In your case, set client host to 'localhost':

<client host="localhost" ...

If you have more tsung installed machines, they are connected via ssh. So check connectivity with ssh from the shell.

If you read http://tsung.erlang-projects.org/user_manual/conf-client-server.html and http://tsung.erlang-projects.org/user_manual/faq.html , you'll get useful information.
