Netværkscenter

draknetcenter

This tool[19] is found under the Network & Internet tab in the Mageia Control Center labelled "Network Center"

Introduktion

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 Monitor, Configure or Connect. 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 Refresh to update the screen.

The Monitor button

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 Internet icon in the system tray -> Monitor Network.

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.

Bemærk

At the bottom of the window is a title Traffic accounting, we will look at that in the next section.

The Configure button

A - For a wired network

It is possible to change all the settings given during network creation. Most of the time, checking Automatic IP (BOOTP/DHCP) 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.

Enable traffic accounting 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.

Opsætning af et nyt netværksgrænseflade (LAN, ISDN, ADSL, ...)

drakconnect

Introduktion

This tool[20] allows to configure much of local network or Internet access. You have to know some information from your access provider or your network administrator.

Select the type of connection you want to set, according to which hardware and provider you have.

A new Wired connection (Ethernet)

  1. The first window lists the interfaces which are available. Select the one to configure.

  2. At this point, the choice is given between an automatic or a manual IP address.

  3. Automatic IP

    1. Ethernet/IP settings: you have to select if DNS servers are declared by the DHCP server or are manually specified, as explained below. In the last case, the IP address of DNS servers has to be set. The HOSTNAME of the computer can be specified here. If no HOSTNAME is specified, the name localhost.localdomain is attributed by default. The Hostname can also be provided by the DHCP server with the option Assign host name from DHCP server. Not all DHCP servers have such a function and if you're setting up your PC to get an IP address from a domestic ADSL router, it is unlikely.

    2. The advanced button give the opportunity to specify:

      • Search domain (not accessible, as provided by the DHCP server)

      • the DHCP client

      • DHCP timeout

      • Get YP server from DHCP (checked by default): specify the NIS server

      • Get NTPD server from DHCP (synchronisation of clocks)

      • the HOSTNAME required by DHCP. Only use this option if the DHCP server requires the client to specify a hostname before receiving an IP address. This option is not dealt by some DHCP servers.

    3. After accepting, the last steps which are common to all connection configurations are explained: “Ending the configuration”

  4. Manuel konfiguration

    1. Ethernet/IP settings: you need to declare what DNS servers to use. The HOSTNAME of the computer can be specified here. If no HOSTNAME is specified, the name localhost.localdomain is attributed by default.

      For a residential network, the IP address usually looks like 192.168.x.x, Netmask is 255.255.255.0, and the Gateway and DNS servers are available from your service provider's website.

      In advanced settings, you can specified a Search domain. It would usually be your home domain, i.e. if your computer is called "splash", and it's full domain name is "splash.boatanchor.net", the Search Domain would be "boatanchor.net". Unless you specifically need it, it's ok not to define this setting. Again, domestic ADSL would not need this setting.

    2. The next steps are exposed at “Ending the configuration”

In the last case, the IP address of DNS servers has to be set. The HOSTNAME of the computer can be specified here. If no HOSTNAME is specified, the name localhost.localdomain is attributed by default. The Hostname can also be provided by the DHCP server with the option Assign host name from DHCP server. Not all DHCP servers have such a function and if you're setting up your PC to get an IP address from a domestic ADSL router, it is unlikely.

    2. The advanced button give the opportunity to specify:

      • Search domain (not accessible, as provided by the DHCP server)

      • the DHCP client

      • Get NTPD server from DHCP (synchronisation of clocks)

      • the HOSTNAME required by DHCP. Only use this option if the DHCP server requires the client to specify a hostname before receiving an IP address. This option is not dealt by some DHCP servers.

    3. After accepting, the last steps which are common to all connection configurations are explained: “Ending the configuration”

  5. Manuel konfiguration

    1. Cable/IP settings: you need to declare what DNS servers to use. The HOSTNAME of the computer can be specified here. If no HOSTNAME is specified, the name localhost.localdomain is attributed by default.

Here, you can delete a network interface[21].

Click on the drop down menu, choose the one you want to remove and then click next.

You'll see a message that the network interface has been deleted successfully.

Proxy

drakproxy

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.

drakgw

Principles

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 “Netværkscenter”.

Gateway wizard

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 bind is 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-server is 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 squid is 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.

Configure the client

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.

Stop connection sharing

If you want to stop sharing the connection on the Mageia computer, launch the tool. It will offer to reconfigure the connection or to stop the sharing.

Configure VPN Connection to secure network access

drakvpn

Introduktion

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 .

Konfiguration

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.

Definition af værter

drakhosts

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.

Add

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.

Modify

You can access the parameters of an entry previously defined. You get the same window.
