Search Again: DOS attacks From: QuickDNS@clube.interlink.com.br Date: Wednesday, December 1, 1999 Time: 10:50:00 pm >Apparently MacOS 9 has better TCP/IP handling. Anyone know if this helps in >DOS attacks? I found some problems in MacOS 9 OpenTransport, but Apple OT BUGs Team sent me an OT implementation, maybe solving this problem! I need to try it yet!! The problem was that Macs with Multihomming was not able to reply correctly requests when the IPs of multihomming was from 2 different classes and computers from each class was not able to have direct contact. So .. some times this Mac with multihomming reply only computers from one class.. some times from the other class... some times no one.. and some times both classes. Really crazy!! ehehehe... >I'm shopping for firewalls for my other two Macs. I'll probably buy a >hardware firewall to cover both. How risky is it to run a DNS server or FMP >server without a firewall? I know many people who don't use a firewall and >have never had a problem (probably because DOS attackers have not found them >yet). I think some upstream ISPs already put you behind some limited firewall >protections. I am ISP Servers Manager and I have a friend here in Brazil that also have a Mac ISP (since 1994, like us). And both us was Mac BBS before ISP. And I never used FireWalls and the same for my friend, in our ISPs. >Any comments and thoughts are appreciated, as well as firewall suggestions! >Thanks! >Eric. Last year he did a challenge! The winner needed to change a HomePage and the prize was an iMac. The Server with MacOS 8.x and WebStar 3 did stay on the Internet for 6 months and nobody won the prize!! Some attacks have been detected! But no one that causes problems to the server. And today he have the idea to make a new challenge, but running servers over MacOS X Server. You could say me.. but in Brazil there are no hackers?! Right? Well... last month in USA there was an anual security challenge and people needed to attack a linux and a NT in 30 minutes. The winner have been a Brazilian... and the rest os competitors have been only crashed the servers. People had use DOS attacks... and others! However, the brazilian had enter the Linux root, destroied some files, than entered the NT and chenged the HomePage in server that was in a BIG Screen in the theater. He wrote: Hallo People... BRAZIL Rul3z !!! Well... last 28/11 a brasilian did incade a website.. in the NASA, take a look: http://www.attrition.org/mirror/attrition/1999/11/28/acquisition.jpl.nasa.go v/ Best Regards, Alberto V. M.
