Most network configuration manuals still refer to ifconfig and route as the primary network configuration tools, but ifconfig is known to behave inadequately in modern network environments. They should be deprecated, but most distros still include them. Most network configuration systems make use of ifconfig and thus provide a limited feature set. The /etc/net project aims to support most modern network technologies, as it doesn't use ifconfig and allows a system administrator to make use of all iproute2 features, including traffic control.
iproute2 is usually shipped in a package called iproute or iproute2 and consists of several tools, of which the most important are ip and tc. ip controls IPv4 and IPv6 configuration and tc stands for traffic control. Both tools print detailed usage messages and are accompanied by a set of manpages.
How To Install Iproute2 Ubuntu
The iproute2 suite is a collection of utilities for networking and traffic control. . These tools communicate with the Linux kernel via the (rt)netlink interface, providing advanced features not available through the legacy net-tools commands 'ifconfig' and 'route'.
Once you have created your docker with ubuntu latest or any of version image and crated a ubuntu container, you have to run your ubuntu container and install the following for the basic networking command,
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get install is followed by one or more packages desired for installation or upgrading. Each package is a package name, not a fully qualified filename. All packages required by the package(s) specified for installation will also be retrieved and installed. The /etc/apt/sources.list file is used to locate the desired packages. If a hyphen is appended to the package name (with no intervening space), the identified package will be removed if it is installed. Similarly a plus sign can be used to designate a package to install. These latter features may be used to override decisions made by apt-get's conflict resolution system.

Without IP and Netplan, I had no network connection, so I went to download packages in hopes of getting back up and running.To get iproute2_5.15.0-1ubuntu2_amd64.deb I needed to also install:
Usually there is at least one installed software package called metapackage that ships little or no features on its own, but defines dependencies on everything you probably do not want automatically removed.
One way to get to the point you arrived at, is to remove the package ubuntu-minimal. Doing so is rarely advisable - but possible, should you truly have a valid reason to deviate from the system Canonical has designated as the minimal distribution. Install ubuntu-minimal (possibly also ubuntu-server) and have a closer look for other dependencies that are now (re)installed as a result.
To install a software package from the Extras Library, first confirm that the amazon-linux-extras repository is installed on your instance. Then, list the available software packages, enable the one you're looking for, and then install the package using yum.
Identifies the currently installed InfiniBand and Ethernet network adapters and automatically upgrades the firmwareNote: If you wish to perform a firmware upgrade using customized FW binaries, you can provide a path to the folder that contains the FW binary files, by running --fw-image-dir. Using this option, the FW version embedded in the MLNX_OFED package will be ignored.Example:
On Redhat and SLES distributions with errata kernel installed there is no need to use the mlnx_add_kernel_support.sh script. The regular installation can be performed and weak-updatesmechanismwill create symbolic links to the MLNX_OFED kernel modules.
On Ubuntu and Debian distributions drivers installation use Dynamic Kernel Module Support (DKMS) framework. Thus, the drivers' compilation will take place on the host during MLNX_OFED installation. Therefore, using "mlnx_add_kernel_support.sh" is irrelevant on Ubuntu and Debian distributions.
For your machine to be part of the InfiniBand/VPI fabric, a Subnet Manager must be running on one of the fabric nodes. At this point, Mellanox OFED for Linux has already installed the OpenSM Subnet Manager on your machine.
The DKMS (on Debian based OS) and the weak-modules (RedHat OS) mechanisms rebuild the initrd/initramfs for the respective kernel in order to add the MLNX_OFED drivers.When installing MLNX_OFED without DKMS support on Debian based OS, or without KMP support on RedHat or any other distribution, the initramfs will not be changed. Therefore, the inbox drivers may be loaded on boot. In this case, openibd service script will automatically unload them and load the new drivers that come with MLNX_OFED.
MLNX_OFED for Ubuntu should be installed with the following flags in chroot environment:./mlnxofedinstall --without-dkms --add-kernel-support --kernel --without-fw-update --forceFor example:./mlnxofedinstall --without-dkms --add-kernel-support --kernel 3.13.0-85-generic --without-fw-update --forceNote that the path to kernel sources (--kernel-sources) should be added if the sources are not in their default location.
In case your machine has the latest firmware, no firmware update will occur and the installation script will print at the end of installation a message similar to the following:Device #1:----------Device Type: ConnectX4Part Number: MCX456A-ECADescription: ConnectX-4 VPI adapter card; EDR IB (100Gb/s) and 100GbE; dual-port QSFP28; PCIe3.0 x16; ROHS R6PSID: MT_2190110032PCI Device Name: 0b:00.0Base MAC: 0000e41d2d5cf810Versions: Current AvailableFW 12.14.0114 12.14.0114Status: Up to date
Case A: If the installation script has performed a firmware update on your network adapter, you need to either restart the driver or reboot your system before the firmware update can take effect. Refer to the table below to find the appropriate action for your specific card.
After installation completion, information about the Mellanox OFED installation, such as prefix, kernel version, and installation parameters can be retrieved by running the command /etc/infiniband/info. Most of the Mellanox OFED components can be configured or reconfigured after the installation, by modifying the relevant configuration files. See the relevant chapters in this manual for details.The list of the modules that will be loaded automatically upon boot can be found in the /etc/infiniband/openib.conf file.
This type of installation is applicable to RedHat 7.1, 7.2, 7.3 and 7.4 operating systems and Kernel 4.13.As of version 4.2, MLNX_OFED supports Mellanox Innova IPsec EN adapter card that provides security acceleration for IPsec-enabled networks. For information on the usage of Innova IPsec, please refer to Mellanox Innova IPsec EN Adapter Card documentation on Mellanox official web (mellanox.com --> Products --> Adapters --> Smart Adapters --> Innova IPsec).
If you have an operating system different than RHEL or SLES, or you have installed a kernel that is not supported by default in MLNX_OFED, you can use the mlnx_add_kernel_support.sh script to build MLNX_OFED for your kernel.The script will automatically build the matching group RPM packages for your kernel so that you can still install MLNX_OFED via yum.Please note that the resulting MLNX_OFED repository will contain unsigned RPMs, therefore, you should set 'gpgcheck=0' in the repository configuration file.
As of MLNX_OFED v4.2, users can opt to install the driver with upstream rdma-core libraries instead of the legacy libraries embedded in MLNX_OFED package.In order to install the upstream rdma-core libraries, add --upstream-libs --dpdk flags to the mlnxofedinstall script run.Example:
DiSNI is a Java library for direct storage and networking access from user-space. It currently provides an RDMA interface to access remote memory, and an NVMf interface to access remote NVMe storage. The optional package installed as part of MLNX_OFED, contains the system-dependent part of DiSNI, and allows seamless use of DiSNI Java applications without any further installations. For more information, please visit: In order to install the libdisni package, add the --with-libdisni flag to the mlnxofedinstall script.
As of MLNX_OFED v4.5, NEO-Host users can opt to install the NEO-Host package embedded in MLNX_OFED package.In order to install NEO-Host, add the --with-neohost-backend flag to the mlnxofedinstall script run.Example:
In this article, I will take you through different iproute2 tools examples to manage Network Connections in Linux. You might have used tools from net-tools package to manage your kernel static routes and manage other Network related infrastructure but over the time it has become obsolete now since its development stopped long back and now there is a latest iproute2 package with new set of tools like ip command available to manage network connections in Linux. In this session, we will look into multiple examples and usages of iproute2 tools in Linux. 2ff7e9595c
