please don't forget to cc: the list when replying. you still haven't told me what is staying static. you're using different hard drives. are you saying that all of a sudden, no matter what computer you use, this happens? perhaps an airborne computer virus... you say that the computer is not working. but yet you've replaced every single item. including the hard drive. you installed a fresh version of freebsd on a new drive, and it still crashed. with all other new hardware. do i have that right? -Adam >> (10.06.2002 @ 1830 PST): abe said, in 4.4K: << > replaced the drive almost every other time. it crashes on network activity after ipfw loads > the rules.
