Java api to use bpf expressions to filter raw packet data. Tested on Linux and libpcap only but it may work with winpcap in windows.

Tested on RHEL 7

  git clone https://github.com/iryaniv/jbpf.git
  yum install libpcap-devel
  cd ./jbpf/libBpf/
  gcc -shared -o libBpf.so -fPIC libBpf.c -lpcap -I /usr/lib/jvm/java-1.8.0-openjdk/include/ -I /usr/lib/jvm/java-1.8.0 openjdk/include/linux/ -I .
  cp libBpf.so /usr/lib64/

(You should change the java paths to your java installation).

download /out/libBpf.so - compiled on RHEL 7 x86_64 with libpcap-devel 1.5.3

First put the libBpf.so in your java include path. (mine is /usr/lib64/.)
