HOWTO IMPORT OVA (from VMware) to PROXMOX 5.x

 HOWTO IMPORT OVA (from VMware) to PROXMOX 5.x

        Hi All may be someone has faced to import an OVA (created with VMware) to PROXMOX one time. I have created two scripts :

The first one is checking proxmox's iso folder to see if ova file are there. The second  convert and import the OVA file into proxmox and you can start the KVM VM.

Both are launch separately !

IT can be better I'm in the beginning , so feel free to help me imrove thess scripts.

Don't hesitate to contact me, IT will be a pleasure to help you.

The script are available on GIT HUB so you can help me to create better version with
more integration with proxmox.

HOWTO INSTALL HYPERLEDGER FABRIC 1.1.0-rc1 ON UBUNTU 16.04.x + APPLICATION EXAMPLE.

Thank you to be here in my blog. This how to install Hyperledger Fabric 1.1.0-rc1 on Ubuntu 16.04.x. I saw many tutorials about this Solution but most of the time I failed to install successfully the Fabric (maybe I messed up something). Here is the way I found to achieve my goals. Let’s go.

1.       Following prerequisites are required to install the Fabric.

Latest version of cURL and dev libraries

Latest version of Docker & Docker compose (docker v1.12.x or higher)
Latest version of Go-Lang (Go - Programming Language)
Python v2.7
Node JS v6.x (Currently v7.x not supported)

You must be root for topics 2 to 6. After will create a user and at 6.1 will do “sudo” for the rest of the tutorial.

2.       Fisrt Update

$ apt update

3.       Install Curl

$ apt install curl

4.       Install libtool

$ apt-get install libltdl-dev

5.       Install latest docker and docker compose

$ apt-get install docker.io docker-compose

Chreck the version :

$ docker --version

$ docker-compose --version

6.       Install Go Language

$ sudo apt install golang-go

6.1   Create a User

$ useradd –m –c “Fabric DEV User”    yourusername

Put the current user in docker group

$ sudo usermod -a -G docker yourusername

$ sudo su - yourusername

Export the environment variables (put it in user bash profile):

$ vi

$ vi .bashrc

export GOPATH=$HOME/gopath

export PATH=$PATH:/usr/local/go/bin

to test it enter:

$ go

Go is a tool for managing Go source code.

Usage:

     go command [arguments]

The commands are:

     build       compile packages and dependencies

     clean       remove object files

     doc         show documentation for package or sy

etc.

7.       Installation of NODEJS

$ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -

$ sudo apt-get install -y nodejs

Note: Ensure nodejs version is 6.x

$ nodejs –v

Installing Node.js will also install NPM,
Upgrade the npm tool with the following command:

$ sudo npm install npm@3.10.10 -g

8 Install Python 2.7

Pyhton maybe already installed, if not do :

$ apt install python

Check version :

 $ python --version

8.       Hyperledger Fabric Installation

First , create folders for the fabric

$ mkdir -p $GOPATH/src/github.com/hyperledger/

$ cd $GOPATH/src/github.com/hyperledger/ 

Remove all previous images from docker :

$ docker rm -f $(docker ps -aq)

Second you must download the Fabric, it can take time depending of your connection speed

$ curl -sSL https://goo.gl/6wtTN5 | bash -s 1.1.0-rc1

You ‘ll find after download two folder “bin” and “config”

hypledge@vps520804:~/gopath/src/github.com/hyperledger$ ll

total 20

drwxrwxr-x  5 hypledge hypledge 4096 Mar 22 10:48 ./

drwxrwxr-x  3 hypledge hypledge 4096 Mar 21 23:32 ../

drwxrwxr-x  2 hypledge hypledge 4096 Mar  2 00:29 bin/

drwxrwxr-x  2 hypledge hypledge 4096 Mar  1 20:58 config/

Put in your path the following environnement variables. The fabric will need these binaries to work

You ‘ll find these files and more in bin folder:

- cryptogen
 - configtxgen
 - configtxlator
 - peer

Edit user bash profile “.bashrc”:

Replace  : export PATH=$PATH:/usr/local/go/bin

By

 export PATH=$PATH:/usr/local/go/bin:$HOME/gopath/src/github.com/hyperledger/bin

To see all images has been downloaded correctly enter:

hypledge@vps520804:~$ docker images

ok you are done with the fabric. Now let’s install the Fabric Sample.

$ cd $GOPATH/src/github.com/hyperledger/ 

$ git clone https://github.com/hyperledger/fabric-samples.git

$ cd fabric-samples

$ cd fabcar

$ ls

enrollAdmin.js  hfc-key-store  invoke.js  node_modules  package.json  query.js  registerUser.js  startFabric.sh

Now launch the fabric application sample :

$./startFabric

We need to install node SDK for Hyperledger so that we can run the node modules in this example

$ npm install

At end enter :

$ node enrollAdmin.js

$ node registerUser

Results :

if Node query failed ,do :

$ docker rm -f $(docker ps -aq)

And  after do a ./startFabric again

There few things to change in the script. Depending of you CSV file.

In the picture above I have 4 columns in my CSV file. So in the script shell you must

 fn=$(echo $LINE | awk -F ";" '{print $2}')
 ln=$(echo $LINE | awk -F ";" '{print $3}')

 CMD=$(zmprov createAccount $email password displayName "${fn} ${ln}" givenName "${fn}" sn "${ln}")
 $CMD
 echo -e "Done !\n"

 echo "Modifying $email password…";
 CMD1=$(zmprov sp $email changeme1)
 $CMD1

 CMD2=$(zmprov ma $email zimbraPasswordMustChange TRUE)
 $CMD2
 echo -e "Modifying password is OK !\n";

Simple useful vBScript : Search function and Create a folder

I have created this function to help my colleague for a problem. The goal
is to search and find a folder and finally create a folder inside. Simple but very useful
You can also modify to achieve your own goal.
It was tested on Windows 8.x , but must work on Windows 7 , Vista and XP, (Windows Server too)

CONFIGURATION DE SENDMAIL EN RELAIS SMTP sur CENTOS 5.x

Installez « sendmail » si ce n’est déjà fait.

Yum install sendmail

Sinon nous avons 2 fichiers à éditer :

Sendmail.mc et sendmail.cf

Editons « sendmail.mc » et ajouter les lignes suivantes :

Comme on peut le voir nous avons utilisé le port 26 pour envoyer nos mails cela est possible grâce à la deuxième ligne « define ». Si le serveur smtp de destination utilise le port 25 cette ligne peut être effacée.

En suite nos modifierons le fichier « sendmail.cf » :

Trouvez la ligne commençons par « DS » et ajoutons le serveur de mail qui nous serveur smtp :

La dernière étape est de redémarrer sendmail :

 

Maintenant un test !
