Installing and Configuring Linux Access Gateway on RHEL

novdocx (en) 17 September 2009

Installing and Configuring Linux

Access Gateway on RHEL

The Novell®Access Manager Linux Access Gateway is a software appliance designed on the

SUSE®Linux Enterprise Server (SLES) 9 SP3 kernel. In the standard installation procedure, Linux

Access Gateway re-images the hard drive, embeds the Linux operating system, then configures the

embedded operating system for optimal performance. However, when you have an existing RHEL

server on which you want to install the Novell Access Manager Linux Access Gateway, the

installation is performed against a free hard disk partition on the existing RHEL server.

The following sections describe the procedure to install Linux Access Gateway in the advanced

installation mode on RHEL 5.1. For detailed instructions, see Chapter 3, “Additional Information

on Installing And Configuring,” on page 15.

Section 1.1, “System Requirements,” on page 9

Section 1.2, “Installing and Configuring the Linux Access Gateway on RHEL,” on page 10

1.1 System Requirements

This section explains the requirements for installing the Novell Access Manager Linux Access

Gateway:

Section 1.1.1, “Hardware Requirements,” on page 9

Section 1.1.2, “Linux Access Gateway Network Requirements,” on page 9

1.1.1 Hardware Requirements

3 GB memory

Hard disk with a free partition of 100 GB--other than the / (root) partition--either as

unformatted and unallocated free space or as an additional partition in the existing server.

3.0 GHz processor or better recommended, with 2.0 GHz as the minimum.

1.1.2 Linux Access Gateway Network Requirements

The Linux Appliance runs on SLES 9 SP3. The Linux Appliance has no software requirements.

Before proceeding with the installation, make sure you have a static IP address for your Linux

Access Gateway server and an assigned DNS name (host name and domain name). You need to

know the following about your network:

The subnet mask that corresponds to the IP address of the Access Gateway.

The IP address of the default gateway.

The IP addresses of the DNS servers on your network. These DNS servers need to be

configured to resolve the DNS name of the Access Gateway to the IP address that you assign to

it.

The IP address or DNS name of a MCP server, if you have one in your local environment.

You are prompted to enter this information during the install.

1.2 Installing and Configuring the Linux Access

Gateway on RHEL

1Install Linux Access Gateway in the Advanced Installation mode.

2(Conditional) If you are installing Linux Access Gateway on an existing partition, other than

the / (root) partition in RHEL, remove the existing partition.

3Create a new extended partition with the End Cylinder value as 100 GB. Create the following

partitions:

/ (root) partition with Ext3 File system and End cylinder value of 30 GB.

var partition with Ext3 file system and End Cylinder value of 20 GB.

COS partition that uses the remaining space (50GB) on the hard disk. Select 0x68 Novell

COS as the File System ID.

For more information on removing or creating partition, see Section 3.3, “Installing the Linux

Access Gateway,” on page 16.

4Complete the installation of Linux Access Gateway. For more information, see Section 3.3,

“Installing the Linux Access Gateway,” on page 16.

When the installation is completed, the hard disk is formatted, removing all data, and the

partitions are created. After all the packages are installed, the system reboots in SUSE®Linux

Enterprise Server (SLES) 9, and finishes the installation.

5The system reboots with SLES 9.

6Login to the Novell Access Manager Administration Console and verify that the Linux Access

Gateway is imported. For more information, seeSection 3.5, “Verifying the Linux Access

Gateway Installation on RHEL,” on page 34.

7Complete the following hardware and system services configuration:

Network Interface Configuration: If you do not configure the network interface, the

Linux Appliance setup fails. Make sure that Network configuration matches the RHEL

configuration.

Administration Console Configuration: In the Administration Console Configuration

screen, specify the IP address of the RHEL server as the Access Gateway IP address.

For more information on configuring, see Section 3.4, “Configuring Hardware and System

Services,” on page 27.

8After the installation of Linux Access Gateway, the machine starts in SUSE Linux Enterprise

Server (SLES) 9 SP3. To boot the machine from Red Hat, copy boot entries for Red Hat to the

Linux Access Gateway machine. For more information, see Section 3.6, “Configuring the

Linux Access Gateway to Boot from RHEL,” on page 35.

9To start the Linux Access Gateway in RHEL, login to RHEL machine as root, then do the

following:

9a Set SELinux to Permissive mode.

9b Disable firewall.

9c Copy the

rhel-lag.tar.gz

file to the RHEL machine.

9d Untar the files and run the

/opt/novell/access-gateway/scripts/configure-

lag.sh

script. This script mounts the partition and modifies fstab entry and syslog.
