Computer Tips -Tech Info

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 […]

There are ways that risks can be avoided. Recently, there was what was called a zero-day exploit for Internet Explorer. As I write this, the exploit surfaced 3 weeks ago and tomorrow there will be a patch. The vulnerability would allow remote code execution through a vulnerability in the way javascript is handled. So, for […]

OK – so as I have mentioned after upgrading to Mandriva 2006 I was looking at the possibility of moving from Evolution to Kontact as the main mail client. I moved contacts and got things massaged quite well. One of the neat features in Kontact is the ability to have multiple address-books/resource names. Anyway, I […]

I REALLY like secure shell (SSH) for remote access to linux machines. You can do more than just a “telnet” like remote shell with it. (Port forwarding.) However, the default configuraton for the openssh-server is sometimes a bit less tight than I would like. For that reason on a new install, I usually like to […]

There’s a joke that many people bring out when new Windows viruses hit big…. it goes along the lines of, “download a fix here” and the link points to a knoppix linux livecd download, or a Mandriva download disk, fedora/etc… Some say linux isn’t affected by as many viruses because it lacks market share, I […]

Once upon a time I did an article about the biggest computer security vulnerability ever. I’ve also passed along the old “the most dangerous part of a car is the nut behind the wheel” joke. If you haven’t got it yet, the computer user can be the “weakest link”. Let’s face it, you’ve got antivirus, […]

I’ve toyed around with the idea of migrating everything over to Kontact for my mail. I’ve used Evolution since moving over to linux, but there are some things about Kontact that just seem slicker to me. While I was doing the install, I had the laptop setup to receive messages through IMAP and used Kontact […]

For those that read this I’d like to wish you all a Merry Christmas and a Happy New Year. I have several posts scheduled to come out each day through the 1st of the New Year, but will likely not be adding to that unless something big happens. I’ll also be taking the week away […]

In the spirit of the day before Christmas, I’ve come across a couple links to help you track Santa Claus’ progress around the world. First up the Google Blog points out that you can track Santa with their Google Earth software. They have a link here that will open in Google Earth –UPDATE Christmas 2006–This […]

I’ve talked about Antivirus software as an essential. Today we’re going to look at Antispyware software. There is a difference. By definition a virus is a piece of software that infects other files or copies itself. A worm is a virus that spreads without user intervention. (From one open network port to another for instance.)
