When listing listening sockets using 'ss -nlpe', there is no indication about whether an AF_INET6 socket is dual-stack capable, i.e. allows access from IPv4 as well. The following upstream patch solves this issue: commit f32dc7467fee0b9e55c3fc6e2895d62e881dec55 Author: Phil Sutter <phil> Date: Wed Jun 24 13:07:20 2015 +0200 ss: print value of IPV6_V6ONLY socket option if set If available and set, print 'v6only:1' for AF_INET6 sockets upon request of extended information. For IPv6 sockets bound to in6addr_any, this is the only way to determine if they will also accept IPv4 requests or not. Signed-off-by: Phil Sutter <phil>
