3.12 Installing RLM Server

Access to a Reprise License Manager (RLM) server is required when using Remote Visualization and/or Nitro.

The RLM Server can run multiple licenses. If your company already uses an RLM Server, you do not need to install a new one for Remote Visualization or Nitro. However, Remote Visualization and Nitro will use a different port than the default RLM Server port (5053). Skip this topic and follow the instructions in 3.13 Installing Remote Visualization or 3.15 Installing Nitro as applicable.

The RLM v12.1 (build:2) release resolved memory leak and security issues. The RLM package available with Moab HPC Suite 9.0.2, contains the v12.1 (build:2) release. Adaptive Computing strongly recommends that your RLM Server is v12.1 (build:2).

This topic contains instructions on how to install an RLM Server.

3.12.1 Open Necessary Ports

If your site is running firewall software on its hosts, you will need to configure the firewall to allow connections to the necessary ports.

These instructions assume you are using the default ports. If your configuration will use other ports, then substitute your port numbers when opening the ports.

On the RLM Server do the following:

  1. Open the RLM Server port (5053) and the RLM Web Interface port (5054).
    [root]# iptables-save > /tmp/iptables.mod
[root]# vi /tmp/iptables.mod

# Add the following lines immediately *before* the line matching
# "-A INPUT -j REJECT --reject-with icmp-host-prohibited"

-A INPUT -p tcp --dport 5053:5054 -j ACCEPT

[root]# iptables-restore < /tmp/iptables.mod
[root]# service iptables save
  2. If Remote Visualization is part of your configuration, open the Remote Visualization port (57889).
    [root]# iptables-save > /tmp/iptables.mod
[root]# vi /tmp/iptables.mod

# Add the following lines immediately *before* the line matching
# "-A INPUT -j REJECT --reject-with icmp-host-prohibited"

-A INPUT -p tcp --dport 57889 -j ACCEPT

[root]# iptables-restore < /tmp/iptables.mod
[root]# service iptables save
  3. If Nitro is part of your configuration, open the ISV adapativeco port for the Adaptive license-enabled products (for example: 5135).
    [root]# iptables-save > /tmp/iptables.mod
[root]# vi /tmp/iptables.mod

# Add the following lines immediately *before* the line matching
# "-A INPUT -j REJECT --reject-with icmp-host-prohibited"

-A INPUT -p tcp --dport 5135 -j ACCEPT

[root]# iptables-restore < /tmp/iptables.mod
[root]# service iptables save

3.12.2 Install the RLM Server

If your configuration uses firewalls, you must also open the necessary ports before installing Nitro. See 3.12.1 Open Necessary Ports.

On the host on where the RLM Server will reside, do the following:

  1. If you are installing RLM Server on its own host or on a host that does not have another RPM installation, complete the steps to prepare the host. See 3.2 Preparing the Host – Typical Method or 3.4 Preparing the Host – Offline Method.
  2. Install the RPM.
    [root]# yum install ac-rlm

3.12.3 Change the Default Passwords

The RLM Web interface includes two usernames (admin and user) by default. These usernames have the default password "changeme!".

If you do not change this password, RLM, and Remote Visualization, will not be secure. For tips on choosing a good password, see https://www.us-cert.gov/ncas/tips/ST04-002.

Do the following for both the user and the admin usernames:

  1. Using a web browser, navigate to your RLM instance. (http://<RLM_host>:5054; where <RLM_host> is the IP address or name of the RLM Server Host).

    If you have problems connecting using the web browser, on the RLM server check /opt/rlm/rlm.dll for error information.

  2. Log in.
  3. Select Change Password and change the password according to your password security process.

The password for "user" will be needed as part of the Remote Visualization installation.
