Obviously, the interviewer wants to know if you have any hands-on skills on UNIX network troubleshooting. If you do have the experience, you must have used the following handy tools:
Netstat – Shows the status of the network.
Ping – Sends packets to a destination address and tracks the performance of packets round trip.
Spray – sends packets (like ping_ but, instead of one packet, it sends a burst of packets for greater duration, putting a simulated load on a network component to better test its communications.
Ifconfig – Can be used to ascertain useful network information as well as to configure the network port.
Etherfind – gives network information about all network traffic passing through the network connection.
