can you share your current interface configuration

cat /etc/network/interfaces

mail2rst · June 24, 2024, 1:12pm

my system is directly connected via eithernet wire & no wireless connection

through routher dhcp[ reservation this machine lan ip 10.0.0.10, & router/gateway 10.0.0.1. i am able to ssh via local machines.

Joulinar · June 24, 2024, 1:29pm

interface seems to be set to static but you are running a DHCP client as well.

mail2rst:

Jun 23 10:04:07 XXX.YYY.xyz ifup[11571]: DHCPREQUEST for 10.0.0.10 on eth0 to 255.255.255.255 port 67

Question: should it be static or DHCP??

mail2rst · June 24, 2024, 1:31pm

i want to use static, but system fail each time while i gave the execution command through dietpi-config, network adapter GUI

Joulinar · June 24, 2024, 2:46pm

can you check following

dpkg -l | grep dhcp

I still have some ??? If you switch to STATIC IP, your system is booting still but you are not able to connect? Or is it possible to connect via SSH still?

mail2rst · June 24, 2024, 3:27pm

root@nuc:~# dpkg -l | grep dhcp
ii  isc-dhcp-client               4.4.3-P1-2                     amd64        DHCP client for automatically obtaining an IP address

i am able to ssh the system. but system not switching dhcp to static through dietpi gui & while i gave command process exit with error. locally my system available 10.0.0.10.

Joulinar · June 24, 2024, 3:44pm

that should be fine.

let’s put dietpi-config aside.

/etc/network/interfaces is chowing iface eth0 inet static still? Correct? And on a reboot, you see dhclient request within system log?

mail2rst · June 24, 2024, 3:50pm

this is my file

i am going to reboot system, what thing/command you want to execute after reboot?

Ok, let’s check if there is a conflicting Ethernet configuration file

ls -la /etc/network/interfaces.d/

still strange that an IP address is request via DHCP while the interface has been set to STATIC

mail2rst · June 24, 2024, 4:51pm

Joulinar · June 24, 2024, 5:59pm

Wuppsi did you recall something happening on November 6th 2023?

There a concurrent eth0 configuration has been created. At least our tools are not able to do so

Let’s see what is inside

cat /etc/network/interfaces.d/eth0

mail2rst · June 24, 2024, 6:08pm

root@nuc:~# cat /etc/network/interfaces.d/eth0
auto eth0
iface eth0 inet dhcp
        ethernet-wol g

my system this time doing Wake over lan, i guess these items may be come that time configuring WOL

Joulinar · June 24, 2024, 6:19pm

You would need to remove that file if not needed.

mail2rst · June 24, 2024, 6:25pm

thanks, i remove the file and reboot after that system looks works ok now

Please somebody suggest me eth0 file compatible to dietpi. as this file allow WOL capability to PC.
`

root@nuc:~# cat /etc/network/interfaces.d/eth0
auto eth0
iface eth0 inet dhcp
        ethernet-wol g

`
this time this file make machine WOL compatible but interfere with static/DHCP LAN ip address functionality of dietpi. please suggest the edited version of this file which compatible with dietpi & make PC WOL ready. thanks
