Re: [CentOS] Tracking updates
by Per Qvindesland 11 Jun '09

11 Jun '09

Hi Ocsinventory http://www.ocsinventory-ng.org/ might be considered if not then I could also recommend Spacewalk http://www.redhat.com/spacewalk/ for something like this both runs well on Centos Per E-mail: per(a)norhex.com [1] http://www.linkedin.com/in/perqvindesland [2] --- Original message follows --- SUBJECT: [CentOS] Tracking updates FROM: Martin Spinassi TO: "CentOS mailing list" DATE: 10-06-2009 17:45 Hi all, I don't know if exists what I'm searching for, or just making the wrong questions to google. I'm searching some kind of tracking system to software updates. If one server is administrated by more than 2 persons, having control of what updates have been installed, and what version of that application is running after the update. Making manual documentation is ok for one server, but doing this for several servers is a big amount of time, and relies on the admin to have the time to do so, but automating this would be great. I someone doing something to have track of the updates? Any recommendation? Cheers, Martín _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos Links: ------ [1] http://webmail.norhex.com/# [2] http://www.linkedin.com/in/perqvindesland

Bind krb5kdc only to eth1 and not also to ppp0
by Olaf Mueller 11 Jun '09

11 Jun '09

Hello, if starting /etc/init.d/krb5kdc, kerberos binds to eth1 and the *current* ip of ppp0. # netstat -nap | grep :750\\b udp 0 0 91.9.220.166:750 0.0.0.0:* 3180/krb5kdc udp 0 0 192.168.0.1:750 0.0.0.0:* 3180/krb5kdc # netstat -nap | grep :88\\b tcp 0 0 0.0.0.0:88 0.0.0.0:* LISTEN 3180/krb5kdc udp 0 0 91.9.220.166:88 0.0.0.0:* 3180/krb5kdc udp 0 0 192.168.0.1:88 0.0.0.0:* 3180/krb5kdc Since my internet provider changes the address of ppp0 for every 24 hours and since the last start of /etc/init.d/krb5kdc was 10 days ago (with the last reboot of my server), kerberos still binds to the old ip of ppp0. How can I force krb5kdc to bind *only* to my local address 192.168.0.1 (eth1) and not to bind also to the current ip of ppp0? Thank you! regards Olaf

External SATA enclosures: SiI3124 and CentOS 5?
by Benjamin Smith 11 Jun '09

11 Jun '09

Tired of "little problems" trying to keep 7 drives working in an old desktop computer, I'm considering an external SATA drive enclosure with a controller card based on the Sil3124. http://www.ipcdirect.net/servlet/Detail?no=152 I'm a bit concerned about long-term support, namely that the company's driver page only lists drivers through RedHat 4. http://www.siliconimage.com/support/searchresults.aspx?pid=27&cat=3 Does anybody else have experience with this controller? How has it been for you? If you have experience with an external SATA enclosure(s), what did you use and how did it work for you?

OT: Windows Vista Tablet PC linux alternative
by Sorin Srbu 11 Jun '09

11 Jun '09

Hi all, I have this tabletpc one of my bosses insisted on buying. The machine runs Windows Vista TabletPC Edition. As it happens I have a thousand and one problems with this POS operating system... I think the hardware is fine though, so it's not that. Would any of you guys know of some kind of linux-based alternative, preferrably available on or for CentOS, that can do the same hand-writing-on-screen-tricks as Vista Tablet does? Please excuse this off-topic post, but the frustration with Vista runs high over here right now. 8-/ Mail me privately if you feel this shouldn't be discussed on-list but want to hint me anyway.

