It stated that macchanger was already the newest version, so I typed clear and then ran:. According to your ifconfig -a output, enp58s0f1 is your Ethernet, not eth0. When Ubuntu switched to systemd at Ubuntu Ethernet interfaces start with en so yours is enp58s0f1. Wireless interfaces start with wl.
You might want to do some googling on some basic networking commands and how they work. TLPD has a quick synopsis on some of the most common commands in linux for networking. My arch system is configured to give older interface names, but the newer names automatically configured by ubuntu give newer more complicated, harder to remember, and type information. You can see I have 3 interfaces, lo for loopbacketh0 for ethernetand wlan0 for wireless. If you don't use the correct interface name, then it won't work.
The Ubuntu Server Guide has some detailed information on how to accomplish configuration, bringing the interface down, and back up. Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top.

It stated that macchanger was already the newest version, so I typed clear and then ran: sudo ifconfig eth0 down which is when this error message appeared: eth0 ERROR while getting interface flags: no such device This is a laptop and I am connected via ethernet cable.
How can I resolve this, so that I can run macchanger? So I used ifconfig -a and I'm looking but seeing no mention of eth0 The interfaces that are showing top to bottom are: enp58s0f1 lo tun0 UNSPEC wlp59s0 The only reference to ethernet is the MAC and also txqueuelen Does this help in figuring what I need to do to get this sorted?
Zanna Please edit your question and explain where you see this message, what your hardware is, if this is a wired or wireless connection, what exact command you ran. Run ifconfig -a - is it really named eth0? Rex Nov 17 '17 at Active Oldest Votes. Chai T. Rex Chai T. Rex 4, 1 1 gold badge 20 20 silver badges 42 42 bronze badges. That is so helpful!Imagine you are suppose to reply a very important mail s and you are not able to connect to network… grrrrr….
Have tried lots of thing to solve the issue. I am sure you will get the solution for the same. First, I thought it was an issue with the LAN cable. So tried connecting it another cable. But no use. That was not an issue. The LAN cable was just working fine. Second possible issue, Network Interface Card. That could be a problem as I have ran into similar issue previously and changing the Motherboard have worked.
But unfortunately this time NIC was not the issue. Tried connecting to other LAN ports. No use. Change the hard-drive and connected to the one which has dual boot available. Then thought of booting it from another operating System.
In this case it was WinXP. Booted through it and then tried connecting it to internet. For the first time I was thankful to windows XP. Restarted the system to boot it from ubuntu.
Hmmm, so now the problem was identified. The issue was with the drivers. Connected my hard-drive which has only linux. As it is said everything is a file in linux, one of the file used for networking could be corrupted. Ok, but which file? How do I know that?

Matt said:. October 17, at am. I had this problem with a virtual machine, and changing eth0 to eth1 worked like a charm. Mado Lamotte said:. November 13, at am. November 30, at pm. I run into this issue when I put the HDD with my Debian which is quite similar to Ubuntu into another machine with exactly the same hardware. Googled to this site and the solution worked.

I've also tried another ethernetcard just to make sure it wasn't the card. Didn't work before, after, or when I swapped back again. Any tips? What's about ifconfig -a? Is driver for your network card compiled as kernel module? If it is, check lsmod output for loaded module do it anyway if you don't compile kernel by youself - in distro kernels all drivers are compiled as modules. I have to force eth naming on my system in udev because for some reason because occasionally they are known to switch device names eth0, 1, 2 and such.
I haven't compiled the kernel myself. Can I use hotplug instead? I tried adding allow-hotplug til my interfaces-file, but no change. As eth0 doesn't work the computer has no network access and can not download and install kernel upgrade, or anything else for that matter. Tags eth0 Thread Tools.
It only takes a minute to sign up. I'm new to ubuntu and need to install the ubuntu xenial server After installation I tried to change from dhcp to a static ipv4 address. In my case, my logical network device name is enp3s0. So I replaced the device name from eth0 to enp3s0 and it works. Your network interface is enp0s3.

