Hi, could you make sure that you havn't changed any of the following settings of the "nmap.nasl" preferences from the default / empty string:
Max Retries : Host Timeout (ms) : Min RTT Timeout (ms) : Max RTT Timeout (ms) : Initial RTT Timeout (ms) : Ports scanned in parallel (min) Ports scanned in parallel (max) Minimum wait between probes (ms) Maximum wait between probes (ms) As soon as one or more of the above preferences has any data set the "Timing policy :" doesn't apply anymore.