yum --allow-downgrade and versionlocking not working
by Kai Schaetzl 11 Jun '09

11 Jun '09

with installed version 1.3.7 from rpmforge yum --allow-downgrade update rrdtool-1.2.30-1.el5.rf results in "no packages to update" yum --allow-downgrade install rrdtool-1.2.30-1.el5.rf says "already installed" So, how am I supposed to use --allow-downgrade then? I had to rpm -e --nodeps the newer packages to be able to install the older packages. Now I want to lock the package version. However, again, yum doesn't work as I read from documentation. After adding rrdtool-1.2.30-1.el5.rf perl-rrdtool-1.2.30-1.el5.rf to versionlock.list I get: Error: Package tuple ('rrdtool', 'i386', '0', '1.3.7', '1.el5.rf') could not be found in packagesack where I can't find any fix for. Interestingly, I'm also getting this error on a simple "yum update", that I haven't seen before: Error: Package tuple ('perl-DBD-mysql', 'i386', '0', '4.011', '1.el5.rf') could not be found in packagesack This package was removed quite some time ago the same way because downgrading didn't work. (This package wrongly obsoletes a base package.) What's going on here? Even yum clean all doesn't help.

munin stopped working
by Kai Schaetzl 11 Jun '09

11 Jun '09

Just noticed that my munin installation stopped showing any data after the last "big" update. I installed a lot of updates for CentoS, but there was also a munin update coming from rpmforge. However, in yum.log there is no munin listed. But I'm sure I updated munin to 1.2.5-2.el5.rf as well. Does yum log only the centos repo's? The problem seems to be with the creation of the graphs. When running munin-cron manually I get this output: No fonts found; this probably means that the fontconfig library is not correctly configured. You may need to edit the fonts.conf configuration file. More information about fontconfig can be found in the fontconfig(3) manual page and on http://fontconfig.org I don't know at all what I should do. Is anyone else running munin and hit and solved the same problem? Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com

grep/sed help

I am rsyncing and remotely doing some work based on a logfile from a windows box from a centos backup server. I get the output from a vss snapshot that has a section like this: * SNAPSHOT ID = {639ef5df-c933-4496-878a-ed57b9d52876} ... - Shadow copy Set: {427ac5db-21be-4c53-8ca4-24e7bac86a1d} - Original count of shadow copies = 2 - Original Volume name: \\?\Volume{787bdf7a-ccff-11dd-9866-806e6f6e6963}\ [D:\] - Creation Time: 6/10/2009 12:12:08 PM - Shadow copy device name: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy11 - Originating machine: milano.example.local - Service machine: milano.example.local - Not Exposed - Provider id: {b5946137-7b9f-4925-af80-51abd60b20d5} - Attributes: No_Auto_Release Persistent Differential * SNAPSHOT ID = {fb5996cf-a35b-4110-b83c-45f9c64a75f3} ... - Shadow copy Set: {427ac5db-21be-4c53-8ca4-24e7bac86a1d} - Original count of shadow copies = 2 - Original Volume name: \\?\Volume{787bdf7b-ccff-11dd-9866-806e6f6e6963}\ [E:\] - Creation Time: 6/10/2009 12:12:08 PM - Shadow copy device name: \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy12 - Originating machine: milano.example.local - Service machine: milano.example.local - Not Exposed - Provider id: {b5946137-7b9f-4925-af80-51abd60b20d5} - Attributes: No_Auto_Release Persistent Differential My current script only uses sed/grep but I never had to deal with this case where now I need to do something based on the grep'ed/sed extraction of the value of "SNAPSHOT ID" based on volume name "D:" or "E:"? To make my script work without rewriting it, is there a sed method to only take the "SNAPSHOT ID" if the text indented beneath it has "D:", then do the same and extract "SNAPSHOT ID" if and only if "E:" follows? Thanks for any help! jlc

Automounter (?) failing in CentOS 5.3
by MHR 10 Jun '09

10 Jun '09

I may have asked about this before, but I can't find any records of so doing in my saved mail (which includes almost everything I ever read or write): All of a sudden, I am not getting flash drives automatically mounted in CentOS 5.3 with GNOME - they are recognized by the hardware, but there seems to be a (new?) problem with the maps.

