Red Hat Training
A Red Hat training course is available for Red Hat Enterprise Linux
6.13. Tools
mvapich2
component- The mvapich2 packages use the
GNU Autotools
set of tools (autoconf
,automake
, andlibtool
) to process its configuration. Features included in version 1.12 and later are required, but are not available in Red Hat Enterprise Linux 6.6 and earlier. As a consequence, rebuilding mvapich2 fails with earlier versions ofGNU Autotools
. To work around this problem, uninstall the autoconf, automake, and libtool packages, rebuild mvapich2, and then reinstallGNU Autotools
. freeipmi
component, BZ#1020650- Under certain circumstances, the
IPMI
service is not started and theipmi_devintf
kernel module that provides the device node interface is not loaded. As a consequence, some hardware could reboot unexpectedly after installation before the first intentional reboot. To work around this problem, run the following commands as root:chkconfig --level 345 ipmi on
service ipmi restart
service bmc-watchdog condrestart
Alternatively, log in as root, create the/etc/modprobe.d/watchdog-reboot-workaround.conf
file, and include the following three aliases:- alias acpi:IPI000*:* ipmi_si
- alias acpi:IPI000*:* ipmi_devintf
- alias acpi:IPI000*:* ipmi_msghandler
ssh-keygen
component- The following example in the description of the -V option in the ssh-keygen(1) manual page is incorrect:
“-4w:+4w” (valid from four weeks ago to four weeks from now)
If you set a date range in this format, the certificate is valid from four weeks ago until now. perl-WWW-curl
component- Attempting to access the CURLINFO_PRIVATE value can cause curl to terminate unexpectedly with a segmentation fault.
freerpd
component, BZ#988277- The ALSA plug-in is not supported in Red Hat Enterprise Linux 6. Instead of the ALSA plug-in, use the pulseaudio plug-in. To enable it, use the
--plugin rpdsnd
option with thexfreerdp
command without specifying which plug-in should be used; the pulseaudio plug-in will be used automatically in this case. coolkey
component, BZ#906537- Personal Identity Verification (PIV) Endpoint Cards which support both CAC and PIV interfaces might not work with the latest coolkey update; some signature operations like PKINIT can fail. To work around this problem, downgrade coolkey to the version shipped with Red Hat Enterprise Linux 6.3.
libreport
component- Even if the stored credentials are used , the report-gtk utility can report the following error message:
Wrong settings detected for Red Hat Customer Support [..]
To work around this problem, close the dialog window; theLogin=<rhn-user>
andPassword=<rhn-password>
credentials in the/etc/libreport/plugins/rhtsupport.conf
will be used in the same way they are used by report-rhtsupport.For more information, refer to this Knowledge Base article. vlock
component- When a user password is used to lock a console with vlock, the console can only be unlocked with the user password, not the root password. That is, even if the first inserted password is incorrect, and the user is prompted to provide the root password, entering the root password fails with an error message.
libreoffice
component- Libreoffice contains a number of harmless files used for testing purposes. However, on Microsoft Windows system, these files can trigger false positive alerts on various anti-virus software, such as Microsoft Security Essentials. For example, the alerts can be triggered when scanning the Red Hat Enterprise Linux 6 ISO file.
gnome-power-manager
component- When the computer runs on battery, custom brightness level is not remembered and restored if power saving features like "dim display when idle" or "reduce backlight brightness when idle" are enabled.
rsyslog
component- rsyslog does not reload its configuration after a
SIGHUP
signal is issued. To reload the configuration, thersyslog
daemon needs to be restarted:~]#
service rsyslog restart
