I like the idea of a GPL-free OpenSource OS, although I'm running *BSD, Linux (CentOS, Ubuntu, RedHat,) at home. One problem with the GPL is there's very little you can do about having your competitor take your software source and sell it to your customer. Look at CentOS, Whitebox Linux and RedHat. Same code (GPL Linux and RedHat, different vendor and support methods. I love CentOS and find it easier to deal with then RH. The only issue is at work they want to use the "supported vendor" even though they have no support contract from RH.

Sorry, but no. I decided to subscribe to comp.os.vms again after having skipped it for a while, and actually did some catching up instead of just marking everything as read. And while the collection is impressive, it's hardly unique, and no I'm not trying to reduce people, just trying to make people understand that they are not that unique that they might think. If that hurts someones ego, I wish I could say I'm sorry, but the point I was making was that unless someone really presents something on a much larger scale, it's simply not that special. It's a world-spanning network, and someone local to some specific place, who is a local "moron" don't mean that everyone else knows about him. >> They (people like this) exists all over the world, so why should we know >> specifically about Brian? :-) > > You shouldn't.

I have used the DECThreads SSH server and the Fish client. They work fine. The code is almost 10 years old, so they are not uptodate with everything, but they should still be better than telnet ...
