# addresses.  To control the remote machine you need a hostname for
# ssh to log in.  All the test files must be in the same directory
# local and remote.
# You must have an anchor "regress" for the divert rules in the pf.conf
# of the remote machine.  The kernel of the remote machine gets testet.

# Run make check-setup to see if you got the setup correct.
