Weekly Report -- 04/11/2011




Started looking into the traffic sent to "sleeper" hosts, i.e. IP addresses that have been active but are now inactive. Still putting together the initial results, but there is definitely a difference between the traffic observed heading to "dark" hosts vs the traffic observed heading to sleepers.

During the sleeper analysis, I've been able to improve a few of the libprotoident rules to correctly match more of the traffic I've been looking at.

Began integrating Simon's OSPF parsing code into libtrace. Been slightly trickier than I had anticipated due to major differences between OSPFv2 (which Simon's code parses) and OSPFv3 (which we may want to parse in future).

Had a brief phone meeting with Vineyard Networks. They've agreed to give us access to their NAVL library for evaluation.
