From 831e06810a1bc486424f89ee5628fc18f92fd1e4 Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Tue, 1 Feb 2005 06:16:12 +0000 Subject: [PATCH] r5156: started on test driven development of the nbt server. This adds a NBT-REGISTER test that tests that a server correctly defends its name against broadcast name registrations. Jeremy, you might like to look at this. Samba3 nmbd fails to respond.
