HowTo: Free IPA on Fedora

InstallAndDeploy - Free IPA

The above link is mostly correct, but a few changes for Fedora 16 and above.

systemctl disable NetworkManager.service
chkconfig network on
systemctl start network.service

# IPA isn't enabled by default (yet)
systemctl enable ipa.service
systemctl restart sshd.service
systemctl start ipa.service
# Set up your local browser with the IPA cert.
firefox http://localhost

# Define this machine as a client to the new server.

ipa-ldap-updater --test

Problem: system-config-authentication doesn't work with IPA yet.
Solution: ipa-client-install (Thank you sgallagh)
Watch for this bug 731094 to be resolved as well.
On the root server, ipa-client-install is done as part of ipa-server-install.

Problem: IPA and Dirsrv not started.
/var/log/messages: startup - The default password storage scheme SSHA could not be read or was not found in the file /etc/dirsrv/slapd-PKI-IPA/dse.ldif. It is mandatory.

On a hard shutdown, the dse.ldif files were empty.

[root@montechristo ~]# locate dse.ldif

Solution: Copy dse.ldif bak files, and restart services.

cp /etc/dirsrv/slapd-PKI-IPA/dse.ldif.bak /etc/dirsrv/slapd-PKI-IPA/dse.ldif
systemctl restart dirsrv@PKI-IPA.service
cp /etc/dirsrv/slapd-SOLENGTECH-BIZ-TM/dse.ldif.bak /etc/dirsrv/slapd-SOLENGTECH-BIZ-TM/dse.ldif
systemctl start dirsrv@SOLENGTECH-BIZ-TM.service
systemctl start ipa.service

HowTo: Change default OS in Grub2 Fedora

Grub2 - FedoraProject

I'm having trouble with kmod-nvidia keeping up with the kernels. So I need to change the default OS more than I'd like on Fedora 16...

Note, the Grub2 rules for Ubuntu are different than Fedora, and conflict.

Whenever you change the drives or OS you need to generate a new configuration file.

grub2-mkconfig -o /boot/grub2/grub.cfg
It will display a list of OS files found, Windows and Linux.
Found linux image: /boot/vmlinuz-3.2.3-2.fc16.x86_64
Found initrd image: /boot/initramfs-3.2.3-2.fc16.x86_64.img
Found linux image: /boot/vmlinuz-3.1.9-1.fc16.x86_64
Found initrd image: /boot/initramfs-3.1.9-1.fc16.x86_64.img
Found Windows NT/2000/XP (loader) on /dev/sdc1

To list the found OS's:
grep menuentry /boot/grub2/grub.cfg

menuentry 'Fedora Linux, with Linux 3.2.3-2.fc16.x86_64' --class fedora --class gnu-linux --class gnu --class os {
menuentry 'Fedora Linux, with Linux 3.1.9-1.fc16.x86_64' --class fedora --class gnu-linux --class gnu --class os {
menuentry "Windows NT/2000/XP (loader) (on /dev/sdc1)" --class windows --class os {

To check, by name, the saved entry:
grub2-editenv list
saved_entry=Fedora Linux, with Linux 3.1.9-1.fc16.x86_64

If you have not changed disk drives or partitions, start here
To boot the previous OS (i.e. Linux 3.1.9-1):
grub2-set-default 1
To boot the usual OS: (once everything is working again)
grub2-set-default 0
</pre> with the title of the newly installed Fedora's entry. From that point on you can change the default by calling <pre>grub2-set-default <title or number></pre> or view it by running <pre>grub2-editenv list</pre> <p>To do that, you'll need the list of possible menu entries, which you can find with </p> <pre>grep menuentry /boot/grub2/grub.cfg<br /><br /><br /></pre><br />

HowTo: Install GNOME 3 Shell Extensions

Five must have Gnome shell extensions for Fedora 15 « Justin Stories

Earlier, I've blogged on the difficult to install weather extension (Rick Foos HowTo Blog: Gnome Shell Weather Extension ~ Web ...).

So how do you install GNOME 3 Shell Extensions?

First, Remember - Must Reset Desktop when Changing Shell Extensions
Alt-[F2], r

...Ubuntu is mostly the same with apt-get instead of yum...After you install the extensions, exactly the same...

# Install GUI to manage shell extensions.
yum -y install gnome-tweak-tool

# What are the available shell extensions?
yum list gnome-shell-extension-*

A list follows with some possibilities...

gnome-shell-extension-xrandr-indicator.noarch 3.2.3-1.fc16 updates
# If you're not one to mess around, install them all...You can always remove them later...
yum install gnome-shell-extension-*

# Enable/Disable Shell Extensions from a gui.

While many of them may not do what you expect, some are good.

Some extensions will need settings to be customized.

# Find where the settings for a shell extension are located.
# NOTE: Extensions may or may not have 'extension' in their schema name.
gsettings list-schemas

# Find the current settings, for an extension.
# if you have a keyword to grep, you can use that or copy one of the schemas from the list.
gsettings list-recursively $(gsettings list-schemas | grep weather) city '' position-in-panel 'center' show-comment-in-panel true show-text-in-panel true translate-condition true unit 'fahrenheit' use-symbolic-icons false woeid 'USTX0058'

# Find out what the valid settings are...
# Most useful for enums, otherwise just reports the data type and none exactly say what will happen...
gsettings range unit


# Change a setting
gsettings set unit 'fahrenheit'

Now you are an unintended expert in GNOME 3 shell extensions...This is a step backward, there was a GUI to add shell extensions in GNOME 2...I had no intention of becoming a shell extension expert...So I'm an unintended expert...
