Moved to a Friend's and Ethernet Will Not Get IPV4

Hey guys,

I just moved and am trying to connect my laptop via Ethernet and am having no luck. I was hoping someone might be willing to go through some troubleshooting to see why my Ethernet won't work here. Before I moved, I only used Ethernet and this laptop worked just fine.

I'm willing to shoot any logs that anyone needs. I would send some DHCP logs or something, but it appears to me that things look normal or as per usual. If you think someone could be wrong, let me know what to send. I've gone through Linux systemctl service checks, I restarted my router here as well as the modem, and I have no idea what else to do.

Thanks!

Re: Moved to a Friend's and Ethernet Will Not Get IPV4

First things first:  are you plugged into your friend's router directly, or through an Ethernet switch?  Is your Ethernet device 10/100/1000/2500/10000Mbps?  Can the router/switch support that?  Do you get link lights when you plug it in to the switch/router port?  It's possible the cable has been damaged in transport, try another cable or buy a new one.

I would send some DHCP logs or something, but it appears to me that things look normal or as per usual.

1. what are "dhcp logs"
2. so it's "normal or as per usual" that your ethernet doesn't work?

ip a; ip r
ethtool <device>

And please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

and post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st
