It provides Haskell bindings for most of the libpcap API as of libpcap version 0.9.7. The bindings are divided into a very efficient low-level wrapper, Network.Pcap.Base, and a higher-level module, Network.Pcap, that's easier to use.
To install a stable version from Hackage:
cabal install pcap
To install from the source repo, you may need to generate autoconf related files first. For example:
git clone git://github.com/bos/pcap.git
cd pcap
autoconf -i
autoheader
cabal install
See examples/example.hs for an example of live capturing, dumping
captured packets, reading dumped captures from disk, handling Ctrl-C,
and breaking pcap loops. You can build this example by enabling the
build-the-examples flag. For example:
cabal install -f build-the-examples
Or:
stack install --flag pcap:build-the-examples pcap
Please report bugs via the github issue tracker.
There's also a git mirror:
