You probably believe at least one of these awesome *nix myths. I love mythology and there's nothing like hearing a technology myth to make my day complete. Just today someone applied one of the following myths in a conversation with me. I didn't say anything but it gave me the idea for this post. Here are the five myths related to *nix systems that I hear most often when dealing with technical and non-technical people alike. You'd be surprised as to how often even the most technical people spout these myths to each other and to the unsuspecting and unknowledgeable bystander. I have to bite my tongue when I hear them. And now that you know them, I hope it ruins your day too when someone slips into mythland with one of these gems.

[Another Ken Hess gem for your enjoyment. - Scott]

Not bad, but what about #3:

Quoting:One of the circumstances where *nix systems could get viruses is where a user has access to a *nix system and other *nix systems on the same network. This user could deploy a computer program that would replicate itself and deliver its payload on all the systems


Maybe I'm getting dim with age, but I don't see how this would work. Unless it was a deliberately malicious act, and the the user had sufficient permissions on multiple systems to install software. Which is quite a bit different than Windows' famous friendliness to malware, where it welcomes any and all stray random executables from anywhere, but won't let the actual human user do anything useful. The typical Windows habit of getting infected from visiting a web site, or from merely downloading an infected email or document, is beyond pitiful.
That sounds like the Morris worm of 1988.
TC --

You can do that on Unix systems if you really want to ---

Let me give you two words: "trust relationship"
Gee whizz, Fred Cohen did a mathematical proof in 1988 that no computer system that shares information is immune from viruses. OK. "*nix" is not immune from viruses.

The real question becomes: Why doesn't the linux-using community suffer from the same pandemic plagues that the Windows-using community does?

That is and has been the interesting virus and malware question. And the "experts" have done and currenctly do their best to ignore it.
@phsolide:

Quoting:Fred Cohen did a mathematical proof in 1988 that no computer system that shares information *with other systems of unknown trust* is immune from viruses.
Fixed.

I can set up an isolated, two-node network that will be the I.T. equivalent of Bubble Boy.
