Vlan Experiment

Recently I am busy with configurating the LXC networking in Cloudstack, so following is how I understanding the vlan experiment on how to understand the public/private/management networking in CloudStack.

Prerequisite

Prepare 2 virtual machine of CentOS6.7, each connected to a seperated networking.
Machine 1, dhcp, got 10.47.58.203. Named vlan1.
Machine 2, dhcp, got 10.47.58.214. Named vlan2.

Install Software

For easily configure 802.1Q vlan tagging networking in CentOS7, install following packages.

$ yum install vconfig

Vlan Configurating

Configure like following:

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
#BOOTPROTO="dhcp"
BOOTPROTO="none"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0.100 
DEVICE=eth0.100
ONBOOT=yes
HOTPLUG=no
BOOTPROTO=none
TYPE=Ethernet
VLAN=yes
IPADDR=192.168.42.11
NETMASK=255.255.255.0

In another machine, configure the eth0.100 as 192.168.42.12, after reboot, they could be reached via this vlan tagging 100 address.

Tips on Veewee and Vagrant

Install Veewee

First you should get rvm avaiable, then use rvm for install ruby-2.2.1:
Note: you should import gpg signature via commandline.

$ proxychains4 curl -k --insecure  -L https://get.rvm.io | bash -s stable --ruby
$ proxychains4 rvm install ruby-2.2.1 

Install the veewee via:

$ proxychains4 gem install bundler
$ git clone https://github.com/jedi4ever/veewee.git
$ cd veewee
$ proxychains4 gem install i18n -v '0.7.0'
$ proxychains4 bundle install

After installation createing an alias for quickly refers to veewee:

$ alias veewee="bundle exec veewee version"

Bug-fix: for adding net/scp in the Gemfile:

$ vim Gemfile
.......
+ gem "net-scp"
gemspec

Install Vagrant

Since the vagrant provided via Ubuntu14.04 is pretty old, we have to download it from vagrant’s official website and dpkg install it.

Install veewee plugins:

$ proxychains4 vagrant plugin install veewee

Create new definition

Create new definition via:

$ veewee vbox define awesome-ubuntu-server ubuntu-14.04-server-amd64
The basebox 'awesome-ubuntu-server' has been successfully created from the template
'ubuntu-14.04-server-amd64'
You can now edit the definition files stored in
/home/dash/Code/veewee/definitions/awesome-ubuntu-server or build the box with:
veewee vbox build 'awesome-ubuntu-server' --workdir=/home/dash/Code/veewee

Now start building:

$ veewee vbox build awesome-ubuntu-server

Speed-up Building

Use Local Installation ISO:

$ vim definitions/awesome-ubuntu-server/definition.rb
+   :iso_src => "http://192.168.0.79/iso/ubuntu-14.04-server-amd64.iso",
$ vim ./lib/veewee/provider/virtualbox/box/helper/guest_additions.rb
+          url="http://192.168.0.79/iso/#{isofile}"

Force ruby for using local installation:

$ vim definitions/awesome-ubuntu-server/ruby.sh
......
wget http://192.168.0.79/iso/veewee/ruby-$RUBY_VERSION.tar.gz
tar xvzf ruby-$RUBY_VERSION.tar.gz
......
RUBYGEMS_VERSION=2.1.10
wget http://192.168.0.79/iso/veewee/rubygems-$RUBYGEMS_VERSION.tgz

File Position

The generated image position is listed in:

➜  awesome-ubuntu-server  pwd
/home/dash/VirtualBox VMs/awesome-ubuntu-server
➜  awesome-ubuntu-server  du -hs *
3.2G    awesome-ubuntu-server1.vdi
8.0K    awesome-ubuntu-server.vbox
8.0K    awesome-ubuntu-server.vbox-prev
68K     Logs

rtl-sdr steps

Installing and configurating steps:

$ git clone https://github.com/balint256/gr-baz
$ sudo apt-get install libboost-all-dev gr-osmosdr gnuradio-dev liblog4cpp5-dev 
$ cd gr-baz
$ mkdir build
$ cd build
$ cmake ..
$ make && sudo make install

Install rtl-sdr:

$ git clone git://git.osmocom.org/rtl-sdr.git 
$ cd rtl-sdr 
$ mkdir build
$ cd build/
$ cmake ../ -DINSTALL_UDEV_RULES=ON
$ sudo make install
$ sudo ldconfig 

Now you could use sudo rtl_eeprom for probing the rtl equipments.

$ sudo modprobe -r dvb_usb_rtl28xxu
$ sudo apt-get install -y gqrx-sdr

Using gqrx could scan the frequency and get the radio stations.

Integrate FreeNAS

Use Virtualbox for integrating FreeNAS.

Add Disks

Add a new SCSI controller and two disks:

Then in FreeNAS, import this new disks via:

Volume Manager

Add volume of added 2 disks:

Continue:

After added:

ISCSI Sharing

Create new sharing:

Add portal:

Add Initiator:

Add Target:

Add Extent:

Extend options:

Associate:

Enable the iscsi service:

Integration

Integaration with cloudstack would be looked like following:

Using NFS for testing.
