Configuration Bacula BAT in Ubuntu

Run in .../bacula-2.2.8/src/qt-console this file:

./build-depkgs-qt-console

then run in same directory:

make

Download qwt package for ubuntu:

qwt_5.0.1.orig.tar.gz

Unzip that and then under qwt-5.0.1.orig/qwt-5.0.1:

qmake

make

make install

add this line in user profile:

(for example for a user nemed UBUNTU => /home/ubuntu/.profile)


export LD_LIBRARY_PATH=/usr/local/qwt/lib:$LD_LIBRARY_PATH


Configure Bacula with option:
--with-qwt=/usr/local/qwt
--enable-bat

Copy BAT directory in /etc/bacula/:


cp -R /.../bacula-2.2.5/qt-console/ /etc/bacula/

Start BAT:

/etc/bacula/qt-console/bat -c /etc/bacula/bconsole.conf

Set up OpenVPN GUI on Windows XP

1. Download openvpn.se gui

http://openvpn.se/files/install_packages/
openvpn-2.0.9-gui-1.0.3-install.exe


(at the time of writing)

2. Click on the file for installation:
- Make sure you select or deselect these times

* deselect “AutoStart OpenVPN GUI”
* Select “My Certificate Wizard”
* Select “Hid the TAP-Win* Virtual Ethernet Adapter”

- Click Next or OK until installation is done

3. put “client.ovpn” in c:\Program Files\OpenVPN\config\

4. Copy these files from server to c:\program files\openvpn\config:
ca.crt
home.crt
home.key

5. Edit the client.ovpn:

remote my-server-1 1194

to :

remote 10.66.66.47 1194 (The IP for server)

and:

ca ca.crt
cert home.crt
key home.key

to:

ca C:\\Programme\\OpenVPN\\config\\ca.crt
cert C:\\Programme\\OpenVPN\\config\\home.crt
key C:\\Programme\\OpenVPN\\config\\home.key


6. run Openvpn-gui.

You should see the a small icon with two red spots / retangular shapes on the notification area (bottom right of your screen). If you put your mouse cursor over it, a small tool tip would pop up indicating “OpenVPN GUI”.

To connect to VPN server:
1. Right click on the mentioned icon
2. Select Connect

To disconnect from VPN server:
1. Right click on the mentioned icon
2. Select Disconnect

Install OPENVPN on Ubuntu

Install the necessary software

I am going to configure openVPN as routing and not as Bridge.

Enter these commands on both the server and the client.

apt-get install openvpn openssl rdate


Now on the server side issue these commands

cd /usr/share/doc/openvpn/examples/easy-rsa/
cp * /etc/openvpn -R
cd /etc/openvpn
. ./vars (Be carefull there is a blank between two points)
./clean-all
./build-ca

Now create the certificates for the server

./build-key-server server

Now create the certificate for the client site

./build-key home

you can call it anything, I called it home

you can create as many keys as you need from this point for as many clients as you want, once you have finished issue this command.

./build-dh

Configure the server side

cd /usr/share/doc/openvpn/examples/sample-config-files/
cp server.conf.gz /etc/openvpn/
cd /etc/openvpn/
gunzip server.conf.gz
vim server.conf

Look for these lines

ca ca.crt
cert server.crt
key server.key # This file should be kept secret
dh dh1024.pem

and change to these ones

ca /etc/openvpn/keys/ca.crt
cert /etc/openvpn/keys/server.crt
key /etc/openvpn/keys/server.key # This file should be kept secret
dh /etc/openvpn/keys/dh1024.pem

uncomment the client-to-client directive to enable clients to be able to connect to each others through the VPN, and not only to the server.

Here is my SERVER.CONF:

port 1194

;proto tcp
proto udp

dev tap
;dev tun

ca /etc/openvpn/keys/ca.crt
cert /etc/openvpn/keys/server.crt
key /etc/openvpn/keys/server.key # This file should be kept secret

dh /etc/openvpn/keys/dh1024.pem

server 10.8.0.0 255.255.255.0

ifconfig-pool-persist ipp.txt
client-to-client
;duplicate-cn

keepalive 10 120
comp-lzo

persist-key
persist-tun

status openvpn-status.log

verb 3


Configure the client

First you need to copy the certificates from the server to the client, be sure to make this in a secure way, either using scp or a USB Key in order to keep your files secure.

the needed files are:

ca.crt
home.crt
home.key (should be kept secret)

and they are in the server's directory /etc/openvpn/keys/

now you have copied all these files to the client open a console on the client and

cd /usr/share/doc/openvpn/examples/sample-config-files/
cp client.conf /etc/openvpn/
cd /etc/openvpn/
vi client.conf

Look for these lines

ca ca.crt
cert client.crt
key client.key
remote my-server-1 1194

and change them for these ones.

ca /etc/openvpn/keys/ca.crt
cert /etc/openvpn/keys/home.crt
key /etc/openvpn/keys/home.key
remote [the.ip.of.server] 1194
that is all, unless you have made some other changes on the server side, as for example change from UDP to TCP to the default port, so you will have to change that also on the client side.

Start the server

openvpn /etc/openvpn/server.conf

if everything goes ok, you should see something like this,

If you arrived to this point you have your VPN stablished.

Then, you need to make one machine (the remote machine you want to connect to) publically visible.
Go to that machine and connect to the Internet. Go to No-IP.com.

Open an account at No-IP (it's free). In the No-IP setup screens (on their web site),
set up the information for your machine (they call it a "host"). Give your host a name (such
as "MyOffice") and select an extension to be added after "No-IP".
If you selected ".biz", for example, your machine will have the public name "myoffice.no-ip.biz".
Since the name you choose must be unique, No-IP provides a number of different extensions;

keep trying until your name is approved.

Install ddclient and set it with No-IP account:

apt-get install ddclient
