Created attachment 838486 [details] pcap_loop patch ngrep does not display any packets at all when using the libpcap-1.5.0-1.20131108git459712e package from updates. Downgrading to libpcap-1.4 makes it work again. The attached patch, which has been sitting in ngrep git for nearly 6 years, solves the problem for me. See upstream bug: http://sourceforge.net/p/ngrep/bugs/30/
