Dear All I have one centos server equipped with WiFi . I want to measure data rate speed on this connection . Is there any utility on my centos that can measure data speed on one specific Ethernet connection when transferring large size files through WiFi connection?

(10 approximates protocol overhead)

Many transfer applications dumps the transfer rate (wget, etc...). JD

Note that if the target file already exists, rsync will only transfer differences, though. -- Les Mikesell lesmikesell at gmail.com

That's my personal favorite. Just like top, but now for traffic. Theo
