Sorry if this has been explained, I tried going through some of the recent pages but all of the idiotic bickering makes it hard to find USEFUL information - but is there something wrong with the stats..? I can't see my miner stats on either wafflepool or Wil's site for the last day or so.

Are you seeing a zero hashrate at wafflepool's page but your miners are still showing hashrate? (Wil's site seems to be down for me right now)
Have you patched to the lastest *gminer to prevent the client.reconnect exploit?
Have you restarted your mining process at all lately?

I've been waiting for the first real DDOS on wafflepool. Congrats, PW, you've now made the big time! Wink

All joking aside, don't sweat it, it'll get worked out and your hard work is greatly appreciated.

@GMC any advise on the R9-280X and HD7950?
where to start with xintensity (my conf posted a few messages back)

Find out how many shaders you have in each card (my 270's have 1280, not sure about the 280 / 7950) and start low with the xintensity (2 or 3) keeping in mind that xintensity is shaders * x. Use the config for both in your cgminer.conf file (IE: "xintensity" : "2,2"). Get cgminer up and running, and then focus on changing the settings for the 280. Keep bumping up the xintensity by 1 until you see a drop-off in your hash rate, go back to the best intensity, then switch to raw intensity.

For my own trial-and-error, I found 3 was the best intensity (1280 * 4 = 3840) then switched to raw intensity and ended up around 4800 (3.75 xintensity).

Remember to set your gpu threads to 2.

Once you've got the 280 running right, then do the same thing for the 7950. I suspect you'll have to start at 1 or 2. I've got no experience with the 7950 so I'm guessing at this point. If you can't use xintensity with the 7950, you can still use intensity, just hit G, then C (change settings) then pick your GPU, then hit I for intensity. Not sure if you can specify both xintensity and intensity in the conf file (it didn't work for me).

Tuning these cards seems to be a combination of blind luck, late nights and the alignment of the stars.

hi all,

total noob here, been mining on wafflepool for the past two weeks, with decent results but have some questions regarding the stalerate, since i am new to this i have not found a guide that explains all the different things in cgminer i.e. thread concurrency and intensity and all that.  I copied my build from a youtube video i am running 6 r9 270x's with a h81btc motherboard etc...  i have been successfully mining for the past two weeks using an intensity level of 20 and a thread concurrency of 24000 this seemed to have worked great for the first week and a half until the stratum change happened, now i have a stalerate of
15m Hashrate   15m Stalerate
2.21 MH/s              2.74%

is this a good number, the stale rate i see jumping all over clear up to 7%

i tried dropping the intensity level down to 17 and my hash rate stayed the same but my "Bitcoins earned (not yet sent): 0.00370838", stopped increasing as fast as it does with the 20.

the last two days i have gone from earning an average of 0.015 to less than 0.010, my most recent payout as you can see is .0079

2014-03-23 16:28:17   0.00797974
2014-03-22 23:08:36   0.01295763
2014-03-21 18:59:12   0.01042906
2014-03-20 18:55:37   0.01317510
2014-03-19 18:28:28   0.01780143


any suggestions would be greatly appreciated


2.21 sounds a bit low; I've got 5 270s (one of which is a 270x) and they run between 2.7 and 3.2 Mhs depending on how generous the hashing gods are feeling.

Definitely switch to Kalroth's cgminer. I did and using xintensity (actually raw intensity) I was able to tune those cards to give me a solid 95 - 110% WUE. A good thread on these cards with xintensity is https://bitcointalk.org/index.php?topic=459419.0

Returning false would make it break, and not read the next line with recv_line(pool), I don't know the code enough to guess if that means it would skip some valid stratum commands.

All in all I like your solution, gotta love opensource software, just because of situations like this.

You're right. In fact, I made it even simpler by just commenting out line 1686

Code:
//pool->stratum_url = pool->sockaddr_url;

This is the line that assigns the new pool url.

Interestingly enough, I don't have a pool 2 defined. I have uswest.poolwaffle.com and useast.poolwaffle.com as the only 2 pools defined (unless the log isn't zero-indexed for the pools - I haven't looked at that part of the code)

If you're using cgminer, start it with 2>cgminer.log to enable logging to a file. I did this and found the following line in the log after two of my rigs were highjacked:

 [2014-03-23 11:34:15] Reconnect requested from pool 2 to 190.97.165.179:3333

If you've compiled your own cgminer source, you can disable the reconnect command. Open util.c and look for this around line 1668:

Code:
static bool parse_reconnect(struct pool *pool, json_t *val)
{
        char *url, *port, address[256];

Right below the opening curly bracket enter:

Code:
static bool parse_reconnect(struct pool *pool, json_t *val)
{
        return false;
        char *url, *port, address[256];

Recompile cgminer and re-run it. It should now ignore any client.reconnect messages from stratum.

