Great article at HowToForge on setting up KVM on a CentOS 6.0 host server.
A good article on setting up a FreeRADIUS server for authenticating WiFI users, this is a good thing to do at home if you have a spare server or run a VM server, and all small businesses should be doing this.

This program provides a method of sending Windows Eventlog events to a syslog server. It works with the new Windows Events service found in Vista and Server 2008 and can be compiled for both 32 and 64-bit environments. Designed to keep up with very busy servers, it is fast, light, and efficient. The program is designed to run as a windows service.

PwnedList is a tool that allows an average person to check if their online accounts have been compromised. The site started out as small research project with a rather simple premise. To discover how many compromised accounts can be harvested programatically in just a couple of hours. Well, needless to say, the results were astonishing. In just under 2 hours we had close to 30,000 accounts, complete with logins and passwords. The truly scary part, however, was the quality of data we were able to collect in such a short amount of time. The accounts we were able to retrieve consisted of email services, social media sites, merchants and even financial institutions. It was clear that something had to be done.

An interesting article at Admin-Magazine about using Apache Bench as a DoS tool and some mitigation recommendations.
Unfortunately VMWare removed the great little Host Update utility for the FREE version of ESXi 5 (vSphere 5). So we now need to use the vMA 5.0 vm from another ESXi host or you can use the vCLI – we will use the vMA 5.0 from another ESXi host. Download vMA 5.0 from http://www.vmware.com/support/developer/vima/ and install and configure this VM on another VM host or some other form of host i.e. VM workstation and so forth.
Now use the VMWare Patches Portal to find your updates/patches:
We will update the FREE ESXi 5 VM host to build 474610 with ESXi500-201109001.zip that we downloaded from the portal.
Upgrade steps (assuming your vMA is up and running and you can connect to your ESXi hosts):
- Place the host to be patched into maintenance mode. Do this with the vSphere client.
- Upload the ESXi500-201109001.zip patch file package to a datastore on the VM host to be patched, in my case the datastore name is DataStore1
From the vMA machine verify which VIBs are already installed on the VM host with:
esxcli --server=192.168.16.20 --username=root software sources vib list --depot=/vmfs/volumes/DataStore1/ESXi500-201109001.zip | more
- Now update the VM host with:
esxcli --server=192.168.16.20 --username=root software vib update --depot=/vmfs/volumes/DataStore1/ESXi500-201109001.zip
- Once the update has completed, reboot the VM host and you should see it’s been updated to build 474610 or whatever update build number you are going to.
