X forwing + ssh

nightwich — Thu, 19 Jun 2008 09:52:24 GMT

Hi Gurus

I have the following situation.

I upgrade my ssh version and I get some trouble.
When I log-on in to the machine "xpto" the X work fine, but when I log-on from machine "xpto" to another one by ssh I get the error message:

Warning: untrusted X11 forwarding setup failed: xauth key data not generated
Warning: No xauth data; using fake authentication data for X11 forwarding.

Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: MIT-MAGIC-COOKIE-1 data did not match
Error: Can't open display: localhost:10.0

Any ideas what is the problem or how can I solve this problem?

Thanks in advance

Regards

Shalom,

check the DISPLAY variable.

consider using ssh -X hostname

to connect and work properly with GUI apps.

Hey;

Check the ssh_config on xpto: X11 Forwarding is usually turned off by default in the ssh_config.

My ssh_config is in /opt/ssh/etc/ssh_config.

Change

# ForwardX11 no

to

ForwardX11 yes

I usually update the Host* section to the following:
Host *
ForwardAgent yes
ForwardX11 yes
Protocol 2

Hi

I don't have -Y option.

In my sshd_config I have the following options:

ListenAddress 0.0.0.0

AllowTcpForwarding yes
X11Forwarding yes
X11UseLocalhost yes

I already do a intensive search on web but i still have this problem

Any ideas?

ssh -Y hostname "/usr/dt/bin/hpterm -bg DarkGreen -fg white -title "G:HOSTNAME" -e /opt/perf/bin/glance" &
