The dhcp server is systemd-networkd, and the dhcp plugin can request an ip but can not renew it. The systemd-networkd just ignore the renew request. ``` 2024/09/14 21:46:00 no DHCP packet received within 10s 2024/09/14 21:46:00 retrying in 31.529038 seconds 2024/09/14 21:46:42 no DHCP packet received within 10s 2024/09/14 21:46:42 retrying in 63.150490 seconds 2024/09/14 21:47:45 98184616c91f15419f5cacd012697f85afaa2daeb5d3233e28b0ec21589fb45a/iot/eth1: no more tries 2024/09/14 21:47:45 98184616c91f15419f5cacd012697f85afaa2daeb5d3233e28b0ec21589fb45a/iot/eth1: renewal time expired, rebinding 2024/09/14 21:47:45 Link "eth1" down.

|
|
|
|
Package `socket` provides a low-level network connection type which integrates
|
|
with Go's runtime network poller to provide asynchronous I/O and deadline
|
|
support. MIT Licensed.
|
|
|
|
This package focuses on UNIX-like operating systems which make use of BSD
|
|
sockets system call APIs. It is meant to be used as a foundation for the
|
|
creation of operating system-specific socket packages, for socket families such
|
|
as Linux's `AF_NETLINK`, `AF_PACKET`, or `AF_VSOCK`. This package should not be
|
|
used directly in end user applications.
|
|
|
|
Any use of package socket should be guarded by build tags, as one would also
|
|
use when importing the `syscall` or `golang.org/x/sys` packages.
|

|
## Stability
|
|
|
|
See the [CHANGELOG](./CHANGELOG.md) file for a description of changes between
|
|
releases.
|
|
|
|
This package only supports the two most recent major versions of Go, mirroring
|
|
Go's own release policy. Older versions of Go may lack critical features and bug
|
|
fixes which are necessary for this package to function correctly.
