32bit versus 64bit memory usage?
by Christian Nygaard 29 Aug '06

29 Aug '06

I'm planning for new Centos 4 computers using the 64bit distribution and is wondering if there is a difference on how much RAM memory you should use on a 32bit versus 64bit operating system? Will processes such as for example KDE, Firefox use more memory on the 64bit architecture than on the 32bit and if so by how much as a rule of thumb? Kind regards, Christian

web based mail packages for CentOS
by James Marcinek 28 Aug '06

28 Aug '06

Hello Everyone, I was using OpenGroupware but just hosed my system. Since I'm starting from scratch I would like to know what everyone's using for web based mail. I currently implemented cyrus-imapd and postfix which I used before. I was going to give dovecot a try but it wouldn't start even though it was supposed to be easier. I would like to move my postfix to a chroot but have never done a chroot so I would appreciate any examples. Also how to get spamassassin working or any alternatives. I have the mail server up and can access email with a client so I guess it's up. Thanks, James BTW - I'm running the latest CentOS distro

3.8 update/x86_64 kernel?
by Les Mikesell 28 Aug '06

28 Aug '06

After updating a very old x86_64 3.x install to 3.8 it still has kernel-2.4.21-27.0.2.EL. Then if I repeat the yum update command, it offers to install kernel 2.4.21-47.EL.ia32e. Neither of these situations seems quite right. -- Les Mikesell lesmikesell(a)gmail.com

Does irqbalance actually do anything?
by Steve Snyder 28 Aug '06

28 Aug '06

I've got several SMP machines, some running CentOS 4.3 and some running Fedora Core 4. All machine are kept fully updated. A few are Pentium3-based and a few are Pentium4-based. They are all running the irqbalance daemon. The distribution of interrupts across CPUs is indeed kept balanced, yet even after months of uptime ps shows no CPU use whatsoever by irqbalance. This from a program that is supposed to wake up every 10 (?) seconds and examine the interrupt counts. Given that there is an IRQ balancing scheme in the kernel, I have to wonder if irqbalance is actually being used. The man page for this program consists of a single-sentence description of what the program does. Nice. Does irqbalance really do anything on contemporary Red Hat-based systems? Thanks.

Nvidia card fails with new kernel 2.6.9-42.EL
by Richard E Miles 28 Aug '06

28 Aug '06

I have a NVIDIA 5200 FX graphics card. After reinstalling the nvidia driver for kernel 2.6.9-42-EL and doing a startx command from lvl 3, the x window software issues a failed to get interupt from graphics driver. I tried to reinstall the graphics driver again and got the same results. I changed back to the previous kernel and reinstalled the nvidia driver and the problem went away. I am at wonder why this would happen with a kernel upgrade from centos. -- Richard Miles Federal Way WA. USA registered linux user 46097

Problem with openvpn and tun interface
by Alex Palenschat 28 Aug '06

28 Aug '06

I'm scratching my head here a little. And my post to the openvpn mailing list is not getting any attention. I have an openvpn server working with Windows clients and I thought I'd try to get a client config on a CentOS box running. The client is a minimal install of CentOS and I like to use shorewall (3.2.x). I've tried to run the vpn client with the fw off and on with no change. When I start the client I cannot ping anything on the vpn net or the internal net. As near as I can tell no options are being pushed and the tun interface is not being set up. Running an ifconfig does not show the interface (it does show up on the server). The log is being spammed by this: Aug 28 13:54:06 host openvpn[5196]: TLS Error: Unroutable control packet received from x.x.x.x:1194 (si=3 op=P_CONTROL_V1) Aug 28 13:54:06 host last message repeated 7 times Aug 28 13:54:07 host openvpn[5196]: TLS Error: Unroutable control packet received from x.x.x.x:1194 (si=3 op=P_ACK_V1) I have the same options in my client config as I do on windows except I specified a local address to which to bind. Both boxes are configured with ntp and I've checked that the cert was working as far as openssl is concerned. Does anyone here run this configuration successfully? If so, was there anything you needed to do outside of loading the rpm via yum from rpmforge and setting up the keys/config?
