Hi, I have three arch 0.6 installs. 2 at home and one at work. My problem is that I cannot open a display on my work machine from home. The installs are identical, all done in the last 3 days. On all 3 machines I have changed /etc/sshd_config 'X11Forwarding yes' and in the ~/.ssh/config set ForwardX11 yes' and 'ForwardX11Trusted yes'. The home machines are behind a hardware NAT router attached to a cable modem. No software firewall options. I can launch windows between the home machines and also at other computers at work from the home machines, but when i try to launch something using an ssh terminal to the work arch install from home, i get 'Can't open display'. The display variable is set, but it just does not work. I have tried things like 'xhost +' on the home machine prior to ssh ing to work, also playing around with /etc/X11/xdm/xdm-config settings at home. I don't think that this could be it, as there is no problem between home computers. Any ideas?
One think I found while searching is a possible problem with the available fonts, but this does not seem possible as the installs are identical. I have used 'pacman -S kde' to install the desktops. I did not do anything specific with fonts.
Previous linux installs at home have worked, except for a xandros 2.0 install that I had problems (can't open display) also.
I had made a typo in my hosts file. I had this (my hostname is very original):
rather than the loopback:
Now things are fine. I am surprised that not being able to tunnel remote windows was the only symptom.
