When I try to connect to a remote host using Xstart, the following error message displays.'Error: Can't open display: 192.168.1.100:0.0 Error: Couldn't find per display information'

All X client applications should be able to connect to an X server program such as Xmanager. If an X application cannot connect to an X server due to a network configuration problem or firewall installed between them, this error message displays.

If both Unix/Linux machine and PC are assigned with the public IP address and the error message displays, the cause is usually related to the firewall installed on the PC or network. To setup your firewall, please refer to the following FAQ links:

If your PC is located inside a NAT system and assigned with a private IP address while the Unix/Linux machine is located outside, X application cannot connect to the Xmanager running on your PC since the Unix/Linux machine cannot reach to your PC.

Please refer to the following FAQ links to configure your network. You can also try using the SSH protocol instead.

For your information, the private network addresses are as follows:
