Yesterday I had a bit of a realization. I had just been looking at a wireless router/firewall setup and was thinking about the firewalling rules (which seemed to be geared at the WIRELESS lan… i.e. blocking that activity on the Wireless segment.) You know, traditionally firewalls have had the attitude of defending the internal network […]

Sans also brings this story about the Debian development server being compromised. Investigation is ongoing. The machine was gluck.debian.org and hosted CVS among other things (ddtp, lintian, people, popcon, planet, ports, release). It has been taken offline currently for a reinstall, other systems have been locked down until they can patch the vulnerability that they […]

Sans has a story on botnet traffic spotted coming from the TOR network. Now, I had to refresh my memory on what TOR is, but it’s an anonymizing network, essentially a computer running TOR, would collect a list of TOR client machines on the internet and then connections to other pcs are routed through encrypted […]

I saw this ZDNet post today with a tantalizing glimpse of Gdrive. It comes originally from cocaman.ch where he found a login page for something called Google Platypus, which is essentially a remotely used file storage. Now, from the page there are a couple of items that can be gleaned. Currently it’s something that’s in […]

and Internet Explorer use has dropped below 80% in the US. Currently 12.93% of online users browse with Firefox. Almost 40% of German web-browsers use Firefox to view the web. It’s nice to see Firefox’s share gaining. I, personally wouldn’t mind seeing SEVERAL competing, standards-compliant browsers with significant share’s. (Opera has moved above 1%.) I […]

I really like printers with their own built in print server. They can be plugged into the network and some operating systems can just find them. Unfortunately most of the time Windows doesn’t just find an IPP printer. One tool that can be handy for such a time as this is a free tool like […]

The great firewall of China may be just an illusion in technical terms. This article describes the details of how things work…. Basically when “banned content” is detected, both ends of the connection are sent a flood of tcp reset packets. Which (if both sides are designed to pay attention to) means that the two […]

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 […]

What follows are some notes taken on vmware server. Most are related to an install on ubuntu-server (NO GUI INSTALLED)…. the main point of this is to have the host system take as FEW resources away from the guests as possible. This requires a few x libraries – but not full blown X gui.    […]

I’ve heard rumors of how the 802.11 pre-n wireless networking hardware really KILLS nearby 802.11 wireless b/g networks. Today George Ou has some details. I really think this is a serious problem with the equipment coming out as it will force people to move to another wireless standard. (Somehow, this is all starting to make […]
