Before You Continue

Before you continue setting up your NetRanger Sensor, you must have the following:

Network cables
Designated passwords for users root and netrangr
Designated information for the Sensor host, as listed in the table in the "Initialize the Sensor" section of this Quick Reference Guide

Note If you do not want to use the LapLink cable that was shipped with your sensor, you must have a VGA monitor and keyboard.

Place the Sensor on the Network

1. Attach the power cord to the Sensor and plug it into a power source (a UPS is recommended).

2. Use the LapLink cable to attach a laptop to the Sensor's COM1 port, or connect a VGA monitor and keyboard to the Sensor.

3. Identify the type of network configuration you have by comparing the Sensor rear panel to the diagram below:

4. Use the following diagram to attach the Sensor to the network:

Note The "Monitoring Point" can be a hub (Ethernet), a concentrator (Fast Ethernet), or an MAU (Token Ring/SFDDI). If the Sensor is attached to a Dual-attached FDDI ring, the Sensor itself becomes part of the FDDI ring.

Initialize the Sensor

1. Power on the Sensor.

2. Log on as user root. The default root password is attack.

The system prompts you to change the default password.

3. Type sysconfig-sensor at the command prompt.

more /usr/nr/var/errors.*

3. Type nrstatus to display a list of running services.

The following services should be running: loggerd, sapd, postofficed, configd, and fileXferd.

4. Type nrconns to display the Sensor's connection status.

If the Director has not been configured, the output of the nrconns command should indicate communication failure:

<Director_Host_Name>.<Director_Org_Name> Connection 1: <Director_IP_Address> 45000 1 [SynSent] sto:5000   syn NOT rcvd!

Make sure that you finalize the Sensor configuration by running nrConfigure on the Director. Refer to the NetRanger User Guide for more information.
