1 2017-10-19 16:11:54 <Sentineo> does not seem like lucky, all my outgoing connections are ipv6 on my node. Is this intended? Not the first time I see this behavior ...
 2 2017-10-19 16:15:05 <wumpus> that's interesisting, I see mostly the opposite behavior, outgoing connections are seldom ipv6. Somehow your node knows mostly ipv6 peers? Is your ipv4 working or somehow firewalled?
 3 2017-10-19 17:29:05 <Sentineo> wumpus: I have a public ipv4, the ipv6 is a 6to4 tied to my ipv4. I see a lot of ipv6 connection errors on my anither node that is not reachable from outside.
 4 2017-10-19 17:32:29 <Sentineo> wumpus: the ipv4 is firewalled on my side, the isp has no firewall rules on it.
 5 2017-10-19 17:34:51 <wumpus> so I expect it's unable to make ipv4 connections to many nodes for some reason, and ipv6 connections succeed
 6 2017-10-19 17:36:21 <wumpus> a way to force it to make ipv4 connections would be with addnode w/ known nodes
 7 2017-10-19 17:53:44 <Sentineo> ok, I have shut down my uto4 iface, lets see if I loose all connections outside

 9 2017-10-19 18:36:39 <sepisoad> hi, i want to develop a web service which offers some bitcoin functionalit, like creating a wallet, sending/receiving coins or getting balance
10 2017-10-19 18:37:32 <sepisoad> now, my question is that can i use a light version of bitcoin client and use bitcoin RPC json api, I do not want to download the whole bitcoin blockchain
11 2017-10-19 18:38:23 <sepisoad> if my question is opaque please let me know so that I try to explain it another way (sorry for my poor english)
12 2017-10-19 18:41:34 <wumpus> if you run a online bitcoin wallet service, and hold money for others, you should definitely run your own node, and not take the risk of running a light client
13 2017-10-19 18:43:35 <wumpus> and if you use e.g. electrum would suggest you run the server(s) yourself
14 2017-10-19 18:43:46 <wumpus> to not be dependent on a third party
15 2017-10-19 18:53:33 <Sentineo> yeah so if you do that you might as well run bitcoin-core ... cause you need core for electrum server :)
16 2017-10-19 18:53:59 <wumpus> yes
17 2017-10-19 18:54:01 <Sentineo> ah he is not here anymore
18 2017-10-19 18:57:05 <wumpus> I think it's quite sad, people wanting to create services with so much at stake, but too cheap to run even their own node. I don't want to think of the other security compromises they make.
19 2017-10-19 19:06:25 <Sentineo> yeah
20 2017-10-19 19:06:56 <Sentineo> wumpus: btw yes there is something filtering my ipv4 that goes out so it seems, after turning off the 6to4 tunnel only incoming connections remained on the node
21 2017-10-19 19:07:14 <Sentineo> will have to hunt down the rule that does it
22 2017-10-19 19:08:08 <wumpus> you can make outgoing connections on port 8333 can you try with e.g. telnet or nc?
23 2017-10-19 19:09:00 <wumpus> 163.172.61.48 8333 should be open
24 2017-10-19 19:37:37 <Sentineo> yeah I could make it there
25 2017-10-19 19:38:56 <Sentineo> I have no response, but the tcp socket is up
26 2017-10-19 19:39:12 <Sentineo> I mean sending some ascii on 8333 will not make the other side reply me ;)
27 2017-10-19 20:00:00 <wumpus> right, typing anything won't get anything back
28 2017-10-19 20:00:04 <wumpus> you could try to addnode it
29 2017-10-19 20:00:44 <wumpus> another thing you can try is shutdown your node, rename peers.dat to something else, then restart it
30 2017-10-19 20:00:53 <wumpus> it might be that, somehow, it only knows about ipv6 nodes
31 2017-10-19 20:02:26 <Sentineo> yeah, will try. waiting for the node to shutdown
32 2017-10-19 20:02:42 <Sentineo> I naivly thiught at first that address families do not mix
33 2017-10-19 20:03:17 <Sentineo> so an ipv4 only node should not know about ipvu peers
