Command to find ipconfig in linux

ipconfig not working

The Ubuntu/Linux equivalent of ipconfig in Windows is ifconfig.

The result will look something like this:

eth0 Link encap:Ethernet HWaddr 00:0c:29:94:37:b6 inet addr:192.168.1.231 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe94:37b6/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:519374 errors:0 dropped:0 overruns:0 frame:0 TX packets:110611 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:332864737 (332.8 MB) TX bytes:11113451 (11.1 MB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:33651 errors:0 dropped:0 overruns:0 frame:0 TX packets:33651 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2951078 (2.9 MB) TX bytes:2951078 (2.9 MB)

This answer was written in 2012, but already back then (and even more now), «ifconfig» was being deprecated. It should be pointed out that the «ip» command will replace it, and the more «modern» way of checking your IP would be ip addr show . More info: serverfault.com/questions/458628/should-i-quit-using-ifconfig

ipconfig is a Windows program — the closest for linux is ifconfig, but contrary to what others (including the accepted «answer») are saying, it is not the same, and does not give the same output at all.

One of the key missing pieces of information in ifconfig is the DNS addresses; they are not there, and there’s not an easy way to find that out. On my system, I have an alias to show some information like that:

nmcli dev list iface eth0 | grep IP4

This will list most of the information I usually want to see. On my system, it shows:

$ nmcli dev list iface eth0 | grep IP4 IP4-SETTINGS.ADDRESS: 192.168.1.110 IP4-SETTINGS.PREFIX: 24 (255.255.255.0) IP4-SETTINGS.GATEWAY: 192.168.1.1 IP4-DNS1.DNS: 8.8.8.8 IP4-DNS2.DNS: 8.8.4.4 

Note that you may need to use a different designation for the network, such as eth1 , eth2 , etc. If you get an error about a device not found, try changing this.

Also note the accepted «answer» is also incorrect in that you do not need to use «sudo» for this command.

If that’s the case, use ifconfig. It’ll give you the same output that ipconfig will on Windows. But ifconfig is now ip a .

and, because the object argument can be abbreviated and command defaults to show, also to

Still, use nmcli as an equivalent command as Marty Fried suggests.

Coming from Windows, when you do ipconfig you probably expect to see a bunch of information such as the network interfaces, ipv4, ipv6 addresses, dns server, default gateways etc. Unfortunately, and as Marty Fried mentions in his answer, ifconfig is hard to extract this information (I’m not even sure it has it at all) so I would say ifconfig and ip addr show are not really equivalent commands to ipconfig because they are missing all this information.

However you can use nmcli :

You can first list all your network interface devices to get the device name:

nmcli dev show | grep DEVICE # output : ' GENERAL.DEVICE: wlp5s0 GENERAL.DEVICE: br-877527cf5a41 GENERAL.DEVICE: docker0 GENERAL.DEVICE: enp3s0 GENERAL.DEVICE: veth9938f55 GENERAL.DEVICE: veth9d03338 GENERAL.DEVICE: lo ' 

or to also see the network device type:

nmcli dev show | grep -E 'DEVICE|TYPE' # output : ' GENERAL.DEVICE: wlp5s0 GENERAL.TYPE: wifi GENERAL.DEVICE: br-877527cf5a41 GENERAL.TYPE: bridge GENERAL.DEVICE: docker0 GENERAL.TYPE: bridge GENERAL.DEVICE: enp3s0 GENERAL.TYPE: ethernet GENERAL.DEVICE: veth9938f55 GENERAL.TYPE: ethernet GENERAL.DEVICE: veth9d03338 GENERAL.TYPE: ethernet GENERAL.DEVICE: lo GENERAL.TYPE: loopback ' 

In my case I’m only interested in my wifi so i’m going to use the GENERAL.DEVICE name of my GENERAL.TYPE: wifi and:

nmcli dev show wlp5s0 # output : ' GENERAL.DEVICE: wlp5s0 GENERAL.TYPE: wifi GENERAL.HWADDR: 34:DE:1A:6D:9B:51 GENERAL.MTU: 1500 GENERAL.STATE: 100 (connected) GENERAL.CONNECTION: room-501 GENERAL.CON-PATH: /org/freedesktop/NetworkManager/ActiveConnection/1 IP4.ADDRESS[1]: 192.168.8.101/24 IP4.GATEWAY: 192.168.8.1 IP4.ROUTE[1]: dst = 0.0.0.0/0, nh = 192.168.8.1, mt = 600 IP4.ROUTE[2]: dst = 169.254.0.0/16, nh = 0.0.0.0, mt = 1000 IP4.ROUTE[3]: dst = 192.168.8.0/24, nh = 0.0.0.0, mt = 600 IP4.DNS[1]: 192.168.8.1 IP4.DOMAIN[1]: lan IP6.ADDRESS[1]: fe80::710e:1bee:cdb4:e281/64 IP6.GATEWAY: -- IP6.ROUTE[1]: dst = ff00::/8, nh = . mt = 256, table=255 IP6.ROUTE[2]: dst = fe80::/64, nh = . mt = 256 IP6.ROUTE[3]: dst = fe80::/64, nh = . mt = 600 ' 

