Statistic
Description
HD Size
The capacity of the unit's storage medium
HD Model
The model number of the unit's storage medium
Chipset
The unit's chipset identifier. (This information may be requested by technical support staff if
the unit malfunctions.)
AES Key
The name and size (number of bits) of the AES key that will be used if a client requests that
data be encrypted before it is transmitted by the Video Gateway to that client. If you have
not modified the default AES, the default key is used, and _DEFAULT_ appears. For
additional information, see
Testing Remote Connections
Ping and Traceroute are tools that send simple messages to an IP address to test the connection between the device
sending the message and the device with the given IP.
Ping sends the message and waits for a reply. If a reply is received, you know the device with the given IP is
running and can receive and transmit data. Using Ping, you can check whether your Video Gateway unit is
running and can be accessed remotely.
Traceroute sends the message and follows the route it takes from machine to machine in the network to reach
its destination. This may help you identify routing problems or firewalls that are interfering with remote
connections to your Video Gateway.
NOTE:
Some devices are configured not to respond to Ping requests. Therefore, the fact that a device does not
respond to a Ping request does not prove unequivocally that the device cannot be accessed remotely.
Similarly, since Traceroute makes use of Ping, the information returned by Traceroute may be
incomplete.
Both Ping and Traceroute are available from any Windows Command Window. You can use them from Windows
to test connections
from the PC
to other devices, such as the Video Gateway. This is useful as an initial diagnostic
tool in a situation in which you can connect to the Video Gateway unit for configuration and client access through a
PC that is on the same LAN as the unit, but you cannot connect to the unit remotely.
You can run also Ping and Traceroute from the Video Gateway configuration utility to test connections
from the
Video Gateway
to other devices, such as SMS / SMTP servers and NTP servers.
Ping
Ping is a tool that sends a simple message to an IP address and waits for a reply. If a reply is received, you know the
device with the given IP is running and can receive and transmit data. Ping is available from any Windows
Command Window. Using Ping from a remote PC, you can check whether your Video Gateway unit is running and
can be accessed remotely. You can also test remote connections from the Video Gateway unit to other devices by
running Ping from the configuration utility.
NOTE:
Some devices are configured not to respond to Ping requests. Therefore, the fact that a device does not
respond to a Ping request does not prove unequivocally that the device cannot be accessed remotely.
To test connections to the Video Gateway unit using Ping from the PC:
1. On the PC, open a Command Window as follows:
Open the
Start
menu and click
Run
. A
Run
window opens.
