problem: ETHERNET_LINUX: Failed to get interface index -> exit: No such device

[llsshh]

Hello, I sudo the python file "run.py" in the toolchain folder but there is a problem: ETHERNET_LINUX: Failed to get interface index -> exit: No such device. I guess it may be because I haven't chosen a valid interface and port in the file "simulationconfiguration.xml" but I don't know how to choose the valid interface and port. I really need your help and thanks very much for your answer.
