Configuring the Network Directory
Add Nodes to Network Directory File
Fields Node name The name of the node for which you want network
directory information. The node name field must
contain a fully qualified node name, in the form
nodename.domain.organization, when used to add,
modify, delete, or rename a node.
The node name field when used with the Prev Page
and Next Page function keys allows you to browse
through a specified part of the network directory. You
can enter part of a node name in this field to designate
which node names you want displayed. For example, if
you enter the value NIK, and press the
[Next Page]
function key, the list of nodes will begin with the first
matching node name, for example
NIKOLAI.FINANCE.IND, and continue through the rest
of the alphabet until all node names between the letters
NIK and Z are listed.
Global? The global/local setting for node name. The acceptable
values are Y or N. When the Prev Page and Next Page
function keys are used, only node names whose
global/local setting matches the value in this field are
displayed.
Entries can be configured as either global or local in the
network directory. Global entries (the default) can be
merged into other directories using the MERGEDIR
command. Local entries are not merged into other
network directories. The local entries are used for
configuring localized network directory entries, thus
providing a mechanism to restrict directory data from
being propagated throughout the network.
A situation where this type of restriction could be
useful is when you want to change the configuration for
users on a single host, but not for everyone else. You
can configure two network directory entries: one local,
used by host users, and one global, used by everyone
else when establishing connections to the host. For
example, suppose Node A sets up a new link to Node C,
but Node A does not want other nodes (already
connected to A) to know about Node C until the new
link is tested. Users on Node A can configure a local
entry, which contains information about the new link
not included in the global entry configured for users on
other nodes.
Other uses of local entries include restricting certain
nodes from communicating with the internet, or being
able to direct which way to access remote nodes
depending on your configuration of local entries. When
