Asked: 2024-09-24T16:57:54+05:30 In:

I’m having trouble with network configuration on my Ubuntu system, as the standard ipconfig command isn’t functional. Can anyone explain why this is the case and suggest an alternative method for checking my network settings?

I’ve been diving into network configuration on my Ubuntu system lately, and I’ve hit a bit of a wall. I’m probably missing something pretty basic, but I can’t seem to get the information I need about my network settings using the usual `ipconfig` command. It’s frustrating because I’ve used that command on Windows without issues, and now I feel kind of lost.

I know Ubuntu runs on a different system, but it’s still strange that I can’t just plug in `ipconfig` and get the info I need. Is there a reason why that specific command doesn’t work here? I mean, I’ve done some digging and realized that Linux uses different tools for network management, but I’m not quite sure what the equivalent is.

I did come across a couple of commands, like `ifconfig` and `ip addr`, during my research. But honestly, I’m not clear on how to use them or if they would give me the same kind of output I’m used to from `ipconfig`. Are there specific options I should be using with those commands?

Also, I’ve seen mentions of `nmcli` for managing network settings via the command line, but that just makes my head spin even more. Can anyone break that down for me or suggest the best way to view my current network configurations and settings in a user-friendly way?

It would be super helpful if someone could walk me through it. I’m just a bit overwhelmed right now, and I want to make sure I’m configuring everything correctly. It’s all feeling pretty complicated when it should just be straightforward, you know? Any help or guidance would be awesome! Thanks in advance for any insights!

      Understanding Network Configuration on Ubuntu

      First off, it’s totally normal to feel a bit lost when switching from Windows to Ubuntu—it’s a pretty big change!

      What’s Up with `ipconfig`?

      So, `ipconfig` is a Windows-specific command, which is why it doesn’t work on Ubuntu. Linux has its own set of commands to manage network settings. The good news is that there are some similar commands that can get you the info you need!

      Key Commands to Try

      • ifconfig: This used to be the go-to command for network configuration, although it’s slowly being replaced by newer tools. If you have it installed, just type ifconfig in the terminal, and it should show your current network interfaces and their settings.
      • ip addr: This is a more modern command you can use instead of `ifconfig`. To see your network info, type ip addr. It’ll give you details about your IP address and network interfaces.

      Using the Commands

      No real need for extra options at first. Just running ifconfig or ip addr should be enough to give you a view of your network configuration. Here’s a bit of what you’d expect:

      • ifconfig: Look for inet in the output; that’s your IPv4 address.
      • ip addr: Look for lines starting with inet under each interface to see your IP addresses.

      What about `nmcli`?

      Pretty much a command-line interface for NetworkManager. It can get complicated, but if you want to manage your network settings more directly or if you have multiple connections, it’s worth checking out. You can start by typing nmcli and pressing enter to see a basic overview, or check your active connection with nmcli connection show.

      Conclusion

      You’ve got all these tools at your disposal! It can feel a bit overwhelming, but try running the commands a few times and see what info they give you. It gets easier the more you use them. Don’t hesitate to look up specific commands online; there’s a lot of great community support out there!

      Keep experimenting and you’ll get the hang of it soon!



    2. In Ubuntu and other Linux distributions, the equivalent of the Windows `ipconfig` command is not available because Linux uses a different set of tools for network configuration and management. The command you might have encountered, `ifconfig`, is a traditional utility for displaying or configuring network interfaces. However, it is deprecated in favor of the `ip` command, which provides more features and flexibility. To view your network configuration, you can use the command `ip addr`. This command will give you detailed information about your network interfaces, including their IP addresses and MAC addresses. If you want to see specific information in a more concise way, you can also try `ip a`, which produces a user-friendly output similar to what you are accustomed to with `ipconfig`.

      As for `nmcli`, it is a command-line interface for NetworkManager that allows you to manage network connections and configurations effectively. While it may seem daunting at first, it’s quite powerful for managing and querying your network settings. To view your current network setups with `nmcli`, simply type `nmcli device status` to see connected devices and their statuses, or `nmcli connection show` to see all configured network connections. If you’re looking for something straightforward to dissect your network settings, start with `ip addr` and `nmcli device status`. By familiarizing yourself with these commands, you’ll gain a better understanding of how networking works on Linux and feel more comfortable configuring your system.
