Warreee: Basic authentication in PHP with CGI workaround

Because in our webserversetup PHP is installed as a common gateway interface (CGI) basic authentication will not work in its usual way.
There is however a workaround.
First add a .htaccess file with following code in it:
'''
<IfModule mod_rewrite.c>
RewriteEngine on \n
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
</IfModule>
'''

Next add the following line to your script right before the authentication:
'''
list($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) = explode(':' , base64_decode(substr($_SERVER['HTTP_AUTHORIZATION'], 6)));
'''

Now your script should work with basic authentication.

Setting up WordPress

2014-06-18T11:13:16Z

Warreee:

==Wordpress installeren gaat zeker gemakkelijk op onze servers==

Je downloadt het installatiebestand van de [http://wordpress.org wordpress-site].

Hierbij krijg je een gecomprimeerd bestand (.tar.gz of .zip) dit pak je uit.

Je krijgt dan een map met bestanden, deze bestanden (en dus niet de map) kopieer je via filezilla of een ander ftp programma naar je www-map op je shellaccount.

Hierna surf je naar je account, dus naar username.ulyssis.be, je krijgt hier een melding dat je je wp-config.php nog moet aanmaken, het gemakkelijkste is gewoon de wizard blijven volgen, klik dus op: ''Create a Configuration File''.

Daarna op ''Let's go!'' waarna je gegevens van je database gaat moeten invullen:

* '''Database Name: '''als je nog geen mysql database of user hebt aangemaakt op UCC dan moet je dat daar doen. De standaard database is dan: username_username.
* '''User Name: '''dit is de naam die je hebt opgegven tijdens het maken van je mysql account, vaak is deze hetzelfde als je gebruikersnaam bij ULYSSIS.
* '''Password: '''het wachtwoord dat je hebt opgegven bij de aanmaak van je mysql account
* '''Database Host: '''dit is <code>mysql.ulyssis.org</code>
* Het laatste veld verander je niet.

Vervolgens krijg je de volgende error: ''Sorry, but I can’t write the <code>wp-config.php</code> file.'' Maar geen paniek, de tekst die WordPress gemaakt heeft is hetgene wat we nodig hebben. Kopieer deze tekst, sla dit op in een bestand <code>wp-config.php</code>. Dit bestand zet je dan weer via Filezilla over naar je www-directory.

Klik hierna op ''Run The install.'' Hier kan je dan de laatste gegevens invullen.

Daarna zal de installatie zichzelf uitvoeren en voilà, je hebt wordpress geïnstalleerd.

==Setting up multiple instance of Wordpress==

If you want to have multiple instances of a Wordpress site then you the create a new folder in your homedir from you shell account. Then you make a new virtual host for this directory in UCC.

Name: alias.username.ulyssis.be
Document root: /home/user/username/new_folder

From now on you do al the same steps as for a regular wordpress installation.

Accessing shell servers over SSH

2014-05-10T11:14:08Z

Warreee: /* Useful commands */

Users can access the ULYSSIS servers through two machines: <code>ssh1.ulyssis.org</code> and <code>ssh2.ulyssis.org</code>. Both of them run Linux. You can run commands on these servers or use them to access the files on your ULYSSIS account. The servers can only be accessed trough SSH, not through FTP or any other protocol.

=Running commands=

To run a command on the shell servers, you will need to connect to them using a terminal. Our servers do not support a full graphical interface.

==Linux==

On Linux, you can just open a terminal and connect to the servers by using one of the following commands (with <code>username</code> your username):

<p><code>ssh username@ssh1.ulyssis.org</code></p>
<p><code>ssh username@ssh2.ulyssis.org</code></p>

<p>Enter your password and you're connected. </p>

<p>By doing this, the terminal will now act as a terminal on the remote server. To disconnect, type <code>logout</code>, <code>exit</code> or use Ctrl+D.</p>

==Windows==

Windows doesn't support native terminals, so you will have to download a program first. A good option is [http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Putty], which is completely free and doesn't require any installation. Just download it and run the .exe file. The parameters:
<ul>
<li>Host name: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Protocol: SSH</li>
<li>Port: 22 (should be set automatically)</li>
</ul>

<p>You can save these options for later on.</p>

<p>Next, you will be asked to give your password.</p>

<p>Doing all this will open a terminal to the remote server which can be used the same way as a Linux terminal. To disconnect, type <code>logout</code>, <code>exit</code> or use Ctrl+D.</p>

<p>More information about Putty can be found at http://the.earth.li/~sgtatham/putty/0.60/htmldoc/.

==Mac==

On Mac, you can just open Terminal.
This application can be found in the Utilities folder within your Application folder.
If you don't find it there, you can use Spotlight to find it.

You can now connect to the servers by using one of the following commands (with <code>username</code> your username):

<p><code>ssh username@ssh1.ulyssis.org</code></p>
<p><code>ssh username@ssh2.ulyssis.org</code></p>

<p>Enter your password and you're connected. </p>

<p>By doing this, the terminal will now act as a terminal on the remote server. To disconnect, type <code>logout</code>, <code>exit</code> or use ctrl+D.</p>

==Useful ideas==

Here are some useful ideas about what you could do with your shell server access:

Accessing your files

2014-05-10T11:09:52Z

Warreee: /* =Linux */

=Accessing your files=

Next to running commands, you can also use the shell servers to access your files. There are several methods to do this, some graphical, some not. The former definitely are the easiest option to go for.

