Good stuff. I've been using this build for the past few days, and it's
still working. I tried to trip it up a little bit and it recovered after a
while. So far so good. I'll plan to challenge it more, but first:
A debugging aid that would be helpful for me, which I realized while
staring at all these lines:
{{{
2020/03/23 08:12:40 Traffic Bytes (in|out): 40 | 0 -- (1 OnMessages, 0
Sends)
2020/03/23 08:12:42 Traffic Bytes (in|out): 0 | 575 -- (0 OnMessages, 1
Sends)
}}}
If these log lines could tell me which outgoing connection (aka which
incoming socks connection) these messages were for (even just saying a
SocksId number or something), then when I'm watching to see how it
recovers, it will be easier to tell when snowflake is handling messages
for the *old* connection, vs when it is using the new connection.
I think of this because when I failed my outgoing internet for a while and
then brought it back, and then Tor did the
{{{
Mar 20 09:19:49.331 [notice] Our circuit 3155147085 (id: 27) failed to get
a response from the first hop (0.0.3.0:1). I'm going to try to rotate to a
better connection.
}}}
reaction, I got the impression that a lot of snowflake's alleged sending
and receiving had to do with the old connection for a good while after Tor
had given up on that conn. (I was loading a cnn.com page, and snowflake
sent and received several megabytes and my page still hadn't loaded yet. I
began to question whether the bytes I was getting were even for the page I
was loading.)
It is also definitely possible that I am misunderstanding what's going on,
and the quic messages at that level are e.g. the aggregate for all
currently handled connections. If that's the case maybe I want a breakdown
of how many of them are for which connection.
Thanks!
