[OLSR-users] Re: Problems with 0.4.10 when changing IP address of the main interface

[Andreas Tønnesen]

Ups... there was a problem in the patch I made. I have checked in a fix 
in CVS,
please give it a few hours (for the public servers to update) and 
update, build
and test(src/unix/ifnet.c rev 1.37).
Thanks.

- Andreas
