speedometer [options] tap [[-c] tap] ...
Monitor network traffic or speed/progress of a file transfer. At least one tap option (-f, -rx, -tx) must be entered. Option -c starts a new column, otherwise taps are piled vertically. Note: before you use the program, satrt generating traffic by transferring files in/out e.g. with scp(1) in the network you're measuring.
-b Use old blocky display instead of smoothed display even when UTF-8 encoding is detected. -f filename [size] Display download speed with progress bar. This option must be used if directly following another file tap without an expected size specified. -i interval Interval in seconds. Examples: 5 or 0.25". Default is 1. -p Use plain-text display (one tap only). -rx iface Display bytes received on network interface. -tx iface Display bytes transmitted on network interface. -z Report zero size on files that don't exist instead of waiting for them to be created EXAMPLES How long it will take for my 38MB transfer to finish? speedometer favorite_episode.rm $(( 38 * 1024 * 1024 )) How quickly is another transfer going? speedometer dl/big.avi How fast is this LAN? host-a$ cat /dev/zero | nc -l -p 12345 host-b$ nc host-a 12345 > /dev/null host-b$ speedometer -rx eth0 How fast is the upstream on this ADSL line? speedometer -tx ppp0 How fast can I write data to my filesystem?
