This tool[19] is found under the Network & Internet tab in the Mageia Control Center labelled "Network Center"
When this tool is launched, a window opens listing all the networks configured on the computer, whatever their type (wired, wireless, satellite, etc.). When clicking on one of them, three or four buttons appear, depending on the network type, to allow you to look after the network, change its settings or connect/disconnect. This tool isn't intended to create a network, for this see Set up a new network interface (LAN, ISDN, ADSL, ...) in the same MCC tab.
In the screenshot below, given as example, we can see two networks, the
first one is wired and connected, recognizable by this icon 
(this one is not connected
) and the second section shows wireless
networks, not connected recognizable by this icon 
and this one 
if connected. For the other network types,
the colour code is always the same, green if connected and red if not
connected.
In the wireless part of the screen, you can also see all the detected networks, with the SSID, the Signal strengh, if they are encrypted (in red) or not (in green), and the Operating mode. Click on the chosen one and then either on , or . It is possible here to go from a network to another one. If a private network is selected, the Network Settings window (see below) will open and ask you for extra settings ( an encryption key in particular).
Click on to update the screen.
This button allows you to watch the network activity, downloads (toward the PC, in red) and uploads (toward the Internet, in green). The same screen is available by right clicking on the .
There is a tab for each network (here eth0 is the wired network, lo the local loopback and wlan0 the wireless network) and a tab connection which gives details about connection status.
Nota
At the bottom of the window is a title Traffic accounting, we will look at that in the next section.
A - For a wired network
It is possible to change all the settings given during network creation. Most of the time, checking will do, but in case of problems, manual configuration may give better results.
For a residential network, the IP address always looks like 192.168.0.x, Netmask is 255.255.255.0, and the Gateway and DNS servers are available from your providers website.
if checked this will count the traffic on a hourly, daily or monthly basis. The results are visible in the Network monitor detailed in the previous section. Once enabled, you may have to reconnect to the network.
Allow interface to be controlled by Network Manager:

B - For a wireless network
Only the items not already seen above are explained.
Operating mode:
Select Managed if the connection is via an access point, there is an ESSID detected. Select Ad-hoc if it is a peer to peer network. Select Master if your network card is used as the access point, your network card needs to support this mode.
Encryption mode and Encryption key:
If it is a private network, you need to know these settings.
WEP uses a password and is weaker than WPA which uses a passphrase. WPA Pre-Shared Key is also called WPA personal or WPA home. WPA Enterprise is not often used in private networks.
Allow access point roaming:
Roaming is a technology which enables allows computer to change its access point while remaining connected to the network.

If you have to use a proxy server to access to the internet, you can use this tool[22] to configure it. Your net administrator will give you the information you need. You can also specify some services which can be accessed without the proxy by exception.
From Wikipedia, on 2012-09-24, article Proxy server: In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource available from a different server. The proxy server evaluates the request as a way to simplify and control their complexity.
This is useful when you have a computer (3) which has Internet (2) access and is connected also to a local network (1). You can use computer (3) as a gateway to give that access to other workstations (5) and (6) in the local network (1). For this, the gateway must have two interfaces; the first one such as an ethernet card must be connected to the local network, and the second one (4) connected to the Internet (2).
The first step is to verify that the network and the access to Internet are set up, as documented in “Centre de xarxes”.
The wizard[23] offers successive steps which are shown below:
If the wizard does not detect at least two interfaces, it warns about this and asks to stop the network and configure the hardware.
specify the interface used for the Internet connection. The wizard automatically suggests one of the interfaces, but you should verify that what is proposed is correct.
specify which interface is used for the Lan access. The wizard also proposes one, check that this is correct.
The wizard proposes parameters for the Lan network, such as IP address, mask and domain name. Check that these parameters are compatible with the actual configuration. It is recommended that you accept these values.
specify if the computer has to be used as a DNS server. If yes, the wizard will check that
bindis installed. Otherwise, you have to specify the address of a DNS server.specify if the computer is to be used as a DHCP server. If yes, the wizard will check that
dhcp-serveris installed and offer to configure it, with start and end addresses in the DHCP range.specify if the computer is to be used as a proxy server. If yes, the wizard will check that
squidis installed and offer to configure it, with the address of the administrator (admin@mydomain.com), name of the proxy (myfirewall@mydomaincom), the port (3128) and the cache size (100 Mb).The last step allows you to check if the gateway machine is connected to printers and to share them.
You will be warned about the need to check the firewall if it is active.
If you have configured the gateway machine with DHCP, you only need to specify in the network configuration tool that you get an address automatically (using DHCP). The parameters will be obtained when connecting to the network. This method is valid whatever operating system the client is using.
If you must manually specify the network parameters, you must in particular specify the gateway by entering the IP-address of the machine acting as the gateway.
