I've spent the morning having fun with the machine that's doomed to be my production server (dual P450, 256MB RAM, SCSI disks RAID 1, blah blah, fun stuff).
Since Ben mentions the ad.tcl file, I thought I'd point out that I've managed to get AOLserver 3 and the latest ACS 3.2 source up and running using ad.tcl and nsd.tcl. Not a .ini file in sight!
I'm also running the latest Postgres snapshot, which is very close to what will be released. So far, works fine.
