Displaying the server information table (track)

Applications need to know about the services available on a network and the address through which their services can be accessed. SAP agents maintain this information in the server information table. It provides clients with the addresses of all the servers on the internetwork. For more information about the server information table, see ``Service advertising''.

track can monitor the current state of the server information table. The NetWare SAP Monitor and showsvcs can list selected information from the server information table that you can use to monitor and validate the network names, addresses, and services offered by servers on the network.

To display the information currently in the server information table, run track with the command line:

track tables

track writes the contents of the server information table to /etc/ipx.d/sapd.out.

The output from track looks like this:

Type

Novell object type of the service being advertised. For example, 9E advertises an NVT server, 4 advertises a Novell file server. For more information on Novell object types, see Table 4-5.

Hops

The first hop value indicates the number of hops to the advertised server. The second hop value indicates the number of hops to the machine that was the source of the hops information.

Address

IPX address of the advertised server. The first number is the network number. The second number is the node number. The third number is the socket number.

Timer

Time in ticks to reach the advertised server

connectedLan

Address of the connected LAN segment

Network Access Protection Design Guide

Updated: October 6, 2008

Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista

Network Access Protection (NAP) is one of the most anticipated features of the Windows Server� 2008 operating system. NAP is a new platform that allows network administrators to define specific levels of network access based on a client�s identity, the groups to which the client belongs, and the degree to which the client complies with corporate governance policy. If a client is not compliant, NAP provides a mechanism for automatically bringing the client into compliance (a process known as remediation) and then dynamically increasing its level of network access. NAP is supported by Windows Server 2008 R2, Windows Server 2008, Windows 7, Windows Vista�, and Windows� XP with Service Pack 3 (SP3). NAP includes an application programming interface that developers and vendors can use to integrate their products and leverage this health state validation, access enforcement, and ongoing compliance evaluation. For more information about the NAP API, see Network Access Protection (http://go.microsoft.com/fwlink/?LinkId=128423).

The following are key NAP concepts:

NAP Agent. A service included with Windows Server 2008, Windows Vista, and Windows XP with SP3 that collects and manages health information for NAP client computers.
NAP client computer. A computer that has the NAP Agent service installed and running, and is providing its health status to NAP server computers.
NAP-capable computer. A computer that has the NAP Agent service installed and running and is capable of providing its health status to NAP server computers. NAP-capable computers include computers running Windows Server 2008, Windows Vista, and Windows XP with SP3.
Non-NAP-capable computer. A computer that cannot provide its health status to NAP server components. A computer that has NAP agent installed but not running is also considered non-NAP-capable.
Compliant computer. A computer that meets the NAP health requirements that you have defined for your network. Only NAP client computers can be compliant.
Noncompliant computer. A computer that does not meet the NAP health requirements that you have defined for your network. Only NAP client computers can be noncompliant.
Health status. Information about a NAP client computer that NAP uses to allow or restrict access to a network. Health is defined by a client computer's configuration state. Some common measurements of health include the operational status of Windows Firewall, the update status of antivirus signatures, and the installation status of security updates. A NAP client computer provides health status by sending a message called a statement of health (SoH).
NAP health policy server. A NAP health policy server is a computer running Windows Server 2008 with the Network Policy Server (NPS) role service installed and configured for NAP. The NAP health policy server uses NPS policies and settings to evaluate the health of NAP client computers when they request access to the network, or when their health state changes. Based on the results of this evaluation, the NAP health policy server instructs whether NAP client computers will be granted full or restricted access to the network.
