Shouldn’tthis and this get more news coverage? US Commerce Department computers (specifically a bureau responsible for export licenses) is under cyber attack from hackers based in China. The Bureau in question is the Bureau of Industry and Security…. which handles “U.S. exports which have both commercial and military applications”…. They’ve been targetted by various rootkits […]

NX server and client is a GREAT remote X approach that can tunnel over fairly narrow links well and does phenomenally well over a LAN. I frequently use NX in place of VNC when working with Linux based systems because the performance seems much better and the client has a nice way to choose from […]

Blocking Aggressive Outbound Traffic with IPtables. For starters, I’ve tested this on a test system that started out with NO iptables rules, and then moved on to an IPCop install (the vmware download from vmwarez.com…) I’ve detailed previously one dilemma that I had with regard to my own cable connection which made me question how […]

For Windows system administrators that have sweated over the perils of usb drives and memory sticks…. Intelliadmin has a tool for you. It’s a small utility that will allow to remotely disable usb drives over the LAN. It won’t affect usb mice/keyboards – just usb storage. So, if your network security policy doesn’t like USB […]

So…. what is arp spoofing (poisoning)…. and what are it’s implications? ARP spoofing involves tricking a machine into thinking that you’re machine is, yet another. Let’s put this in IP address terms. Let’s say that 192.168.0.1 is the default gatway on the network and 192.168.0.150 is our target. We are given another network address – […]

A while back I did a network security series and one of the points that I mentioned was that it’s important to know what is normal for your network. In other words, what machines are NORMALLY connected, what services are normally running, etc. Well, I’m about to start a serious look at something that makes […]

I had hoped to do an article on metasploit in the not too distant future, but not as early as tonight…. However, I’ve made a couple of references to it in previous posts which, well, it would be nice if I’d already given a bit of information about metasploit in general. For starters, metasploit is […]

So, now that I was “in” the DWL-800AP+ it was time to see if I could set it up as a repeater. I visited the “wireless” tab of the web based configuration and chose Repeater mode instead of AP mode and saw that I would need the Mac address of the access point that I […]

When you’re not at your home network is probably one of those times you should be more on your guard. Wireless access points are very common and a greatly useful thing, but there are some steps you should take to protect yourself, your pc and the data stored there. First it’s worth having a personal […]

The Hawking Technology Print Server (HPS1P) is a nice little parallel port to ethernet print server that can be configured to make a single printer available to multiple machines on a LAN (local area network). It supports a number of different protocols and can be configured through a web interface, or with a Windows based […]
