Issuing a Ping
Ping is a command line program, and must be run from a command shell on the issuing computer. To open a command shell and send a ping, follow the procedure below that applies.
Windows®
1. Repeat the steps you performed above to re-open a command shell.
2. Type “ping” (without quotes) followed by a space and the target IP number, as in the image below – then press Enter.

3. Ping will go to work, and in a moment or two begin reporting results. A ping failure (indicating a network problem) will look like Figure 304. A success ping will display a report like Figure 305.
Apple OS X
For a system running Apple’s OS X® :
1. Double-click Terminal in the Applications\Utilities folder.
2. Type the following command into the Terminal (without quotations) and then add the IP number, and press Enter:
“ping –c 4 ipnumber.”
(So, for example, you might type: ping –c 4 192.168.1.101)
The response will be similar to the Windows® example described above. Again, a ping failure indicates a problem with the network connection.
PULL CONNECTION ISSUES
Note that - if you are Pull streaming from ‘behind’ a router – the IP number shown in the TriCaster’s Location field will only be valid for other systems behind the router. You will need to derive the true external IP address to pass to your viewers (or service provider.)
Again, in this environment you may wish to consider Push streaming with the aid of a Content Delivery Network (a commercial service), as this is generally free of firewall and router woes that often require a friendly system administrator to resolve otherwise.
You will also need to enable “port forwarding” on the router, as discussed next.
