 |
|
On two machines that have been updated regularly and have been working for years, I've suddenly started to get this (below) when the standard netifrc process tries to bring up eth0 using dhcpcd:
| Code: | eth0: soliciting a DHCP lease
eth0: checksum failure from <IP of my dhcp server>
eth0: checksum failure from <IP of my dhcp server>
eth0: probing for an IPv4LL address |
The process continues with IPv4LL address assignment, so I don't have a functional network connection.
Anyone know what might cause this?
Other basic info:
- one of these machines is a basic core2 duo, the other is a xen pv domU on ivybridge hardware
- Both are built to be basic LAMP servers, no X/desktop
- Both are ~amd64 keyworded in make.conf
- both are running profile amd64/17.0/hardened
- The core2 duo is running kernel 5.3.6-gentoo-r1, and the xen vm is running kernel 5.3.4-gentoo

Hi,
What version of dhcpcd do you have ?
Version 8.1.0 is bugged, see 697672

| Thanks, Xavier - that was exactly the problem. I temporarily assigned a static address and then updated to dhcpcd-8.1.1, and it works normally again. |
