📝 Original message:I believe the requests Jeff is seeing came from my crawler although anyone
could be running it (https://github.com/ayeowch/bitnodes) since there is no
IP address in the log to confirm the source of the requests.
This is a sample log of an actual request from my crawler at 148.251.238.178
:
*2014-07-30 22:43:54 receive version message: /getaddr.bitnodes.io:0.1/:
version 70001, blocks=313244, us=X.X.X.X:8333, them=0.0.0.0:0
<http://0.0.0.0:0>;, peer=148.251.238.178:47635*
Currently, the crawler takes a full snapshot of the network of reachable
nodes as soon as it is done with previous snapshot. I want to be able to
diff between the snapshots to get the join and leave nodes periodically.
Each full snapshot is taken on average between 3 to 4 minutes hence the
requests that you see from the crawler every 3 to 4 minutes.
I have a task in my schedule (
https://github.com/ayeowch/bitnodes/wiki/Schedule#crawlpypingpy) to improve
upon this method by skipping a new connection with currently reachable
nodes while still being able to perform the diff.
