  1. What about security??? by Anonymous Coward · · Score: 4, Interesting

    I'm appalled that he considers IP address matching to be a way of preventing abuse. Sure, his cable modem is a separate interface so he can use a firewall to block it. But what if you're on a large untrusted LAN and you want to share files between two machines? I have exactly this problem (I have a laptop and a desktop at university) and I'm still looking for a simple yet secure way to share between them without allowing anyone to just spoof the IP address (and preferrably without transmitting my secret plans for world domination over the wire in the clear).

    Try that for 3000 clients and your performance is toast !

    1. Cluster your export points
    2. Use hardware accelerated encryption devices
    3. Ask yourself: do these 3000 clients really need access? And what part of the local file system do they need access to? I realize that querying 3000 users for their purposes is a bloody hard job now, but it should have been done in the first place. Follow the principle of least privilege.

    For an organization with 3000 external clients, security shoult be at the top of the TODO-list. Finding a hacker/spoofer among 3000 clients is like finding a needle in a haystack. If this scenario is yours, then please reconsider some major security face lifts...

    Um, because it is gaining market share?

    Apple, in their last quarter report, announced the sale of one million boxes of OS X (a *BSD OS) and two million systems with it on the hard drive.

    The new iMac, booting OS X by default, had 150,000 preorders.

    The new iMac is the top selling computer for all time at Amazon. It is outselling every XP PC on Amazon.

    Out of the top 25 bestselling computers on Amazon, 10 were Macs, and all Macs are now shipping OS X as the default booting OS.

    ZDNet ran this (http://techupdate.zdnet.com/techupdate/stories/ma in/0,14179,2659085,00.html) article about how the number of *BSD users will soon exceed the number of Linux users, largely thanks to OS X and Darwin. *BSD already has three times the number of Linux desktop users. (And if the Linux users aren't happy about this, they can just run out and make more Linux users and make Linux more successful on the desktop. Then we can have a fun race with them. ;)

    Sorry to burst your tragic bubble (not really ;) but *BSD is currently in no danger of death.

    *BSD is in serious danger of growth!

    Oh, there is a doomed OS alright. It is an evil empire, built on a foundation that now crumbles and groans under its weight. This empire doesn't see the danger. It never will, until it is too late. A hero thrice thought dead (Apple, Next, *BSD), now reborn, arises to shatter its foundations.
