Rowland, as I you mentioned firstly, I have 3 faces: lo, lan, wan.
And you are right, 0.0.0.0 are all IPs.
I need only either listen to lo and lan or lan only, but not wan also.
But in my case and because of 0.0.0.0 are all faces, listening 0.0.0.0
doesn' t equal lo and lan (127.0.0.1 and 192.168.0.254) .
Yes, there is no 22.214.171.124 in netstat list, but 0.0.0.0 should cover and
126.96.36.199 also, or I don' t understand it right.
By the way I examined Samba4 4.1.14 again and 'socket address' parameter is
deprecated by now.
And I can not turn it off to listen to 0.0.0.0 correctly.
I made some tests. In fact there are not 0.0.0.0:137 and 0.0.0.0:138 but
either double 192.168.0.254 or 192.168.0.255 is appeared that make Samba4
working quite not good.
The one and only attempt is don' t include lo to interfaces parameter but
specify 127.0.0.1 to "socket address" . But it needs more checking for me.

I suppose that listening on 0.0.0.0 means that listening on ALL interfaces
including wan one.
But I don' t extremely need it. You understand it, I think.
I can be wrong.
But how can I check it to be completely sure that for 0.0.0.0 is listening
on 127.0.0.1 and on 192.168.0.254 and not on 188.8.131.52 ?

You lose the bet.
Exactly Samba4 listens on 0.0.0.0:137 and 0.0.0.0:138.
If I stop Samba4, these are both sockets are not opened.
You can check it in your own to start netstat while Samba4 runs and when
Or you don' t have pointed out sockets above opened by Samba4, then, please
send config example and Sama4 version you use.
Unfortunatelly there are quite many people, and not in my country only, who
don't go deeper to question essence or don' t want to understand question
completely before put useless words at their posts which are not
corresponded to a topic/posts.
Please read my posts more carefully and put words which are exactly within
topic only, without off-topic discussion, if you want, of course. Ok ?
Shortly, one more: my final purpose is to close 0.0.0.0 from Samba4 without
restriction its functionality on lan or/and lan interfaces or be completely
sure that it doesn' t cover wan IP (interface) , of course, when I don' t
Topic is about Samba4 only, not other soft.
