Agent Third-Party Deployment: Configuring the Operation Mode on UNIX

FlexNet Manager Suite ()

Before the installation, you can configure to install the FlexNet Inventory Agent into either of the following two operation modes on the target UNIX system:

• Default operation mode—The installed agent will run as the root user and requires full root access.
• Least privilege operation mode—The installed agent will run as the flxrasvc standard user.

Important: You can upgrade an existing agent that has been installed for the default operation mode to the least privilege operation mode. However, if an agent has been installed for the least privilege operation mode, you cannot change it to the full privileged default operation mode. To change an agent from the least privilege operation mode to the default operation mode, you must uninstall and re-install the agent.

Important: If an agent has been installed for the least privilege operation mode, it is not able to perform self-upgrade to new versions.

Configuring for the default operation mode

By default, an agent will be installed or upgraded for the default operation mode. However, if you are upgrading an existing agent from the least privilege operation mode to the default operation mode, make sure that your bootstrap configuration file is correctly configured for the default operation mode. For details, see Agent Third-Party Deployment: Configuring the Bootstrap File for UNIX.

Configuring for the least privilege operation mode

To install the agent for the least privilege operation mode on UNIX, you need to complete the following tasks before the installation:

1. Configure the bootstrap file for the least privilege operation mode by following the instructions in Agent Third-Party Deployment: Configuring the Bootstrap File for UNIX.

2. Make sure sudo is installed on the target UNIX system and the path to the sudo binary is set in the PATH environment.

3. Configure sudo on the target UNIX system to grant privilege to the required tools according to the following table. For a sample sudoers file to configure sudo, see Agent Third-Party Deployment: Sample Sudoers File.

   Important:

   • Always use visudo to edit and verify a sudoers file, and ensure the changes do not corrupt the sudoers file which can cause sudo to be inoperable.

   • Some systems (notably Red Hat) have a sudoers entry Defaults requiretty that prevents running sudo when no tty is present. The agent requests sudo to run without any prompts, but this entry still causes sudo to fail without a tty, which will result in the agent being unable to launch necessary utilities through sudo even though the sudoers file has granted them the access. To avoid this issue, the Defaults requiretty entry must be removed from the sudoers file. For more information, see Bug 1020147 on Red Hat Bugzilla.

   • Some systems (notably Red Hat) might require the EXEC option to be set in the sudoers file for the execution of Java binaries to get version and product information. For example:

     flxrasvc ALL=(ALL) EXEC: NOPASSWD: FLEXERAOS, FLEXERA

   The following table provides information about which tools require sudo privilege on which platforms for an agent running in the least privilege operation mode.

Tool/Path	Tool function	Platform requiring `sudo` privilege	Consequence of missing `sudo` privilege
**Non-Flexera tools**
- `/sbin/ifconfig` or `/usr/sbin/ifconfig` - and `/usr/sbin/dladm`	Obtain network interface data	Solaris	Network interface data missing
`/usr/sbin/dmidecode`	Obtain hardware serial number	Linux x86 Solaris x86	Serial number missing
`/usr/sbin/sysctl`	Obtain TCPKeepAlive information	macOS	TCPKeepAlive information missing
`db2licm`**Note:** The path to `db2licm` depends on where DB2 is installed. That path needs to be added to sudoers.	Launched to obtain inventory for IBM DB2	All supported Unix platforms	IBM DB2 inventory missing or incomplete
`/usr/sbin/subscription-manager`	Obtain Red Hat subscription information	Linux	Subscription data missing
**Flexera agent tools****Note:** Paths to Flexera agent tools are dependent on where the agent is installed. The default base installation path is `/opt/managesoft/`. Your custom installation path might be different if your platform supports custom installation path. For a list of platforms that support custom installation path, see Agent Third-Party Deployment: Installing FlexNet inventory agent on UNIX.
`/opt/managesoft/libexec/flxecmc`	Obtain hardware properties used to generate and validate the local agent ID	Linux**Note:** Sudo privilege for flxecmc should not be revoked once it has been provided on any given Linux machine. Doing so will cause the agent ID to not be reported even if the machine currently has a valid ID.	Agent ID not generated or an existing ID not validated
`/opt/managesoft/libexec/flxfsscan`	Run file system scan and provide ability to read file data and metadata	All supported Unix platforms	Data missing on inventory reliant on file scan \(Oracle, Oracle FMW, Java, Jboss, supported installation evidence types\)
`/opt/managesoft/libexec/flxoracleinv`	Provide impersonation for running Oracle database queries scripts used in obtaining Oracle inventory	All supported Unix platforms	Oracle database inventory missing
`/opt/managesoft/libexec/flxping`	Implement custom ping support for `MgsPing` net selector algorithm	All supported Unix platforms	`MgsPing` net selector algorithm failing to rank multiple beacon connections
`/opt/managesoft/libexec/flxps`	Obtain currently running process data	All supported Unix platforms	Data missing on inventory reliant on running process data \(usage, Oracle, Oracle FMW, Java, and IBM MQ\)
`/opt/managesoft/libexec/flxsysinfo`	Obtain local disk drive data	Linux	Disk drive data missing
`/opt/managesoft/libexec/flxupgrade`	Runs platform specific install packages to support self-upgrade	All supported Unix platforms	Least privilege agents will not be able to support self-upgrade. This tool can be ignored for customers that do not use the agent's self-upgrade functionality.

For more details about the least privilege operation mode, such as what happens at installation, what processes are launched and how to run agent component directly after the installation, see Agent Third-Party Deployment: Least Privilege Operation Mode.
