Ethernet connection dropping - how to assess?

Hello all,

My ethernet connection drops regularly ( I know it's not the cables as it doesn't on the same machine running Windows 10)

Network is managed by systemd.netword and it drops without any warning nothing from the journal indicates the reasons and reappear after several minutes.

How can I investigate the issue? Is there a tool to monitor the connection?

Thanks,

Re: Ethernet connection dropping - how to assess?

Define 'Drop'.  Does the carrier go away?  Are the link lights on the computer on? how about the router?  Is it possible you still have a link but are losing your IP address?  If you still have an IP address, Is it possible that you can still see machines on your local network?

The router is still working and online - I think I am losing the IP. But the journal doesn't give any indication.

When it drops, post the output of ip addr

Sure about the journal?
Also, ceterum censeo: "systemctl list-unit-files --state=enabled"

Right,

Re: Ethernet connection dropping - how to assess?

ip addr doesn't indicate a connection loss at all - since apparently neither does the journal, what does actually indicate to you that the connection dropped?
Can you still "ping 8.8.8.8" in this situation?

Re: Ethernet connection dropping - how to assess?

No I cannot ping any external or internal IP.

No connection from the browser neither - and as you can see the Journal indicate that the network samba share has lost the connection - cannot access the router through the webpage neither can I ping it.

However, my phone connecting to the wifi is still connected to the outside world?!

Re: Ethernet connection dropping - how to assess?

Ok, things to check:
- raise the systemd-networkd log level, https://unix.stackexchange.com/question … d-networkd
- ditch systemd-networkd and try dhclient or dhcpcd (and just wait whether this still happens)
- your router logs, eg. whether the connection drops correspond w/ lease expirations

Re: Ethernet connection dropping - how to assess?

Thanks,

Will raised the log level to debug, but I am using a fix ip address as opposed to DHCP.  In regards, to the router logs there isn't anything particular showing neither.

Will report once it happens again.

Re: Ethernet connection dropping - how to assess?

There's a hell lot of IPv6 dhcp negotiations, try https://wiki.archlinux.org/index.php/IP … networkd_2

Thank you so much!
