Sometimes works fine, sometimes gets in a loop where it keeps creating and destroying utun0:
Thu Oct 29 13:21:08 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:09 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:10 EDT 2015
utun0: flags=8051 mtu 1400
inet --> netmask 0xffffffff
Thu Oct 29 13:21:11 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:12 EDT 2015
utun0: flags=8051 mtu 1400
inet --> netmask 0xffffffff
Thu Oct 29 13:21:13 EDT 2015
ifconfig: interface utun0 does not exist
Thu Oct 29 13:21:14 EDT 2015
ifconfig: interface utun0 does not exist