(However, I cannot mount it, or the other flash drives that also have worked flawlessly for months, with gnome-mount, which used to work as long as the device was visible. I can look at the partition tables on all three drives with fdisk -l, but no automount to /media/<whatever>.) How do I fix this? Thanks mhr

Things that fail over time (was Automounter (?) failing in CentOS 5.3)
by MHR 10 Jun '09

10 Jun '09

I'm starting a new thread on this because there are other failures I'd like to bring up, not _necessarily_ directly related to CentOS, but they all happen to me here. FTR: Linux mhrichter 2.6.18-128.1.10.el5 #1 SMP Thu May 7 10:35:59 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux (AMD 64x2 7750, 2.7GHz, 2GB memory, 900+GB disk, etc.) I had a meeting to go to last night, so before I left, I rebooted. When I returned, as I expected, my USB flash drives were all properly recognized (i.e., the default behavior worked). I have a number of scripts and aliases that "depend" on certain flash drive cognizance, but they all depend on indeirect references, so by changing, eg., my symlink to my "main" flash drive, everything that "depends" on it works just fine. Of course, after the reboot, I had to restore the original symlink, but I digress. This particular failure might not actually have been time related, although it seems like it because once it "began" to fail, it always failed. I tried all my USB ports, moved some connections around, and only the flash drives continued to fail - my printers were fine (I had to reset the hardware connection values in System->Administration->Printers, but that's normal with a USB disconnect/reconnect anyway if the ports are different. I got onto this because I was using a USB extension cable for most of my connects with the flash drives, and I was seeing some strange behavior there, e.g., when I jiggled the flash drive, it would start acting as if it had been unplugged and replugged. I actually went through and tested all my USB ports, some with and without the extension cable, and I found one that just doesn't work at all (!), but the behavior was consistent, except that I haven't retested that extension cable yet - not sure I want to.... Another issue I'm seeing that is most clearly a time-related failure is with flash videos in SeaMonkey. I'm running: Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9.1b3pre) Gecko/20090223 SeaMonkey/2.0a3 with most of the usual plugins, including the Adobe Shockwave Flash 10.0 r22 plugin. This is the i586 aka 32-bit version. I tried using the 64-bit version, which I _think_ I got from rpmforge, but it just doesn't work right, and it can't be installed simultaneously with the 32-bit version. (I'm also using nspluginwrapper, of course, which is really nice.) The problem is that, after some indeterminate period of time, usually overnight, the flash videos stop working properly. They either load for about 2 seconds and hang, or they play for 10-30 seconds with no sound, then a burst of high-speed "catch-up" sound, then either nothing or the echoes of the last fragment of sound, and so on. Frequently, even when I close the offending tab, the sound takes up to a minute or two to stop its echoes. The only solution I've found is to close SM altogether and restart it. Then, all is well. I realize that a) this isn't a CentOS issue per se, and b) I'm using the 2.0 alpha test pre-release version of SM. However, I have found, through bitter experience and regret, that the standard release of SeaMonkey 1.x is worse. Now, I know there are some who will say "Use Firefox," but, frankly, I really don't like the way too many of its "featuers" work, and I really, _really_, REALLY prefer (a mild word for it) the SeaMonkey/Netscape behaviors. I should also note that it doesn't matter how many flash videos I play that work, 0 or 1 or a dozen, once I hit that one that doesn't, it's close all tabs and restart. It's annoying, even when I just close the thing SM and let its semi-automatic re-open all tabs on restart, because usually that doesn't reestablish existing logins (it's kind of intermittent there), and I am usually logged into Yahoo and Gmail all the time. There are also other failures I've seen that I can dimly recall and that I thought at the time were time-related, and, miraculously! a reboot solved them all, at least until the next time. I don't remember any of the specifics of those, and I haven't adopted the practice of making notes on ALL of them yet, but it's just my (primary) desktop, and I haven't seen anything remotely catastrophic in those areas. Yet. So what? I was wondering if anyone else had any thoughts on issues of this nature (time-related failures). Thanks. mhr
