EX.NO:1 Establishing a Local Area Network

AIM

Objectives

To establish a local Area Network consisting of three personal computers running the Linux operating system, and a hub.

Physically connect computers

Configure IP addresses using ifconfig

Manipulate routing table using route

Background Reading

Knowledge of network addressing standards and Linux system administration relating to Local Area Networks is necessary for this lab. Online Linux documentation can be found at www.tldp.org . Specifically, read the man pages on ifconfig, route , traceroute and chkconfig.

Required Equipment

Three PCs (with Linux OS)

PC’s should be equipped with Network Interface Cards

One hub/switch

Cables

Exercises

Students will perform the following tasks and explain:

How they did them.

Why they were/weren’t successful.

What they observed.

____ Setup a physical LAN

First, determine which cables are necessary for the available hardware

Insert one end of the cable into the Hub/Switch and the other end of the cable into the host computer.

Connect all host computers to the Hub/Switch as in the figure below

192.168.1.1 192.168.1.2 192.168.1.3

HUB/Switch

To start the process of setting up a printer,

click System > Administration > Printing to bring up the Printer administration tool (see Figure 1).

From this window you need to click the Add button and select "Printer".

You will have to enter your root password to continue.

Depending upon the state of your firewall, this might open up a window informing you that changes must be made to your firewall to allow the detection of a network printer.

Allow this to happen by clicking Adjust Firewall.

You will then be asked for your root password once again.

The next window to appear is the New Printer window.

Here you will expand the Network Printer selection (see Figure 2) and then select Find Network Printer.

When you click that button you will need to enter the IP address of your printer server and then click the Find button.

Once you have done that the tool will automatically add the necessary information for the printer location

Click the Verify button to make sure the printer information is correct. In my case I had to replace the host name with the IP address.

I could have gotten around this by mapping the hostname to an IP address in the /etc/hosts file.

Once you have done this, click the Forward button and the drivers will automatically be detected and installed (if necessary).

If your drivers must be installed, click the Install button (when prompted). The drivers will then be attached to the printer and you will be moved to another screen - printer description.

The information in this window is all user-friendly, user-readable information.

After you fill this out, click Apply, enter your root password, and click Print Test Page when prompted.

That's it. You have successfully set up a networked printer in Linux.

____ Host set-up (e.g. IP address and netmask) using ifconfig

a. ifconfig command usage for this part of the lab will be to configure network interface devices. This includes adding the IP address and the netmask for the host.

b. Boot each host machine and log on with your user-name.

c. Open a new terminal on each host and log on as root.

$ su -

# password

d. Check network interface settings using ifconfig

# ifconfig –a

e. Verify that eth0 exists on each host by checking the output from above

f. Set the ethernet interface at each host using ifconfig

This will assign an ip address and network mask to the host. The following is a sample.

For host 1: # ifconfig eth0 192.168.1.1 netmask 255.255.255.0

g. Verify communication among the machines by using the ping command.

On host 1 ping the other two hosts.

# ping 192.168.1.2

--------output------

# ping 192.168.1.3

--------output------

On host A run traceroute to the other hosts

#traceroute 192.168.1.2

---------output---------

#traceroute 192.168.1.3

---------output---------

h. Changes using ifconfig at this point are not permanent and will be lost on reboot. To make the configuration effective on reboot you need to edit the file /etc/sysconfig/networks-scripts/ifcfg-eth0 to have the following settings.

# contents of ifcfg-eth0

DEVICE = eth0

BROADCAST = 192.168.1.255

IPADDR = 192.168.1.1

NETMASK = 255.255.255.0

NETWORK = 192.168.1.0

ONBOOT = yes

BOOTPROTO = none

i. Check that the network script has been added to the default init levels.

# chkconfig --list

j. If the network script is not on add it using chkconfig. This command adds the network script to the current run level.

# chkconfig --add network

____ Manipulate routing tables using route

a. The route command is used to look at the hosts routing table and can be used to add or delete routes from the table. It has the following syntax:

route add|del –net|-host target [gateway] [metric] [device]

route manipulates the kernel's IP routing table. Its primary use is to set up static routes to specific hosts or networks via an interface after it has been configured with the ifconfig command. The command route with no arguments displays the routing table.

b. After the steps from part 2 the route to the network 192.168.1.0 will be in the routing table. Verify the network is in the routing table using the route command.

# route

---output---

To illustrate the use and functionality of the command route, we will delete an entry and add an entry to the table. Delete the network 192.168.1.0 using the route command.

# route del –net 192.168.1.0 netmask 255.255.255.0

Check the routing table and verify that the network has been removed from the routing table.

# route

Verify the deleted network is no longer reachable.

# ping 192.168.1.3

Add individual hosts to the routing table to allow communication.

