x11 configuration

I'm not really sure what I'm doing, but I have tried many permutations of the x11 settings that people recommend setting.

my linode is a fresh debian 6 install +

apt-get install eclipse

apt-get install xorg

apt-get install xauth

apt-get install x11-apps

$> echo $DISPLAY

localhost:10.0

$> less /etc/ssh/sshd_config

…

X11Forwarding yes

X11DisplayOffset 10

X11UseLocalhost yes

PrintMotd no

PrintLastLog yes

TCPKeepAlive yes

…

Client side, I have installed xming, on mouseover it reads

Xming Server:0.0

and my putty settings are default except

Connection>SSH>X11:

enable x11 forwarding: checked

X display location: 0:0

$> xeyes

Error: Can't open display: localhost:10.0

$>

I sort of suspect the problem is in not initializing something something xauth. But I'm a total noob.

help is (obviously) appreciated greatly!
