14 1 Triatmoko -
15 1 Triatmoko -
pjsua is an open source command line SIP user agent (softphone) that is used as the reference implementation for PJSIP, PJNATH, and PJMEDIA. Despite its simple command line appearance, it does pack many features!
16 1 Triatmoko -
17 29 Refik Hadzialic
This library is used for the SIP handler. More information about this library can be found on this web site http://www.pjsip.org/pjsua.htm

h3. SSH (installation required on both sides, server computer and BeagleBoard)
22 6 Triatmoko -
23 29 Refik Hadzialic
Secure Shell (SSH) is a network protocol for secure data communication, remote shell services or command execution and other secure network services between two networked computers that it connects via a secure channel over an insecure network: a server (running an SSH server program) and a client (running an SSH client program).[1].
24 6 Triatmoko -
25 29 Refik Hadzialic
Type the following to install it:
26 1 Triatmoko -
<pre>
27 1 Triatmoko -
sudo apt-get install ssh

We need to configure the ssh connections to the nanoBTS controller boxes without typing the password. We can achieve this by copying the public key to the nanoBTS boxes.
31 29 Refik Hadzialic
32 29 Refik Hadzialic
One has to create first the private and public keys on the local machine(i.e. server computer, where the test software runs):
33 29 Refik Hadzialic
<pre>
34 29 Refik Hadzialic
refik@ubuntu:$ [Note: You are on local-host here]
35 29 Refik Hadzialic
36 29 Refik Hadzialic
refik@ubuntu:$ ssh-keygen
37 29 Refik Hadzialic
Generating public/private rsa key pair.
38 29 Refik Hadzialic
Enter file in which to save the key (/home/refik/.ssh/id_rsa):[Enter key]
39 29 Refik Hadzialic
Enter passphrase (empty for no passphrase): [Press enter key]
40 29 Refik Hadzialic
Enter same passphrase again: [Press enter key]
41 29 Refik Hadzialic
Your identification has been saved in /home/refik/.ssh/id_rsa.
42 29 Refik Hadzialic
Your public key has been saved in /home/refik/.ssh/id_rsa.pub.
43 29 Refik Hadzialic
The key fingerprint is:
44 29 Refik Hadzialic
33:b3:fe:af:95:95:18:11:31:d5:de:96:2f:f2:35:f9 refik@ubuntu
45 29 Refik Hadzialic
</pre>
46 29 Refik Hadzialic
47 29 Refik Hadzialic
Then one needs to copy the public key to the remote machine (nanoBTS controller, i.e. BeagleBoard) using ssh-copy-id:
48 29 Refik Hadzialic
49 29 Refik Hadzialic
<pre>
50 29 Refik Hadzialic
refik@ubuntu:$ ssh-copy-id -i ~/.ssh/id_rsa.pub remote-host
51 29 Refik Hadzialic
refik@remote-host's password:
52 29 Refik Hadzialic
Now try logging into the machine, with "ssh 'remote-host'", and check in:
53 29 Refik Hadzialic
54 29 Refik Hadzialic
.ssh/authorized_keys
55 29 Refik Hadzialic
56 29 Refik Hadzialic
to make sure we haven't added extra keys that you weren't expecting. 
57 29 Refik Hadzialic
</pre>
58 29 Refik Hadzialic
59 29 Refik Hadzialic
After we have created the public and private keys, and coppied the public key on the machine to which we want to connect, we can test if we can make an SSH connection to the remote machine:
60 29 Refik Hadzialic
<pre>
61 29 Refik Hadzialic
refik@ubuntu:$ ssh remote-host
62 29 Refik Hadzialic
[Note: SSH did not ask for password.]
63 29 Refik Hadzialic
64 29 Refik Hadzialic
refik@remote-host:$ [Note: You are on remote-host here]

h3. Setproctitle (installation required only on server computer)
78 3 Triatmoko -
79 5 Triatmoko -
The library allows a process to change its title (as displayed by system tools such as ps and top).
80 1 Triatmoko -
81 30 Refik Hadzialic
Changing the title is mostly useful in multi-process systems, for example when a master process is forked: changing the children's title allows to identify the task each process is busy with.
82 5 Triatmoko -
83 30 Refik Hadzialic
You can use easy_install (i.e. the module we previously installed) to install the module. To perform a system-wide installation use:
84 30 Refik Hadzialic
Preferred installation procedure:
85 5 Triatmoko -
<pre>
86 1 Triatmoko -
sudo easy_install setproctitle
87 5 Triatmoko -
</pre>
88 5 Triatmoko -
89 30 Refik Hadzialic
Not preferred installation procedure:
90 5 Triatmoko -
If you are an unprivileged user or you want to limit installation to a local environment, you can use the command:
91 5 Triatmoko -
<pre>
92 1 Triatmoko -
easy_install -d /target/path setproctitle
93 5 Triatmoko -
</pre>
94 5 Triatmoko -
Notice that easy_install requires /target/path to be in your PYTHONPATH.

