Question :
I have just setup on RHEL 7.0/CentOS 7.0/Oracle Linux 7 minimal server installation but i notice ifconfig and netstat command not found. How to make those command available ?
Solution :
By default, ifconfig and netstat utility is not installed on RHEL 7.0/CentOS 7.0/Oracle Linux 7 minimal server installation. You need to install net-tools utility manually, this include ifconfig and netstat command.
# ifconfig -bash: ifconfig: command not found
1. Run installation command :
# yum install net-tools -y Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: centos.biz.net.id * extras: mirror.smartmedia.net.id * updates: centos.biz.net.id Resolving Dependencies --> Running transaction check ---> Package net-tools.x86_64 0:2.0-0.17.20131004git.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================== Package Arch Version Repository Size ==================================================================================================== Installing: net-tools x86_64 2.0-0.17.20131004git.el7 base 304 k Transaction Summary ==================================================================================================== Install 1 Package Total download size: 304 k Installed size: 917 k Downloading packages: warning: /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 Public key for net-tools-2.0-0.17.20131004git.el7.x86_64.rpm is not installed net-tools-2.0-0.17.20131004git.el7.x86_64.rpm | 304 kB 00:00:10 Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 Importing GPG key 0xF4A80EB5: Userid : "CentOS-7 Key (CentOS 7 Official Signing Key)" Fingerprint: 6341 ab27 53d7 8a78 a7c2 7bb1 24c6 a8a7 f4a8 0eb5 Package : centos-release-7-0.1406.el7.centos.2.3.x86_64 (@anaconda) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : net-tools-2.0-0.17.20131004git.el7.x86_64 1/1 Verifying : net-tools-2.0-0.17.20131004git.el7.x86_64 1/1 Installed: net-tools.x86_64 0:2.0-0.17.20131004git.el7 Complete!
2. Try ifconfig command :
# ifconfig ens160: flags=4163mtu 1500 inet 192.168.0.18 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 fe80::20c:29ff:feba:3efe prefixlen 64 scopeid 0x20 ether 00:0c:29:ba:3e:fe txqueuelen 1000 (Ethernet) RX packets 10357 bytes 9459534 (9.0 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 8239 bytes 2341646 (2.2 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73 mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10 loop txqueuelen 0 (Local Loopback) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
3. Try netstat command :
# netstat -plunt Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1919/master tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1318/sshd tcp6 0 0 ::1:25 :::* LISTEN 1919/master tcp6 0 0 :::22 :::* LISTEN 1318/sshd udp 0 0 0.0.0.0:47445 0.0.0.0:* 572/avahi-daemon: r udp 0 0 0.0.0.0:5353 0.0.0.0:* 572/avahi-daemon: r