# route add –host 192.168.1.2 dev eth0

# route add –host 192.168.1.3 dev eth0

Verify these hosts are in the routing table.

# route

Use the ping command to verify communication among the machines has been restored.

# ping 192.168.1.2

# ping 192.168.1.3

Notice the machines were reachable when either the network or the individual host was in the routing table. Note also that the exercise manipulating the routing table was unnecessary since the ifconfig command places the network in the routing table for us.

Connect Internet in Linux Environment

Configuring networks such as a Digital Subscriber Line (DSL) or Asynchronous Digital Subscriber Line (ADSL) primarily used for accessing the internet can be a hassle, especially when you aren't using the same operating system as what the directions were originally written for. This article is a starting point for configuring DSL using Ubuntu Linux.

Steps

Open Network Connections to set up network settings in Ubuntu. Go to “System”, “Preferences” and chose “Network Connections."

Under the “Wired” tab, click on “Auto eth0” and select “Edit."

Click on “IPV4 Settings” tab. Chose the “Automatic (DHCP)” option if your network has a DHCP server. The DHCP Server has automatically assigned the IP address to your system. Click "Apply."

You also chose the “Manual” option from the Method drop-down list and assign the IP address, netmask and gateway manually. You'll also have to assign the DNS Server address. Click "Apply."

Check the IP address settings. Go to “Applications” “Accessories” and chose “Terminal."

Type the following command into terminal: “sudo ifconfig” without quotes.

Get your new addresses. The Ifconfig command will show the inet address, broadcast address and mask address.

Installation of Apache Web server and configuring for PHP support.

The installation procedure here is based on CentOS 6.x workstation default installation. This distro and installation lack many of the libraries you need so it requires more work to get XAMPP running than on other distros like Ubuntu.

1. The default installation of CentOS lacks some of the libraries that XAMPP needs to run, including 32 bit compatibility libraries. To get them you su to root then use this yum command

2. Download and install the latest verions from the XAMPP – 1.8.1 as of this writing – from the XAMPP download page.

3. Unpack the tarball.

4. Move the xampp package to /opt

5. XAMPP was designed to run on 32 bit operating systems. The start up script will prevent xampp from starting up if you are running on a 64 bit system which isn’t necessary since you installed 32 bit compatibility libraries in step 1. To get around this restriction, open /opt/lampp/lampp in an editor and comment out the following lines.

7. Open /opt/lampp/etc/etc/extra/httpd-xampp.conf in an editor.

8. Replace the “Deny from all” statement with “Require all grant” in the <LocationMatch> stanza. You can also comment out the “Allow from…” line if you don’t want to accept connections from any external system.

9. Start up xampp

10. Open http://localhost in a browser. You should a get a browser window with the XAMPP for Linux startup screen:

11. At this point most of the setup work for XAMPP is done. However, if you plan to use phpyMyAdmin you’ll have to do a little further configuration to get it to work properly.

12. XAMPP does not create all the tables that phpmyadmin needs so you have to do this with an SQL script that is enclosed with the package. To do this click on the Import tab in the toobar at the top of the screen.

13. Click on the Choose button in the File to import section. The button in your version of phpMyAdmin might say Browse.

14. Choose the create_tables.sql script in /opt/lampp/lampp/phpmyadmin/examples directory.

15. Click on the Go button in the Format of imported file to run the script which will add all the tables you need to the phpmyadmin database.

16. Open /opt/lampp/lampp/phpmyadmin/config.inc.php in your editor of choice.

18. Change the authentication type as follows:

19. Add the following lines in the config.inc.php file.

20. To set a root password for phpmyadmin click on the Users tab in the XAMPP Control Panel toolbar.

21. Click on the edit icon in the column to the right on the User Overview table for the root account on localhost.

22. Click on the Password radio button in the Change password section of the Edit Privileges: User ‘root’@'localhost’ page.

23. Enter the new password then re-type the password.

24. Click on the Go button to save the new password.

25. Repeat steps 21 – 24 for root account on linux.

26. Close your browser then restart Apache and MySQL in the XAMPP Control Panel.

EX.NO:3 B UPLOADINGWEB PAGE IN APACHE

You can upload files to an Apache Web server in two different ways: via a standalone File Transfer Protocolapplication or a Web-based control panel. Standalone FTP applications act as independent bridges connecting your computer and your Web server over an Internet connection. Launch them like you would any other application in your Windows programs directory. Web-based control panels provide a similar service, except you access them through your Web browser

Step 1

Open your computer’s FTP application. Certain versions of windows come bundled with an application called WS_FTP designed for this purpose. If you don’t already have an FTP application, download one. FileZilla is a free alternative to WS_FTP.

