Name Resolution fail

[broetchenrackete36]

For some reason I can't resolve URLs anymore. Pinging an IP address works fine, but pinging an URL doesn't work

root00:51~$ ping google.com
ping: google.com: Temporary failure in name resolution
root00:52~$ ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=112 time=25.6 ms

Not sure when this problem started to appear, it could be after i upgraded from android 11 to 12?

It's also only a problem in arch, works fine in termux itself.

Temporary failure in

Please try ping 1.1.1.1 and share your output? What is the VERSIONID that you are using?

[broetchenrackete36]

pinging 1.1.1.1 works like 8.8.8.8 worked. VERSIONID should be 2.0.1372 (i don't have the setupscript anymore but that's what i found in the setuptermuxarchsysinfo log).

root06:19~$ curl google.com
curl: (6) Could not resolve host: google.com

I don't think it's a problem with ping, curl can't resolve hostnames and yay neither. I managed to install dig and curiously it reaches my DNS Server without problems...

The command ping is working correctly as far as I can see; @broetchenrackete36 a new command is made called pinghelp with the latest commits to help users out with ping; Can you test ping with this command, and share your results from this brand new pinghelp command after refreshing your system with setupTermuxArch re please?

Thank you for providing more information:

curl google.com

Try curl -I google.com please; Also see whether searching check network connection in linux in the Internet helps.

The Termux packages dnsutils, lynx and strace can be helpful in diagnosing network issues. The command telnet can assist as well.
