A simple lamp. How much intelligence can we add to a simple lamp ? Well that depends …
What we can control?
What we can measure?
On first iteration we will power on and power off.
The results:
To put things one step forward we need to be have all the controls from all the devices across the house in one single place ( a central hub for the house and be able to control it from anywhere )
Creating a Vagrant box from a TFM/GNU Linux image tutorial. It’s an easy 10 step tutorial that will alow you to have a development box based on TFM/GNU Linux
1) Create a new Virtual Machine in VirtualBox
Type: Linux
Version: Linux (64-bit)
Memory Size: 2048MB
New Virtual Disk:
Type: VMDK (Dynamically allocated)
Max Size: 40GB
2) Modify Virtual Machine settings:
* Disable audio
* Disable USB
* Ensure Network Adapter 1 is set to NAT
* Mount the TFM Linux ISO
3) Add the vagrant group and user and set password to vagrant
groupadd vagrant
useradd -m -g vagrant
passwd vagrant
4) Modify /etc/sudoers
Defaults:vagrant !requiretty
#Defaults !visiblepw
Defaults env_keep = “SSH_AUTH_SOCK”
vagrant ALL=NOPASSWD: ALL
5) Add vagrant ssh key to allow logins
mkdir -p /home/vagrant/.ssh
chmod 0700 /home/vagrant/.ssh
wget –no-check-certificate \
https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub \
-O /home/vagrant/.ssh/authorized_keys
chmod 0600 /home/vagrant/.ssh/authorized_keys
chown -R vagrant /home/vagrant/.ssh
6) modify /etc/ssd/sshd_config
Port 22
PubKeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
PermitEmptyPasswords no
PasswordAuthentication no
7) Install the Guest Tools for our VM package.
* From Virtualbox Install Guest Additions…
* from linux prompt:
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
/mnt/cdrom/VBoxLinuxAdditions.run
umount /mnt/cdrom
8) Adjust the base settings of the configuration
echo “dhclient eth0” > /etc/init.d/local
echo “nameserver 8.8.8.8” >/etc/resolv.conf
ln -s /etc/init.d/local /etc/rc.d/rc3.d/S99local
ln -s /etc/init.d/vboxadd /etc/rc.d/rc3.d/S25vboxadd
9) Shutdown the TFM guest OS .
shutdown -h now
10) Pack and distribute the image
vagrant package –base vagrant-tfm
vagrant box add dev-new http://hq.tfm.ro/vagrant/vagrant-tfm.box
vagrant init dev-new
vagrant up
So … Happy developing .
Some thoughts ( depending on what you want that machine for ):
– You will probably want to mount a local directory into VM
– You probably want to start nginx / mysql / php-fpm
– Maybe the you want to add the logs on the local machine …
Fatal error … “libgnutls.so.28: undefined symbol: nettle_secp_224r1”. And that happened after gnutls update. What to do …

Download libreoffice main installer from here. Then unpack the archive intro a directory.
First of all you should get rid of the old LibreOffice and install the new rpms.
rpm -e `rpm -qa | grep liboba` `rpm -qa | grep libreoff`
rpm -Uvh *.rpm
That should be all.
