Configuring the Sensor

4.6 Sensor Network Settings

You may need to change the sensor’s network settings when installing to a non-DHCP

network where a Default Gateway, DNS Server and Domain name are used, or when

moving the sensor from one network to another.

1. Open In-Sight Explorer and log on to the sensor.

2. On the Sensor menu, click Network Settings to open the Network Settings dialog

(Figure 4-7).

Figure 4-7: Network Settings Dialog

The following network settings can be changed using the Network Settings dialog:

• Host Name: Defines the name of the In-Sight sensor as it will appear in the In-Sight

Network. Each In-Sight sensor has its Host Name set automatically the first time it

boots. For example, an In-Sight 5100 sensor's Host Name is "is5100_xxxxxx". For

an In-Sight 5400C sensor, the Host Name is "is5400C_xxxxxx"; an In-Sight 5400R

sensor’s Host Name is “is5400R_xxxxxx”. For every sensor, "xxxxxx" is given by the

last 6 characters of the sensor's unique MAC address. For example, an In-Sight

5100 sensor with the MAC address 00-d0-24-01-02-03 is assigned the Host Name,

"is5100_010203". If the local system is a networked PC running the In-Sight

Explorer software, then the Host Name is automatically inherited from the Computer

Name defined in the Windows operating system.

• IP Address: Assigns a unique identifier for each In-Sight sensor on the network,

which must be consistent with the IP address-numbering scheme of the local

network.

• Subnet Mask: Defines which part of the IP address refers to the network and which

part refers to the host. The network part of the IP address is the same for all hosts

on the same subnet, and the remainder is unique to each host.
