If two lines are cut by a transversal and the alternate exterior angles are congruent, the lines are parallel. Interiors on Same Side Converse. If two lines are cut by a transversal and the interior angles on the same side of the transversal are supplementary, the lines are parallel.
The open port checker is a tool you can use to check your external IP address and detect open ports on your connection. This tool is useful for finding out if your port forwarding is setup correctly or if your server applications are being blocked by a firewall.
Step 8: Test the connection. Move over to a machine that can display graphics (if your server does, you can test from there) and fire up your VNC client of choice and attempt to log in with the IP address of the server and port 5801. You can actually test this with a browser (if Java is installed on the machine). To do this, open up the browser and go to http://ADDRESS_OF_VNC_SERVER:5801. That address should open up a VNC session in your browser. If, on the off chance, it does not... try the address http://ADDRESS_OF_VNC_SERVER:1.
