An SSH X11Forwarding problem

[Wang Xu]

Hi list,

I have two Debian Sid box, form A access B with

| ssh -X B

I can open x application (such as xterm or eog...) well.
However, from host B

| ssh -X A

I found there is no DISPLAY environment var, and even
I manually indicated it as "localhost:10.0", just as
from A to B, xterm cannot be started as well (it has
no response until I kill it with Ctrl-C).

Both of them have the most recently openssh (4.3p2-3),
an vith the same configurations (the default configuration
with x11forwarding enabled, as in attachments).

Does anyone have solved the same problem, or any
indication?

Thank you!
