Hi all, I've googled for more than a week trying to
fix this SSH X11 tuneling problem.
I appreciate some help and thank you in advance.
I have a remote Solaris 9 with the following options in /etc/ssh/sshd_config:
X11Forwarding yes
X11DisplayOffset 10
ForwardX11Trusted yes
Then I ssh it from my local desktop: (only most important lines here)
[localdesktop]% ssh -vvv -XY user@remoteserver
OpenSSH_4.2p1 FreeBSD-20050903, OpenSSL 0.9.7e-p1 25 Oct 2004

debug2: callback done
debug2: channel 0: open confirm rwindow 0 rmax 32768
debug2: channel 0: rcvd adjust 131072
Now in the remoteserver:
user@remoteserver % echo $DISPLAY
DISPLAY: Undefined variable
user@remoteserver % netstat -a
remoteserver.ssh localdesktop.51899 66608 47 66608 0
ESTABLISHED
Even if i setenv DISPLAY to localhost:10, 11, 12 ... it does not work.
And from this netstat output I cannot find the X11 tuneling channel.
In another attempt below I have the following different debug messages:
[localdesktop]% ssh -vvv -o "ForwardX11Trusted no" user@remoteserver
debug2: x11_get_proto: /usr/X11R6/bin/xauth -f /tmp/ssh-9xszkw26hB/xauthfile
generate :0.0 MIT-MAGIC-COOKIE-1 untrusted timeout 1200 2>/dev/null
debug2: x11_get_proto: /usr/X11R6/bin/xauth -f /tmp/ssh-9xszkw26hB/xauthfile
list :0.0 . 2>/dev/null
debug1: Requesting X11 forwarding with authentication spoofing.
debug2: channel 0: request x11-req confirm 0
and again DISPLAY is an undefined variable.
Could anyone help me to get this X11 tunelling work?
Thanks all very much,
nader
