Slow connection

eexxil · 8 March 2023 13:39

I had some issue with my VPN, it was not giving me the results I expected, so the VPN support had me do this:

"sudo rm -r /etc/resolv.conf
sudo nano /etc/resolv.conf

You will be asked for your root password after each command line, so just type it in and press enter. When the text editor opens, you will have to type in these lines:

nameserver 162.252.172.57
nameserver 149.154.159.92

Now you have to close and save the file, you can do that by clicking Ctrl + X and pressing Y.

After that, please type in the last command in the terminal:
chattr +i /etc/resolv.conf

Once you are finished, just reboot your device to successfully apply these changes!

I would like to note that if chattr +i does not work, try using the following command instead:
sudo chattr -f +i /etc/resolv.conf "

After this every time I open a new internet page it takes for ever to load.
I tried to run this again sudo rm -r /etc/resolv.conf to remove the changes and hopefully have the system recreate the file, but I got a permission denied.

Do are you connected with the VPN? You’re routing all your traffic through their infrastructure which might be slow.

eexxil · 8 March 2023 13:53

No, sorry. I should have been clearer.
I use VPN for certain tasks, but mostly I am working off VPN.

TriMoon · 8 March 2023 14:09

These lines when put in /etc/resolv.conf forces to you your VPN’s DNS for all connections…

These commands prevent any modifications of that file.

The permission error is cause due to the above command.
The file will not be recreated, but the default for it is to be a symbolic link to /run/systemd/resolve/stub-resolv.conf

Then you should not make the above changes, but instead create separate connection profiles for the different needs…

VPN connection with it’s routing to your VPN and DNS settings.
Non-VPN connection with your normal routing to your ISP-modem and DNS settings.

If (1) doesn’t seem to work you need to check your VPN settings but at same time allow the traffic to use your ISP-Modem as the gateway, because all traffic needs to pass your modem to be able to go out.

eexxil · 8 March 2023 14:26

Sorry for being a bit thick.
What you say is that I cannot undo the changes because of the chattr command.
But by running this command:
/run/systemd/resolve/stub-resolv.conf

I can bypass the resolv.conf file?

If that is so, should I put something in the stub-resolv.conf?

mithrial · 8 March 2023 14:59

No.

You put a write-protected setting on the file /etc/resolv.conf, so it can’t be changed by anyone.
First, you have to undo that:

sudo chattr -i /etc/resolv.conf

Then, you remove this file:

sudo rm /etc/resolv.conf

And reset it to the default value:

sudo ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

Then, enable and activate this DNS resolver:

sudo systemctl enable --now systemd-resolved.service
sudo systemctl restart systemd-resolved.service

At least, then your “normal” internet should work and it will use the DNS servers from your router or ISP.

If you have this running, we could look into either the VPN issue or the slow connection. I’m not sure if it’s a combination of both or separate issues.

Without hardware information, we can only guess.

Thank you!
My internet is back to normal.
