Programming Fundamentals

Using the LAN to Control the Analyzer

Pinging the Analyzer from Your Computer or Workstation

Verify the communications link between the computer and the analyzer remote file server using the ping utility.

From a UNIX workstation, type:

ping hostname 64 10

where 64 is the packet size, and 10 is the number of packets transmitted.

From a DOS or Windows environment, type:

ping hostname 10

where 10 is the number of echo requests.

Normal Response for UNIX

A normal response to the ping will be a total of 9, 10, or possibly 11 packets received with a minimal average round-trip time. The minimal average will be different from network to network. LAN traffic will cause the round-trip time to vary widely.

Because the number of packets received depends on your network traffic and integrity, the normal number might be different for your network.

Normal Response for DOS or Windows

A normal response to the ping will be a total of 9, 10, or possibly 11 packets received if 10 echo requests were specified.

Because the number of packets received depends on your network traffic and integrity, the normal number might be different for your network.

Error Messages

If error messages appear, then check the command syntax before continuing with the troubleshooting. If the syntax is correct, then resolve the error messages using your network documentation, or by consulting your network administrator.

If an unknown host error message appears, then check that the host name and IP address for your analyzer are correctly entered from the front panel. Press System, Config I/O.

No Response

No packets received indicates no response from a ping.

If there is no response, try typing in the IP address with the ping command, instead of using the hostname. Check that the typed address matches the IP address assigned in the System, Config I/O menu, then check the other addresses in the menu.
