@Tealk
Thanks for your report.

Hmm, here it works:

Also your error massage indicates, that your name resolver/DNS entry seems to not work, thus you should be not able to connect to any web resource, besides entering the plain IP.
To verify, wget --spider http://google.com should throw the same error message to terminal.

How did you configure your network connection? Did you adjust something inside dietpi.txt?
If not, then DHCP via Ethernet is default and the DHCP server should as well serve a DNS server.
Check: cat /etc/resolv.conf

If there is no (valid) entry, then try to set a static IP with dietpi-config > Network Options / Adapters and set e.g. google DNS server as static DNS entry: 8.8.8.8 8.8.4.4

@MichaIng
Thank you for the answer.

I have configure nothing, only install the image and connect the raspberrypi connected to power and internet

Here the wget test:

I use DHCP my dns server i have set up in the fritzbox 213.73.91.35 and 89.233.43.71
My tower can resolve http://raspbian.raspberrypi.org/raspbian

Sorry atm i have no card reader here, so i cant check the files, or is it possible to enable sftp?

[Tealk]

i have now set up the dns server static on google and now it run fine :/

[MichaIng]

@Tealk
Hmm, so google.com resolved, before you applied static IP+DNS? Strange. The DNS servers inside fritzbox look fine and it should automatically apply them correctly to DHCP clients.

But if it works now with static IP, okay. It anyway makes sense, if you can control the DHCP server. Be sure that you assign always the same IP to the RPi within fritzbox settings.

You don't need indirect file access via sftp or something like that to check file content. Just use the command cat /etc/resolv.conf (post content within terminal) or nano /etc/resolv.conf (cmd file editor), or did I misunderstand?
But just for completeness: You can enable sftp e.g. by choosing OpenSSH within dietpi-software as SSH server and enable its internal SFTP module: https://goneuland.de/wordpress/debian-8-jessie-sftp-server-einrichten/

• Guide is in German language, but according to the DNS servers, this should be fine 😉?

[Tealk]

i don't understand why the pc could resolve the domain but RPi just couldn't

Could be any of the following:

• http://raspbian.raspberrypi.org/raspbian temporarily offline (common)
• Configuration issue on the router
• incompatibility with RPi
• bug with router (check firmware updates)

i have now set up the dns server static on google and now it run fine :/

As this issue is now resolved, and, we are unable to replicate it our end, i'll mark it as closed. However, please free to continue discussion as needed.
