The vast majority of times it has a liveness of 0, i think this host is
one of the ones i copied from http://www.ovmj.org/GNUnet/hosts/

b.t.w. Are the hosts contained in
http://www.ovmj.org/GNUnet/download/hosts.tar.gz still valid for GNUnet
v0.4, or should they only be used with the old version ?

3: 106 - AE470A72DFD9261D87CF9445E9EC590BA12409D5 has credit 0, liveness

I may have something wrong with my setup, im behind a firewall but am
allowing udp trafic in on port 2086. When i do a query "gnunet-search GPL"
i can find data that i have inserted myself, but dont get results from
anywhere else.

This is output when i start searching
WARNING: Not connected to any hosts, can not forward query.

This some other suspect trafic im also suspect about.

verifySKS: host 7C309FD039F498A2216848633EF5018B0371CE65 for sessionkey
exchange not known

closely followed by

SKEY rejected from host 7C309FD039F498A2216848633EF5018B0371CE65 (address 
12.222. 92. 26: 2086): key.len = 38704

Quite a few of these, are they noise packets ?
Received invalid packet (1106 != 20484). Discarded
