| Description |
|
IP address is detection picks up "169.254.x.x" addresses when there are interfaces with actual addresses configured down the list. The detection code incorrectly stops scanning when it encounters a link local address. It should instead of continuing to scan other interfaces for a "better" address.
It's quite normal to assign link local 169.254.x.x addresses to links that do not otherwise have a network address. Our code should skip addresses in this (169.254.0.0 - 169.254.255.255) range and move on to other interfaces. I ran into this on Windows but it probably can happen on any other platforms just as well. Couchbase server ultimately fails to startup with the detected 169.254.x.x address. 1> inet:getifaddrs(). {ok,[{"\\DEVICE\\TCPIP_{F180A16E-C150-4D89-BDC3-56BDD12D0292}", [{flags,[up,broadcast,multicast]}, {addr,{169,254,206,55}}, {netmask,{255,255,255,255}}, {broadaddr,{169,254,206,55}}, {hwaddr,[0,255,144,59,145,135]}]}, {"\\DEVICE\\TCPIP_{5C2FAF9F-3B84-4120-8DDC-0DBC0F8D64D4}", [{flags,[up,running]}, {addr,{192,168,4,208}}, {netmask,{255,255,255,0}}, {hwaddr,[0,19,232,177,113,59]}]}, {"\\DEVICE\\TCPIP_{E29AC6C2-7037-11DE-816D-806E6F6E6963}", [{flags,[up,loopback,running]}, {addr,{0,0,0,0,0,0,0,1}}, {netmask,{65535,65535,65535,65535,65535,65535,65535,65535}}, {addr,{127,0,0,1}}, {netmask,{255,0,0,0}}]}]} 2> addr_util:get_my_address().
