Indeed I do mean that file. I got Bellovin and Doneland mentally transposed for some reason.

"Class A Data Center"
by Bob German 24 Sep '03

Can anyone point me to a set of standards that define a "Class A Data Center?" I'm not asking for requirements, but an actual pointer to standards hammered out by an organization or governing body. Thanks.

The *.com/robots.txt
by Guy Coslado (GC0111) 24 Sep '03

24 Sep '03

I've found inconsistencies in search engines mainly with domain name having transient status. Such dn inherit a new IP , the *.com IP ( the sitefinder IP). And sitefinder itself has its own inconsistency: Here an example using Nestscape or Mozilla (my IE6 config gives other results). http://www.pallet-containers-unlimited.com/bizdc.html http://sitefinder.verisign.com/lpc?url=pallet-containers-unlimited.com/bizd… That gives a link in Did You Mean ? We did find these similar Web addresses. http://www.pallet-containers-unlimited.com/bizdc.html And now searching with sitefinder http://sitefinder.verisign.com/spc?sb=pallet-containers-unlimited.com&searc… If VeriSign sitefinder doesnt take care of this case, what can we wait with other search engines ? The query : http://www.pallet-containers-unlimited.com/robots.txt gives User-agent: * Disallow: / is also a false answer that can confuse lot of http agents => for simple example, sites with dn in REDEMPTIONPERIOD can be suppressed or blacklisted from search engines indexes for a while. Because nobody knows already all the side effects I'm not sure having a robots.txt here is the best choice. On the other hand SE indexes can keep undefinitively no (more) existent sites without the *.com/robots.txt Possibly the *.com redirect will give us other surprises with search engines.

Anyway, >whats wrong with checking what used to be called "the DNS invariant", >ie. name <-> ip queries should agree as in That seems like it would work as well. In my case I need to make use of the A and MX records for other things anyway, so I might as well go that path. I'd need to sit down and see which mechanism uses the least queries. I'm concerned though that all these mechanisms could fall apart if Verisign decided to start using a third-party content provider to distribute the load on their server. -- Kee Hinckley http://www.messagefire.com/ Next Generation Spam Defense http://commons.somewhere.com/buzz/ Writings on Technology and Society I'm not sure which upsets me more: that people are so unwilling to accept responsibility for their own actions, or that they are so eager to regulate everyone else's.

Appologies to all, and the other DNSbls, I'm a little uptight about how long it is taking for the arrest of the DDoSer. Yes he has been identified, and that's all I can say. / Mat

New CA Law
by Leo Bicknell 24 Sep '03

24 Sep '03

Word is Gray Davis signed this law, http://info.sen.ca.gov/pub/bill/sen/sb_0151-0200/sb_186_bill_20030911_enrol… today. It seems to be a pretty strong anti-spam bill. Given all the talk of black lists and DDOS's and the like does anyone think this will make a difference? Is anyone planning on using the law to recover damages? -- Leo Bicknell - bicknell(a)ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request(a)tmbg.org, www.tmbg.org

More ports to block
by Sean Donelan 24 Sep '03

24 Sep '03

Pop-Up Scam Beats AOL Filter http://www.wired.com/news/technology/0,1282,60564,00.html AOL is not the only Internet service provider currently blocking all port 135 traffic. Many ISPs began filtering the port last month to mitigate the spread of the MSBlaster computer worm, Baldwin said. While AOL also could block UDP ports 1025-1029 to fully eliminate Messenger service spams, the big ISP likely is worried about the potential "collateral damage" such a move might cause to users with legitimate programs that require those port addresses, he said.
