Thanks, good info, I'll relay to the amanda list.

Unforch, and this machine has been rebooted by hpfax several times since 
I put all that in /e/sysctl.conf. And a cat of the dozen or so subdirs 
in /proc/sys/net/ipv6 has all the disable-ipv6's set to 1 right now.

Can you explain this? Looks like it worked, but if configure is checking 
that, its not doing as it should. I still see a yes go by when it checks 
for ipv6 connectivity.

And I just had to reboot, the keyboard died, but its been swapped and the 
batteries are brand new. But the mouse is still alive.

I'm stumped.