Each network interface of a Mageia system is initially configured with a fix set of parameters. This corresponds to what is expected by a user of a desktop computer, but may not be adequate when the system is moved between various network environments: having the system run in different network environments will require that multiple configurations co-exist for a given network device - otherwise the interface might need to be re-configured each time the network environment changes.
Linux provides support for multiple configurations of network devices as a standard feature. The notion of a "network profile" refers to a set of configurations of network devices, defined for a specific network environment. Each network profile has a name - the initial configuration that comes out of system generation has the name "default"; when a new profile is created, a name must be specified which is different from all already existing profile names.
Draknetprofile is a - very simple - component of the Mageia Control Center (MCC), it provides a Graphical User Interface (GUI) for managing profiles. This GUI allows to
switch between profiles - i.e. activate a target profile to become the "current profile",
create a new, additional profile,
delete a profile from the list of defined profiles.
Defining/modifying profiles concerns the entire Linux system and all its users. Running draknetprofile therefore requires root privileges. Normally, launching is achieved from within MCC (which already runs as root):
Figure 1: Mageia Control Center: Network & Internet tab
launch the MCC by hitting the MCC icon in one of the panels of your desktop,
select the "Network & Internet" tab,
hit "Manage different network profiles" in the "Personalize and Secure your network" Section (solid red contour in Figure 1).
Draknetprofile can also be launched by a command-line instruction from a terminal emulator with root privileges (this may be helpful when standard-output or error-output from draknetprofile needs to be consulted - for instance for debugging). Simply type:
draknetprofile |
After the launch, the main page of Draknetprofile will be displayed:
Figure 2: Management actions of Draknetprofile
The upper zone of the window contains the list of the names of all presently defined profiles. The bottom zone presents a series of buttons:
"Activate" ... establish the selected profile (top zone of the window) as the current profile (and save the properties of the old profile);
"New" ... create a new profile;
"Delete" ... delete the selected profile from the list of defined profiles;
"Quit" ... exit from Draknetprofile.
Before hitting the "Activate" or the "Delete" button, you have to select a profile from the list: select it by a left-button click on the name of the target profile.
Hitting the "New" button will launch an auxiliary window where you can type the name of the profile you want to create; this name must be different from any already existing profile. This profile will be created as a precise copy of the currently active profile and immediately activated as the current profile. You will probably then need to specify its properties (modify the automatically created configuration) in a second, independent action:
exit from Draknetprofile (hit the "Quit" button),
back in the "Network & Internet" tab, you select the tab "Set up a new network interface (...)" (marked with dashed red contour in Figure 1),
you then go through the steps for configuring the interface; they are similar to those you did for configuring the original interface during system generation - as documented in the Drakconnect manual.
The middle zone of the window is normally hidden, hit the "Advanced" button to make it visible. It should display the list of names of Draknetprofile "modules" (such as "network", "firewall", "urpmi"), each with a check-button next to the name; these check-buttons determine whether the properties controlled by that module are included into the profile or not.
In a system where several profiles are defined, an additional user interaction is required when the system boots: at the very end of the bootstrapping activities - just before the Desktop Environment starts - you will get a message like
Select network profile: (1) default (2)
roaming* |
Type 1 or 2 to select the "default", respectively the "roaming" profile, or carriage-return to select the profile that is marked with an asterisk (the profile that was active when the system had been shut down).
Presently (Mageia-5) there appears to be an intermittent problem: it happens that the system becomes unresponsive after soliciting the user to select a profile. The only way out of this situation is to launch another boot. This problem is under investigation.
This tool[24] allows to configure secure access to a remote network establishing a tunnel between the local workstation and the remote network. We discuss here only of the configuration on the workstation side. We assume that the remote network is already in operation, and that you have the connection information from the network administrator, like a .pcf configuration file .
First, select either Cisco VPN Concentrator or OpenVPN, depending on which protocol is used for your virtual private network.
Then give your connection a name.
At the next screen, provide the details for your VPN connection.
For Cisco VPN
For openvpn. The openvpn package and its dependencies will be installed the first time the tool is used.
Select the files that you received from the network administrator.
Advanced parameters:
The next screen asks for IP-address of the gateway.
When the parameters are set, you have the option of starting the VPN connection.
This VPN connection can be set to start automatically with a network connection. To do this, reconfigure the network connection to always connect to this VPN.
If some systems on your network grant you services, and have fixed IP-addresses, this tool[25] allows to specify a name to access them more easily. Then you can use that name instead of the IP-address.
With this button, you add the name for a new system. You will get a window to specify the IP-address, the host name for the system, and optionally an alias which can be used in the same way that the name is.
You can access the parameters of an entry previously defined. You get the same window.
