Why running 2 pings at a time

Ronja electronics could have a fault causing crosstalk between the directions which would cause packetloss that would happen only if both directions are loaded simultaneously. We excersise this condition by running two instances of ronjaping simultaneously.

Running Ronjaping

Run two instances of ronjaping simultaneously in different xterms or consoles. Replace <other side> with IP address or hostname. 

ronjaping -c -l 1472 <other side>
Leave it running long enough. The lower the expected BER is the longer you have to run it.

Read the BER

Press ctrl-c in the instance started later. ronjaping prints out the BER. The precision depends on how long it has been running.
