I just experienced this same problem. According to RFC2131, the server is well within its rights to do an ICMP ping to the IP address it's about to offer to the client before offering it and abandon it if it gets a response. So, given this, sending a DHCPDISCOVER message after a valid lease has been obtained can be catastrophic to any established network connections. Sorry for not putting this in the last comment. You can see the DHCP client process failing to send data to the socket by the following messages in the syslog: Nov 8 11:03:49 feather dhcpcd[983]: sendto: Socket operation on non-socket Nov 8 11:03:49 feather dhcpcd[983]: sendto: Socket operation on non-socket Nov 8 11:03:49 feather dhcpcd[983]: dhcpStop: ioctl SIOCSIFADDR: Inappropriate ioctl for device Nov 8 11:03:49 feather dhcpcd[983]: dhcpStop: ioctl SIOCSIFFLAGS: Inappropriate ioctl for device 8.0 has dhclient instead - please give that a try. |
