Nbtstat--Notes

The column headings generated by the Nbtstat utility have the following meanings.

Input

Number of bytes received.

Output

Number of bytes sent.

In/Out

Whether the connection is from the computer (outbound) or from another system to the local computer (inbound).

Life

The remaining time that a name table cache entry will live before it is purged.

Local Name

The local NetBIOS name associated with the connection.

Remote Host

The name or IP address associated with the remote computer.

Type

Refers to the type of name. A name can either be a unique name or a group name.

<03>

Each NetBIOS name is 16 characters long. This last byte often has special significance since the same name may be present several times on a computer differing only in the last byte. This notation is simply the last byte converted to hexadecimal. <20> is a space in ASCII for example.

State

The state of NetBIOS connections. The possible states are:

State	Meaning
Connected	The session has been established.
Associated	A connection endpoint has been created and associated with an IP address.
Listening	This endpoint is available for an inbound connection.
Idle	This endpoint has been opened but cannot receive connections.
Connecting	The session is in the connecting phase where the name-to-IP address mapping of the destination is being resolved.
Accepting	An inbound session is currently being accepted and will be connected shortly.
Reconnecting	A session is trying to reconnect if it failed to connect on the first attempt.
Outbound	A session is in the connecting phase where the TCP connection is currently being created.
Inbound	An inbound session is in the connecting phase.
Disconnecting	A session is in the process of disconnecting.
Disconnected	The local computer has issued a disconnect, and it is waiting for confirmation from the remote system.
