But I guess you could see it the other way round. I'm getting myself a little confused here; this is what happens: If I do: Gentoo ssh -X debian "xterm" it fails. The error message changes with diffent options set but generally it cannot open a display on localhost Now the other way round: debian ssh -X gentoo "xterm" works fine > Before you try connecting to it from the gentoo machine?

Doing `xhost +' on debian before ssh -x from gentoo does not help a bit. Apparently as others have indicated it is a long standing gentoo problem. But since -Y works... well I'm about ready to go on about my business and ignore the failure of -X.
