ATI Radeon IGP 350M resolution problems
by Robert Moskowitz 29 Mar '06

29 Mar '06

My HP 4010 and the IGP 350M video card. I can only get it to go into 800x600 mode. At one time, Resolution Display (gnome desktop) was giving me an option of 1024x768 and if I selected it the monitor went crazy. Now I don't even get that higher resolution as an option. I have searched far and wide for information on this card and the Radeon linux driver. No help at all. My /etc/sysconf/hwconf has: class: VIDEO bus: PCI detached: 0 driver: Card:ATI Radeon IGP330M/340M/350M desc: "ATI Technologies Inc Radeon IGP 330M/340M/350M" vendorId: 1002 deviceId: 4337 subVendorId: 0e11 subDeviceId: 005a pciType: 1 pcidom: 0 pcibus: 1 pcidev: 5 pcifn: 0 I might suspect that changing one of those values will give what I want. But I cannot find any information on what this all means. I have also read where some 3x0M owners have switched to the generic VESA driver with better success. I tried that and did not get a 1024x768 option to even try. Oh, I also tried the SystemTools -> Display utility, (this is what I used to switch drivers) and it also did not offer 1024x768. help? Pointers?

Anaconda seems to exclusively build off of the hdlist, so you would have to rebuild it if you want to come out of the anaconda install with a fully patched system. I do this for Centos4 with no major problems. If you like, I can send you the commands that you need to run to do this. I actually keep a full package respository locally for Centos, and nightly pull down all the updates, and rebuild the hdlist, and yum headers. When I build servers, I use kickstart off of my own repository. 0 -> fully patched centos4 server in 5 - 10 minutes, depending on what is installed =). I then keep servers updated with yum, off of the same repository. > > My goal is to get away from the need to download 200+ megabytes of > updates after each install.

Method for autoinstalling new updates at install time (or very near to it)
by Jay Lee 29 Mar '06

29 Mar '06

I have CentOS 4.3 as well as RHEL4u3 and FC5 setup on my PXE/HTTP Server automating the install process. However, I'd also like to apply any post update RPMS during installation also. Is there any easy method to do this with out having to recreate the hdlist and other installation files? My desire would be to have a updates directory that I can put packages into and CentOS would check to see if a newer version of the RPM exists in /updates. Any thoughts? My goal is to get away from the need to download 200+ megabytes of updates after each install. I know I could setup my own yum updates server and then point each new install at that instead of the mirrors but I wanted something slightly more automated. Can anyone else tell me how their doing this? Jay

AIDE Reports changed:/boot/grub/stage2
by John Thomas 29 Mar '06

My daily AIDE report suggests Grub's stage2 file has changed. Could I trouble you for your opinion about how concerned I should be and what to do if your concern is moderate or higher?

dovecot vs Cyrus-Imapd
by Bob Pierce 29 Mar '06

29 Mar '06

I'm just preparing to build a new mail server for use at an ISP handling over 10,000 mailboxes and several domains. We're currently using Qmail, but we'd like to move away from that since we have now changed our inbound mail systems over to Postfix. Postfix will be receiving the mail, and I'm trying to decide between Dovecot and Cyrus-Imapd for the POP & IMAP service. Does anybody have any advice or opinions about which of these two packages would be better for a large installation. I'd prefer if the package could tie into MySQL for user authentication, and all mailboxes will be virtual in the sense that they won't have local system accounts. Thanks for your help. Bob.

Server spontaneously rebooting under RHEL-4
by Benjamin J. Weiss 29 Mar '06

29 Mar '06

Hey, y'all! :) I've got an RHEL-4 server (yep, I know it's not CentOS, but hey we gotta send some money RH's way to keep CentOS up and going! ) that's running Oracle 10g. This same hardware worked just fine for over a year running RHEL-AS-2.1 and Oracle 9i. Now we're getting spontaneous reboots when running oracle processes that eat up a bunch of resources. I don't know where to go from here. It's got dual hyper-threading processors set to hyperthreading mode, and I understand that the 2.6 kernel used to have HT issues, but I thought that'd been solved. The kernel we're running is: 2.6.9-22.0.2.ELsmp (yeah, not the latest, I haven't had a chance lately to test and update the patches). I think the kernel settings are correct, what with 4gigs of ram: [root@sibrsdbs etc]# cat sysctl.conf # Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and # sysctl.conf(5) for more details. # Controls IP packet forwarding net.ipv4.ip_forward = 0 # Controls source route verification net.ipv4.conf.default.rp_filter = 1 # Do not accept source routing net.ipv4.conf.default.accept_source_route = 0 # Controls the System Request debugging functionality of the kernel kernel.sysrq = 0 # Controls whether core dumps will append the PID to the core filename. # Useful for debugging multi-threaded applications. kernel.core_uses_pid = 1 # oracle settings kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 #fs.file-max = 65536 net.ipv4.ip_local_port_range = 1024 65000 net.core.rmem_default=262144 net.core.wmem_default=262144 net.core.rmem_max=262144 net.core.wmem_max=262144 I don't know how to look for the core dump, if there was one. I don't see anything named 'core' in the /root directory. I'm sucking wind, any suggestions? Thanks! Ben

High CPU usage for migration kernel process
by Andy Armstrong 29 Mar '06

29 Mar '06

I've got a CentOS 4.3 box here which is exhibiting crazy (I think) CPU load on one of the four migration kernel processes: # ps ax | grep migration 2 ? S 0:08 [migration/0] 4 ? S 112:23 [migration/1] 6 ? S 2:48 [migration/2] 8 ? S 0:11 [migration/3] It's running kernel 2.6.9-34.ELsmp. Does anyone have any idea what might cause that? Thanks :) -- Andy Armstrong, hexten.net

Another server hosed
by centos＠911networks.com 29 Mar '06

29 Mar '06

Hi, Just upgraded a remote 4.1 server [basically Samba] with yum update. Went through the process and every showed OK, when I did a restart, the only thing working is ping. I could ping it, but that's it. Could not connect anymore through SSH, could not connect through SMB. My smb.conf is still there and it still shows my settings. Testparm -L reports the correct info, but nobody can connect. I now have the server being shipped back. Anybody also having problems? -- Thanks http://www.911networks.com When the network has to work
