[OLSR-users] Can't set broadcast address in olsrd.conf - olsrd 0.49

Hi
I am having some problems with a small network of 4 nodes I am setting
up. Each node is running olsr. Specifically, the problem is that the
operation of OLSR seems to be correct but when I send ping packets
between nodes, I am seeing lots of duplicate packets. Before I get
bogged down in alot of detail I just want to check that the olsr
configuration is correct. Perhaps someone can verify that I haven't
made any silly mistakes.
I have included configuration and debug information for one node. I
notice that if I try to set the broadcast address in the configuration
file, I get the error listed below, if it's commented out, I do not get
the error reported.
Thanks
Rae
