http://serverfault.com – We have a web server running a PHP application, In order to profiling it we want to use QCachegrind and view the result from a Windows client using Xming Server. The server run on Centos OS 6.2. I have qt 4.6.2 installed from the base repository and I've also installed xorg-x11-xauth openssl using: yum install xorg-x11-xauth openssl. I've configured this in /etc/ssh/sshd_config: X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost yes I've installed Xming Server (Plus the Xming full fonts package) on my laptop (Windows 7) and I'm connecting to the Centos using putty client with Enable X (HowTos)
