Open Transport 2.6 Replaces OT Tuner 1.0 -- Apple Computer has released Open Transport 2.6, which addresses DHCP problems experienced by some Mac OS 9 users and prevents Macintosh computers from potentially being used as traffic amplifiers in certain types of denial-of-service attacks. Open Transport 2.6 replaces OT Tuner 1.0, which Apple released at the end of December as a stop-gap measure. (See "OT Tuner 1.0 Combats Possible Net Abuse of Macs" in TidBITS-511 for details on the potential vulnerability.) Open Transport 2.6 is a 1.1 MB download and only runs on Macintoshes running Mac OS 9, or on Power Macintosh G4s, iBooks, and slot-loading iMacs (like the iMac DVs) running Mac OS 8.6. Open Transport 2.6 is also available via Mac OS 9's Software Update control panel, so if you have your Macintosh configured to install software updates from Apple automatically, you may get Open Transport 2.6 automatically.
