cudan protok na sbb-u
Od pre nekoliko dana imam konstantan protok od jedno 2KB/s preko kablovskog modema. Skinuo sam neki packet sniffer i on kaže sledeće:
Packet #4851, Direction: Pass-through, Time:21:27:59.466, Size: 60

Svi su paketi uglavnom takvi, mada se target adrese razlikuju. Sve su oblika 10.1.x.x, što će reći iz onog opsega koji se ne vidi spolja.
Ima i par ovakvih:

U principu sve ovo mi ne smeta jer transfer ide normalno, samo je ukupan transfer rate sada veći nego što je bio, oko 9 KB/s prema DU Monitor. Ipak, ne dopada mi se što se nešto promenilo tako odjednom. Plus što mi poremećuje statistiku. :)
Ako neko ima objašnjenje, bio bih mu zahvalan.
