From e722d7077695242a7d6c0749b9a63741f660382a Mon Sep 17 00:00:00 2001 From: "Christopher R. Hertel" Date: Sat, 4 Oct 1997 01:07:47 +0000 Subject: nmblookup.c: I've added a -r option. When specified, nmblookup will attempt to bind to port 137. In order for this to work, the user must be root and the port must be available (i.e., nmbd not running). If either condition is not met, nmblookup will default to normal behavior; it will try to bind to a free port above 7999. I also removed an artifact. The -p option was being accepted but falling through to the default, which was the usage message. I removed "p:" from the getopt() list. params.c: Rewritten. The scanning is much more linear, and I found and fixed a few bugs. I don't like the way that the scratch buffer is handled, but I believe that it is an improvement over the previous version.
