And where would you start to look for information?
Right now there are 13 globally spread root-servers which know all the locations of the ccTLD and TLD servers. Without this piece of centralisation it will be hard++ to add new (cc)TLD, because everybody has to update their root.hints (or equivalent) file.
Centralisation an sich is not good, but distributed centralisation is good.
I'm sorry but it is months ago since I've used a floppy. And that was to test out PicoBSD. I would be much more happy to see a bootable cd-rom based thingie, which would allow me to put some bigger stuff on it, like sshd, tcpdump, trafshow, ngrep et al. Despite that it is only a firewall, I need these tools to debug stuff.
On one side of the fence are law enforcement agencies, intellectual property owners and marketers. On the opposite side of the fence are privacy advocates and many consumers and businesses that have registered Web addresses.
And on which site are the network administrators, which use this information trying to keep their network free of unwanted junk (spam, scans, attacks etc) and to alert other people with broken systems?
But virtually all their IP address space is hidden and non-public.
From the public internet yes. But not from other companies they're connecting to.
I have worked for a company which implemented Third Party Gateways *waves to Frank, Guido, Arjen, Andre, Dick et al*: A global cluster of packet filtering firewalls which allowed third parties to connect via a local (as in: the same country) gateway into their network to go to a specified host on the companies intranet.
If this would be implmented with private numbers (10.x, 192.168.x et al), the amount of troubles with regarding of NAT would be colossal (imagine all the proprietary protocols of the ERP systems).
That is why you need globally unique IP address on a system: To have a transparant path from one host to another, no matter where you are, no matter who it is that connects to you.
Life can be hard if you're a 110GHz computer. It wasn't until my 3.168x10E15th clockcycle that there was a movement on the mouse and I had to present a password-requestor on the screen. That might look nice, but I had to wait several million of clockcycles before I got all the needed information from the memory. Memory is sooo slow these days, I recall stories from previous generations that you could have the data the next clockcycle after you had set the address! The downfall started when but right now it's waiting waiting waiting.
Fortunatly the password typed was wrong, so I had the fun of producing a beep for 44 billion clockcycles. It sounds an impressive length of time, but I got bored after about twenty million clockcycli and I changed the tone-height a hertz or two. That'll teach them to make these stupid mistakes!
Yeah... life is as good as you make of it. Hmm... an interrupt. Hold on. Back. Well, 80 clockcycles for that... Stupid optimized code. How much more before we get another timer-interrupt? Aaargh, still more than 80 billion clockcycles...
There are a couple of sites I would am already supporting:
With buying T-Shirts: Userfriendly With buying books (via o'reilly): Perl, PHP, TCL, PostgreSQL and MySQL, BIND. With buying the CDs: FreeBSD.
I know I can find all the stuff I need on the internet, via man-pages et al. But I support them by buying their stuff.
Yes, I would like to pay for Slashdot (just like I pay for my subscription to Wired) and SourceForge (they're providing services for me).
How much? I don't know. Is E 100 per year too much for the services SourceForge is offering? Not really, that's less than I pay for the site which is hosting my domain, my website and which is acting as my mail-relay.
In the past I paid for subscription to BBS's because they offered me services, I paid for shareware (QEdit, 4DOS, X00) because it were things I used everyday: Things on the internet are free as in speech, not free as in beer!
All I want is a simple phone, with a phonebook and a dialtone-setting. I don't need games, I don't need a calendar, I don't need internet on my phone. Just a phone please.
i host a number of different domains. i was using the/etc/aliases file for different users, but that means that sally@foo.com and sally@bar.com are the same person because the aliases file just has the sally part.
Instruct your MTA to use a different alias-file for the MTA related mail and a different alias-file for system-related mail.
So for system-related mail, use/etc/alias which translates root,postmaster,abuse etc to a real user (foo@bar.com).
For MTA related mail, use an alias file which knows that alice@bar.com has to go to alice, but the alice@blaat.com doesn't exist.
I know that PostFix uses the file virtual-agent for it: virtual - Postfix virtual domain mail delivery agent. I assume that Sendmail (and other MTAs) have the same features.
But it's all related to splitting system-related aliases and MTA-related issues!
...is about to replace three Unix servers that run the bulk of its business applications with a cluster of Intel Corp. servers running Linux,...
Why don't they run it on three different piece of hardware with different operating systems to prove that their software works on every system and can coorperate with each other???
That will demonstrate much more than the fact that it runs well on linux...
The directory layout preference algorithm for FFS (dirprefs) has been changed. Rather than scattering directory blocks across a disk, it attempts to group related directory blocks together. Operations traversing large directory hierarchies, such as the FreeBSD Ports tree, have shown marked speedups. This change is transparent and automatic for new directories.
Automaticly for new directories. Better delete the ports collection and reinstall it!
Desqview learned me to do proper programming. It's true. When I used it the first time, all my self-written C programs (and pascal too) bombed because of uninitialized pointer references.
I had to walk through everything to fix it and it learned me how to threat pointers properly. A lesson learned which will never be forgotten:-)
Please please please let them use it wisely.
Let only people who are making certain television programs being able to register there. So startrek.tv for paramount, thesimpsons.tv for fox etc. No cybersquatting, just strict rules.

Treat it like the.museum TLD and it will be an improvement over what we have now instead of yet another way to make money fast for Verisign.
That there sometimes is, or isn't, a release for FreeBSD is confusing.

We would strongly suggest denying all UPNP traffic at your internet borders as there is really no need to allow UPNP traffic across the Internet.
Microsoft Technet:

Block all traffic on port 1600 and 5000.
Doesn't happen often that technet gives more information than a released security alert:-)
It's the network- and the IP layer which drops the packets, they don't mind it it's IP/IPX/Decnet or TCP/ICMP/UDP.
The difference between TCP and UDP is that TCP is session oriented (i.e. the application layer gets the data in a stream instead of per packet and doesn't have to worry about making sure they're in the right order, missing packets et al) and that UDP is not session oriented (i.e. the application layer gets the data in order of arrival, it has to worry about the missing packets, the right sequence).
For the rest, they are treated the same on the network and IP layer, it's only who has the responsibility regarding error-correction and sequencing.
There is a new Linux kernel coming out every 3-4 weeks. These ones are announced too.
If you don't like it, go to the preferences (on the left side of your window) and select BSD under the "Exclude Stories from the Homepage". You're happy, we're happy:-)

If you are interested in playing with IPv6, try to get a tunnel via www.freenet6.net.
They're supporting devices running *BSD, Linux, Win*, Solaris, HP-UX and Cisco IOS.

Google has just announced its first annual programming contest!
Always good to see that these announcements are buzzword and cliche compliant.
You can't count either, 100k + 900k != a billion ;-)
This is what it reads:
Google is providing a selection of about 900,000 web pages in pre-parsed and raw format
That is what you get for the 57Mb or five cd's.
The billion-Web-page store is what your program might be ran on if it wins.
Go to your userpage
Go to homepage
Go to Exclude Stories from the Homepage
Go to sections
Tick BSD
Go to the bottom
Click save
It's not that difficult...

It's all depending on what window-manager you have.
For example, if you're running fvwm/olvwm/twm, you have the fastest and smallest ones you can get.
If you're using Gnome/KDE, you have ones which have more overhead.
UDP drops packets., UDP is unreliable and other stuff...
