How do I access my serial ENET interface using
the hostname?
If you want to use the same hostname that the device is configured with
and you know its IP address, skip to the next step. Otherwise, run the NI
Ethernet Device Configuration utility. (You must use a computer on the
same subnet as the device.) Refer to
Viewing Network Settings for more
information about the NI Ethernet Device Configuration utility.
Verify the device is present on the network by pinging the IP
address of your device.
Ping is a network utility that sends a
packet to a device/host on the network, then waits for it to be
echoed back, which indicates an active device/host. Find the
directory where ping is installed and type in the following
command:
ping IPaddress
where IPaddress is the IP address assigned to your serial device
server. When your device responds to the ping requests, repeat
this procedure, but this time using the hostname:
ping hostname
If your device fails to respond when using the hostname, the DNS
entry for the device is incorrect.
If the network parameters were statically (manually) assigned, the
hostname must be manually entered in your network's Domain
Name Server (DNS) table before you can use the hostname to
communicate with your device. Have your network administrator
enter this information.
You also can manually check that the device's hostname has been
entered in the DNS table by using NSLookup. This network utility
queries the DNS for entries in the DNS table. You can use
NSLookup to determine the hostname associated with any
particular IP address listed in theDNS table. Find the directory
where NSLookup is installed and type in the following command:
nslookup IPaddress
where
IPaddress
is the IP address you want to look up. Alternately,
to determine the IP address associated with a particular hostname,
type in the following command instead:
