ifconfig and netstat are two popular network tools that are commonly used in Linux-based operating systems. These tools can be used to display information about network interfaces and network connections respectively. However, ifconfig and netstat are not installed by default on some Linux distributions, including RHEL 7.0, CentOS 7.0, and Oracle Linux 7.<\/p>\n
\r\n# ifconfig\r\n-bash: ifconfig: command not found\r\n<\/pre>\nIn this guide, we will show you how to install ifconfig and netstat on RHEL 7.0\/CentOS 7.0\/Oracle Linux 7.<\/p>\n
Step 1: Enable EPEL repository<\/h2>\n
The first step is to enable the EPEL (Extra Packages for Enterprise Linux) repository. This repository contains additional software packages that are not included in the base RHEL\/CentOS\/Oracle Linux distribution. To enable the EPEL repository, run the following command:<\/p>\n
\r\nsudo yum install epel-release\r\n<\/pre>\nStep 2: Install net-tools package<\/h2>\n
After enabling the EPEL repository, you can install the net-tools package, which includes both ifconfig and netstat, by running the following command:<\/p>\n
\r\nsudo yum install net-tools\r\n<\/pre>\n\r\n# yum install net-tools -y\r\nLoaded plugins: fastestmirror\r\nLoading mirror speeds from cached hostfile\r\n * base: centos.biz.net.id\r\n * extras: mirror.smartmedia.net.id\r\n * updates: centos.biz.net.id\r\nResolving Dependencies\r\n--> Running transaction check\r\n---> Package net-tools.x86_64 0:2.0-0.17.20131004git.el7 will be installed\r\n--> Finished Dependency Resolution\r\n\r\nDependencies Resolved\r\n\r\n====================================================================================================\r\n Package Arch Version Repository Size\r\n====================================================================================================\r\nInstalling:\r\n net-tools x86_64 2.0-0.17.20131004git.el7 base 304 k\r\n\r\nTransaction Summary\r\n====================================================================================================\r\nInstall 1 Package\r\n\r\nTotal download size: 304 k\r\nInstalled size: 917 k\r\nDownloading packages:\r\nwarning: \/var\/cache\/yum\/x86_64\/7\/base\/packages\/net-tools-2.0-0.17.20131004git.el7.x86_64.rpm: Header V3 RSA\/SHA256 Signature, key ID f4a80eb5: NOKEY\r\nPublic key for net-tools-2.0-0.17.20131004git.el7.x86_64.rpm is not installed\r\nnet-tools-2.0-0.17.20131004git.el7.x86_64.rpm | 304 kB 00:00:10\r\nRetrieving key from file:\/\/\/etc\/pki\/rpm-gpg\/RPM-GPG-KEY-CentOS-7\r\nImporting GPG key 0xF4A80EB5:\r\n Userid : \"CentOS-7 Key (CentOS 7 Official Signing Key)\"\r\n Fingerprint: 6341 ab27 53d7 8a78 a7c2 7bb1 24c6 a8a7 f4a8 0eb5\r\n Package : centos-release-7-0.1406.el7.centos.2.3.x86_64 (@anaconda)\r\n From : \/etc\/pki\/rpm-gpg\/RPM-GPG-KEY-CentOS-7\r\nRunning transaction check\r\nRunning transaction test\r\nTransaction test succeeded\r\nRunning transaction\r\n Installing : net-tools-2.0-0.17.20131004git.el7.x86_64 1\/1\r\n Verifying : net-tools-2.0-0.17.20131004git.el7.x86_64 1\/1\r\n\r\nInstalled:\r\n net-tools.x86_64 0:2.0-0.17.20131004git.el7\r\n\r\nComplete!\r\n<\/pre>\nStep 3: Verify installation<\/h2>\n
To verify that ifconfig and netstat have been installed successfully, you can run the following commands:<\/p>\n
\r\nifconfig\r\nnetstat -a\r\n<\/pre>\nThese commands should display information about network interfaces and network connections respectively. For example:<\/p>\n
1. ifconfig command:<\/p>\n
