cannot connect to local network

[mezknight]

I must have messed up the network config in the installation wizard and need help configuring the network parameters.

I know I need to run ifreload -a to update the congifs to live, but as a noob I'm totally lost.

Here are my related files:
cat /etc/hosts

127.0.0.1 localhost. localdomain localhost
192.168.32.50 pue. local pue

# The following lines are desirable for IPu6 capable hosts

cat /etc/network/interfaces

cat /etc/resolv.conf

And here is the ip a and ip r outputs with ping results to 8.8.8.8 as Destination Host Unreachable:

Many thanks for your input.

Your ethernet port enp3s0 seems to have no carrier. Are the link lights on? Did you try a different cable/port/switch?

 

[mezknight]

Thank you for your reply.

I tried enp2s0 ( does this mean I need to physically connect my machine? If yes, does this need to be permanently connected or is this just to get the machine "listed" in the routers DHCP server. ) but it didn't work.


Initially the ethtool enp2s0showed
Speed: Unknown!
Duplex: Unknown! (255)
so I ran ethtool --change enp2s0 speed 100 duplex full autoneg off
according to these two posts : eth0 NO-CARRIER, ifconfig shows no IP address & Network connection not linking permanently

I also ran dhclient enp2s0 : no result

Do you connect Proxmox to a router/switch with a cable?

Obviously, yes, you need to physically connect it. An "enp*" interface is a wired lan, not wifi. The "wlp4s0" interface is your wifi. You might want to reboot too, just to clear out all the stuff you did with ethtool. You almost never need ethtool.

I also ran dhclient enp2s0 : no result

If it isn't connected to anything, yeah, it won't work.

As I said, the wlp4s0 interface is your wifi. But you don't want to use that as your main interface. You really, really don't. For one thing, the tools to configure wifi aren't installed by default. For another it won't work with the vmbr0 bridge and that is how your virtual machines would normally connect to the network. If you really want to use wifi despite it being a terrible idea, see my post here:

Understood, I have connected machine to router via lan.

ping still doesn't work with the following "ip a" output:
Note enp3s0 is no longer "NO CARRIER" (however upon rebooting the machine the status changes for "NO CARRIER" turns on and off, and now without rebooting it switches between appearing and not appearing; I guess I need to try different ports on the machine and router and get a new lan cable.

Any idea why the status of "NO CARRIER" is unstable? Is it safe to assume it's the physical connection problem?

In your file /etc/network/interfaces
change line, it is error configuration
address 192.168.32.50
address 192.168.32.50/24

your router has LAN 192.168.32.1 ?

 

[johnblue]

Line for DNS looks like it has a typo as well .. should it be 192.168.32.1?

 

[mezknight]

Thank you all I am able to have access to web gui after reinstalling with attached physical lan cable.
