[SOLVED] Unable To Ping archlinux.org

an4rki_ · 2022-08-24 04:17:27

I am following the installation steps given on the wiki, after I connect to my WiFi using iwctl 'ping google.com' or 'ping youtube.com' works fine. However, I don't get any responses back when I run 'ping archlinux.org' or ping 'gnu.org'
The network interface is up and an ip address has also been assigned to it. Is this a DNS issue? Am I missing any steps here?

Thanks.

To eliminate the possibility of transient network issues, run `ping` on a host it seems to work with (e.g. google.com) and one that looks like failing (e.g. archlinux.org) at the same time. See if they actually both work simultaneously.

If that’s not the case, what is the exact IP address that `ping` tries to use for archlinux.org? 95.217.163.246 or something else?

Can you access archlinux.org and gnu.org in your browser? Can you ping them from another device behind the same NAT?

Yes that's correct archlinux.org is 95.217.163.246 and google.com is 172.217.174.78

Yes I can open them up in the browser from another device, but here's the thing, I do not get responses from gnu.org and archlinux.org when I run ping from this other device as well. ISP issues or something????

ISP issues or something????

95.217.163.246 is in Finland, 209.51.188.116 (gnu.org) in California and "I can open them up in the browser" does not lend itself to the idea that your local dictator wants to ensure that you're thinking correctly.

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f
ip a
ip r
ping -c1 google.com
ping -c1 archlinux.org
ping -c1 2a01:4f9:c010:6b1f::1 (archlinux IPv6)
sudo iptables -nvL
sudo nft list tables

What should I do then? Proceed with the further installation steps?

Ah, you're still installing the system…
As long as you can "curl archlinux.org > /dev/null" it doesn't matter and also the mirrors are gonna be more important.
So yes, see whether you can finish the system installation. We can then try to tracepath archlinux.org and see where that request goes and dies.

Since you however for pretty much sure didn't misconfigure the iso akin to the other device, the ICMP reply seems indeed blocked by the gateway or earlier.
Is there an external firewall? pihole? *Incompetent* local dictator?

Sorry for not mentioning that I was still installing the system. Yes, curl is working just fine. I'll complete the installation first then I'll use tracepath for debugging later.

Thanks.

No, you did imply it in your OP - I was just skipping over the thread

Awebb · 2022-08-24 07:16:06

Since you cannot ping it from another device either, there is nothing wrong with your arch installer and since you can reach the page, I wouldn't worry too much about it from a technical point of view and instead keep a note, in case something comes up later.

You clearly don't live in California.

With all the wildfires I'd not be surprised if some server farms had simply burned down (or alternatively are still just waiting for a solar panel permit), but

Distance California/Finland: 8600km (That's 5344 miles for people who live in California)
The idea was that it's less likely a (common) routing issue to those two rather unrelated locations - except if the OP lives behind a great firewall in a country that's currently dictated by a short-tailed yellow Teddybear.
But then the browser should probably fail as well (though an incompetent short-tailed whatever might actually gray-filter TCP/80 and block pretty much everything else. We'll see)

I'll throw in a bet on an IPv4 / IPv6 issue.
Can you

$ ping -4 archlinux.org
$ ping -6 archlinux.org

?

google.com IPv4 works fine:

curl archlinux.org works fine:
