5.7.1:     Internet access

Wired

MEPIS Linux 7.0 typically picks up wired internet access upon boot without much problem.

Ethernet and cable

MEPIS Linux 7.0 comes preconfigured for a standard LAN (Local Area Network) that uses DHCP (Dynamic Host Configuration Protocol) to assign IP addresses and DNS (Domaine Name System) resolution. This will work in most cases as-is. You can change the configuration with the MEPIS Network Assistant (see Section 5.4).

When you boot MEPIS Linux 7.0, your network adapters are assigned a short interface name by udev, the kernel's device manager. For normal wired adapters this is usually eth0 (with subsequent adapters eth1, eth2, eth3, etc). Wireless adapters often come up on the eth0 interface in MEPIS Linux 7.0, but the interface name depends on the adapter's chipset. For instance, atheros cards often show up as ath0, while ralink usb adapters will be rausb0. To find out what interfaces have been detected and named in your system, click KMenu --> System --> Info Center --> Network Interfaces. For more details, open a terminal, become root, and enter:

ifconfig -a

Cable connections are routinely similar to ethernet in that you should only have to plug your cable modem directly to the NIC (Network Interface Card) in your PC. Most cable connections send DHCP information for automatic configuration of your PC.

It is highly recommended that you have a firewall (see Section 8.1) running if you are connecting directly to the Internet with your PC! If you are running a standalone/external firewall, most of which will run DHCP by default, simply connect to the router/hub/switch and your machine should autoconfigure via DHCP.

ADSL or PPPoE

If you use ADSL or PPPoE, connecting to the internet is relatively easy. Click Kmenu --> Internet --> Connection --> ADSL/PPPoE configuration, supply the root password, and follow the different screens, where you will be asked for some ISP information (like your username and password). Complete that section and you will be surfing the Internet a few seconds later.

Dialup

If you use a dialup connection with your computer, you will use KPPP. Click KMenu --> Internet --> Connection --> Internet Dialup Tool (KPPP) to define a connection, test that the modem is working, and dial your ISP.

On the Device tab you will need to set up the serial information. These are the equivalents of the COM ports under DOS-Windows:

For configuration details, see the KPPP Handbook in Links and Guides.

Wireless

MEPIS Linux comes preconfigured to autodetect a WiFi card, and in most cases your card will be automatically detected. If not, you should proceed to this page: Basic steps for enabling wireless.

There are three ways wireless can be supported in MEPIS Linux 7.0:

For more information about Ndiswrapper and Linuxant, see Links and Guides below.

Wireless cards can be either internal or external.

NOTE: The successful method varies for users because of the complicated interactions among the Linux kernel, wireless tools, and the local wireless card chipset and router.

Command line utilities

Command line utilities are useful for seeing detailed information, and are also commonly used in troubleshooting. Most must be run as root.


Troubleshooting

Ethernet cards in MEPIS Linux are configured in the file /etc/network/interfaces. The file is actually very simple in format and syntax, and not hard to edit in the event that other tools fail. See documentation by typing "man:interfaces" into the address bar of Konqueror.
