New Libpcap and Tcpdump Available

Yesterday Libpcap 0.9.3 and Tcpdump 3.9.3 were released at Tcpdump.org. The changelog lists "Support for sending packets" as a new feature. This is the biggest release since 0.8.3/3.8.3 in March last year. I hope to see the FreeBSD ports tree updated to include these new versions, although eventually they will be imported into the base system.

Is allowing tcpdump to send packets a good idea?

richard, can you shed some light on why support for sending packets has been added?

I personally have no need for Libpcap to support packet generation. The WinPcap developers added this functionality a few years ago, and it was on the Ethereal Wish List as "Item 17" back then. I think Libpcap/Tcpdump developer Guy Harris just thought it would be helpful to not have to rely on Libnet.
