[SOLVED] 5 Seconds Delay (ping, pacman, git clone etc.)

navailable · 2021-12-19 21:14:20

I connect to the internet by running dhclient command on USB archiso image. When I try ping or git clone commands on archiso USB image, it does it instantly without waiting.
You can see on the video:

But after the installation, it always take 5 seconds to do it's thing. Pinging, downloading files or pacman -S something.

I only use networkmanager package and enabled NetworkManager.service to connect internet on my installation. I just want to know what's the reason that takes 5 seconds to do the process.

Here is the video on my installation:

I know it's a weird question but I just want to know why that thing happens. It's also a little bit annoying that delays 5 seconds for whatever the reason.

I'd first suspect DNS issues. Is there a delay if you ping an IP address? Either way, please post the output of the following to list enabled services:

find /etc/systemd/ ! -name *.conf -type f -o -type l

I just tried pinging google by it's IP address (142.250.186.46) and it did that instantly. So now I also suspect that it's a DNS issue. Should I change my DNS server on router?

Here's the output:

You've networkmanager, iwd, dhcpcd and dhclient activated together creating a situation like this:

Pick one, disable the others and see whether that has positive impact.

Oh I was testing them and I already removed them but they appeared as enabled.

So I moved to my old Arch installation backup, here are the all enabled services:

Solved! It was my DNS server that I use on router. Which was Freenom World (80.80.80.80 , 80.80.81.81)

I changed to something else.

Now it works without 5 seconds delay. Thanks for the help!

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Since your router does not seem to cache the configured DNS, you might want to look into a local cache, https://wiki.archlinux.org/title/Domain … NS_servers

I don't know how to mark the topic as "solved" but I found the solution.

[SOLUTION]

* I installed systemd-resolvconf
* I enabled systemd-networkd and also systemd-resolved

Now it works as I wanted by using networkmanager and enabling NetworkManager and systemd-networkd & systemd-resolved

It works and it does not matter which DNS server I'm using. That's great!
