Sometimes you know you need a package, but when you try to install it with yum you’ll get a message like “No matches found”. Yet you’re sure the package exists because you’ve used it before. This can happen if the package in question is part of a set which installs multiple packages. The net-tools package … Read more
I like developing and testing websites on my local network before they go live. On both Mac and PC it’s easy to tweak the /etc/hosts file so that the URL doesn’t point to a numeric IP, but instead to http://yourserver (or something equally catchy).

I was researching auto login options for CentOS today. I thought those would come in handy when GNOME is used as a standard desktop, so that the computer starts straight into the desktop environment without the need to provide a password.

There’s always some switch I forget and ultimately something isn’t working. For years I was thinking, “there has to be an easier way, like there is in Plesk”? … Read more

Dovecot does more or less the same as Courier (i.e. lets you receive mail), but it’s a bit more configurable and debug friendly. It also offers … Read more

It just occurred to me that even though I know my way around vi fairly well, I never had to quit it without saving my changes. Usually I just go back in and overwrite my mistakes. Today I did something though that wasn’t as easy to eliminate: instead of pasting an IP address, I accidentally … Read more
SELinux – when installed – can take on one of three modes: To check which mode SELinux is running on, we can use either sestatus for a more detailed output, or simply getenforce for a one liner: sestatus SELinux status: enabled SELinuxfs mount: /sys/fs/selinux SELinux root directory: /etc/selinux Loaded policy name: targeted Current mode: enforcing … Read more
