MySQL performance drop with FC2 kernels
by N T 30 Nov '04

30 Nov '04

I am seeing that performance using MySQL 4.1.7 drops by a significant amount if I use a FC2 kernel (2.6.8-1.521smp or 2.6.9-1.6_FC2smp) compared to running a stock 2.6.9 kernel downloaded from kernel.org. The vanilla kernel was compiled using the i686-smp config that FC2 used. I see similar issues when running MySQL 4.0.xx. All MySQL versions were installed from the RPMs available from <http://www.mysql.com>. The benchmark being used to measure performance was RUBiS <http://rubis.objectweb.org/>. While vanilla 2.6.9 can service ~220 reqs/s, FC2's version of 2.6.9 can only deliver ~120 reqs/sec. I have a Dell Poweredge with a hyperthreaded Pentium IV. However, I am not sure what other information might be relevant to narrow this problem. There was a thread on FedoraForum.org <http://www.fedoraforum.org/forum/archive/index.php/t-20064.html> about a similar problem but I did not see any resolution there. Any ideas? Thanks, Niraj

Anyone have pointers to bugzilla rpm/srpm that might work on FC3? I've checked the usual suspects - but couldn't locate it there Thanks, Satish yum --enablerepo=dag --enablerepo=atrpms --enablerepo=freshrpms --enablerepo=fedora-us list *bugzilla*

Audio CDROM problems...
by John Burton 30 Nov '04

30 Nov '04

Greetings, I've been having a bit of a problem with audio cdroms on FC3. I am trying to "rip" some cds and store them on the hard drive of my laptop (gotta have some tunes when traveling). The problem I noticed is that after several CDs I couldn't eject the cd anymore. The "eject" button on "grip" wouldn't work, and the hardware eject button on the CD drive would not work (had to get out the old paper clip and force it to open). No, I wasn't being impatient, I have grip configured to eject upon completion and it wouldn't. I noticed in the /var/log/messages file that prior to me trying to eject the CD, there were a series of error messages for "hdc" of the form: Nov 30 15:48:37 traveler kernel: hdc: command error: status=0x51 { DriveReady SeekComplete Error } Nov 30 15:48:37 traveler kernel: hdc: command error: error=0x54 Nov 30 15:48:37 traveler kernel: ide: failed opcode was 100 Nov 30 15:48:37 traveler kernel: end_request: I/O error, dev hdc, sector 0 Nov 30 15:48:37 traveler kernel: Buffer I/O error on device hdc, logical block 0 Nov 30 15:48:37 traveler kernel: hdc: command error: status=0x51 { DriveReady SeekComplete Error } Nov 30 15:48:37 traveler kernel: hdc: command error: error=0x54 Nov 30 15:48:37 traveler kernel: ide: failed opcode was 100 Nov 30 15:48:37 traveler kernel: end_request: I/O error, dev hdc, sector 4 Nov 30 15:48:37 traveler kernel: Buffer I/O error on device hdc, logical block 1 Nov 30 15:48:38 traveler kernel: hdc: command error: status=0x51 { DriveReady SeekComplete Error } Nov 30 15:48:38 traveler kernel: hdc: command error: error=0x54 Nov 30 15:48:38 traveler kernel: ide: failed opcode was 100 Nov 30 15:48:38 traveler kernel: end_request: I/O error, dev hdc, sector 8 Nov 30 15:48:38 traveler kernel: Buffer I/O error on device hdc, logical block 2 Nov 30 15:48:38 traveler kernel: hdc: command error: status=0x51 { DriveReady SeekComplete Error } Nov 30 15:48:38 traveler kernel: hdc: command error: error=0x54 Nov 30 15:48:38 traveler kernel: ide: failed opcode was 100 Nov 30 15:48:38 traveler kernel: end_request: I/O error, dev hdc, sector 12 Nov 30 15:48:38 traveler kernel: Buffer I/O error on device hdc, logical block 3 After seeing these in /var/log/messages, I was unable to eject the cd except via the trusty paperclip. I noticed that if I insert the CD before I start grip, I get these messages immediately when I insert the audio cd. If I start grip first, and then insert the audio cd, I don't get the messages right away, but instead get them sometime later. It seems as though "hotplug" or something is trying to mount my audio cd as a filesystem. I thought FC3 could recognize audio cds and not have a problem with them... any help would be greatly appreciated.. John

