Split: Network Manager broken

[Member metalinchains]

Hi!
I made a mistake with the network-manager and now i’m unable to use internet. Both interfaces are up and pinging
8.8.8.8 without problem but i cannot surf the net or install packages(it say that i don’t have network connectivity). Its possible to restore
the installed system to its defaults with the live environment? Cos i blew up connman and the network-manager. I only need to restore the network-manager part but i cant reinstall them without internet. I don’t have a snapshot.
Thanks!

You may want to reinstall the software rather than attempt to somehow fix this.
Does your live environment work? Or another question is, do you have a working, usable USB available?
IF yes to either of these, reinstall.
If not, then find a way to get another installable live USB and start over. Don’t change the network manager, use Connman; if it doesn’t work, send us the output of an inxi -Fxz listing from live media and as many details about the things you have done, and what has been attempted to fix it.
Whatever you did the last time, don’t try to repeat it, try to reinstall from fresh media. If that works, the problem can be solved without going through steps that clearly lead to your previous issues. I hope this is helpful.

You could boot from antiX Live USB stick (or DVD), then use apt in a console window (e.g. ROXterm from menu) to download the package(s) you want to reinstall on your system (along with all their dependencies, which should be downloaded automatically this way), store these on hard drive and install from these files after you have rebooted to your default installation again.

Commands needed:

sudo apt-get update
sudo apt-get install --download-only <package>

you’ll find the package files in
/var/cache/apt/archives

Copy them to the respective place on your hard drive so you can use them on your damaged system for reinstall without having to download from within it.

Btw, obviously you can ping the outside network, this means your network is fine. There is probably a problem either with your name resolution or with the setting of your default gateway the programs use. You might check first whether you can ping from console still when using the URL instead of the IP (e.g. ping <whateverdomain>.com instead of ping 1.1.1.1). If this fails there is a problem in name resolution (dns) only.

Windows is like a submarine. Open a window and serious problems will start.

I’m from from a networking expert, so if I make an error in the following, I hope that more knowledgeable people will correct me.

Since you seem to be not achieving DNS resolution, you might check the contents of /etc/resolv.conf.

cat /etc/resolv.conf

It should contain the IP address of your DNS, usually your router. It should be something like

nameserver 192.168.1.1

It might have a different IP address.

If not, open a terminal window, and type the following commands (enter key after each) :

sudo cp /etc/resolv.conf /tmp
sudo geany /etc/resolv.conf

In Geany, enter the line

nameserver 8.8.8.8

at the bottom of the file, and save the file.

Then in your terminal window, type

ping google.com

and hit enter. You should get a series of lines that say something similar to (the important part is the “64 bytes”) :

64 bytes from 142.250.190.142: seq=0 ttl=63 time=44.673 ms

If not, sorry, that didn’t help.

Thanks you all people! I solved the issue reinstalling. Despite the issue being solved i will take notes for the future.

Very strange.. i reinstalled the network manager on top of the one that comes with the installation. That screwed the DNS resolution apparently cos i was able to ping from the console only using ip but not to a domain name. The browser was unable to navigate. Apt was unable to download anything at all… that moment i knew i was in trouble. I reinstalled and now is working.

Congratulations on your success!

Glad it now works.

Its some kind of magic involved in the making of Antix? Its supper efficient. I stress test an atom netbook. The system always flows smoothtly. The installed OS is always loaded into ram?
I never achieved this level of efficiency before.

The “trick” is to select as many “efficient” applications as possible.

Also someone recently did an analytical comparison between antiX and MX Linux, because we “share” some of our developers and tools for certain things.
The antiX kernel is definitely “tuned” differently, and more specifically for older systems, and with respect to systems that have limited resources.

It *may* be possible to find a small number of distributions that consume fewer resources than antiX, but 1) There are not very many of them, and 2) Those that are even leaner definitely have fewer features and more limited capabilities.

I’ve been personally using this distribution since I first saw a post many years ago in the old MEPIS Lovers Forum, describing a new, lighter system that would run in RAM after booting directly from CD. That distribution was antiX – more than fifteen years ago! While the size and scope of the distribution has grown a little bit over the years, it’s always remained as lean and efficient as possible, attempting to strike a balance so that it will work with systems that are “relatively new”, but definitely aimed squarely at systems that are 5-10 years old, sometimes older than that!

Many of our users can speak volumes about how they run with older systems. Until 2018 I had two computers dating back to the 2007-2008 time period, and antiX was one of only 3-4 distributions I could still run on their 32-bit processors. Prior to 2009 I had a 2000-ish vintage Dell Dimension 4100 desktop and I had my own customized version of antiX Core that I ran on it. So there is a LOT you can accomplish with antiX!

I hope you enjoy it as much as I do.