Here’s a function you can add to ~/.bashrc or ~/.bash_aliases :

function ipconfig() < for i in `seq 1 100`; do printf "-"; done; echo ""; nmcli dev show $1 | grep -E 'DEVICE|TYPE|HWADDR|MTU|STATE|CON|ADDRESS|GATEWAY|ROUTE|DNS|DOMAIN|^$' | awk '!NF1'; for i in `seq 1 100`; do printf "-"; done; echo ""; > 

ipconfig # show details of all devices ipconfig eth0 # show only details of eth0

Viewing IP Configuration in Linux Shell: A Guide

The client should simply receive from the server stream whatever it sends. To achieve this, use the solution which displays the interface IP address and broadcast address. As for the server, when you execute a process and read from the input stream, make sure to send the received data to the output stream.

Linux ipconfig command

What is the equivalent terminal command to ipconfig /all?, ipconfig shows things like hostname, DNS servers, those are in a different place than just IP addresses in linux, so you will need a couple of commands. hostname ifconfig -a cat /etc/resolv.conf That shows what I want to see 99% of the time, but ipconfig /all also shows things like DHCP lease times …

Java Executing ipconfig , Client-Server

To avoid making threats, you will have to establish a fresh connection for each request and handle only one connection at a time.

import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.BufferedReader; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.InputStreamReader; import java.net.Socket; import java.util.Scanner; public class ShellClient < public static void main(String[] args) throws IOException < String comando; while (true) < System.out.println("Introduce ipconfig(windows)/ ifconfig(Linux): "); @SuppressWarnings("resource") Scanner keyboard = new Scanner(System.in); comando = keyboard.next(); System.out.println("Conectando. "); // We need a new connection for every request Socket server = new Socket("localhost", 1234); DataOutputStream out = new DataOutputStream(new BufferedOutputStream(server.getOutputStream())); DataInputStream in = new DataInputStream(new BufferedInputStream(server.getInputStream())); out.writeUTF(comando); out.flush(); // We close the output stream so the server knows we have finished the request server.shutdownOutput(); if ("0".equals(comando)) < System.out.println("Finalizado. Gracias!"); System.exit(0); >BufferedReader input = new BufferedReader(new InputStreamReader(server.getInputStream(), "UTF-8")); String line; while ((line = input.readLine()) != null) < System.out.println(line); >// See above - we need a new connection for every request server.close(); > > > 

import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.BufferedReader; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.IOException; import java.io.InputStreamReader; import java.net.ServerSocket; import java.net.Socket; public class ShellServer < public static void main(String[] args) throws IOException < ServerSocket socket = null; Socket client = null; String resultado; String comando; String s = null; socket = new ServerSocket(1234); System.out.println("El servidor sigue funcionando. "); while (true) < client = socket.accept(); System.out.println("El cliente se ha conectado"); DataInputStream in = new DataInputStream(new BufferedInputStream(client.getInputStream())); DataOutputStream out = new DataOutputStream(new BufferedOutputStream(client.getOutputStream())); comando = in.readUTF(); if ("0".equals(comando)) < System.exit(0); >resultado = Shell.CheckCommand(comando); // Ejcutamos el comando Process p = Runtime.getRuntime().exec(comando); BufferedReader stdInput = new BufferedReader(new InputStreamReader( p.getInputStream())); while ((s = stdInput.readLine()) != null) < out.write(s.getBytes("UTF-8")); out.write('\n'); // we want to see each line as fast as we can out.flush(); System.out.println(s); >client.close(); > > > 

To ensure that the Client receives a response, it’s recommended to use BufferedReader (InputStreamReader) to read from the input stream and send the received data to the output stream when invoking a process. Otherwise, the Client won’t receive anything and won’t display any response.

PrintWriter out = new PrintWriter(server.getOutputStream(), true); BufferedReader in = new BufferedReader(new InputStreamReader(server.getInputStream())); out.println(comand); String result; while ((result = in.readLine()) != null )

Receive whatever the server is sending through the stream.

PrintWriter out = new PrintWriter(server.getOutputStream(), true); BufferedReader in = new BufferedReader(new InputStreamReader(server.getInputStream())); out.println(comand); String result; while ((result = in.readLine()) != null )
