Network Diagnosis Using a PC
While this section documents the diagnosis process using a Windows based PC, similar
diagnostics can be performed on a Macintosh or Unix/Linux/OSX system. The system
that is going to be used for testing should be connected to the same VLAN that the
MBOX is connected to. The network configuration should already be documented in the
table under “Document the Network Configuration of the MBOX” on page 31.
Open a command line window to execute on the following steps:
Enter the command
“
nslookup mbox2.trusonic.com
”
which should return an
address of:
206.173.28.19
Enter the command
“
nslookup mbox2.trusonic.com ns1.trusonic.com
”
which
should return an address of:
206.173.28.19
If the prior nslookup commands are successful, enter the command
“
telnet
mbox2.trusonic.com 80
”
and note whether the connection was successful or
not.
A failed connection will result in a message similar to “
Could not open
connection to the host, on port 80: Connect failed
”.
If this command is not successful,
please review your network topology and hardware
configurations between the MBOX and the Internet and set them to allow traffic over
port 80.
A successful connection will simply blank the DOS command window.
To exit the telnet
connection type
“
GET /
”
and press
enter
.
You’ll get some cryptic HTML output
which is exactly what you are supposed to see.
