Hi John, You might want to check out www.opencalea.org. We have just released opencalea-lite which is a complete re-write of the original opencalea software. OpenCalea-lite is a much better and cleaner re-write(we learnt from our mistakes in the previous releases). One of the problems of the original version was that we were getting bogged down in details over the precise standard format instead of making the core more stable. OpenCalea-lite takes a step back form this and aims at doing well the essense of what packet taps should be able to. It has a nice clean tap/controller/collector architecture which is much more robust. Taps will register with the controller irrespective of which is started first. Process control has also been improved. Starting and stopping taps is handled in a much cleaner way. In addtion TCP streams are used to transfer data. We were about to send out an announcement regarding opencalea-lite on the opencalea () merit edu mailing list. Aside from calea requirements opencalea-lite is actually a fairly good platform for running remote-taps in your network. -manish

Our bandwidth is currently pretty low butI've got 8 links to tap, which means I need 16 ports. Has anyone done anyresearch on doing accurate packet capture with commodity hardware? -- John A.
