Hi,
I am using a Mac to remotely log in to my Ubuntu 12 computer.
I have enable X11 forwarding in my Ubuntu machine: In /etc/ssh/sshd_config:
xauth is installed:Code:X11Forwarding yes X11DisplayOffset 10 X11UseLocalHost no
But when ssh -vvv -X user@ubuntumachineCode:$ which xauth /usr/bin/xauth
There is no Requesting X11 forwarding in the debug trace.
And when invoking a gui program like "firefox &", I see "Error: no display specified"Code:... debug1: Authentication succeeded (password). Authenticated to 192.168.1.115 ([192.168.1.115]:22). debug1: channel 0: new [client-session] debug3: ssh_session2_open: channel_new: 0 debug2: channel 0: send open debug1: Requesting no-more-sessions@openssh.com debug1: Entering interactive session. debug2: callback start debug2: client_session2_setup: id 0 debug2: fd 3 setting TCP_NODELAY debug2: channel 0: request pty-req confirm 1 ...
Then I explicitly set the DISPLAY in the client machine before ssh in.
Then ssh -X into the Ubuntu machine again:Code:export DISPLAY=192.168.1.117:0.0 #my mac ip
When entering "firefox &"Code:uthenticated to 192.168.1.115 ([192.168.1.115]:22). debug1: channel 0: new [client-session] debug3: ssh_session2_open: channel_new: 0 debug2: channel 0: send open debug1: Requesting no-more-sessions@openssh.com debug1: Entering interactive session. debug2: callback start debug2: Checking for xauth using xauth -f /var/folders/9s/s5hl5w4x7zjdjkdljw9cnsrm0000gn/T//xauth_test exit > /dev/null 2> /dev/null debug1: No xauth program.

i have the following error:
