Hi all,

I have worked on both CentOS 5.2 and CentOS 5.3. In CentOS 5.2, I could connect to a remote X-server using Xnest binary provided by the package xorg-x11-server-Xnest-1.1.1-48.41.el5 with firewall settings enabled. I enabled the firewall settings from system-config-securitylevel. Now in CentOS 5.3 with firewall settings enabled, I am unable to connect to the remote X-server using Xnest (xorg-x11-server-Xnest-1.1.1-48.52.el5). To successfully connect, I have to either disable firewall settings or filter the TCP ports on which Xnest connects to the remote server. Is there an issue regarding firewall settings in CentOS 5.3 ? I want to connect to the remote X-server without disabling the firewall settings. How is possible ?

Thanks in advance. Siddharth
