[SOLVED] odd network behavior

nixIT · 2023-07-15 22:27:50

hello all,

ran into an odd situation today, working with mp3 and copying them to my phone using gmtp.

everything ran smooth then I need to reboot (forgot reason why), and when I logged back into system I didn't have network access.

ip addr showed that my interface was down,

I then performed

sudo netctl restart eth-interface

I saw the lights on the switch come on for a second and then go off. no internet.
I modified eth-interface, changed my static ip to something else and then issued:

sudo netctl restart eth-interface

network came up.
a quick ip addr showed the interface, but now with both IP addresses, the original and the new one I changed it to.

I reboot, and the network doesn't come up, I have to go back into my netctl config file, change my ip address and restart the interface.

the last reboot (prior to the one I noticed today) was yesterday.
system is up to date, with latest updates being yesterday (prior to yesterdays reboot):

updated today:
xfce4-verve-plugin
vulkan-headers

updated yesterday:
signal-desktop
wolfssl
go
calibre

not sure what to look for as I'm not sure what's going on. has anyone seen anything like this?

what info can be helpful to provide?

thanx gang!

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

Other network managing services configuring the NIC, causing collisions. Typical cause.

sudo netctl restart eth-interface

netctl@eth\x2dnetwork.service            | multi-user.target.wants

Those seem different profiles?

Other than that, the only thing I see that could be messing around w/ your network is nordvpn.

After a reboot w/ no internet™ and w/o doing anything to fix that, what are the outputs of

netctl status eth-interface
netctl status eth-network
ip a
ip r
ping -c1 _gateway

thank you @seth, you are da man.

while gathering all the information for you, I noticed there was an error in my /etc/resolvconf.conf file. I was looking into why my nameservers won't revert back when I disconnect from nordvpn, anyway, I fixed that syntax error and now my network is coming back up.

tldr;
it was a S.U.E... Stupid User Error.
