dhcpd in unknown state

[clarknova]

OPNsense 21.7.4-amd64

The dashboard shows that the DHCP service is not running, but when I click the Start button it still shows stopped and the dhcpd log shows the error "Can't bind to dhcp address: Address already in use".

In the shell I see:

Code Select Expand

rtr01:~ # sockstat -l4|grep 67
dhcpd    dhcpd      27385 24 udp4   *:67                  *:*

Clients are getting dhcp leases, however at least one client is not getting the address that is reserved for it. I don't know if the reservation was possibly created since the service was last started.

Is there a way to force the service to restart in the shell? Any other suggestions short of rebooting OPNsense?

Probably a stale PID file. it has been known to happen and if I recall correctly it was OpenBSD devs who said they don't like PID files because of this but I haven't heard of a better solution. ;)

You can issue this to fix it:

# killall dhcpd
# pluginctl dhcp

That worked. Thanks.
