User`s guide

• To configure connected mode, specify CONNECTED_MODE=yes in the file.

• To configure datagram mode, either specify CONNECTED_MODE=no in the file or do not specify this

setting at all (datagram mode is enabled by default).

Note

Before saving your changes, make sure that you have not specified more than

one setting for CONNECTED_MODE in the file.

2. To enable the specified mode on the interface, use the following commands to take down the interface

and bring it back up:

# ifdown ibN

# ifup ibN

libfprint

The following message might appear in dmesg or /var/log/messages:

WARNING! power/level is deprecated; use power/control instead.

The USB subsystem in UEK R3 deprecates the power/level sysfs attribute in favor of the power/

control attribute. The libfprint fingerprinting library triggers this warning via udev rules that try to

use the old attribute first. You can safely ignore this warning. The setting of the appropriate power level still

succeeds. (Bug ID 13523418)

Large memory system fails to boot

If a large memory system fails to start, boot it using an alternate kernel to UEK R3 and disable the kdump

service before booting into the UEK R3 kernel:

# chkconfig kdump off

Linux Containers (LXC)

• The correct operation of containers might require that you completely disable SELinux on the host

system. For example, SELinux can interfere with container operation under the following conditions:

• Running the halt or shutdown command from inside the container hangs the container or results in

a permission denied error. (An alternate workaround is to use the init 0 command from inside

the container to shut it down.)

• Setting a password inside the container results in a permission denied error, even when run as

root.

• You want to allow ssh logins to the container.

To disable SELinux on the host:

1. Edit the configuration file for SELinux, /etc/selinux/config and set the value of the SELINUX

directive to disabled.
