AIX

Hello everybody, I'm a new member on this forum.
I have a problem on AIX 6. I can't have an X session from my PC to AIX server on any X progrm (putty,bitwise...).
I've enabled X Forwarding with localhost:0 in putty, I've modified /etc/ssh_config and /etc/sshd_config files.

Code:

AllowAgentForwarding yes
AllowTcpForwarding yes
#GatewayPorts no
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes

But I still have a message:

Code:

MYBKP : / >xclock
X connection to localhost:10.0 broken (explicit kill or server shutdown).

What can I do else?
Thanks for advance

Do you run some Xserver on your PC like Xming?
is so do you try this from root user?

I've installed and run Xming Xserver on my PC. It's OK now.
Thank you a lot
