Configuring Advanced Server for UNIX Configuring NetBIOS

used_by_wins=

This entry is only important if you plan to run the Advanced Server for UNIX WINS service on a multihomed system, i.e. a system having more than one IP address, since the WINS service must use a unique, well known IP address. Mark the interface you want to be used by the Advanced Server for UNIX WINS service with a line

used_by_wins=yes.

If no interface is marked with a line used_by_wins=yes, NetBIOS will use the first active one for WINS.

ip_addr= , brdcast_addr=, netmask=

The three parameters can be taken directly from the systems IP configuration, they correspond to the output of an ifconfig -i <interface> command (see ifconfig(1M)).

If the keyword “default” is used for any of these parameters, the correct values are read automatically from the system at the time NetBIOS starts. However, the interface must be accessible in UNIX for this purpose (cf. ifconfig <interface>). If this is not true (e.g. in high availibility environments), the keyword “default” cannot be used and the values for the three parameters above must be given explicitly.

If an interface is DOWN in the sense of ifconfig(1M), the corresponding configuration section is loaded but the interface is set to inactive. You can then later use the nbconfig command to activate the interface, see below.

As a general rule, the keyword “default” – which is also inserted automatically at creation time of the interfaces.cfg file – should be used for any of these three parameters whenever possible. This has the advantage that an IP reconfiguration of an interface on the Advanced Server for UNIX computer (e.g. an address change) is transferred automatically to NetBIOS, and thus prevents inconsistent NetBIOS configurations.

brdcast_list=

Normally, broadcast name resolution is carried out in the local subnet only. With AS/X V3.5A20, the keyword “brdcast_list” was introduced to allow name resolution with directed broadcasts: When querying for a certain NetBIOS name, the Advanced Server for UNIX sends name query datagrams (IP level broadcasts) not only to the local subnet, but also to every subnet contained in this list. This method provided an easy way to let name resolution span routers (which normally do not forward broadcasts). Although this feature has several disadvantages, it is still supported for compatibility reasons. The keyword “default” is not allowed with this parameter.
