Administering
This section describes how to plan for, install, configure, operate, and manage the SafeLinx Server.
- Overview
  HCL SafeLinx uses standards-based protocols to enable secure access from mobile computing devices outside the firewall to business applications and data on your organization's internal network.
- Security
  HCL SafeLinx includes a range of options for configuring the security of your network, applications, and data.
- Installation planning
  Before you install HCL SafeLinx, verify that you meet the hardware and software requirements, and that the network connections that you want to use are available.
- Roadmaps: Installing and setting up SafeLinx
  The following "roadmap" topics guide you through installing and initially configuring SafeLinx. Refer to the topic that corresponds to your relational database and server operating system.
- Installing and initial configuration
  Initial configuration and installation of HCL SafeLinx varies based on your operating system and relational database.
- Adding a secure login profile
  By default, the SafeLinx Administrator communicates with the access manager over an unencrypted connection. If you want the connection between the SafeLinx Administrator and the access manager to use transport layer security (TLS) protocols, add a secure login profile to the SafeLinx Administrator.
- Adding and configuring resources
  After you complete the installation and initial configuration, continue to prepare the deployment by configuring other network resources.
- Administering
  The SafeLinx Administrator administration client is the primary tool for viewing, adding, configuring, and managing HCL SafeLinx resources. Along with the SafeLinx Administrator, you can use the HCL SafeLinx Monitor to view information about packet flow through the SafeLinx Server. You can also use a set of command line tools to perform common SafeLinx Server tasks.
- Programming reference
  There are several programming considerations of which you might want to take advantage.
- Database schema information
  HCL SafeLinx uses a DB2, Oracle, MySQL, or SQL database to store tables of information about current and past activity of SafeLinx Server sessions. The following tables are created and accessed by using the qualifier name wg for DB2 installations.

Installing the SafeLinx server and the SafeLinx Administrator client

Install the SafeLinx server and then the SafeLinx Administrator client.

Before you begin

Complete the steps described in Preparing for SafeLinx for Nomad.

Procedure

Install the SafeLinx server:
1. Switch to the installer directory created previously in which you copied the install files:
2. Extract the SafeLinx server installer:
```
tar -xvf HCL-SafeLinx-<version>-x86_64.tar.gz
```
3. List the new inst.images directory that contains the SafeLinx server installer:
```
ls
```
4. Switch to the inst.images directory and list the files:
```
cd inst.images
ls
```
5. Install the SafeLinx server:
```
sudo ./install_wg
```
  The following message is shown, indicating that the SafeLinx server detects the MySQL ODBC drivers:
```
MYSQL ODBC drivers were found on this machine and will be used by the Connection Manager. MySQL Client was found with version: 8.0.25
```
6. Complete the SafeLinx server installation. When prompted, enter y for SAML Service provider support (only if required) and enter y to start SafeLinx when the system boots.
```
Install SAML Service Provider support? [y] 
Start SafeLinx when the system boots? [y]
```
Install the SafeLinx Administrator client:
1. Switch to the installer directory created previously in which you copied the install files.
2. Install the SafeLinx Administrator client:
```
sudo rpm -ivh HCL-SafeLinx-wgcfg-<version>.x86_64.rpm
```
Optional: Copy the certificate file from the cert directory created previously to the SafeLinx server application directory, /opt/hcl/SafeLinx. If you skip this step, you must specify an absolute path to the certificate file when you configure the SafeLinx server in the next procedure.
1. Use the cd command to switch to the cert directory:
2. Copy slselfsign.p12 to the directory/opt/hcl/SafeLinx:
  Note: As stated previously, although this example uses a self-signed certificate, in a production environment, using a third-party certificate issued by a trusted certificate authority is recommended.
```
sudo cp slselfsign.p12 /opt/hcl/SafeLinx/
```

What to do next
