xserver shows apps on the localhost and not on remote client

Hi pals...
I don't know much about X. This having been said, I've got
1) a target host running Xserver and sshd:
ps -ax log says the following:
30198 tty1 S+ 0:00 /bin/sh /usr/X11R7/bin/startx
30222 tty1 S+ 0:00 /usr/X11R7/bin/xinit /root/.xinitrc -- -
mode 0x011B -shadow -mouse /dev/mouse,5
30223 tty1 S< 77:55 X :0 -mode 0x011B -shadow -mouse /dev/mouse,
5
2) a client host connected via ssh with the -X option.
On the server xauth basically doens't have any rule (.Xauthority
doesn't even exist) BUT I disabled the access control (xhost +)
After I've connected to the server, when I try to open a Xapp, I get
this damn message

"Gtk-WARNING **: cannot open display:"

At this point the sole option that seems to affect the behavior is
"export DISPLAY=:0.0".
After I've used it I'm able to start any x application BUT this is
shown in the host target (on the machine I'm connecting TO), not on
the client.
How to solve this ? I've tried a lot of stuff but nothing seems to
work ...

The X server has to run on the machine where you want to see the
application, that is on your *client* above.

The xserver doesn't matter, but the sshd does.

xhost + is unnecessary. Besides, that would have to be issued on the
client machine.

Don't mess with the DISPLAY variable. If ssh isn't setting right, then
there is a problem. Do a ssh login and do this:

echo $DISPLAY

you should get:

localhost:10.0
