Load balancing email?
Currently, we have two mail relays for inbound messages, and a third for POP. The inbound messages go thru all the CPU-intensive anti-spam stuff, and then they relay it to the POP server for pickup. Currently, one of these is the "primary", and the other is "secondary", and I'd like them to be considered more or less as equals, since the "primary" system is

Will Firefox 2.X be included/supported in CentOS 5?
I know this mostly depends on what is/will be done upstream, but with the recent announcement that Firefox 1.5.X will only receive updates until April 24, 2007, is Firefox 2.X in CentOS' future? Alfred

Problem getting eth0 up
I'm just starting to test CentOS 6 in our environment, and as a first step did a basic install from DVD (Desktop target, all defaults). Next I will try to automate the installations as I did for CentOS 5 using the anakonda-ks.cfg file generated by the manual install. However, I can't wrap my brain around the new NetworkManager to get it to configure the eth0 interface to obtain an IP

Remote Desktop on CentOS 5.3
Does anyone have remote desktop connectivity working in CentOS 5.3? I'm using the Gnome desktop and have configured the Remote Deskop Preferences to "Allow other users to view your desktop" and "Allow other users to control your desktop". The configuration dialog box says that "Users can view your desktop using this command: vncviewer

Slow CentOS VM when running off the network
I have a CentOS 5.3 VM running under VMware on a WIndows XP laptop. Everything works fine when connected to the network. However, removed from the network, most everything in the CentOS VM takes minutes to complete. For instance, starting a new Terminal window takes over 3 minutes. I did an strace, and there are a couple of long waits when trying to open a socket

Running CentOS on very old hardware
A friend has an old Pentium-133 laptop with 32MB of memory and a 1.3 GB hard disk that he wants to use as a web server for a very small community. Will CentOS (or any other RHEL derived distribution for that matter) install and run with acceptable performance on such a system, or will a specialized distribution like Damn Small Linux be a better choice? In this case, disk space is not a big

Need help resolving yum update issues on mixed architecture system
I have been using 32-bit CentOS since the 4.X days without a real need for 64-bit, but in preparation for CentOS 7, I have installed 64-bit CentOS 6 on a test system to qualify all our builds. However, in order to build some of our current 32-bit applications, I had to install some i686 packages, including glib. Now when I try to do a "yum update" on this test system, I get the dreaded

Yet another yum/rpm update problem
I am in the process of updating a dozen or so workstations from CentOS 4.3 to CentOS 4.4. I set up a local YUM repository, and have been able to successfully update all systems except for one. Both yum and rpm either hang or core dump on this system. I've done a "yum clean all" and an "rpm --rebuilddb" (after deleting the __db files). I was able to

Lingering dhclient issue
I recently reconfigured some CentOS 4.3 systems that were using DHCP to use static IP addresses. At the same time, the systems were moved to a new VLAN. Here is the approximate sequence of events that took place: 1. ifdown eth0 2. edit /etc/sysconfig/network-scripts/ifcfg-eth0 with static IP address 3. wait for network folks to reconfigure switch 4. ifup eth0 I may have

sendmail not sending after reboot
HI folks, I've an up-to-date CentOS 5.x box on a small intranet (<20 users). We did a reboot over the weekend and all appears well except that clients on the LAN can no longer send email. Just hangs/times out. No clear identifiers in the /var/log/maillog or /var/log/messages. We're not setup for ESMTP as it's a closed network and I'm really hoping for a kickstart as to
