On my X1 carbon, I unplugged the ethernet cable and switched to wireless. I
had a forgotten dhclient running for some time.
ifconfig reports the following:
ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr 54:ee:75:3c:17:cb
priority: 0
media: Ethernet autoselect (none)
status: no carrier
dhclient however spammed me with messages like the following:
Nov 11 13:07:53 carbolite dhclient[24723]: DHCPDISCOVER on em0 - interval 10
Nov 11 13:07:53 carbolite dhclient[24723]: send_packet: No buffer space
available
Nov 11 13:08:03 carbolite dhclient[24723]: DHCPDISCOVER on em0 - interval 1
Nov 11 13:08:03 carbolite dhclient[24723]: send_packet: No buffer space
available
Nov 11 13:08:04 carbolite dhclient[24723]: No acceptable DHCPOFFERS received.
Nov 11 13:08:04 carbolite dhclient[24723]: No working leases in persistent
database - sleeping.
Nov 11 13:13:04 carbolite dhclient[24723]: DHCPDISCOVER on em0 - interval 3
Nov 11 13:13:04 carbolite dhclient[24723]: send_packet: No buffer space
available
Nov 11 13:13:07 carbolite dhclient[24723]: DHCPDISCOVER on em0 - interval 4
My expectation is that dhclient should observe a status of no carrier and
cease attempts to continue blasting packets.
