.B Example
hosts equiv = /etc/hosts.equiv
.SS interfaces (G)
This option allows you to setup multiple network interfaces, so that
Samba can properly handle browsing on all interfaces.
The option takes a list of ip/netmask pairs. The netmask may either be
a bitmask, or a bitlength.
For example, the following line:
interfaces = 192.168.2.10/24 192.168.3.10/24
would configure two network interfaces with IP addresses 192.168.2.10
and 192.168.3.10. The netmasks of both interfaces would be set to
255.255.255.0.
You could produce an equivalent result by using:
interfaces = 192.168.2.10/255.255.255.0 192.168.3.10/255.255.255.0
if you prefer that format.
If this option is not set then Samba will attempt to find a primary
interface, but won't attempt to configure more than one interface.
.SS invalid users (S)

service. This is really a "paranoid" check to absolutely ensure an

MULTIPLE INTERFACES
===================
Samba now supports machines with multiple network interfaces. If you
have multiple interfaces then you will need to use the "interfaces"
option in smb.conf to configure them. See smb.conf(5) for details.
