Configuring Advanced Server for UNIX Configuring NetBIOS

NetBIOS maintains an internal name table for mapping NetBIOS names to IP addresses. This internal name table contains

●a list of names owned by the local machine

●a name cache consisting of mappings from recently received NetBIOS datagrams (take NBRFCCACHE entries) and

●a list of static mappings from a names.cfg file.

The tuning parameter NBMAXNAMES determines the size of the whole table and NBRFC- CACHE determines the size of the cache. When adapting NBMAXNAMES to large names.cfg files, keep in mind that static name mappings configured in the names.cfg file occupy two or three entries in the name table if default extensions are used.

Setting NBRFCCACHE to 0 disables the name cache. It is recommended not to set NBRFCCACHE to a value less than the default.

NBMAXSESS default: 256, min: 32, max: 2048

NBMAXSESS denotes the maximum number of NetBIOS sessions that can be active at the same time.

NBRFCKALIVE default: 30, min: 0, max: 1440

This parameter controls the “NetBIOS Keep Alive” feature (in minutes).

If set to a value greater than 0, NetBIOS sends periodic transmissions on a session, when no other data is being sent for a period of time. If the other end does not respond to these messages, the session is considered broken after certain TCP/IP timers have expired. By default, NetBIOS sends keep alive messages every 30 minutes.

However, in WANs as well as in dial-up networking environments these periodic messages can cause unwanted effects (e.g. periodic dial-up procedures and/or additional traffic). You can then disable these keep alive messages completely by setting NBRFCKALIVE to 0.

NBRFCDGMTIMEOUT default: 10, min: 1, max: 60

This parameter sets the timeout for lost datagrams. Leave changes of this parameter to your field service support.

NBRFCMAXDGMS default: 32, min: 32, max: 128

This parameter sets the size of the internal NetBIOS datagram table. Leave changes of this parameter to your field service support.

NBRFCMAXFRAGS default: 10, min: 10, max: 64

This parameter sets the size of the internal NetBIOS table that is used for temporarily storing fragmented datagrams. Leave changes of this parameter to your field service support.
