I reconfigured the kernel.  Still, there remained problems.

I was getting the message "ae0: transmitter frozen".  I then switched
to a different Ethertalk card.  Then, this problem of freezing went away.

Now, everything seems to work, except that the machine doesn't recognize itself
as an existing node.  Commands to verify self-existence usually fail.

Here is a script run under A/UX.

	Script started on Sun Jan 15 19:39:47 1989
	% ping localhost
	ping: sendto: Network is unreachable
	Killed
	% telnet localhost
(long delay of 1 to 2 minutes)
	Stopped
	% 
	% fg
	telnet localhost
	Trying...
	telnet: connect: Network is unreachable
	telnet> quit
	% ping june
	june.cs.washington.edu is alive
	% exit
	% 
	script done on Sun Jan 15 19:42:19 1989

My guess is that it's a simple matter to fix this.  There is a line
from the /etc/hosts file for localhost:

	127.0.0.1       localhost

Is there anything else that should be in the hosts file?

X11 needs the capability of self rlogin to work, so I need to solve the
loopback bug to run X11.  Hopefully, this the last major bug to
purge in the Etherware.  But getting the new Ethertalk board was a big
breakthrough, since now most everything else works.

Thanks for your (tech) support,
