Hi ck,

I'm getting a strange json error in my logs.

Looks like connector.c is not stripping HTTP from the json before it submits to json_load

Code:

Connector created new client instance
[2018-07-11 14:59:53.478] Connected new client 0 on socket 12 to 0 active clients from 192.168.x.x:59482

Hmm, nope, it looks like your client is sending a http encapsulated request for getblocktemplate instead of a json message and ckpool is simply dumping the entire message as is, rightly saying it's not valid json. Looks like the client is trying to mine with the defunct getblocktemplate mining protocol instead of stratum. It's also a shitcoin miner based on the mining software id it's giving you.

Hello,

on some VPSes I cna't change this value. is there way so that the passthrough would be working?
so it show only notice, that those values needs to changed (or recommended) ?

I also don't quite understand, user and password. can we skip it in the passthough mode?
Since I want my rigs to set the username/password themseved?

(btw it should work on algos, for example x17, lyra2z etc?)
thank you

Username and password is ignored in passthrough mode. The segfault is actually a recent bug and nothing to do with those privileges. I haven't had time to go and fix it so you could check out an earlier commit and use that for passthrough instead. A known good commit was 64961e4091b053935e57eabe346f59964c1bbb70

Probably. The passthrough has received virtually no attention since I abandoned helping Kano's pool so it's in a sorry state I'm afraid to say since I've had no use or need for it, and no one has funded work on it.

seems that ckpool binary tries to athorize rigth away, but it should probably do it on first user connect?
I try to configure some shitcoin algo maybe it's not suitable for this?

btw, can't simple proxy written it work? I mean if I only need to 'bridge' traffic?

You're on your own now.

Well you have succeeded in breaking it with 100% guaranteed failures ... and your competition was affected in each case.

3 times I can remember I've had to fix:
1) there's a deadlock that occurs 100% of the time for a 'real' pool, in the stratifier that I reported to Lightsword
2) the passthrough crashes 100% of the time on startup
3) the passthrough fails to submit ALL blocks that have an asicboost version mask

Though I'm not sure why you think that someone will pay you to fix the breakages you added ...

Please remove it - since you make claims about how good it is in all material describing your minor subset of the ckpool code ... yet never bothered to point out how dangerous it is for anyone to use due to your regular breakage of it.

Hey -ck

im trying to add a dragon t1 to my ckproxy

what do i need to put on the url line for it to connect?
i put
stratum+tcp://192.168.0.12:3334
didnt like it
i put
192.168.0.12:3334
didnt like it

im using this (192.168.0.12:3334) on my s9's
and they connect fine

Do you have the latest ckproxy from git to ensure you have working support for asicboost and are connecting to a pool upstream that has asicboost?

I was testing the latest code in proxy mode which starts up fine and works with my antminers no problem.

However, I get the following when a Halong T1 tries to connect to the proxy:

The T1 will connect directly to slush pool without a problem.

I want to set up an isolated lab where I read the software sources, execute for a bit, and see what happens.

In my particular scenario I will use an earlier version of the reference bitcoin client and download about 10,000 blocks.  The difficulty will be 1 at this point.

I will use cgminer and ckpool as well, to develop what skill I can at understanding stratum and how to configure the servers and what they do.

Toward that end I have made the most recent version of ckpool, and started it with
  ckpool -l 7 -A -H

and ckpool.conf points only to my local setup.

I appear to retreive getblocktemplates, pass info up to cpuminer/minerd, do the magic and send results back to ckpool.  ckpool.log and the consoles for cpuminer and ckpool make sense to me.

I don't grok how to get the new block submitted to my local bitcoind.

For what it's worth, I am looking at line 6225 of stratum.c.  That seems to be one place where I might expect a submitblock to happen, but it does not.

My understanding of "upstream" and whether it is necessary / possible to set up a proxy to make this happen is a bit wobbly.

Oh, and while I am posting, I thought I would mention that I am pretty familiar with GitHub, but not so much with the repository where ck has his source located.  Is there a GitHub bridge (fork) to his efforts, or do I need to figure out the new repository as part of all this effort.

Old versions of the bitcoin daemon do not have the features required for ckpool to work completely, though I don't know how old you're talking about.

There's nothing in line 6225 that has anything to do with submitting a block? test_blocksolve goes to line 5949 which sends it to local_block_submit and in there line 2061 submits it to generator_submitblock and so on.

Bitbucket is the only authentic git repository for my source, so not sure why you need to look elsewhere?

Thanks for your reply.  My current approach with bitcoin is to try to understand virtually every line of code on the version I started with,
then move to the future.  At the moment, I'm marooned pretty far in the past at 0.8.1.  Real Soon Now I will leapfrog forward.

Offhand, do you know the oldest bitcoin version that is supported?

I am looking at the code below, with a small modification that I made.

Code:

if (sdiff >= diff) {
if (new_share(sdata, hash, id)) {
LOGINFO("Accepted client %s share diff %.1f/%.0f/%s: %s",
client->identity, sdiff, diff, wdiffsuffix, hexhash);
result = true; LOGDEBUG("stratifier.c Ln 6223 submitblock <hexstuff>"); // parse_upstream_block(ckp, val);
} else {

Oh, and as for Bitbucket, it's just yet another login / password / interface to deal with.  I'll deal with it.
