===== PeerInfo ===== A simple Python 3 script that parses the output from the getpeerinfo() RPC call. The getpeerinfo() call yields a JSON document that looks like: <file json getpeerinfo.json> [ { "addr" : "200.152.124.103:28333", "services" : "00000001", "lastsend" : 1391707620, "lastrecv" : 1391707647, "bytessent" : 209998, "bytesrecv" : 237591, "conntime" : 1391507320, "version" : 70002, "subver" : "/twisterd:0.9.12/", "inbound" : false, "startingheight" : 22992, "banscore" : 0 }, --- ✂ --- { "addr" : "86.13.244.154:65162", "services" : "00000001", "lastsend" : 1391707647, "lastrecv" : 1391707620, "bytessent" : 78120, "bytesrecv" : 3919, "conntime" : 1391707502, "version" : 70002, "subver" : "/twisterd:0.9.12/", "inbound" : true, "startingheight" : 23302, "banscore" : 0 } ] </file> (some records have obviously been omitted) <file python twc-peerinfo.py> #!/usr/bin/python3.3 # -*- mode: python; coding: utf-8 -*- ############################################################################## # This program is free software; you can redistribute it and/or modify it # # under the terms of the GNU General Public License as published by the Free # # Software Foundation; either version 3 of the License, or (at your option) # # any later version. # # # # This program is distributed in the hope that it will be useful, but with- # # out any warranty; without even the implied warranty of merchantability or # # fitness for a particular purpose.
