        Using -F with no argument will try
        /etc/sslh/sslh.cfg and then /etc/sslh.cfg as
        configuration files. (argument to -F can no longer
        be separated from the option by a space, e.g. must
        be -Ffoo.cfg)

        Call setgroups() before setgid() (fixes potential
        privilege escalation).
