Re: [Ninux-Wireless] traffico bloccato da un'antenna dopo eventi strani

2017-02-20 Per discussione Matteo Pedani 
Si mi sembra che il collegamento radio  non funzioni. Magari qualcuno sta
usando lo stesso canale, oppure qualcuno usa le stesse frequenze che usi tu
ma magari neanche tcp-ip  prova a fare air-vgiew con l'antenna

Re: [Ninux-Wireless] traffico bloccato da un'antenna dopo eventi strani

2017-02-20 Per discussione federico la morgia 
Sembra che banalmente 172.31.90.47<http://172.31.90.47/>

ti abbia inviato robaccia tra pacchetti errati e/o troppo corti, vedi cosa 
arrivava da quell'ip ed saprai cosa può essere.

Oggetto: [Ninux-Wireless] traffico bloccato da un'antenna dopo eventi strani

casualmente mi accorgo che da un nodo configurato in modo groundrouter da 
un'antenna il traffico olsr risulta bloccato sia uscita e entrata .

facendo il restart di olsr da entrambi i router non cambiava assolutamente 
niente

ho risolto solo riavviando l'antenna (litebeam M5AC) access point

qualcuno mi sa spiegare il motivo??

ricercando un pò su google sembrerebbe qualcosa tipo: Attacco DDOS o cosa??? ma 
in porte diverse...
