Packet capture

[Richard Braun]

Hello,

I'm currently working on getting libpcap to a decent state on the Hurd.
As already discussed on IRC, permission checking will be performed by
the new devopen translator (devnode in the incubator/dde branch), and
libpcap will include a new Hurd specific capture module. For now, I've
written a (Debian specific) patch that includes a first experimental
version of this module. It currently uses the embedded BPF filter code
in libpcap so that it can be used for both GNU Mach and DDE drivers
(I know GNU Mach supports BPF filters in kernel, not sure about DDE
though, and not sure either it's worth the effort as probably noone
uses the Hurd for any performance critical application; comments are
welcome).

The Debian packages are available at my brand new repository. Add these
to your sources.list file (ftp:// access should also work) :
deb http://ftp.sceen.net/debian-hurd experimental/
deb-src http://ftp.sceen.net/debian-hurd experimental/

For the curious, darnassus.sceen.net is already using the experimental
libpcap0.8 code. Both tcpdump and wireshark were tested with success.

If anyone knows an application that makes use of pcap_inject(), I'd be
happy to hear about it.

Enjoy.