h3. Serial port library (installation required on both sides, server computer and BeagleBoard)
99 1 Triatmoko -
100 10 Triatmoko -
The serial port library is required for the cell phones to communicate with our software. The required library for Python can be installed by typing the following command (both on the server computer and the nanoBTS controller boxes i.e. BeagleBoards):
101 1 Triatmoko -
102 1 Triatmoko -
<pre>
103 1 Triatmoko -
sudo apt-get install python-serial

h3. MySQL Database (installation required only on server computer)
107 1 Triatmoko -
108 31 Refik Hadzialic
MySQL is a fast, multi-threaded, multi-user, and robust SQL database server. It is intended for mission-critical, heavy-load production systems as well as for embedding into mass-deployed software.
109 31 Refik Hadzialic
110 31 Refik Hadzialic
To install MySQL, run the following command from a terminal prompt:
111 31 Refik Hadzialic
<pre>
112 31 Refik Hadzialic
sudo apt-get install mysql-server
113 31 Refik Hadzialic
</pre>
114 31 Refik Hadzialic
115 31 Refik Hadzialic
During the installation process you will be prompted to enter a password for the MySQL root user.
116 31 Refik Hadzialic
117 31 Refik Hadzialic
Once the installation is complete, the MySQL server should be started automatically. More information can be found at: https://help.ubuntu.com/11.04/serverguide/C/mysql.html
118 31 Refik Hadzialic
119 31 Refik Hadzialic
h3. MySQLdb (installation required only on server computer)
120 31 Refik Hadzialic
121 1 Triatmoko -
MySQLdb is an thread-compatible interface to the popular MySQL database server that provides the Python database API.
122 1 Triatmoko -
 _mysql is a low-level API similiar to the MySQL C API. ZMySQLDA is a Database Adapter for Zope2.
123 7 Triatmoko -
124 1 Triatmoko -
If you want to write applications which are portable across databases, use MySQLdb, and avoid using this module directly. _mysql provides an interface which mostly implements the MySQL C API. For more information, see the MySQL documentation. The documentation for this module is intentionally weak because you probably should use the higher-level MySQLdb module. If you really need it, use the standard MySQL docs and transliterate as necessary.
125 7 Triatmoko -
126 31 Refik Hadzialic
<pre>
127 31 Refik Hadzialic
sudo apt-get install python-mysqldb

h3. pChart library 
131 31 Refik Hadzialic
132 8 Triatmoko -
The pChart library is within our installation les and does not require to be installed individually. The library is only required if one uses the web interface and requires the generated resulting image. The library is open source and does not require any licensing. However, if one needs to learn how the library works, information can be found on the pChart web page http://www.pchart.net/

134 33 Refik Hadzialic
h3. PhpMyadmin (installation required only on server computer)
135 8 Triatmoko -
136 8 Triatmoko -
phpMyAdmin is a very famous MySQL mangement software package. To use it you should install and configure PHP, Apache and php mysql.
137 8 Triatmoko -
The easy way to install PhpMyadmin is installing from package using Apt-get command.
138 8 Triatmoko -

