Fix error message on UI when testing Opossum

Browse Source 
As `wait_kill()` returns with 0 when a TCP reset is encountered
and the process is not killed, we need to open the socket again
in a sub shell. Which is safe in the foreground.

If then the subshell returns with 0 we can safely connect to
port 80.
