# This tests failover capabilities. Data is sent to a local port, where
# no process shall listen. Then it fails over to a second instance, then to
# a file. The second instance is started. So all data should be received
# there and none be logged to the file.
# This builds on the basic sndrcv.sh test, but adds a first, failing,
# location to the conf file.
