Update!!! In poking around with both my Linux box and my Mac, I discovered "man Xsecurity" and thus xhost.
When I executed "xhost +" allowing all my machines access to my Xserver, I was able to get my X-apps
to come up in Apple's X11.
I was also able to ssh into my Linux box with ssh -X user@host, and have Linux X-apps to come up in
Apple's X11 via forwarding.
I don't know why the same doesn't work on my NetBSD box. I guess maybe sshd is broken for Xforwarding???
Any ideas? I would REALLY like to get this to work, so that I can get X-app access to my NetBSD
box when I'm on the road (via ssh.)