About VNC
by Jarkko Elfving 30 Nov '04

30 Nov '04

Hi... I've some questions about VNC. I'm never been used it before. Friend of mine (under my eyes, he's very, very good Linux user - I'm not so good (yet :))) had tried to configure the VNC on Fedora Core 2 - with no success. He had read everything about it, but still he doesn't get it where something went wrong. VNC session on Linux-to-Windows works fine without any problems, but not on Linux-to-Linux. I've read some messages of yours but still I don't know how it works. Somewhere I found a discussion where sayed that there must be an access in the firewall (I understand that so, that default firewall settings does not accept any VNC connections to anywhere). Can you help me to build working configurations to VNC. Then I can help my friend on with it. Thanks. BTW: Some of you uses a PGP signatures, what keyserver do you usually use? -- Jarkko Elfving <jarelf(a)ebaana.net>

experiences with an upgrade
by Mike Zingale 30 Nov '04

30 Nov '04

Hi, I just recently upgraded my system to FC3 from FC1. It is important to note that the FC1 install was also an upgrade from Redhat 9, so some of the experiences I have run into might be from that. Hopefully some of this will help anyone else who always does upgrades instead of fresh installs. Some observations: 1. system-config-soundcard was not installed. After the upgrade, I had no sound, despite all the proper lines being in /etc/modprobe.conf yum install system-config-soundcard and then running that seems to have fixed this. 2. the menus were all messed up. Under the systems menu, was an Applications, Games, Internet, etc. submenu. In fact, the Games menu appeared under a lot of the categories. I eventually tracked this down to the new Gnome looking in /etc/X11/applnk and putting any directories in there in (seemingly) random places in the menu. Deleting these made the menus much nicer. 3. evolution was not installed. Clicking on the mail icon on the Gnome panel just brought up an error and then the default applications dialog 4. even after updating udev to the latest version, the Nvidia closed-source driver still has problems after reboots. Maybe this is still the status of this driver, but I thought I read in the archives that the new udev made things happy again. So far, it seems a little faster than FC1 on this machine (PIII-733MHz). ------------------------------------------------------------------------------ Michael Zingale UCO/Lick Observatory UCSC Santa Cruz, CA 95064 phone: (831) 459-2277 fax: (831) 459-5265 e-mail: zingale(a)ucolick.org web: http://www.ucolick.org/~zingale ``Don't worry head, the computer will do our thinking now'' -- Homer

As William Hooper posted, you can access the physical remote desktop with VNC. It's great for training and tech support purposes, but IMHO you would rarely want to remotely access your own machine in this way. It is less secure (someone walking by can see and affect what you are doing), performance is worse, and mismatched screen resolutions can cause problems. You probably want a virtual normal desktop. To get that, just edit the xstartup script in your .vnc directory. Find the line that says: # Uncomment the following two lines for normal desktop: and follow its advice. --Stewart

OT apache question
by Michael Weiner 30 Nov '04

30 Nov '04

Sorry to be slightly off topic, however, i am trying to come up with a good/efficient redirect in apache to basically take ALL requests to the webserver and redirect them all to /index.html - except of course /index.html requests themselves. I have been able to get RewriteRule ^.+$ http://www.domain.name/index.html [R] to work however that also matches /index.html. And yes, i have read and am presently reading the apache org rewrite guide :) I know this isnt rocket science but the answer is not striking me in the face - obviously a lack of caffeine this morning. Does any one on the list have an answer? Thanks in advance Michael Weiner
