Hallo,

We just changed internet provider (=new router, router ip,..) from the moment we changed I wasn't able to go on my server via the web interface.
If googled it, if tried multiple things like :

- Pinging 8.8.8.8 - got host unreachable
- Pinging other stuff - same output
- Updating host - unable to connect to the websites..

- Changing : /etc/network/interfaces
- Changing : /etc/network/interfaces

Both to what I could find in CMD:
1604334862453.png

- Changing : the ip I used to get in the gui to the ipv4 (it was 192.168.0.232)
- Tried : /etc/init.d/networking restart

etc..

To be fair I don't understand what i'm doing or what I did.. So I think I fucked it up a bit.

My question know can I reset the full network things so the machine can detect the correct things himself? I have never had to change anything on my machine.
I would like it to do it himself the same way he does it in a fresh install.

Thnx,
David

Hi thanks for responding! Beneath you will find both files

/etc/resolv.conf
Code: 
search home
    nameserver 1.1.1.1
    nameserver 8.8.8.8
    nameserver 192.168.1.1
    nameserver 192.168.0.232

/etc/network/interfaces
Code: 
auto lo
iface lo inet loopback

auto eno1 iface eno1 inet manual

auto vmbr0
face vmbr0 inet static
    address 192.168.1.4
    netmask 255.255.255.0
    gateway 192.168.1.1
    bridge_ports eno1
    bridge_stp off
    bridge_fd 0

What I (remember) I did

resolv.conf
  • added the 1.1.1.1
  • think I changed/added both IP's (192.168.1.1 & 192.168.0.232)
192.168.0.232 = the IP I used to go on the interface via webbrowser

network/interfaces
  • added the "auto eno1"
  • think I changed the adress

If you need anything else please let me know!

Thnx
David
