Configuring Advanced Server for UNIX
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
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.
