This option allows you to override the default network interfaces list that Samba will use for browsing, name registration and other NBT traffic. By default Samba will query the kernel for the list of all active interfaces and use any interfaces except 127.0.0.1 that are broadcast capable. The option takes a list of interface strings. Each string can be in any of the following forms: a network interface name (such as eth0). This may include shell-like wildcards so eth* will match any interface starting with the substring "eth" an IP address. In this case the netmask is determined from the list of interfaces obtained from the kernel an IP/mask pair. a broadcast/mask pair. The "mask" parameters can either be a bit length (such as 24 for a C class network) or a full netmask in dotted decimal form. The "IP" parameters above can either be a full dotted decimal IP address or a hostname which will be looked up via the OS's normal hostname resolution mechanisms. By default Samba enables all active interfaces that are broadcast capable except the loopback adaptor (IP address 127.0.0.1). The example below configures three network interfaces corresponding to the eth0 device and IP addresses 192.168.2.10 and 192.168.3.10. The netmasks of the latter two interfaces would be set to 255.255.255.0. bind interfaces only eth0 192.168.2.10/24 192.168.3.10/255.255.255.0