244 23 Refik Hadzialic
h2. HTTPS
245 22 Refik Hadzialic
246 22 Refik Hadzialic
First we want to generate a server key by typing the following command:
247 22 Refik Hadzialic
<pre>
248 23 Refik Hadzialic
openssl genrsa −des3 −out server.key 4096
249 23 Refik Hadzialic
</pre>
250 23 Refik Hadzialic
251 23 Refik Hadzialic
252 23 Refik Hadzialic
This will generate a 4096 bit long private server key, one is asked to enter two times a password for the _server.key_. Using the generated private server key, we will create a certificate signing request, _server.csr_. We were prompted with a series of questions like country, state, organization name and etc which we had to enter to resume.
253 23 Refik Hadzialic
254 23 Refik Hadzialic
<pre>
255 22 Refik Hadzialic
openssl req -new -key server.key -out server.csr 
256 24 Refik Hadzialic
</pre>
257 24 Refik Hadzialic
258 24 Refik Hadzialic
In the next step we had to sign the certificate signing request and enter the amount of days for how long it should be valid. In our case we entered the duration of one year, one can make it for longer periods as well (i.e. the amount of 365 has to be changed).
259 24 Refik Hadzialic
260 24 Refik Hadzialic
<pre>
261 24 Refik Hadzialic
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
262 24 Refik Hadzialic
</pre>
263 24 Refik Hadzialic
264 24 Refik Hadzialic
We were asked to enter the password again for _server.key_. After we have completed this step we had to make a version of the _server.key_ which did not require a password, _server.key.insecure_ and we will rename the files appropriately. 
265 24 Refik Hadzialic
266 24 Refik Hadzialic
<pre>
267 24 Refik Hadzialic
openssl rsa -in server.key -out server.key.insecure
268 24 Refik Hadzialic
mv server.key server.key.secure
269 24 Refik Hadzialic
mv server.key.insecure server.key
270 24 Refik Hadzialic
</pre>
271 24 Refik Hadzialic
272 25 Refik Hadzialic
The generated files are very sensitive, since they are our keys. After these steps were completed, we had generated 4 files: _server.crt_, _server.csr_, _server.key_ and _server.key.secure_. Now we need to enable the SSL engine on the Apache web server. We copied _server.key_ and _server.crt_ into _/etc/appache2/ssl_. 
273 25 Refik Hadzialic
274 25 Refik Hadzialic
<pre>
275 25 Refik Hadzialic
refik@ubuntu:/etc/apache2$ sudo mkdir ssl
276 25 Refik Hadzialic
cp server.key /etc/apache2/ssl
277 25 Refik Hadzialic
cp server.crt /etc/apache2/ssl
278 25 Refik Hadzialic
</pre>
279 25 Refik Hadzialic
280 25 Refik Hadzialic
Then we enabled SSL by typing in _a2enmod ssl_, "it is simply a general purpose utility to establish a symlink between a module in _/etc/apache2/mods-available_ to _/etc/apache2/mods-enabled_ (or give a message to the effect that a given module does not exist or that it is already symlink-ed for loading)".
281 25 Refik Hadzialic
282 25 Refik Hadzialic
<pre>
283 25 Refik Hadzialic
refik@ubuntu:/etc/apache2/ssl$ sudo a2enmod ssl
284 25 Refik Hadzialic
Enabling module ssl.
285 25 Refik Hadzialic
See /usr/share/doc/apache2.2-common/README.Debian.gz on how to configure SSL and create self-signed certificates.
286 25 Refik Hadzialic
Run '/etc/init.d/apache2 restart' to activate new configuration!
287 26 Refik Hadzialic
</pre>
288 26 Refik Hadzialic
289 26 Refik Hadzialic
In the next procedure we had to establish a symlink from the 'available' default-ssl file to the 'enabled' file. Then we created a folder where our secured PHP files will be located (e.g. https://some-domain-name.com/test-software).
290 26 Refik Hadzialic
291 26 Refik Hadzialic
<pre>
292 26 Refik Hadzialic
refik@ubuntu:/etc/apache2/ssl$ sudo ln -s /etc/apache2/sites-available/default-ssl /etc/apache2/sites-enabled/000-default-ssl 
293 26 Refik Hadzialic
refik@ubuntu:/etc/apache2/ssl$ cd /var/
294 26 Refik Hadzialic
refik@ubuntu:/var$ sudo mkdir www-ssl
295 26 Refik Hadzialic
</pre>
296 26 Refik Hadzialic
297 26 Refik Hadzialic
We had backed up our old configuration files for the virtual hosts, for the case if we damage the Apache configuration files. Then we edited the _default-ssl_ file.
298 26 Refik Hadzialic
299 26 Refik Hadzialic
<pre>
300 26 Refik Hadzialic

Only the beginning of the file is listed here and we have modified the line starting with _DocumentRoot_ and _<Directory /var/www/>_ from _DocumentRoot /var/www_ to _DocumentRoot /var/www-ssl_ and from _<Directory /var/www/>_ to _<Directory /var/www-ssl/>_ (i.e. we had to redefine the location of our SSL directory).

One should keep in mind that the port 443 should be free for Apache to use it. In the proceeding step we had to ensure that Apache listens on the given port for a _https_ connection. One could test that by going into the _/etc/apache2/ports.conf_.

331 27 Refik Hadzialic
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl

    # to <VirtualHost *:443>

338 27 Refik Hadzialic
339 27 Refik Hadzialic
In our case it was set up correctly, since the command: _Listen 443_ was present. In our last configuration step we had to edit _default-ssl_ file to define the correct locations of our keys and to ensure the SSL engine was turned on.