It only takes a minute to sign up. How can i change that device name back to eth0? Edit: This is not an issue but a new interface naming scheme "Predictable Interface Names", you should adapt and using this instead of try to revert it to the old ones.
I tried all the common answers about adding rules but only this fix worked. I'm running a Raspberry Pi 3 with Ubuntu If you are on Raspbian then it's installed by default. But if you are on Ubuntu, Mint or Mate then you can install it with command below:. This is NOT a "bug" it is a "feature" " consistent network device naming ". I don't see anything consistent about it. To restore previous behaviour add "net. I haven't encountered it specifically with the mac address as part of the name, however what you're experiencing is called consistent network device naming.
This was a change made because it's possible, and maybe even probable on some systems that have multiple network cards that the cards would come up out of order and using the eth0, eth1, etc. Many Linux distributions have moved to some sort of consistent network device naming, typically it will look something like enp0s1identifying the PCI bus and the attachment point to the bus 0 and 1 respectively.
I had the same issue for Ubuntu Server I had the same issue on Raspberry Pi 2 with Ubuntu I found this suggestion here :. It seems to force whatever MAC address is found to eth0. Works on Raspberry Pi and uboot booting systems. I realize that this question is old but I have hit this problem and none of the proposed solutions thus far on this page solved my issue. For me the rules. My solution was to simply write a script that goes in the init. This is important because I have several Raspberry Pi units and they all came down with this same issue.
My issue is compounded because I have a network storage folder that needs to be mounted during the boot process. Because the interface didn't come up, this mount failed and things just went from bad to worse for me.
Here is my solution. I hope this will help anyone else that can't find join using the above answers. I like to use vi. Activate the code so it will execute during the boot process by executing the update-rc. After this, I have not had a single issue and I was able to copy the code to all of my Pi units with the same steady results.

I installed an ran a program to find out details about the network card. Here is that information:. It looks like the network adapters list is empty. I'm still not able to access the internet, even through Windows.
I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine. That's how I'm posting this after all! First of all, your ethernet isn't being managed by Ubuntu. Try ifconfig -a instead of just ifconfigso you can see all your networking devices, managed or not.
If you do see ethX in the ifconfig -a list, the solution should be straightforward, and you seemed to have gotten half of it. However, if you don't even see any ethX interfaces when you do ifconfig -ait's a driver issue Ubuntu isn't even seeing the interface.
An alternative in-linux way to do this is via lspci. I dont see anything in the comments suggesting that you look into udev and its rules which should install eth0. I had a similar problem. By running ifconfig -aI determined that the only network devices on my computer were p4p1 and lo. There was no eth0. The file's contents are now:. The above is what use in Gentoo, I think Ubuntu uses a different mechanism but its worth a shot. Back in Ubuntu 6.
That's a stab in the dark though. You only need to rename the persistent-net. I unplugged the WiFi dongle, and lo and behold I now have wired internet. With the wireless dongle out of course there is now no wlan0. In general if you don't see your network interface, it's either that it has a different name like eth1 instead of eth0 or it doesn't have its driver loaded.

When the dust settled, I typed "modprobe eepro" and naturally got the same error as before. Seems like the card is not being recognized or found. I'm wondering if my other hardware might also not be found. I'd appreciate any help here, obviously without net access I'm stuck with a base install.
Have you loaded the mii module first modprobe or insmod mii? Maybe then you can load eepro The unresolved symbols in your last post have to do with SMP, i. What were the unresolved symbols you encountered in your first post? What kernel are you using? And which modules? Both kernels? If my memory is not totally wrong, the two kernels are slightly different.
The stock pacman-package kernel is SMP, I know. What about the one that boots the install media - maybe marc just copied that kernel for whatever reason. I just vaguely remember similar problems, but I also remember I solved it with setting up properly the kernel and the modules. AFAIK all stock kernels arde smp enabled.
After trying "modprobe eepro", I didn't get the Rsmp error, but still got the other error the "watchdog" error I mentioned previously. Still no progress. I think I'll try loading the "eepro" module. I installed it as a module just in case.
OK, I would not complicate things. It hardly matters that you have SMP in the kernel. Once you have set up your network with a "known" kernel you can move on and compile your own. If the NIC fails then, you most certainly know that something went wrong during compilation. Now, I assume you also rebooted your system? Also, I'm a bit confused about when you are using modules, when you have the driver compiled in and when you are doing a modprobe? That is calling for trouble! You say, you disabled SMP, recompiled everything and installed everything?
Yet you get an unresolved symbol wich has "SMP" in its string? Am I right? The watchdog-messgae has "SMP" at the end.
