ho passato 5 ore a debbuggare il problema che si e' presentato ieri,<br>
rendendo anche la mia LAN di casa inutilizzabile...<br>
Finalmente dovrei aver individuato ed isolato il problema.<br>
I pacchetti OLSR che girano ovunque in rete portavano appresso dei<br>
messaggi HNA duplicati con l'originator 172.16.46.1.<br>
Il nodo che origina tale messaggio e' quello di Matteo ad Alberata. Mi<br>
dispiace per Matteo, ma per il momento sono stato costretto ad isolarlo<br>
mettendo un filtro sul traffico UDP con sorgente 172.16.46.1 sul router<br>
"a terra" del Fusolab.<br>
Forse c'e' un metodo per inibire la duplicazione, ma per ora non l'ho<br>
trovato.<br>
Sembra che ci fosse tanto tempo fa un bug di OLSR che produceva un<br>
problema affine:<br>

Matteo aggiorna il tuo OLSR e cerca di capire perche' invii in rete<br>
messaggi duplicati...<br>
Ciao<br>
Nino<br>

Riporto un dump un dump di parte del pacchetto OLSR incriminato....<br>
