Computer Tips -Tech Info

As I’ve mentioned I’ve got an ubuntu based test system. Most of my linux experience has been from a red-hat derivitive-based background and for that, at the command line, you have chkconfig which is a good tool for checking the configuration of services to run at startup. It is a red-hat derivitive thing… However, I […]

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 just came across this article about wine-doors which sounds VERY promising. Of course, let me set the stage. Wine is a windows compatibility api for linux. The goal of wine is to allow windows applications to run on top of a linux system without modification (of the original windows version.) There are codeweavers wine […]

One of the big linux news stories yesterday was the release of google earth for linux. Essentially the Google earth team has released “release 4” which is a beta version of the next release. It looks like there are greater “user contribution” capabilities with this release. I’ve tried the download for linux and can say […]

As you might recall some time back I talked about the release of vmplayer which is a free virtual machine “player” from vmware. Mostly, I wrote about the problems I had running it on my main desktop which was running Mandrake 10.1 at the time. The error was basically a signal 11 in the log […]

It sounds like this vulnerability would take a great deal of user interaction, but cio-today is reporting on a browser vulnerability that affects pretty much every javascript enabled browser. According to Symantec …. “This issue is triggered by utilizing JavaScript ‘OnKeyDown’ events to capture and duplicate keystrokes from users,” and is a way that the […]

I saw this yesterday or day before… George Ou has said that Microsoft should move user data to it’s own volume (or partition). He is ABSOLUTELY RIGHT. I think these days the default install for any modern operating system ought to assume you care enough about your data to seperate it from the main OS. […]

I’ve tried to ask myself if I’d trust someone enough to let them run a remote session on my own desktop to solve a problem. I think the answer is “it depends”. If you think about it, I do tech support for home users quite a bit and they let me come into their homes. […]

So, I had the script all ready, I’ve got my x11vnc custom compiled to be as widely compatible as possible, I’ve tested thoroughly on the internal network. The next step was to test my x11vnc “one cut and paste” script over the internet. So, I visited my parents pc which dual-boots Windows XP and Mandrake […]

Well, I’ve got a nice way of doing “easy” one click (or one cut and paste) light desktop support for windows or linux, one uses ultravnc sc, the other uses x11vnc with a special wrapper script. So, what security flaws are there in this process? Well, for starters, I see the biggest vulnerability for the […]
