Re: [CentOS] Best way to configure proprietary NVidia driver on CentOS ?
From: Nicolas Kovacs cont...@kikinovak.net What's the best (cleanest, easiest, whatever) way to install the proprietary NVidia driver on CentOS 5.5 ? Usually I'm using the RPMForge 3rd party repo and compile the odd missing package myself from a Fedora SRPM. But the nvidia packages look a bit like a mess. DKMS has errors in the startup script (looking for a nonexistent log_action_msg and the likes), so I wonder if it's best to just download the driver from nvidia.com and build it myself. I use dkms-nvidia-x11-drv and it works fine between kernel updates... While I know kmod is said to be better, last time I tried it, I failed to make it work. Maybe I will retry kmod later...

Re: [CentOS] updating to gtk+ = 2.0
In that case: yum install gtk2 gtk2-devel Funny thing is those are already installed. However I require a later version of gtk+. I'm attempting to compile from source. CentOS comes with an old version of GTK 2. Most application these days require a later version of the library, so you have two realistic options: * Compile GTK from source and install it out of the standard library path, then specify the include paths for compiling and use LD_LIBRARY_PATH before running the application. * Use another Linux distritbution or wait for CentOS 6 There's another option that is not guaranteed to work, copy all the libraries you need from another Linux distribution (Fedora?) into a directory, use LD_LIBRARY_PATH and pray that it works with CentOS, but I would not place much trust on this option. I would personally go for the latter option as compiling a new version of GTK and its dependencies is not for the faint of heart, specially for something as obsolete (by choice) as CentOS. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] MacBook Pro and CentOS-5
Being a mac system admin and support specialist and CentOS guy. I can say you can always try using an external hard drive to boot the Mac off of and install CentOS on that drive to play around and test out all the drivers for video card, wireless, etc... I don't boot into CentOS but have it running in Parallels and it runs great. I also do recommend to get your Mac repaired too, just be sure to clone your hard drive off to an external drive before sending it into the shop.

Re: [CentOS] MacBook Pro and CentOS-5
This is off list topic, but I have seen weirdness in airport cards on macs especially when connecting to Apple's Airport. A cheap fix is to buy a 2nd wireless access point and make sure to use that in bridged mode so it is not acting as a router and wire that to your airport base station. I like said before trying using an external hard drive to install CentOS onto and try your wireless card and other hardware drivers.

That actually seems pretty unlikely, since a bazillion other people use the same drivers... Or at least it is a quirk of your setup that triggers the issue. Do you have wireless phones in the same frequency range nearby? I do, and see disconnects that I think are related in my d-link router logs but haven't seen any problems with connections being re-established from anything including my son's macbook. Have you used wireless in any other locations, and if so, do you always see the same problem? For one thing, a frequent occurrence is that I get a 'browser is offline' (in both Safari and Firefox) when opening a new tab, but the existing tabs in the same browser instance can visit new pages on existing connections!!?? How that works is beyond me but it happens, often. That doesn't make much sense but you are probably trying to reuse a socket that has received a reset - browsers open several sockets simultaneously and the others might not have been busy during the network disconnect. And it is the wireless NIC that I most need fixed. Right now I have to shut down the Airport and restart it to clear the problems. In itself this is no big deal, but I am just so tried of having to do this with such an expensive piece of kit. Do you mean disable the wireless NIC and re-enable (which sort-of makes sense) or doing something to the router? If you really have to restart the router, that's probably the source of the problem. If CentOS does not support the wireless in the Macbook then I am stuck with the sucker until I get up enough gumption to buy a Toshiba. Which is what I should have done when I allowed myself to be talked into the HP to begin with. Hardware is all pretty much the same - it either works or it doesn't. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] SSH keys question
All, I have 3 servers. All 3 are CentOS 5.5. All 3 have identical /etc/ssh/sshd_config files. I used ssh-keygen (with no arguments) to generate keys with no password. I then added all 3 id_rsa.pub keys to the authorized_keys file. With this set up, I should be able to ssh between all 3 boxes without needing a password. The problem is that one of the servers keeps asking for a password even with the keys set up. servera -- serverb No password serverb -- servera No password servera -- serverc Password serverc -- servera No password serverb -- serverc Password serverc -- serverb No password If they are all identical from an ssh standpoint (at least the authorized_keys, /etc/sshd_config, and UID for the user on all 3 hosts), why will serverc not play nicely with the other 2 Is there something else I should be checking?

AFAIK a kernel that is running ntpd and ntpd thinks has reasonably synced to the NTP server will, every _eleven_ minutes write the system time to the hardware clock, and you can't stop it without modifying the kernel or ntpd. All of those machines in question take their time via NTP from the same local server, and that server gets its time from a ntp pool. reasonable NTP setup.

Now, 39600s is 11 hours, which is (inc DST) *MY* offset from Greenwich. So what am I doing wrong? Running a Linux _Server_ as if it had to dual boot with windows. i.e. the hardware clock should be kept in UTC unless you need to boot the same machine with windows. The idea of running hwclock is to make sure that exactly the problem with dovecot does NOT occur, and ntp does not have a coughing fit when the hardware clock is not close to the correct time upon booting. The standard start script (/etc/rc.d/init.d/ntpd) does a ntpdate before running (which is what you see in your log above) to keep ntp from coughing. The last time I booted some of those machine was more than 200 days ago, so the hwclock will be skewed if I do not update it. I *WAS* beginning to think like the others, that the TZ file used by hwclock and by date don't match. However, I now *believe* I KNOW the source of the delta! IIRC the kernel magic (write system time to HC every eleven minutes) I was writing about earlier ... I don't think takes into account the local TZ, i.e., it ALWAYS works UTC. I would have to read the kernel source again to prove it, or suggest to you to try the following: 1) *remove* your cron job that called hwclock, because it is and will cause problems. 2) let the machine sync with the NTP server i.e., ntpdc -c kern |grep status returns something like: status: 0009 pll fll 2a) wait 12 minutes. 3) run: date -u ; hwclock --show --utc; date -u ; \ date ; hwclock --show ; date 4) run hwclock --systohc; \ date -u ; hwclock --show --utc; date -u ; \ date ; hwclock --show ; date 5) wait 23 more minutes 6) run date -u ; hwclock --show --utc; date -u ; \ date ; hwclock --show ; date if at 3 and 6 the utc versions of date and hwclock are in sync, then it is the ntpd synced kernel that is setting a utc time into the hwclock and you need to change the last line in /etc/adjtime to UTC instead of LOCAL. Otherwise a bit more thinking is in order. good luck. -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Xen dom0 support is going into the mainline 2.6.37 kernel, but there are still patches that are needed. Once the bugs have been ironed out, I suspect that CentOS support will follow soon after. There will be experimental kernels before then, but I would not recommend them outside of test environments.
