Im using the latest Nessus with the latest Nessus linux client. I have problems testing computers that use firewalls. It doesnt find out the ports that are actually open, rather it checks for a quick moment then reports that the host is dead. Is there anyway I can force it to do a complete port scan and report the open ports and test for vulnerabilities instead of this false report that the host is dead. Keep in mind Im using the Linux client and not a Win client so please if you have any ideas refer to the Linux configuration of things.
Thanks.
