Hi All...

So I solved my real problem. It was a typo in my .ssh/config file that prevented me from being able to use the proxy command in ssh. I've used it for years.

But there is still a minor bug in ssh, When I use a proxycommand with ssh with the -W option, to avoid using an external program such as netcat (nc) the error message "getsockname failed: Bad file descriptor" is displayed. The proxycommand works, but displays this error message. Using netcat does not display this error message.

The example above is a STC showing the error in a more easily visible way. The names raven and coyote are local names on my network at home.

I am wishing the error message into the cornfield.

Thanks,

...Karl
