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? Thank you
use iptraf

rpmforge provides iperf
And there is a nice Java GUI available: jperf

transfer a file, time it, divide file size in megabytes / seconds to get MB/sec speeds. multiply by 8 or 10 to get approximate backbone speed in megabit/sec. (10 approximates protocol overhead)
Iptraf is a great utility

As in (file_size / transfer_time)? Many transfer applications dumps the transfer rate (wget, etc...).

If you use rsync with the -v option it will show the bytes transferred and the time used at the end of the copy. Note that if the target file already exists, rsync will only transfer differences, though.

scp and wget both give transfer speed information. So using scp to send or receive a large file or using wget to 'suck down' a file via http or ftp will give you a measurment.

Nobody mentioned iftop? That's my personal favorite. Just like top, but now for traffic.
