Hello Tony!

 There was smething in the back of my mind still nagging, that I had come
 across this as well.

 On all experimental en active versions of Binkd i use:

 listen 0.0.0.0

 So I tried
 listen [ipv6-addres]

 I got the same error as you do. ;((

 I have also something nagging in the back of my mind, that I was looking into
 this, either for binkd or jammnntpd. I think it prooved to be the change in
 name of an element of a structure or the name of a constant.

 The problem is that I currently cannot remember where and how I solved this.
 So I actually wonder if anybody is using the listen option for
 specified IPv6 addresses on a linux system?

 It is clear, that it is somewhere in the call to open a listen socket.

 I will have a look these comming days, but don't hold your breath.
