Steps to reproduce

Expected behaviour

I'm not sure as this is the first time I try dietpi.

Actual behaviour

in the terminal:
[FAILED] DietPi-Login | Checking network connectivity: ping -c 1 -W 5 1.1.1.1

in the DietPi-Login | Error handler:
Checking network connectivity

• Command: ping -c 1 -W 5 1.1.1.1
• Exit code: 1
• DietPi version: v6.28.0 (MichaIng/master) | HW_MODEL:3 | HW_ARCH:2 | DISTRO:5
• Image creator: DietPi Core Team

• Pre-image: Raspbian Lite

  Log file content:
  PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.

  --- 1.1.1.1 ping statistics ---
  1 packets transmitted, 0 received, 100% packet loss, time 0ms

Extra details

I do not expect a connectivity error as the Internet can be reached (files downloaded), but ping seems to not work from my location.

@seron

many thanks for your report.

Hi, if you are not able to ping 1.1.1.1 you would have local issues as it's part of Cloudflares DNS Server. It is the globally available IP address for Cloudflares 1.1.1.1 DNS resolver:

https://www.dnswatch.info/dns/dnslookup?la=en&host=1.1.1.1&submit=Resolve

Anyway if you like to change this, you can do it as follow.

Do nano /DietPi/dietpi.txt and search for the following 2 lines:

# General connection and DNS testing
# - IP to ping when checking network connectivity. Default: 1.1.1.1 (Cloudflare DNS, should be very fast world-wide)
CONFIG_CHECK_CONNECTION_IP=1.1.1.1
# - Domain to ping when checking DNS resolver. Default: one.one.one.one (Cloudflare DNS domain, see above)
CONFIG_CHECK_DNS_DOMAIN=one.one.one.one

you can change it to 8.8.8.8 and google.com

It's a similar issue like this #3337

Thanks. It worked.

Will changes to /DietPi/dietpi.txt be saved permanently?
