Hello,

Just recently my dhcpcd 6.11.5 started logging lots of messages like this:

eno1: truncated packet (0) from 101.249.179.246
eno1: truncated packet (0) from 180.95.225.130
eno1: truncated packet (0) from 219.142.242.201
eno1: truncated packet (0) from 171.12.10.197

I don't really understand why this is happening. Is the daemon trying to reach
those external IPs? Or are these incoming connections from outside that are
not properly filtered by the ISP?

It means you received a BOOTP packet from these machines which is invalid - basically it's too short to be a proper BOOTP message. I would guess someone is trying to hack your DHCP client and dhcpcd is being noisy about it.
