Computer Tips -Tech Info

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’ve been playing around a bit with podcast clients the last couple of days. I’ve been finding online news feeds for the onlineradiotv.com site and for many of those I have bash scripts to handle downloading or streaming the audio available from shortwave broadcasters. I did run across a few podcasts too though and thought […]

I want to try to clarify a point. I’ve spent a couple days trying to get current exploits to work on a Windows 98 SE virtual machine. Not to prove that Windows 98 is safe, but to determine if current exploits affect Windows 98. Yesterday evening there were apocalyptic headlines saying that virus threatens every […]

So, according to D-Link there is a short list of access points that the DWL-800AP+ will repeat for. They are all d-link branded access points. It seems that there have been firmware updates to improve the compatibility with more models (of d-link access points.) Some of the incompatibilities have been with WEP encryption from what […]

Ok, so now I had to add the new D-Link’s MAC address to the list of authorized MAC’s in the Linksys WAP11 (v. 1.1) For this, I call on wap11gui. Used to (since I use linux), I would have to suffer through a Windows boot on the laptop and balance the laptop on the edge […]

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 […]

Ok – I was thinking I might have been a bit too dismissive of flightgear. So, I took a second look (and a third and fourth.) In fact, I found a source rpm of the 0.99 version and rebuilt it for Mandriva 2006 and installed. And went in search of scenery for the local area. […]

I’ll confess to having a lot to learn about IP ethernet networking. I feel pretty comfortable with basic TCP/IP (v4), the concept of UDP vs. TCP ports, ICMP pings, etc… but ARP is something that I haven’t dabbled much with. It is, of course, a layer that TCP depends on. When a machine sends a […]

Details of a vulnerability in Apple’s Quicktime and iTunes reported at betanews.com. Secunia also has an advisory. It is listed as moderately critical and affects the current version of both quicktime and itunes on Mac or Windows.    Send article as PDF   

OK – the last couple of entries got into some heavy lifting and some real learning on your part. Learning about what software needs to run, what services are running, updating them to keep current on security patches. We even talked about securing services listening for outside connections and limiting them to what is absolutely […]
