Ipconfig all в линуксе

What is the equivalent terminal command to ipconfig /all?

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:

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:

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:

If you’re using Ubuntu 15.04 or newer the nm-tool has been replaced by the nmcli command which is different.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.

@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.

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.

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:

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 | 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 .

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

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: 

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

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

Windows ipconfig Equivalent In Linux

Windows operating systems provide the ipconfig command in order to display and manage IP addresses and configuration. Some system administrators and users coming from the Windows operating systems may ask that “What is Windows ipconfig command equivalent in Linux distributions?”. The short answer is ifconfig or ip command which is provided by different Linux distributions like Ubuntu, Debian, Mint, CentOS, RHEL, Fedora, etc. In this tutorial, we will provide how to use the ifconfig and ip commands like Windows counterpart ipconfig command.

List IP and Network Configuration

The most popular usecase for the ipconfig command is listing the IP and network configuration of the current system. ipconfig command will list basic information where ipconfig /all will list more detailed and verbose information.

For Linux distributions ifconfig or ip address command can be used to list detailed IP address and configuration information. Recent Linux distributions do not provides the ifconfig by default but can be installed with the following command for Ubuntu, Debian, Mint and Kali.

$ sudo apt install net-tools

$ ifconfig ens33: flags=4163 mtu 1500 inet 192.168.142.133 netmask 255.255.255.0 broadcast 192.168.142.255 inet6 fe80::281:dc3d:69d1:6cbc prefixlen 64 scopeid 0x20 ether 00:0c:29:e0:58:54 txqueuelen 1000 (Ethernet) RX packets 884353 bytes 1215380632 (1.2 GB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 220346 bytes 16957040 (16.9 MB) 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 1000 (Local Loopback) RX packets 26013 bytes 2566857 (2.5 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 26013 bytes 2566857 (2.5 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 

Also we can use the ip address , ip route commands for specific IP and default gateway information.

$ ip address 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: ens33: mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:0c:29:e0:58:54 brd ff:ff:ff:ff:ff:ff inet 192.168.142.133/24 brd 192.168.142.255 scope global dynamic noprefixroute ens33 valid_lft 1453sec preferred_lft 1453sec inet6 fe80::281:dc3d:69d1:6cbc/64 scope link noprefixroute valid_lft forever preferred_lft forever 

Renew IP Address From DHCP Server

Automatically assigned IP address and configuration can be renewed with the ipconfig /renew command in Windows operating systems. For Linux distributions dhclient command can be used but also the interface named like eth0 should be specified. The interface name can be listed with the ip address command which is explained in previous step.

Flush and Reset DNS Cache

Even Linux systems do not store DNS records in a specific DNS cache some helper services like dnsmasq, pdnsd, nscd and dns-clean can store DNS information. They can be flush or reset like below.

dnsmasq

$ sudo /etc/init.d/dnsmasq restart

pdnsd

nscd

$ sudo /etc/init.d/nscd restart

dns-clean

$ sudo /etc/init.d/dns-clean restart
