Come on jim, you can always run MacDNS 1.0.4 right? Then do an applescript to change it for you. Sorry everyone I couldnt resist being a another MacOS user. I think jim also bought a new iMac... Dave At 3:25 PM -0000 9/16/98, James R. Cutler wrote:
As long as one is interested in DNS zone SOA record serial numbers, it is convenient to use the following script to simplify the user interface and view. Of course, this assumes an operating system with a shell. I would love a translation to perl so I could run it on my MacOS machine. :)