On the server, your files are located in <code>/home/group/username/</code>. For a normal user with username <code>username/</code> this will be <code>/home/user/username/</code>, for an organisation with username <code>organisation/</code> this will be <code>/home/org/organisation/</code> etc.

==Graphical methods==

===Linux===

Linux normally gives you the option to connect to a server graphically. On Ubuntu, in the "Places" menu, choose "Connect to server." using the following options:
<ul>
<li>Service type: SSH</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave this blank</li>
<li>Folder: your home folder as described above (this is optional, this will save you clicking to your home folder)</li>
</ul>

This will open up a file browser connected to the remote server. Here, you can create new files, delete files, upload files (by copying or dragging them in the file browser), download files (by copying or dragging them from the file browser), change file rights etc.

===Windows===

Windows doesn't support native remote file browsers, so you will have to download a program first. A good option is [https://filezilla-project.org/ FileZilla], which is completely free. Download it, install it and run it. The parameters:
<ul>
<li>Dropdown menu: SFTP (SSH File Transfer Protocol)</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave the default value</li>
<li>Username: your username</li>
<li>Password: your password</li>
</ul>

===Mac===

Download the free and open source program [http://cyberduck.ch/ Cyberduck]

Follow the installations instructions and afterwards open Cyberduck in your Applications folder.
Click on 'Open Connection' in the left top corner.

<ul>
<li>Dropdown menu: SFTP (SSH File Transfer Protocol)</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave the default value</li>
<li>Username: your username</li>
<li>Password: your password</li>
</ul>

Click on 'Connect' and you're done.
By dragging and dropping you can manipulate files from and to your Mac.

==Non-graphical methods==

You can also use a terminal (on Linux) or Putty (on Windows) to access your files. Connect to the server as described above, and use commands as <code>cd</code>, <code>ls</code>, <code>mkdir</code>, <code>rm</code>, <code>nano</code> or <code>chmod</code> to manage your files.
You can also use <code>scp</code> (secure copy) to copy files from and to the servers (don't use <code>ssh</code> first). For example, to copy a file called <code>file.txt</code> to your home dir on the server, use (with <code>username</code> your username and <code>/home/user/username</code> your home dir as described above):

<code>scp file.txt username@ssh1.ulyssis.org:/home/user/username

<p>Next to running commands, you can also use the shell servers to access your files. There are several methods to do this, some graphical, some not. The former definitely are the easiest option to go for.</p>

<p>On the server, your files are located in <code>/home/group/username/</code>. For a normal user with username <code>username/</code> this will be <code>/home/user/username/</code>, for an organisation with username <code>organisation/</code> this will be <code>/home/org/organisation/</code> etc.</p>

<h3>Graphical methods</h3>

<h4> Linux </h4>

Linux normally gives you the option to connect to a server graphically. On Ubuntu, in the "Places" menu, choose "Connect to server." using the following options:
<ul>
<li>Service type: SSH</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave this blank</li>
<li>Folder: your home folder as described above (this is optional, this will save you clicking to your home folder)</li>
</ul>

This will open up a file browser connected to the remote server. Here, you can create new files, delete files, upload files (by copying or dragging them in the file browser), download files (by copying or dragging them from the file browser), change file rights etc.

<h4> Windows </h4>

Windows doesn't support native remote file browsers, so you will have to download a program first. A good option is [https://filezilla-project.org/ FileZilla], which is completely free. Download it, install it and run it. The parameters:
<ul>
<li>Dropdown menu: SFTP (SSH File Transfer Protocol)</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave the default value</li>
<li>Username: your username</li>
<li>Password: your password</li>
</ul>

<h4> Mac </h4>

Download the free and open source program [http://cyberduck.ch/ Cyberduck]

Follow the installations instructions and afterwards open Cyberduck in your Applications folder.
Click on 'Open Connection' in the left top corner.

<ul>
<li>Dropdown menu: SFTP (SSH File Transfer Protocol)</li>
<li>Server: ssh1.ulyssis.org or ssh2.ulyssis.org</li>
<li>Port: you can leave the default value</li>
<li>Username: your username</li>
<li>Password: your password</li>
</ul>

Click on 'Connect' and you're done.
By dragging and dropping you can manipulate files from and to your Mac.

<h3>Non-graphical methods</h3>

<p>You can also use a terminal (on Linux) or Putty (on Windows) to access your files. Connect to the server as described above, and use commands as <code>cd</code>, <code>ls</code>, <code>mkdir</code>, <code>rm</code>, <code>nano</code> or <code>chmod</code> to manage your files.
You can also use <code>scp</code> (secure copy) to copy files from and to the servers (don't use <code>ssh</code> first). For example, to copy a file called <code>file.txt</code> to your home dir on the server, use (with <code>username</code> your username and <code>/home/user/username</code> your home dir as described above): </p>

<code>scp file.txt username@ssh1.ulyssis.org:/home/user/username
</code>
