Installation

1. Download bwbenchX.X.c (replace X.X with the version number)
2. Compile it with: gcc -o bwbench bwbenchX.X.c
3. If you want to install it, copy it into your binary directory, e.g.: cp bwbench /usr/bin
4. You can run it by typing bwbench or (if not installed) ./bwbench. See the usage for details.

Usage

You have to run bwbench as shown here, where host is the host name to connect to and port is the port number:

bwbench host port

To measure the outgoing bandwidth of host A (respectively the incoming bandwidth of host B) first run netcat on host A:

cat /dev/zero | nc -lp some_port

Then connect to the netcat server with bwbench on host B:

bwbench A some_port

bwbench will show you now the incoming bandwidth of host B. Hit CTRL+C to stop.
