The Samba-Bugzilla – Bug 11718
Config: interfaces = DNS name only binds to one IP address
Last modified: 2016-02-05 15:19:33 UTC
bind interfaces only = yes
interfaces = localhost
Assume that, DNS Record localhost has to 2 IP addresses (127.0.0.1, ::1), which both have network interfaces on the computer.
Samba binds only to one of them and not to both.
This applies for all other DNS Names which have multiple records.