Note: I'm still testing this out. This is fly-by-the-seat-of-my-pants work right now, so I'm not sure of the possible implications on how this might affect legit client.reconnect messages, although PW says wafflepool doesn't use this feature.

Oh, thought I'd add one more thing: my rigs run behind a DD-WRT router NAT'd behind a Tomato router, both with very strict policies in place.

This looks more and more like a MITM attack instead of compromised mining software/malware.

cgminer    5820     user   10u  IPv4 3470164      0t0  TCP GPUMiner001:57242->server.live-chat-studio.com:3333 (ESTABLISHED)

 a lie: my other rig that's a clean Ubuntu install was hijacked as well (it was mining DOGE on multipool)


I think a redirection feature must be disabled. Someone is firing redirection packages at will.

I've got a route to 127.0.0.1 in place now for that network now, so if they do hijack my rigs, my hash rate will go to zero, but they'll get no free mining time from me.

Not sure if this is helpful for investigation, but I noticed one of my rigs' hashrate dropped to zero on WP stats, did a lsof -i and got:

cgminer    5820     user   10u  IPv4 3470164      0t0  TCP GPUMiner001:57242->server.live-chat-studio.com:3333 (ESTABLISHED)

(definitely not WP's IP)

Restarted cgminer and went back to:

cgminer     319     user    4u  IPv4 3543219      0t0  TCP GPUMiner001:51742->192.241.211.125:3333 (ESTABLISHED)

This rig is running BAMT / cgminer 3.7.2

I've been working on another rig that's a clean Ubuntu 13 install with cgminer compiled from source, and so far it's not been affected (AFAIK)

Edit: tell a lie: my other rig that's a clean Ubuntu install was hijacked as well (it was mining DOGE on multipool)

New here so hopefully not a silly question but is WU not the most accurate thing to look at to determine your true Hash speed with the pool you are on?

As far as I've been able to determine, Work Utility is the be-all and end-all to how effectively you're mining. It's essentially the end result of everything like rejects, luck in finding blocks, etc. I tune to have the highest possible WU, even over hash rate. From what I've read in cgminer's docs, a WU ratio of around 0.92 (in relation to kh/s) is ideal; I'm not sure if this is still accurate though.

Edit: WU is a stat that is slow to build over time. Not something where you change a parameter, watch it for 30 seconds and change again. It can take hours if not days to give a solid estimate.

Essentially just a load issue.  I was running some profiling today (DB was getting slow), and about 98% of its load was coming from the block lookups (we don't save them separately, so looking them up was digging through the entire shares table), and with people scraping that page, was absolutely raping the db.  Getting rid of it today dropped load from ~4 on the DB to ~0.8 (huge!)

I'd love to add it back, just gotta come up with a nicer way to store it, and move the old stuff into the new system.

Two pages back.

Sounds like a rollup table is your solution, PW, indexed on BTC address.

DogeCoin is about to go to moon and you are mining Litecoin. Why ?

I think Doge is going to be raped and pillaged by the multipools for the next 5 days until 1.6 is released and then it goes back to a normal coin. Doge's price is going to be hammered in the meantime but will probably make a strong recovery over the  next few weeks. Keep in mind, I quite often have no idea what I'm talking about, and this is most likely one of those times.

imo it's not the job of a multipool to keep coins for a longer time than necessary in the hope the price might rise again. it's too risky.

I agree 100%!

It's bad enough around here when payments are delayed a couple of hours, can you imagine the whinging and hollering if the pool lost money because a coin that was being held crashed?

I had totally just woken up when I wrote that.. Oh sheesh I'm a complete idiot for thinking I was the ONLY person using MrWil's website to pull data lol.

Ahhh the human brain was not designed to function without coffee!!! Sad haha sorry

LOL! No worries; I myself typically need a full pot of coffee to be able to tie my shoes, let alone be allowed around sharp objects Cheesy

Eh.. How does that work? My one IP refreshing every couple of minutes enables DDoS protection? Wouldn't miners trip it too everytime they sent/received data, they have to be sending connections far more often than this stats thing?

I'm not sure what PW's back end infrastructure is like but MrWil is aggregating data through PW's web endpoint. If, for example, MrWil's processes are hitting PW's API for 1,000 users, ranging from 1 min to 5 mins each, that's several thousand requests a minute at least to that endpoint. This could definitely look like a DDOS attack to monitoring software.

The mining data is most likely set up a different way. This is an educated guess at best.

Ideally, PW would be setting up rate limiting for the API for general use, and maybe white-listed IP addresses for more intensive services like MrWil's with some kind of rev-share or other agreement in place for the service.

Someone here mentioned it might have something to do with the DDOS protection strengthening we did a few day ago.  I'll contact Wil and see what we can do to make it work.

It makes sense if a single endpoint (or a small number of IPs) coming from MrWil's service is constantly hitting your api URL. I'd imagine that X number of people using it * 1 or 5 min intervals is going to amount to a fair bit of traffic and trigger some kind of anti-DDOS response.
