5.5.1. Configuring the GCap for the first connection

5.5.1.1. Introduction

The procedure described here explains how to set up the GCap when it is first installed.

---

5.5.1.2. Prerequisites

• User: setup

---

5.5.1.3. Preliminary operations

• Check that the LUKS key is connected to the GCap.

Note

If there is no LUKS key or if it is the wrong one, the operating system will not be able to access the contents on the hard drives.

In case of problems, check:

• Whether the correct key is used and not one from another GCap...

• The USB port is working properly: change the USB port

• Connect to the GCap.

• Depending on the situation:

  • Either connect directly to the GCap via keyboard and screen (see Procedure for connecting directly to the GCap)

  • Or connect to the GCap via the iDRAC (see Procedure for connecting to the GCap via the iDRAC)

• Connect as setup.

Note

The first time you log in to the GCap, a prompt to change your password will be displayed.

Make sure the keyboard configuration is correct (fr or en version).

• If needed, manage the aggregation of detection interfaces: see the Procedure for managing the aggregation of capture interfaces.

• If needed, manage the high availability of GCaps: see Procedure for managing the high availability of GCaps.

• Pairing the GCap with the GCenter: see the Procedure for pairing a GCap with a GCenter.

  • On the GCenter,

    • Connect via an SSH

    • Know the GCenter IP address

  • On the GCap, enter the IP address of the GCenter
