#Install the Apache package (the name of the package is: '''httpd''').

#Using a text browser such as '''lynx ''' on vm1 go to http://localhost. You should get the "Fedora Apache Test Page" which indicates your web server is running on the local virtual machine.

#'''Copy ''' the '''index.html''' file to as '''index.php''' and modify it to contain:<br><source>Hello, this is a web page on vm1.youruserid.ops and the current time is <?php system("date"); ?>!</source>

<ol><li value="2">On your host machine, again refresh your in the web-browsermanually add '''/index.php'''. Notice that in a web browser the ''index.php'' file isn't treated as a default page and the contents don't contain the date, but instead are displaying the text in the php code you entered into the index.php file (refer to above code).</li>

<li>Install the '''php ''' package on your vm1 machine, and restart your webserver. NOTE: The php package comes with a working default Apache configuration so you don't need to enable it manually.</li><li>Refresh the webpage for in your web-browser on your host machine. You should now notice that you see the date instead of the call to the date command. Refresh your webpage several times to see how the time changes. This is simply a "trivial example" of dynamic web content does it does provide a simple demonstration of how scripting languages can be used to create more dynamic webpages.</li>

For security, it is important to allow access to general areas of your webpage, but also limit access to other sub-directories that contain other webpages or documents. Penetration Tester Testers or hackers may be able to navigate your file systems within your html directory to obtain unauthorised information.

# As the root user on your gateway/host, try to forward incoming http connections that arrive on your host to the web server on vm1. Use an iptables command something like this:<br><source>iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to 192.168.X.2</source>OR this (whichever works):<br><source>iptables -t nat -A PREROUTING -i *yourinterfaceexternalinterface* -p tcp --dport 80 -j DNAT --to 192.168.X.2</source> {{Admon/important |Do not save these rules|The PREROUTING rule above will redirect all HTTP requests to vm1. That will be a problem in the future when you run yum install or yum update, which downloads things over HTTP.}} 

# To test this setup you'll need to use another machine outside your own network. If you are using an SSD and VMWare, For this purpose you can simply use the windows host. If you are using a removable drive, ask a classmate on another PC to act as the partner. In either case, enter your host's external IP address in their browser's address window(machine running Vmware).# Have the partner external machine view both '''index.html''' and '''index.php'''

# Have your partner view View both files again.<br><br>You will now modify the settings on the web-server to prevent machines outside our network from accessing the private directory.<br><br>

This sets up separate rules and access permissions for that subdirectory. Your partner should no longer be able to access any pages in the private directory (or any sub-directories of it)from external machines, but your other internal machines (including your host) should still have access.

#When you start the MySQL service, check the system log file for instructions regarding how to set the root password. Even though we will '''not ''' configure our MySQL service to be '''accessible over the network''', it is accepted as a "best practice" configuring for network access for each MySQL installation.

#Refer Start the mariadb server, then refer to the log file (by running '''journalctl -xe''') to learn how to run the two commands in order to generate the appropriate passwords.<br><br>NOTE: Use a password you make up yourself, but do <u>not</u> generate a use your own secret password, since you will be storing that password in a plain text file for later reference.

# Modify the Directory statement for your '''private ''' directory to prevent any machine other than your vm1 from accessing it.

#Modify the '''index.php ''' page in your '''private ''' directory to match the code below. This will test that your web server can connect to the database (replace the <user> and <password> with values appropriate for your machine):<br><source>

<ol><li>Perform a search on the roundcube application in order to access the website.</li><li>Either Download the lastest '''Complete''' "zipped tarball" from their website from a direct link or use (https://roundcube.net/download/) using wget on the wget command to download directly from a download link (This part may take some effort depending on the Sourceforge website).</li>

<li>Change the ownership of the '''temp''' and '''logs''' directories so they belong to '''apache'''.</li><li>If you're not in Andrew's sections and you have SELinux enabled: This service needs to be able to write to several directories ('''temp''' and '''logs''') that SELinux prevents write access to. If you are in a section that has SELinux set to '''enforcing''', run the following commands to let it know that apache should be allowed to write to files in those directories.

</li>::NOTE:If your machine does not have the semage '''semanage''' command, use yum to install the '''policycoreutils-python ''' package.<li>You will also need to tell selinux to allow the webserver to open connections to the MTAs with <source>setsebool -P httpd_can_network_connect 1</source></li>

::* Go onto your host, open Firefox and on the address bar type "'''vm1.<yourSenecaID>.ops/webmail/installer"''', make sure your dns on host can resolve the web address. Alternatively, instead of "vm1.<yourSenecaID>.ops" you can input the ip address of your vm1, "'''192.168.X.2/webmail/installer"''', change X to your own IP octet.

::* On the next page, under the '''IMAP settings''' insert "'''vm3.<yourSenecaID>.ops" under the '''imap settingsin ''' default_host'''default_hostfield and ''' field and "143" ''' in '''default_port''' field. Insert "Under '''SMTP settings''' insert '''vm2.<yourSenecaID>.ops" under '''smtp settings''' in '''smtp_server''' field, and "'''25" ''' in '''smtp_port''' field. Ensure '''smtp_user/smtp_pass''' is '''empty''' and '''uncheck''' the "Use the current IMAP username and password for SMTP authentication" checkbox. ::* Under '''Database setup''' '''db_dsnw''', enter "localhost" as your database server, "roundcubemail" for database name. Put "roundcube" as Database user, and the password you set for the roundcube user when you configured that in the previous steps step for database password. Everything else can be left as default. ::* Click next Next to create the configuration file, then download it to your '''host'''. By default it will be saved under "'''~SenecaIDyourSenecaID/Downloads"'''. Transfer the files that file '''to vm1 ''' using '''scp ''' and place it inside '''/var/www/html/webmail/config ''' folder.

::* Finally Make sure your SMTP and IMAP servers are running, then finally test your configuration by sending email using your smtp server through test field provided by webmail installer, you should receive a test email sent by RoundCube. Test your IMAP settings by simply loging in with your SenecaID and vm3 password on the same webpage. ::* If everything works properly you can skip '''skip to''' step 109. *Remember you can edit the configuration file manually by editing "/var/www/html/webmail/config/config.inc.php".

::* '<source>$config['smtp_server']$config['smtp_serversmtp_user']= '';$config['::* smtp_pass'] = '';$config['default_host']'''::* '''$config['default_port']'''</source>

*Using a the Firefox webbrowser, navigate to '''vm1.<yourdomain>.ops/webmail ''' and login(using the username only).

{{Admon/important |Backup your VMs!|You MUST perform a '''full backup''' of ALL of your VMs whenever you complete your '''OPS335 labs''' or when working on your '''OPS335 assignments'''. You should be using the dump or rsync command, and you should use the Bash shell script that you were advised to create in order to backup all of your VMs.}}
