What is the equivalent terminal command to ipconfig /all?

Question

In windows I can use ipconfig /all and this displays all the info about my connection.

In terminal using ifconfig does not and only supplies limited info. I can use network manager, but it would be useful to know the command line alternative.

So my question is: what is the command line to supply ip address, gateway, subnet mask, DNS the same way ipconfig /all supplies in Windows.

Thanks all

The only thing missing from ifconfig are the gateway and DNS servers.

15.04 and newer

To get the DNS and Gateway info just type:

nmcli dev show eth0

The output lists some device parameters including some IP4.DNS[x] entries, which show the DNS servers and a IP4.ADDRESS[1] line which lists the IP and Gateway used (look for the gw = ???.???.???.??? part at the end of the line up to 15.10). On 16.04 and newer versions there is a IP4.GATEWAY line which is pretty self explanatory.

Replace eth0 with the actual device name you're using, which may not be the same. To get a list of devices and their status type:

nmcli dev status

Up to and including 14.10

You can get these with nm-tool (in Ubuntu versions prior to 15.04) which BTW is the command line version of network manager.

To run it just type in a terminal:

nm-tool

If you're using Ubuntu 15.04 or newer the nm-tool has been replaced by the nmcli command which is different. Check the section called "15.04 and newer" above this one in this case.

Using `nmcli dev show eth0` results in this: Error: 'dev' command 'show' is not valid. – Enkouyami Jul 27 '15 at 15:42

@Enkouyami What Ubuntu and nmcli versions are you using? – devius Jul 27 '15 at 17:51

@devius nmcli v0.9.8.8 on Ubuntu 15.04. – Enkouyami Jul 28 '15 at 09:33

@Enkouyami I'm using 0.9.10 and it works just fine. Not sure if this particular command is a new addition or not, but you can try to get help by using `nmcli dev help` to see which commands are available. – devius Jul 28 '15 at 10:39
This does not work on Linux Mint 17 based on Ubuntu 14.04. The command to use is `nmcli d list` which shows info for all connections, connected or not. – CoderGuy123 Jul 28 '16 at 13:23
just do **nmcli device show**, from there you can get the device name – userDepth Jul 21 '17 at 17:56

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 and servers.

cat /var/lib/dhcp/dhclient.leases

Was looking at few links and finally found the below working:

nmcli dev list | grep IP4

The output is:

IP4.ADDRESS[1]:                         ip = 195.168.0.107/24, gw = 192.168.0.1
IP4.DNS[1]:                             192.168.0.1
IP4.DOMAIN[1]:                          local

Also all the network related details can be found using putting simply:

nmcli dev list eth0

ubuntu chromium

`nmcli dev list | grep IP4` means take the output of `nmcli dev list` and then feed it (using the pipe `|`) into `grep` and keep lines that contain regex pattern `IP4`. – CoderGuy123 Jul 28 '16 at 13:25
`nmcli dev list | grep IP4` doesn't work on Ubuntu 16.04 – Danibix Jan 18 '18 at 10:48

Here's the simplest equivalent i could find for ubuntu 17.04

nmcli device show

Sample output (ip4 stuff only):

nmcli device show | grep IP4
IP4.ADDRESS[1]:                         172.27.35.55/24
IP4.GATEWAY:                            172.27.35.1
IP4.ROUTE[1]:                           dst = 169.254.0.0/16, nh = 0.0.0.0, mt = 1000
IP4.DNS[1]:                             172.27.35.1
IP4.ADDRESS[1]:                         127.0.0.1/8
IP4.GATEWAY:

Finally! This worked on Ubuntu 21! – Joe Oct 11 '21 at 01:42 — Joe, Oct 11 '21 at 01:42

I needed to work out what DHCP server I was connected to via Ubuntu 14.04 so I used this command:

nmcli dev list|grep DHCP4

as this is what I wanted only from the original command "nmcli dev list"

DHCP4.OPTION[1]: expiry = 1464073312

DHCP4.OPTION[2]:  domain_name = [omitted_proper_details]

DHCP4.OPTION[3]:  broadcast_address = 10.1.45.255

DHCP4.OPTION[4]:  dhcp_message_type = 5

DHCP4.OPTION[5]:  dhcp_lease_time = 432000

DHCP4.OPTION[6]:  ip_address = 10.1.45.132

DHCP4.OPTION[7]:  subnet_mask = 255.255.255.0

DHCP4.OPTION[8]:  dhcp_renewal_time = 216000

DHCP4.OPTION[9]:  routers = 10.1.45.1

DHCP4.OPTION[10]: domain_name_servers = 10.1.26.10 10.1.20.10

DHCP4.OPTION[11]: dhcp_rebinding_time = 378000

DHCP4.OPTION[12]: network_number = 10.1.45.0

DHCP4.OPTION[13]: dhcp_server_identifier = 10.1.20.10

Gives me all the DCHP/DNS details I need, just like ipconfig /all

What is the equivalent terminal command to ipconfig /all?
