Abstract: Disclosed herein are systems, methods, and apparatus for performing a new kind of traceroute. This traceroute is referred to herein as a “reverse” traceroute, as it enables a given network node to determine the path of packets sent to it from another node. Preferably, an encapsulating tunnel between the two nodes is leveraged. Preferably, a given network node (“first node”) performs the reverse traceroute by sending encapsulated inner packets in the tunnel to another network node (“second node”). The second node reflects the inner packets back to the first node. Preferably, the inner packets are configured such that their IP header TTLs expire at intermediate nodes (such as routers), and such that the resulting error messages are reported to the first node. In this way, the first node obtains information about the topology of the network and the path taken by inbound packets.

Abstract: A hostname based access configuration system (HNACS) is provided for configuring a host-based firewall to implement firewall policies referencing hostnames. The HNACS defines a hostname based firewall policy (HNFP) referencing a host server using a corresponding hostname instead of an internet protocol (IP) address. The HNACS incorporates the HNFP onto the host-based firewall but renders the HNFP non-implementable on the computing device until a domain name system (DNS) query is generated. If the DNS query includes the hostname in the HNFP, the HNACS determines a mapping between the hostname specified in the DNS query and an IP address corresponding to the hostname (obtained via a DNS response corresponding to the DNS query). Based on the mapping, the HNFP is transformed via an implicit replacement of the hostname in the HNFP with the IP address of the host server, thereby rendering the HNFP executable on the host-based firewall.
