Yeah I see things trying to connect then closing 3 seconds later then connecting again and closing after 8 seconds.... I think this is actual client behavior in some cases however. Occasionally I have seen what looks like a "storm" of connection/disconnections coming from a single IP, but not lately. The most common thing I see connecting every few seconds is the Shoutcast Metadata Puller. Guess I don't want to ban THAT! :-)
I don't know that I could prove it, but I think I see fewer clients connecting/staying connected a short time/ disconnecting / connecting again.... than I used to see with the previous release of DNAS 2.
I also see random sources trying to connect from time to time, and failing password. I assume these ARE some kind of attack.
I have to say that, in general, things seem more stable with this newer release as long as I keep users-per-instance of sc_serv below 300. I mean, the older sc_serv couldn't handle more than 300 either but it also had other things it would sometimes do, like segfault, which this new one just does not do.
Also, the older version used to sometimes cause init to go kinda wacky, burning up CPU cycles. Haven't seen that with this new one. (I have init start my instance of sc_serv, 'cause the old one used to fall over often enough that having it automatically re-start was a good thing. )
