why the test failed?

[bigapple]

Hi,
I installed PTS4.0 succeed.
I try to run the test (pts/network-loopback), but it is failed.

output infomation :

Loopback TCP Network Performance:
pts/network-loopback-1.0.0
Test 1 of 1
Estimated Trial Run Count: 3
Estimated Time To Completion: 13 Minutes
Started Run 1 @ 17:19:56
The test exited with a non-zero exit status.
Started Run 2 @ 17:20:02
The test exited with a non-zero exit status.
Started Run 3 @ 17:20:04
The test exited with a non-zero exit status.

Test Results:

This test failed to run properly.

The following tests failed to properly run:

- pts/network-loopback-1.0.0: Time To Transfer 10GB Via Loopback

How should I do?
thanks a lot!

check if you have loopback interface (127.0.0.1 or ip6 variant) via ifconfig and have at least network card installed.
