Error: cannot open display: localhost:0.0 - trying to open Firefox from CentOS 6.2 64bit and display on Win7
I am on a Windows7 machine and I'm trying to get firefox to open on the centOS machine, but be displayed on my current screen.
When typing firefox in terminal, I am getting the following error:
Error: cannot open display: localhost:0.0
To setup the display I used the command
$ export DISPLAY=localhost:0.0
Some site suggested using the following, but it didn't work either:
$ export DISPLAY=:0.0
I am using PuTTY and I have the Enable X11 forwarding check box checked and XMing is running on Windows. Additionally, the sshd_config on centOS file seems to be setup properly as well:
$ cat /etc/ssh/sshd_config |grep -i x11
#X11Forwarding no
X11Forwarding yes
#X11DisplayOffset 10
X11UseLocalhost yes
I've looked over numerous pages and searched StackOverflow as well, but none have managed to help me in any way. Thank you in advance.
Answer
So, it turns out that X11 wasn't actually installed on the centOS. There didn't seem to be any indication anywhere of it not being installed. I did the following command and now firefox opens:
yum groupinstall 'X Window System'
Hope this answer will help others that are confused :)
