Thanks for the reply Todd. Here's what I found:
Before changing anything:
- There was still no $DISPLAY set on the remote host after logging in. No
change in behavior, X still not forwarding.
After setting a local DISPLAY in my Cygwin ennvironment, I then tried the
follwoing, and it worked, but I did get an xauth data warning:
jnokes AT D-SJC-JNOKES ~
$ ssh -X jnokes AT row-cm
Warning: No xauth data; using fake authentication data for X11 forwarding.
[jnokes AT row-cm jnokes]$ echo $DISPLAY
localhost:10.0
[jnokes AT row-cm jnokes]$
- I ran a test with xeyes and it worked fine.
Thanks for the solution. I'm now intrigued as to why I needed this, never
have in the past, and it alwyas just worked fine. And what is SecureCRT doing
"under-the-hood" to make it work without any visible warnings that Cygwin ssh
is not doing?
Thanks again for the help.
