Source of examples: How to do Linux Network Bonding. DEBUG: enable debugging when logging. If the pre-up command fails the network card activation wont take place. You can store all of it in the single file named interfaces, or as separate files in the directory interfaces. A typical IPv4 configuration from a portable device is shown below. A detailed explanation for the single commands is given below. The configuration for these interfaces looks as follows.
As the next step we will have a look at the single statements to configure a desired interface. At startup of your system the setup scripts go through the configuration files for the network interfaces.
The network interfaces are brought up in the order they are listed. If you aren't sure how to use it though, or if you installed the desktop manually and might not have brought it in, the following will likely be useful.
Ensure your user account is a member of the netdev group. Install the plasma-nm package. Restart your Plasma session most easily by logging out and logging back in. A new applet with a traditional "no Wi-Fi signal" icon will appear in the system tray.
Click this icon. Neighboring wireless networks with a broadcasted SSID should be listed: Click on the desired network's name. After providing, click the "Connect" button. The wireless network connection will be activated. If the desired network is not listed e. Tick "Use Encryption" if in use on the network. Select the encryption method used usually "WPA Personal". Click the "Connect" button to activate the wireless network connection.
In some desktops, such as KDE Plasma, a button to create a hotspot is visible in the network applet if two separate wireless network interfaces are present. It's an all-in-one wireless client, wireless daemon, and even a DHCP client optionally! It has virtually zero dependencies and uses modern kernel features as often as possible. First, install the iwd package. Edit this file with root permissions using your favorite editor. As per man iwd. This is usually fine with Cisco Switches, but eg.
Juniper switches use the RSTP costs and therefore this may lead to different spanning tree calculations and loop problems. This can be fixed by settings the costs manually, either on the switch or on the server.
Bridging without Switching By default the Linux bridge acts like a switch. This means, it remembers the MAC addresses behind a switch port and if the destination MAC address is known, data packets or only forward to the respective port - otherwise packets will be broadcasted. In some setups this is bad. For example if the bridge connects 2 trunk interfaces and the same MAC addresses may be seen from both interfaces, depending on the VLAN.
YYY, then there is no need to specify the vlan-raw-device, as the raw device can be retrieved from the interface name. Eg: auto eth0. Just config the bridge, and the VLAN interface will be created automatically when creating the bridge, e. Attaching the physical interface eth0 to a bridge eg. Kernel newer than 2. This is done using a post-up line in the bonding interface configuration. This is useful when more than one server is to be visible via the Internet.
Note that virtual hosts can support multiple Apache servers with a single IP address. Apache responds to the domain name supplied by the client in the HTTP header. In many other situations, one external IP is needed for each server using a port. The above configuration is the previous traditional method that reflects the traditional use of ifconfig to configure network devices.
Those types of virtual interfaces have names of the form interface:integer and ifconfig treats them very similarly to real interfaces. Nowadays ifupdown uses the ip utility from the iproute2 package instead of ifconfig.
The newer ip utility does not use the same concept of aliases or virtual interfaces. However, it supports assigning arbitrary names to the interfaces they're called labels. The key difference from the method described above is that all such sections are treated by ifupdown as just one interface, so user can't add or remove them individually.
Note however that this method is dangerous! A similar warning from another person exists in the history of this page.
