PikeFlows: Pike IP packet flow analysis

Around the end of last year I wrote a IP and IPv6 flow handler in Pike for some packet analysis I wanted to do.

The code is available here under the GNU LGPL.

It's simple to use, and there is a demonstration app which simply keeps track of all your flows and periodically prints out all your active connections:

Just take a look at flow.pike in the archive. The important part being void capture_cb(). It takes the packet from libpcap and explodes it with the Ethernet.Frame module, it then takes a look at the frame type. It passes IP packets to either IP.v4.Packet or IP.v6.Packet and then on IP.Flow.Engine for processing into a flow. Something I threw in to show how easy it is to work with is de-encapsulation of 6to4 packets from within IPv4 packets.

I should write some documentation, but in the mean time just email me if you have questions. Thanks to Bill for Public.Network.Pcap.

Mikado 2009 Flyer Released

The Mikado 2009 product announcement flyer is out, and this one contains some interesting information - for example the new Mini V-Bar, pictured on the right is the entire V-Bar unit, the three-axis accelerometer built into one unit - if that's not enough you can plug two Spektrum satellite receivers directly into the unit and not have to use a master receiver!

On top of that they have announced that version 4 of the software is a drastic improvement over the old 3.6 version including pre-configured setups for various well known helicopters (Logo, T-Rex, etc) and an "auto-learn function for trimming values and parameters".

On top of that they have, in a somewhat strange move announced a new Logo 500 Special Edition, which has a longer boom to accommodate up to 600mm blades. A painted fiber-glass canopy and white skids. This all sounds really good until you think "hang on, don't we already have a Logo 600?". I'm not sure what this is supposed to achieve except perhaps phasing out the Logo 600dx, which always seemed like a doomed product to me.

Regardless, I'm looking forwards to these products hitting the markets (and especially the new vstabi software, which I am most easily able to sample for myself) and hear what people think of them. No doubt, I'll keep you informed.
