I've set up an nfsv4 server and it's working fine, however the firewall is blocking nfs even if port 2049 and 111 are open.
I know nfs uses some random ports that change at every boot, but how can i make them static so i can use nfs without disabling my firewall again?
I cant for the life of me get x11forwarding to work. I did everything 'by the book'... Both client and server is running ubuntu 11.04. Both have ssh, vnc, x11 and FW ports open
/etc/ssh/ssh_config
ForwardAgent yes
ForwardX11 yes
ForwardX11Trusted yes
/etc/ssh/sshd_config
X11Forwarding yes
X11DisplayOffset 10
apt-get install xauth
xauth is already the newest version.
ssh server -Xvl userecho $DISPLAY return blank
xterm returns xterm Xt error: Can't open display:
xterm: DISPLAY is not set
Still nothing works...
So i did export DISPLAY=localhost:10.0
Then echo $DISPLAY returns localhost:10.0 but xterm returns xterm Xt error: Can't open display: localhost:10.0
Now here's the weird part. if i do export DISPLAY=:0.0 then xterm gives no error, but no GUI is displayed...
Tried everything except reinstalling the OS. Even reinstalled ssh and copied fresh config files from a working install...
Putting here the verbose output:

Any ideas as to how i can correct this, so we can upgrade one ver. at a time (or up to 10.04)