Step 2

Create a new connection in your FTP application and log in to your Apache server. What’s involved in creating a new connection varies depending on the FTP software you’re using. In FileZilla, open the Site Manager tool and click “New Site.” Enter your website’s Web address in the “Host” field. Enter your username and password. Click the “Connect” button when you’re finished.

Step 3

Navigate to the desired directory on your Apache server. In most FTP applications, your screen will be divided into two primary windows: one on the left showing files on your computer and another on the right showing files on your Web server. If you’re uploading files that you want to be visible to the public, look for a directory with a name like “Web,” “Public” or “public_html” in the window on the right side of your FTP application.

Step 4

Locate the files you would like to upload from your computer to your Web server. Double-click them in the left window to add them to your uploads queue. In FileZilla, the uploads queue is on the bottom of your screen. Each double-clicked file will appear in the queue. When the queue is empty again, your uploads are complete.

Step 1

Open your Web browser and navigate to your Web server’s control panel. The Web address of your control panel varies depending on your Web host. On Apache servers running cPanel, for example, your address will usually be www.yoursite.com/cpanel. Contact your Web host for the location of your control panel.

Step 2

Log in to your control panel and navigate to your file upload area. How this area is labeled depends on your Web host. Common labels include “FTP” and “Upload Files.” On servers running cPanel, the file upload area is usually called “File Manager.”

Step 3

Navigate to the Web server folder where you want to upload your files.

Step 4

Click the “Upload” button and select the files on your computer you’d like to upload. In cPanel, you’ll need to click a “Browse” button in File Manager to display files on your computer. Double-click files to add them to your queue. They will begin uploading automatically.

Objectives

To establish a local Area Network consisting of three personal computers running the Linux operating system, and a hub.

Physically connect computers

Configure IP addresses using ifconfig

Manipulate routing table using route

Background Reading

Required Equipment

Three PCs (with Linux OS)

PC’s should be equipped with Network Interface Cards

One hub/switch

Cables

Exercises

Students will perform the following tasks and explain:

How they did them.

Why they were/weren’t successful.

What they observed.

____ Setup a physical LAN

First, determine which cables are necessary for the available hardware

Insert one end of the cable into the Hub/Switch and the other end of the cable into the host computer.

Connect all host computers to the Hub/Switch as in the figure below

192.168.1.1 192.168.1.2 192.168.1.3

………………………………………………………………………………………………

____ Host set-up (e.g. IP address and netmask) using ifconfig

a. ifconfig command usage for this part of the lab will be to configure network interface devices. This includes adding the IP address and the netmask for the host.

b. Boot each host machine and log on with your user-name.

c. Open a new terminal on each host and log on as root.

$ su -

# password

d. Check network interface settings using ifconfig

# ifconfig –a

e. Verify that eth0 exists on each host by checking the output from above

f. Set the ethernet interface at each host using ifconfig

This will assign an ip address and network mask to the host. The following is a sample.

For host 1: # ifconfig eth0 192.168.1.1 netmask 255.255.255.0

g. Verify communication among the machines by using the ping command.

On host 1 ping the other two hosts.

# ping 192.168.1.2

--------output------

# ping 192.168.1.3

--------output------

On host A run traceroute to the other hosts

#traceroute 192.168.1.2

---------output---------

#traceroute 192.168.1.3

---------output---------

# contents of ifcfg-eth0

DEVICE = eth0

BROADCAST = 192.168.1.255

IPADDR = 192.168.1.1

NETMASK = 255.255.255.0

NETWORK = 192.168.1.0

ONBOOT = yes

BOOTPROTO = none

i. Check that the network script has been added to the default init levels.

# chkconfig --list

j. If the network script is not on add it using chkconfig. This command adds the network script to the current run level.

# chkconfig --add network

____ Manipulate routing tables using route

a. The route command is used to look at the hosts routing table and can be used to add or delete routes from the table. It has the following syntax:

route add|del –net|-host target [gateway] [metric] [device]

b. After the steps from part 2 the route to the network 192.168.1.0 will be in the routing table. Verify the network is in the routing table using the route command.

# route

---output---

To illustrate the use and functionality of the command route, we will delete an entry and add an entry to the table. Delete the network 192.168.1.0 using the route command.

# route del –net 192.168.1.0 netmask 255.255.255.0

Check the routing table and verify that the network has been removed from the routing table.

# route

Verify the deleted network is no longer reachable.

# ping 192.168.1.3

Add individual hosts to the routing table to allow communication.

# route add –host 192.168.1.2 dev eth0

# route add –host 192.168.1.3 dev eth0

Verify these hosts are in the routing table.

# route

Use the ping command to verify communication among the machines has been restored.

# ping 192.168.1.2

# ping 192.168.1.3
