ok.. this is getting a bit ridiculous=E2=80=A6 just did a brand new install of the freebsd 9.3 aim on amazon=E2=80=A6 with nothing installed on it and only ssh open i get the same result when scanning with openvas: "Summary: The remote host accepts loose source routed IP packets. The feature was designed for testing purpose. An attacker may use it to circumvent poorly designed IP filtering and exploit another flaw. However, it is not dangerous by itself. Solution: drop source routed packets on this host or on other ingress routers or firewalls.' and by default: # sysctl -a | grep accept_sourceroute net.inet.ip.accept_sourceroute: 0 thing is the other machine - the bsd 10 - was scanned with the sameopen vas setup and with a service called hackerguardian offered by a compony called comodo. they sell that service as a pci compliance scan. both machines are non compliant according to both the openvas scan and the hackerguardian one=E2=80=A6 i can't be done with this job if i can't pass the pci scan=E2=80=A6 i'd appreciate any help=E2=80=A6 thanks... now what?
