Is there an app to measure network throughput? I have IPhome and it will show how much data has been transfered, but it does not show it as a rate, i.e (64Kbps). When viewing streams and optimizing my UPnP server, seeing the actual transfer rate is helpful. It doesn't even have to show a graph.

Well, a script that loops delaying one second and subtracts the total should be trivial. Probably will have substantial jitter though. Coming right up!

Code:

#!/bin/sh
olddata=`/sbin/ifconfig wlan0|awk -F: '/TX bytes/ {print $3}'|cut -f1 -d' '`
while true; do
  sleep 1
  data=`/sbin/ifconfig wlan0|awk -F: '/TX bytes/ {print $3}'|cut -f1 -d' '`
  echo `expr \( $data - $olddata \) / 128` Kib/s
  olddata=$data
done

Why is there no setterm? Grrr...

Ok I copied the script to /usr/bin/rate.sh, changed execute permission, type "usr/bin/rate.sh" and I get: /bin/sh: /usr/bin/rate.sh: not found

What am I missing?

I would normally install it under my home directory, like in /home/user/apps/, thus avoiding permissions issues. You sure it is both readable and executable by all users?
You said you ran "usr/bin/rate.sh", which is missing a / at the beginning. I assume that was a typo when posting, as your error implies that the / was present; but just checking...

weird, I did everything over again at home using WinSCP and it worked. Can't see anything different from the first file except different name.

anyway... the script work great. 20Kbs when streaming MobiTV. There is a lot of jitter, but it's close enough to see the difference between 64K and 24K. Thanks.
