Interesting info, though it confuses me a little.

Where it says:

"It is easiest to just override trusted X11 forwarding by passing -Y to ssh
in place of -X. The -Y does the same thing as -X, but it enables trusted
X11 forwarding for the current connection."

does it mean to say "It is easiest to just override X11 forwarding..."?
Otherwise it seems to be saying you can override trusted X forwarding
with trusted X forwarding.

When it says "OpenSSH 3.8 enables trusted X11 forwarding by default when
connecting to an ssh server that supports trusted X11 forwarding.",
does it mean that overrides the setting in the /etc/ssh_config file?
In other words, which default is the most default?

What happens if your config file has both "ForwardX11 yes" and
"ForwardX11Trusted yes"?  Which is the default then?  Is it bad to have
both?  Is it bad to have one set to yes and the other to no?

Apologies if these are stupid questions.

I notice that I do have openssh 3.8 installed, and also note that the
man page mentions ForwardX11Trusted in only one place, with no
explanation, and the section on X11 and TCP forwarding mentions only
ForwardX11 and the -X and -x options, not the -Y.  So I couldn't get
answers to my questions there.  (This is true in the latest Cygwin, as
of a day or so ago.)