The following part of the file had to be found and modified according to our key path locations:

       #   If both key and certificate are stored in the same file, only the

       #   SSLCertificateFile directive is needed.
354 27 Refik Hadzialic
       SSLCertificateFile    /etc/apache2/ssl/server.crt
355 27 Refik Hadzialic
       SSLCertificateKeyFile /etc/apache2/ssl/server.key

Finally we had configured our server and can proceed with the restart of the apache web server. We created a test web site _/var/www-ssl/index.php_ and navigated our browser to _https://localhost_. The test was successful!

h2. Configuring the password protection for the web site (using .htaccess)
371 28 Refik Hadzialic
372 28 Refik Hadzialic
However, to enable the use of Apache _.htaccess_ files, we will have to reconfigure the Apache configuration files again. _root_ access will be required. First we have to edit the _/etc/apache2/sites-available/default-ssl_ file. Find the following lines and modify the _AllowOverride None_ to _AllowOverride All_
373 28 Refik Hadzialic
like in the given configuration segment:
374 28 Refik Hadzialic
375 28 Refik Hadzialic
<pre>
376 28 Refik Hadzialic
        <Directory /var/www-ssl/>
377 28 Refik Hadzialic
                Options Indexes FollowSymLinks MultiViews
378 28 Refik Hadzialic
                AllowOverride All
379 28 Refik Hadzialic
                Order allow,deny
380 28 Refik Hadzialic
                allow from all
381 28 Refik Hadzialic
        </Directory>
382 28 Refik Hadzialic
</pre>
383 28 Refik Hadzialic
384 28 Refik Hadzialic
This will tell Apache web server that it is okay to allow _.htaccess_ files to over-ride previous directives. We must reload the Apache web server before the changes can take effect. We can do it by typing:
385 28 Refik Hadzialic
386 28 Refik Hadzialic
<pre>
387 28 Refik Hadzialic
sudo /etc/init.d/apache2 reload
388 28 Refik Hadzialic
</pre>
389 28 Refik Hadzialic
390 28 Refik Hadzialic
The next step is to go to the directory where our test software web page is located (e.g. _/var/www-ssl/testsoftware_) and to create a file called _.htaccess_.
391 28 Refik Hadzialic
Please insert the following code segment inside the created _.htaccess_ file where _/var/www-ssl/testsoftware/.htpasswd_ is your full path address to _.htpasswd_:
392 28 Refik Hadzialic
393 28 Refik Hadzialic
<pre>
394 28 Refik Hadzialic
AuthUserFile /var/www-ssl/testsoftware/.htpasswd
395 28 Refik Hadzialic
AuthName "Authorization Required"
396 28 Refik Hadzialic
AuthType Basic
397 28 Refik Hadzialic
require valid-user 
398 28 Refik Hadzialic
</pre>
399 28 Refik Hadzialic
400 28 Refik Hadzialic
Then in the next step, create another file called _.htpasswd_. After you have created it, we will add the usernames that should have access to the web site. We do that by typing the following command, where you can replace _konrad_ with any other combination of letters which will represent your username:
401 28 Refik Hadzialic
402 28 Refik Hadzialic
<pre>
403 28 Refik Hadzialic
refik@ubuntu:/var/www-ssl/testsoftware$ sudo htpasswd -c .htpasswd konrad
404 28 Refik Hadzialic
</pre>
405 28 Refik Hadzialic
406 28 Refik Hadzialic
Afterwards, you will be required to type twice the same password for the username you want to create, in this case _konrad_. "The -c flag is used only when you 
407 28 Refik Hadzialic
are creating a new file. After the first time, you will omit the -c flag, when you are adding new users to an already-existing password file. Otherwise you will overwrite the file!". You can add as many users as you wish, do not forget to remove the -c flag when you do it. In the last step, we have to modify the _/etc/apache2/apache2.conf_ file and to add at the end of it the following code segment where _/vaw/www-ssl/testsoftware_ is the full path to your web page directory where you put the _.htpasswd_ file:
408 28 Refik Hadzialic
409 28 Refik Hadzialic
<pre>
410 28 Refik Hadzialic
<Directory /vaw/www-ssl/testsoftware>
411 28 Refik Hadzialic
AllowOverride All
412 28 Refik Hadzialic
</Directory>
413 28 Refik Hadzialic
</pre>
414 28 Refik Hadzialic
415 28 Refik Hadzialic
We are done with editing. All we have to do now is to restart the Apache web server. We
416 28 Refik Hadzialic
can do that by typing:
417 28 Refik Hadzialic
418 28 Refik Hadzialic
<pre>
419 28 Refik Hadzialic
sudo /etc/init.d/apache2 restart
420 28 Refik Hadzialic
</pre>
421 28 Refik Hadzialic
422 1 Triatmoko -
You can test it now by opening a new browser tab and navigating to _https://localhost/testsoftware_ (keep in mind to replace _testsoftware_ with your name of the folder where the web page is located). If you configured everything properly, you should get a dialog where you can enter your created username and password and try to login.
