > > 2013/12/6 Reindl Harald <h.reindl(a)thelounge.net> > > > >> Am 06.12.2013 08:10, schrieb Igor Littig: > >>> Thanks for the response, but the link did not help.

64bit centos and wine
by Igor Littig 06 Dec '13

06 Dec '13

Hello everyone. Has anybody ever tried to install 32bit wine to 64bit centos. I was able to run 64 bit wine, but some of mine application require 32 bit wine, but I cannot install it. It says to install 32bit development libraries at first. Does it make sense, what I'm doing ? I will be really appreciated any help. Cheers Igor
