            Bug ID: 250027
           Summary: ngrep does not work with ipv6 packets
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs@FreeBSD.org
          Reporter: freebsdbugzilla@agneau.org

% uname -a
FreeBSD obelix.bergerie.agneau.org 12.1-RELEASE-p8 FreeBSD 12.1-RELEASE-p8
GENERIC  amd64

ngrep-1.45_3 (from pkg) does not catch ipv6 packets?


To reproduce:
ngrep -d lo0 '' 'host ::1'

and send packets to a local web/smtp/pop/imap  server responding on ::1

Works as expected with ipv4 .

tcpdump works fine with both ipv4 and ipv6
