Take Out What You Need

Remove the Sensor, keyboard, mouse, and power cord from the box.

Before You Continue

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

A VGA monitor.
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.

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. Connect the VGA monitor, keyboard, and mouse 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 for Ethernet, a concentrator for Fast Ethernet, or an MAU for Token Ring or Single-Attached FDDI. If attaching to a Dual-Attached FDDI ring, the Sensor becomes part of the FDDI ring, with cables connecting it directly to the router and the next segment of the ring.

Initialize the Sensor

1. Power on the Sensor and monitor.

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

Use the passwd command to change the default password to the designated password.

3. Type sysconfig-sensor at the command prompt.

4. To configure the Sensor, use the following table:

Confirm Setup

1. After running sysconfig-sensor, type init 6 to reboot the Sensor.

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

The Sensor prompts you to change user netrangr's password after the first login.

3. Scan through NetRanger's error log files by typing:

more /usr/nr/var/errors.*

4. Type nrvers to display a list of running services.

loggerd, sapd, postofficed, configd, and fileXfer should display with the following format:

<service> <version_number> release <date>

5. 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. Contact the Technical Assistance Center at 800-553-2447 in case of technical difficulty.
