You can set "bindto" to "0:0" to force use IPv4 instead of IPv6. And probably "[0]:0" to force use IPv6, thou this I couldn't test.

Well we can:
set a Context and just read a "file"...
open a socket an read/write to a "file"
no i have a selfsigned cert ( it is in /usr/ssl... ) but after upgrading to 5.6 some Errors came thru.
no i have to downgrad php... so i'm now less secure to be "more" secure ...
