Upgrade 4.7 > 5.3 poorer 'performance'
by Tom Brown 20 Jul '09

20 Jul '09

Hi During a test upgrade of a number of hosts in a pool i have found that exactly the same JVM based app runs more efficiently on the 4.7 systems than it does on the 5.3 on identical hardware. Specifically the apps seems to exhibit about 10% more 'load' on the CPU's for the same workload - before i start digging deep has anyone seen anything similar ? thanks

CentOS, laptop & DLP
by MHR 20 Jul '09

20 Jul '09

I have an old Toshiba Tecra 8100 that I run CentOS on - it's running 5.3 although not completely up to date at the moment. About a year ago, a club I help administer bought a BenQ DLP so we could show movies and do other projector things more easily than lugging around a 27" TV set. It worked just fine, but the behavior of the system with it has changed over the year and I'm curious if anyone might know why. When I first connected the DLP, the laptop (and CentOS) recognized it immediately, and there was absolutely no trouble with it at all. I plugged it in, turned it on, hooked it up, and voila, it worked. Now the laptop doesn't recognize the DLP unless I plug it in either before booting, or reboot after it's plugged in, and I can't play with the <function>-F5 combination (that switches between LCD, DLP, LCD+DLP, no video) until I'm logged in unless I want to be stuck in whichever mode it lands in. I usually set it for both and wait until my login is complete, then I can flip between all the settings just fine. One of the things I really liked about CentOS with this DLP at first was that I did NOT need to reboot for the system to recognize and use the DLP, just like any other hot-plug add-on. I connect it via the external 15-pin video port, same as day 1. Am I missing something, like "be sure the projector is on (or off) when I connect it to the laptop? I think I've tried all possible combinations of this and it just doesn't function at all unless I (re)boot after the DLP is on and connected. The only change I know for certain that happened over this year is that I upgraded from 5.2 to 5.3, but I can't remember if this had anything to do with the change in behavior or not (I don't think so, but it's been over the course of a year...). Thanks. mhr

Gallery2 under CentOS-5.3
by Timothy Murphy 20 Jul '09

20 Jul '09

I asked about 18 months ago if gallery2 was available in any of the CentOS repositories, and it seemed that at that time it was not. However, there was some talk of putting it in epel or epel-testing. But I looked just now, and did not find it there. I actually installed gallery2 on my server by following the instructions at <http://codex.gallery2.org/Gallery2:Preinstaller>. But I've had a slight http problem on the server which might be related to gallery2 (wireshark seemed to show some odd calls on gallery2); so I was wondering if there was yet an official CentOS implementation? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College Dublin

good small registrar?
by Eugene Vilensky 19 Jul '09

19 Jul '09

Greetings, What are some registrars that members of this list have had good experience with? I was stepping through the godaddy checkout process, and being opted-in to a dozen different upsell features just left a bad impression. But I have no clue who else to go with. -Eugene

recent rsyslog package available for CentOS?
by Eric B. 19 Jul '09

19 Jul '09

Hi, I'm looking for a recent version of rsyslog. The yum repositories only show me a version that is 2.0.6. According to the www.rsyslog.com site, they are up to version 5 (dev), which means that I would think/assume that there would at least be v3 or v4 available somewhere. Does anyone know if/where I can find something more recent than 2.0.6? Thanks, Eric

Anyone have experience with using a Sensa Fuze mp3/ogg player on CentOS 5.x? I'm looking for a player that plays vorbis and isn't a M$/DRM/Apple slave and this one looks like a good one to buy. Thanks for any help!

How do I troubleshoot these restarts? I suspected hardware failure (power supply, cooling fans, etc.) but somehow the restarts happen way too periodically, so I have second thoughts on software as well. CentOS 5.3, fully updated. Btw, I don't have physical access to the machine until September, so diagnosing hardware is pretty limited atm. Only remote ssh available. I would really appreciate any advice on this! Best, :-) Marko
