Last week, Ken Foster showed us how to use psping on for measuring network latency on Windows - Tip of the Week: Measuring Network Latency. On Linux you can use ping with specific options to achieve similar results.
ping -U -q -c 300 -s 1200 126.96.36.199
The options are as follows:
-U display full user-to-user latency, not just network round trip time.
-q Print only the first line and the summary
-c The number requests to send at one second intervals (300 = 5 minutes worth)
-s The number of bytes sent for each ping
rtt is ‘round trip time’. The values that follow are the minimum, average, and maximum latency values in milliseconds.
