yum yum or not?
by Shaun 30 Apr '12

30 Apr '12

Hi all, I'm a bit of a newbie to CentOS though not Linux in general. I come from an apt-get package management mentality and I've had a few issues where package management actions haven't quite done what I'd expect. So I'm guessing it's user error! :) I installed GNOME and then decided that I wanted to install Xfce to try it out. I decided to then remove it with just 'yum remove' after playing with it a bit. It seemed to uninstall a lot of GNOME stuff (presumably that they had in common) and so the next time I tried to use GNOME it looked different and was missing a few components. Should I have just reverted the install of Xfce to undo it so that those dependencies would've have been touched or is this just how yum works?

NTLMv2 compatibility in Samba 3.0.33 standard packages
by Andrew Reis 28 Apr '12

28 Apr '12

Good afternoon/morning/evening everyone, I've been running into the problem of clients using Windows 7 with CentOS 5.X and file/printer sharing. Correct me if I'm wrong, but the stand samba-3.0.33-x.x.x packages DO NOT provide compatibility with Windows Vista/7. I've had to manually compile samba from source or use the samba3x packages to fix the problem. Just wondering if we're ever going to have the NTLMv2 subroutines compiled into the update/centosplus repo packages. Thanks, -- _ANDREW REIS_ MCTS, Network+ Software/Networking Microsoft Windows Support/Webmaster DBMS Inc.

iptables drop on virtual host
by Bob Hoffman 28 Apr '12

28 Apr '12

Does this work? adding DROP to iptables on the virtual host's iptables, before the phys bridge....will it prevent those ips from getting to the bridged part of iptables? Or would a different syntax be used? -A INPUT -s 66.77.65.128/26 -j DROP -I FORWARD -m physdev --physdev-is-bridged -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT

imagemagick convert/display eps file no decode delegate
by Tony Schreiner 27 Apr '12

27 Apr '12

I am finding on all my CentOS 5.8 systems (all fully updated but a variety of package mixes) that the display or convert commands from ImageMagick are unable to handle eps files. I get error output as follows, curious if anyone else sees this $ convert rna.eps rna.epi convert rna.eps rna.epi Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 Error: /undefinedfilename in (72x72) Operand stack: Execution stack: %interp_exit .runexec2 --nostringval-- --nostringval-- --nostringval-- 2 %stopped_push --nostringval-- --nostringval-- --nostringval-- false 1 %stopped_push Dictionary stack: --dict:1154/1684(ro)(G)-- --dict:0/20(G)-- --dict:70/200(L)-- Current allocation mode is local Last OS error: 2 GPL Ghostscript 8.70: Unrecoverable error, exit code 1 convert: no decode delegate for this image format `rna.eps'. convert: Postscript delegate failed `rna.eps'. convert: missing an image filename `rna.epi'. ImageMagick 5.2.8.0-12.el5 ghostcript-8.0-14.el5 the equivalent GraphicsMagick command gm convert does work This is a recent development, but I can't say how recent Tony Schreiner

Help with software raid + LVM on Centos 6
by aurfalien 27 Apr '12

27 Apr '12

Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it for swap) md2 All remaining space (use it for /) 2) Created two physical LVMs, one on md0, the other on md1. 3) ? This is were I am confused, do I create two LVM volume groups? I was thinking that my primary LVM can be ~1TB and that my other LVM which I snapshot to can also be ~1TB. Anyways, I am very green on this topic as I usually do hardware raids but I don't have that option. Thanks in advance, - aurf

Re: [CentOS] yum yum or not?

I have only this suspicion. It may be that yum history undo only rolls back the changes actually made by the previous yum update/install since it 'knows' that the system environment has not changed in the interim. Whereas yum history remove, since it has to cherry-pick packages from a possibly changed environment, instead removes rpm dependencies based on the package specs of the items directly added by the original yum command, whether these were installed in that transaction or not. But, this is only a guess. -- *** E-Mail is NOT a SECURE channel *** James B.

More on the ATA sense error
by m.roth＠5-cent.us 27 Apr '12

27 Apr '12

AFAIK, no one's responded to me about whether I should just turn off smartd. At any rate, here's more info: this server only started spitting Apr 25 07:47:50 <server> kernel: sda: Current [descriptor]: sense key: Recovered Err ror Apr 25 07:47:50 <server> kernel: Add. Sense: ATA pass through information availl able Apr 25 07:47:50 <server> kernel: Apr 25 07:47:50 <server> kernel: Descriptor sense data with sense descriptors (in hh ex): Apr 25 07:47:50 <server> kernel: 72 01 00 1d 00 00 00 0e 09 0c 00 00 00 00 00 00 Apr 25 07:47:50 <server> kernel: 00 4f 00 c2 40 50 for every drive - and it has four - right after updated to the most current kernel 2.6.18-308.4.1.el5 #1 SMP and rebooted. So one question becomes three: a) should I turn off smartd? b) should I reboot to the previous kernel, and see if it keeps up? c) is this a known bug? mark
