I have a stock CentOS 5 system as far as email (sendmail) is concerned that is on our corporate LAN. I am not trying to set up a mail server; I merely want our CentOS systems to be able to send out emails. This works as long as the recipient's domain is our local domain. Any email send to recipients that are not in our local domain get stuck in the queue: # mailq

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

The thread "Problems with kernel-3.10.0-693.5.2.el7.x86_64? reminded me that I have a similar problem but on the latest CentOS 6 kernel I?ve been meaning to report.

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

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

However, I would prefer to use more ?native? Docker commands, as I would rather not have all developers install and configure Singularity when they already have Docker installed on their systems.

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

I'm running the command "yum -y update" from a script called from the the post section of my kickstart config file, and I get the following error: Installing : kernel-2.6.32-71.29.1.el6.i686 185/378 grubby fatal error: unable to find a suitable template After the install, if I log in to the system and remove that RPM and then re-install it with

The company where I work is mostly a Windows shop, but I run a few CentOS servers and desktops.

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

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

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

I've been a big fan of CentOS for a while, and didn't have many issues with CentOS 4.X over the past few years. However, since moving to CentOS 5.1 a few weeks ago, I have received more problem reports from my users than in the last year and a half on CentOS 4.X. I've previously reported the problem with gnome-terminal crashing (and since there is a single gnome-terminal
