Computer Tips -Tech Info

Sometimes I wish I wasn’t curious about things…. The other night I was working on something on the testbox in the back room and saw the switch lights flickering fairly actively between the server and the internet gateway. At first I thought maybe it was some mail coming in, but it was awfully persistent. So, […]

OK – just fresh off solving the reason I couldn’t get vmplayer to start on my 1Ghz AMD 64 1GB of memory machine…. I started looking at vmserver. (RC1). Now, vmplayer is a free download (so is vmware server). I’m really liking what I see from vmware server and am pretty sure I’m going to […]

I remember the first Windows XP vulnerability was a Upnp vulnerability. I have made one of my first visits on any new XP system a visit to grc.com to disable it on an XP workstation. But, it’s the great thing – makes life so much easier for setting up network devices. “You just don’t like […]

As reported over the last several days, there is a critical problem with RealVNC 4.1.1, there is NOW an exploit in the wild for RealVNC 4.1.1, that SANS is looking for more information on. There are updates from RealVNC for all affected product lines. Other VNC implementations have not been reported to be affected. Only […]

All of the the swarms of trackback spam seemed to last an hour give or take a few minutes, so it does look kind of like “rent-a-bot” activity, lots of different IP addresses, trackback spam sites seem to have a common theme – the last batch was insurance type sites…. a sampling of about three […]

I’ve noticed that the information in Google Sitemaps continues to improve. For instance in the list of search terms and the average top position which is something that previously was quite tedious to figure out (search and then click until you find your page referenced…) It also gives content analysis of your site, and analysis […]

I think it’s time to pass along a long story of what’s gone on over the last week or so here and some of the reasons there hasn’t been anything posted. Generally, I would say that work has been busy, but something happened last week that went a bit beyond the day to day and […]

So, if you haven’t already had enough cause to tighten your wireless security…. we’ve been talking about arp poisoning (spoofing) and the basic conclusion is that IF an attacking machine is on the same subnet as your machine (same IP address range), they can “own” all traffic from you machine to the gateway. It doesn’t […]

So, we’ve spent a couple articles talking about arp spoofing. It sounds really bad, it’s a frighteningly easy way to do a “mitm” or man in the middle attack and anyone using arp spoofing could capture ALL network traffic including passwords. There’s got to be an easy fix right? Um…. well. This is not something […]

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 – […]
