HP Insight Cluster Management Utility manual Configuring the GUI client on Linux workstations

B.14.1 Configuring the GUI client on Linux workstations

On Linux workstations, you can use a secure ssh tunnel or an X Window server to communicate between the workstation running the HP Insight CMU GUI and the HP Insight CMU management server.

Using an ssh tunnel

1.To open the ssh tunnel, the following settings are required on the HP Insight CMU management server.

•Put Xauth in the PATH. Xauth is typically at:

◦/usr/bin/xauth on Red Hat

◦/usr/bin/X11/xauth on SUSE

Install the following:

◦

◦

◦

On Red Hat: xorg-x11-xauth rpm

On SUSE: xorg-x11-libs rpm

On Debian: xbase-clients.X.X.deb

NOTE: If you did not select the X11 package during your Linux installation, then you must manually install it.

•sshd_config

1.Edit /etc/ssh/sshd_config as follows:

X11Forwarding yes PasswordAuthentication yes

2.Restart sshd.

# /etc/init.d/sshd restart

Stopping	sshd:	[	OK	]
Starting	sshd:	[	OK	]

• Localhost must be resolved and pingable.

2.Verify the ssh tunnel is working correctly.

a.From the GUI workstation, open an ssh connection to the HP Insight CMU management server.

# ssh x.x.x.x -l root

Where x.x.x.x is the IP address of the HP Insight CMU management server.

b.Open an x terminal from the HP Insight CMU management server and the GUI workstation.

# echo $DISPLAY

localhost:11.0

xterm

Using an X Window server

If you do not want to use the ssh tunnel, you must have an X Window Server installed and properly configured. On a Linux workstation, the system must be configured so that it displays an xterm. The configuration might vary depending on the security requirements. For example:

•The X Window system must be listening to the TCP connection. This function is disabled by default. Edit the window manager configuration file to remove this flag. If your display manager is GDM, change the DisallowTCP line in the GDM configuration file (typically /etc/X11/ gdm/gdm.conf for RHEL3 and 4, or /etc/gdm/custom.conf for RHEL5) to false. Next, restart the X Window server.
