Script olsrd-neigh.sh lists information about the mesh neighbors. The read_hostnames() procedure therein ignores some IPv6 clients as the input adress is tested against regex [0-9]* .
To include local addresses too, the following diff is sufficient

diff -N olsrd-neigh.sh olsrd-neigh.new
45c45
<                               [0-9]*)
---
>                               [0-9f]*)
