I’ve been experiencing this problem with oidentd for a couple of days and I can’t seem to be able to find a solution to this yet. oidentd seems to give me headaches every time I want to get it work on different servers. I have to mention I’ve installed oidentd using rpm package (oidentd-2.0.8-8.el6.i686 more exactly) because directly typing yum install oidentd didn’t work for some unknown reason. I want to use it in order [...]Continue Reading »

Is says “Choose a Tool” with options for “Authentication configuration”, “Firewall configuration”, “Keyboard configuration”, “Network configuration”. I don’t think it serves a purpose as the VM [...]Continue Reading »
