[Olsr-dev] [SOLVED] possible bug in IPv6 - txtinfo plugin believes a remote IPv6 is a local IPv6 ?

[ZioPRoTo (Saverio Proto)]

I want to share this experience because really I thought we had a bug in OLSRD.
This was fixed just doing:
echo 0 > /proc/sys/net/ipv6/conf/lo/disable_ipv6

that for some reason was set to 1.

as you can see OLSR had in the links database a lot of strange stuff !!!!
