LMHOSTS(5) File Formats and Conventions LMHOSTS(5)

NAME

lmhosts - The Samba NetBIOS hosts file

SYNOPSIS

lmhosts is the samba(7) NetBIOS name to IP address mapping file.

DESCRIPTION

This file is part of the samba(7) suite.

lmhosts is the Samba NetBIOS name to IP address mapping file. It is
very similar to the /etc/hosts file format, except that the hostname
component must correspond to the NetBIOS naming format.

FILE FORMAT

It is an ASCII file containing one line for NetBIOS name. The two
fields on each line are separated from each other by white space. Any
entry beginning with '#' is ignored. Each line in the lmhosts file
contains the following information:

+o IP Address - in dotted decimal format.

+o NetBIOS Name - This name format is a maximum fifteen
character host name, with an optional trailing '#'
character followed by the NetBIOS name type as two
hexadecimal digits.

If the trailing '#' is omitted then the given IP address
will be returned for all names that match the given name,
whatever the NetBIOS name type in the lookup.


An example follows:

#
# Sample Samba lmhosts file.
#
192.9.200.1 TESTPC
192.9.200.20 NTSERVER#20
192.9.200.21 SAMBASERVER

Contains three IP to NetBIOS name mappings. The first and third will
be returned for any queries for the names "TESTPC" and "SAMBASERVER"
respectively, whatever the type component of the NetBIOS name
requested.

The second mapping will be returned only when the "0x20" name type
for a name "NTSERVER" is queried. Any other name type will not be
resolved.

The default location of the lmhosts file is in the same directory as
the smb.conf(5) file.

FILES

lmhosts is loaded from the configuration directory. This is usually
/etc/samba or /usr/local/samba/lib.
