About NEWT...


Overview

When you use any Chameleon application, an icon representing the NEWT TCP/IP kernel appears on the screen.  The NEWT application permits you to view information about the current network interfaces.  The NEWT application must be running for network connectivity to be enabled.  It cannot be terminated explicitly, but exits automatically when the last Chameleon application exits.  NEWT provides information through a set of dialog boxes which you can display by choosing the NEWT icon.

Note:	You can minimize the NEWT application with many open dialog boxes and it will minimize all the dialog boxes as well.  When the NEWT application is restored, all dialog boxes reappear as they were prior to being minimized.

Network Tables


Network Statistics

The Statistics menu consists of selections for all network protocol layers (Interface, ARP, IP, ICMP, UDP, TCP and SNMP.

The Interface statistics are displayed for the currently selected interface.  Double-clicking on a particular interface entry also displays the Interface statistics dialog box.

Each menu selection displays a dialog box with statistic values for that protocol.  Each of these dialog boxes can be set to update values every second, by pressing the Start button.  Further updates can be prevented by pressing the Stop button (which appears after you have pressed the Start button).  The Reset button can be used at any time to reset the statistics values to zero for that window.


Network Tables

The Tables menu consists of selections for all network protocol tables (ARP, route, socket, Gateway and DNS, and SNMP).

•	The ARP table displays the current mapping of IP addresses to physical addresses and any defined Frequent Destinations.

•	The Route table displays the current set of route entries corresponding to all local interfaces, static route entries, and the default gateway, if specified.

•	The Socket table displays the currently open sockets, as well as their connections and states.  There is always at least one socket entry used by the NEWT application.

•	The Gateway and DNS table provides a view of the current default gateway, as well as the DNS (Domain Name Server) IP addresses.  The default gateway specifies the machine that will accept and route packets destined for other networks. The IP address of a DNS and up to two alternatives may be specified.

•	The SNMP table provides a view of currently active agents with their corresponding Enterprise ID.  The Enterprise ID is a unique identification number given by the Internet registration to organizations who request an ID for purposes of defining SNMP MIBs.  This is done to ensure the uniqueness of all managed objects for SNMP.  NETMANAGE's Enterprise ID is 233.

This personalized information is now included in the administration portion of the MIB-II in your agent.


snmpd Agents
Agents

SNMP is the Simple Network Management Protocol that allows TCP/IP Managers to manage Agents over the network.

NEWT offers extensible SNMP agents that greatly extend the capabilities of SNMP-based management applications.  SNMP is a standard feature of NEWT and requires no additional base memory space.

Several SNMP agents are provided with NEWT.  All agents start automatically as soon you start a NetManage application.  Agents included are:

DOS

MIBII

SNMP Daemon

Software Distribution and Backup

Workstation

Windows


DOS

The DOS Group is defined under the NetManage Enterprise (=233).

It is defined as Object-Id = Netmanage.3 and includes the following objects:

- Current Drive (OID=Dos.1)

Returns the "Current Drive" in use at your machine, with 1=A, 2=B, etc.

- DOS memory size (OID=Dos.2)

Returns DOS base memory size in K-bytes (typically 640)


MIBII

Groups supported include:

•	System Group

•	UDP Group

Current support is to RFC 1213.  Except the EGP Group and the Transmissions Group.


SNMP Daemon

The SNMP Daemon Group is defined under the NetManage Enterprise (=233). It is defined as Object-Id = NetManage.1. It provides information about the agents that are currently registered with the daemon. Its structure is a table (OID=snmpd.1).

Software Distribution and Backup

The Software Distribution agent allows the network to distribute software, which is sent by a NEWTWatch manager, to the current machine.

The Backup agent is controlled by the NEWTWatch Backup application.  It runs in the background and moves files from the local machine to a server.  When the agent is running, an automated icon appears that shows moving files.
