Reported: UTC by codyzapp. Show Obsolete 1 View All Add an attachment proposed patch, testcase, etc. Description codyzapp UTC i get this strange error at boot too. It basically tells me netmount could not start because net. For me its ypbind that tells me it can't start due to net.
Netifrc scripts now support modular networking scripts, which means support for new interface types and configuration modules can easily be added while keeping compatibility with existing ones. Modules load by default if the package they need is installed. If users specify a module here that doesn't have its package installed then they get an error stating which package they need to install.
Ideally, the modules setting is only used when two or more packages are installed that supply the same service and one needs to be preferred over the other. We provide two interface handlers presently: ifconfig and iproute2. Only one of these is needed to do any kind of network configuration.
Both are installed by default as part of the system profile. As both ifconfig and iproute2 do very similar things we allow their basic configuration to work with each other.
For example both the below code snippet work regardless of which module the user is using. This means that if there is a DHCP server running on the network, the user just has to tell each client to use DHCP and it sets up the network all by itself.
DHCP can be provided by dhclient, dhcpcd, or pump. Each DHCP module has its pros and cons - here is a quick run down:. If more than one DHCP client is installed, specify which one to use - otherwise we default to dhcpcd if available. The default is not to set any of them:. APIPA tries to find a free address in the range If no reply is found then we assign that address to the interface.
Bonding is used to increase network bandwidth or to improve resiliency in face of hardware failures. If a system has two network cards going to the same network, then the administrator can bond them together so the applications see just one interface but they really use both network cards. There are many ways to configure bonding. Some of them, such as the Remove the net. Bridging is used to join networks together. For example, a system may have a server that connects to the Internet via an ADSL modem and a wireless access card to enable other computers to connect to the Internet via the ADSL modem.
It is possible to create a bridge to join the two interfaces together. It is possible to change the MAC address of the interfaces through the network configuration file too. Tunneling does not require any additional software to be installed as the interface handler can do it. Virtual LAN is a group of network devices that behave as if they were connected to a single network segment - even though they may not be.
Wireless networking on Linux is usually pretty straightforward. There are three ways of configuring wifi: graphical clients, text-mode interfaces, and command-line interfaces. The easiest way is to use a graphical client once a desktop environment is installed.
Most graphical clients, such as NetworkManager , are pretty self-explanatory. They offer a handy point-and-click interface that gets users on a network in just a few seconds. Wireless can also be configured from the command line by editing a few configuration files. This takes a bit more time to setup, but it also requires the fewest packages to download and install.
Since the graphical clients are mostly self-explanatory with helpful screen shots at their home pages , we'll focus on the command line alternatives. The important thing to remember is that wireless networks are configured on a global basis and not an interface basis. Some wireless cards are deactivated by default. To activate them, please consult the hardware documentation.
Some of these cards can be unblocked using the rfkill application. If that is the case, use rfkill list to see the available cards and rfkill unblock INDEX to activate the wireless functionality. If not, then the wireless card might need to be unlocked through a button, switch or special key combination on the laptop.
The wireless tools project provides a generic way to configure basic wireless interfaces up to the WEP security level. While WEP is a weak security method it's still prevalent in the world.
Wireless tools configuration is controlled by a few main variables. The sample configuration file below should describe all that is needed. One thing to bear in mind is that no configuration means "connect to the strongest unencrypted Access Point" - wireless tools will always try and connect the system to something.
It is possible to add some extra options to fine-tune the AP selection, but these are not required. One way is to configure the system so it only connects to preferred APs. By default if everything configured has failed and wireless-tools can connect to an unencrypted Access Point then it will. The complete guide is found on the netifrc documentation at Gentoo's GitWeb site.
Although it's not necessary to explicitly configure it, here's an example to make use of DHCP on an interface. The first step in configuring netifrc is to get a list of the network interfaces present on the system.
This is possible a couple different ways:. Alternative 1: The ip command will list all available interfaces when given the link action. The above command output is a cropped example. On a typical system, more interfaces will be present. Be aware that most of them are no physical interfaces, but virtual ones used for a variety of purposes. In this example, eth0 and eth1 are physical "real" network interfaces.
They can be used for network connections outside the machine. In the description fields it can be seen that eth0 is up and running active while eth1 is down not active. Depending on the system, many interface names may be listed including: eno1 , enp2s0 , wlan0 , ethernet0 , wireless0 , etc. A system can have more than one interface connected to more than one network if the hardware is available.
Alternative 2: the ifconfig command can be used to get a comprehensive list of available interfaces. It also be an used to detect if there is byte-activity on the interfaces which helps determine connectivity:. For more information on ifconfig see the man page locally man ifconfig or online. Alternative 3: if dmesg is installed, a list of messages should be generated each time the system boots. Although the above method is better in practice, this approach can also be used to determine available network interfaces:.
For more information on the use of dmesg see the man page locally man dmesg or online.
