If you need a good, reliable name server, use Linux.

The Linux named seems to be very solid, and has all of the same bells and whistles as BSD Unix. If you need to put it on the radio, then you could try the kernel patches for AX.25 or even link the Linux box to a KA9Q machine with Ethernet. -- Mike P.S. We found a bug in the 1.1.39 Linux beta kernel that affects DNS. If you are a primary authoritative server from which secondary authoritative servers attempt to do zone refresh, the zone refresh fails. We don't know why, but the current release kernel, 1.0.9, works fine. ------------------------------ Date: Mon, 08 Aug 1994 17:33:09 -0400 From: "Brandon S.
