Using setuid_launcher to configure secure launcher permissions

Using setuid_launcher to configure secure launcher permissions

This section contains instructions for using setuid_launcher to give agents elevated permissions.

To set up secure launcher permissions using the configuration interface and setuid_launcher:
1
Follow the instructions in To launch the Agent Manager Installation and Configuration interface: or To launch the Agent Manager configuration command-line interface: .
2
Navigate to the Configure Secure Launcher screen or the Secure Launcher step.
3
Set the path to point to the setuid_launcher executable. This executable is located in <fglam_home>/bin/setuid_launcher.
4
Exit from the configuration interface as described in To launch the Agent Manager Installation and Configuration interface: or To launch the Agent Manager configuration command-line interface: .
5
Use the command chmod u+s to set the sticky bit on <fglam_home>/bin/setuid_launcher.
6
Change the owner of <fglam_home>/bin/setuid_launcher to root. This permits the agents that need root privileges to be run as the root user without requiring a password.

If these permissions are no longer needed, issue the following command:

chmod u-s <fglam_home>/bin/setuid_launcher

To set up secure launcher permissions using fglam.config.xml and setuid_launcher:
1
Navigate to <fglam_home>/state/default/config.
2
Open the fglam.config.xml file for editing.
3
Edit the <config:path> element under <config:secure-launcher> to point to your local setuid_launcher executable. This executable is located in <fglam_home>/bin/setuid_launcher.
4
Issue the command chmod u+s to set the sticky bit on <fglam_home>/bin/setuid_launcher.
5
Change the owner of <fglam_home>/bin/setuid_launcher to root. This permits the agents that need root privileges to be run as the root user without requiring a password.
6
If these permissions are no longer needed, issue the command:
chmod u-s <fglam_home>/bin/setuid_launcher

Using the HP patch checking tool

The tool is available from http://www.hp.com/go/java.

To use the tool, issue the following command:

java -jar ./HPjconfig.jar -nogui -patches -listmis -javavers 6.0

About Agent Manager installations on AIX

About Agent Manager installations on AIX

On newly installed AIX® systems, the base operating system can be further customized by the install_assist program provided by IBM®. By default, this program is listed in the /etc/inittab file so that it starts automatically when the system is started.

When install_assist runs automatically, it can interfere with the Agent Manager startup scripts that are installed in /etc/rc.d/rc2.d, and with other startup scripts, such as those provided by OpenSSH.

To prevent install_assist from starting automatically:
1
Edit the /etc/inittab file.
 
* 
TIP: You can edit the file directly, or by running the following command as root:

# rmitab install_assist

2
Remove the following line from the /etc/inittab file:
install_assist:2:wait:/usr/sbin/install_assist </dev/console >/dev/console 2>&1

Preventing Agent Manager core dumps on Linux

Installing and running the Agent Manager on a Linux® machine with several interfaces can result in a core dump with the following console output:

*** glibc detected ***
...
malloc(): memory corruption:
...
Java_java_net_NetworkInterface_getAll+0x8c

This error is related to a known JavaTM 6 issue, JDK-7078386. This issue is resolved in Java 7. For more information about JDK-7078386, you can visit http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7078386.

To prevent an Agent Manager core dump on a Linux machine:
1
Before installing the Agent Manager, install Java 7 update 45 on the machine where you plan to install the Agent Manager.
2
On this machine, install the Agent Manager, and navigate to the following directory: <fglam_home>/state/default/config.
3
In this directory, locate and open the vm.config file for editing.
4
In the vm.config file, search for the java.vm property, and edit its value to point to the new JDK 7 installation.
5
Save your changes to the vm.config file, and close it.
6
Start up the Agent Manager.
