he said he had 0 connections, so it's not even opening any outbound connections. firewall concerns would come after that (unless you're in some environment w/ a firewall that blocks various outgoing connections), if you were able to establish outgoing connections but nothing incoming, then you just check telnet 127.0.0.1 8333 or w/e, see if it's open or not.
but, anyway, try addnode=5.9.24.81 at the bottom of your .conf file
also, ufw is easier to use if you're having issues with iptables

What's so hard about setting up a bitcoin node? Download and run the client with --maxconnections=500 or something..
|
|

If you're on Windows, get Netlimiter. It's awesome for things like that.
i.e. Steam only has the option to limit to 500kb/s or 1MB/s, and it doesn't even do a very good job with it at that.... Since I have 10mbps downstream, both of those options suck. 1MB/s is close to saturating my downstream and 500kb/s uses half... so I set it to 900kbps in Netlimiter and it sticks to exactly that.
alternatively, you could do what I do with my home bitcoin client... just connect to one IP

Use
bitcoin-qt (or bitcoind) --maxconnections=1 --connect=5.9.24.81
until you finish syncing the entire blockchain.
This will help w/ two things, 1) you won't use any upstream (& potentially have downstream limited by saturated upstream) by having or connecting to a client that's also downloading the blockchain, 2) you'll receive blocks as fast as your CPU can process them (I have gigabit connection on 5.9.24.81).

Hey everyone, This topic is geared towards those of us who are mining in our homes, and how to distribute your mining gear within those confines. What I'm really interested in finding out is how people who have multiple TH/s at home are doing it. You so-called garage miners, hobbyists, etc, tell us how you've set things up! Your standard residence has both 15 and 20 amp circuits. Those 20 amp circuits are usually occupied by things like your electric range, washer/dryer, etc. The 15 amp ones manage everything else - outlets, lights, etc. Under continuous load a 15 amp circuit can provide 1440 watts. Since you've got your miners running 24/7, that's what I'd count as continuos load  . We'll use the Antminer S1 as our hardware. It's pretty cheap (about 0.5 BTC) and at normal settings claims 360 watt power usage for 180GH/s, so it's a great candidate for the hobbyist. I read accounts on these boards about folks with 6+ S1s running at their home. At most you're driving 4 of them on a single circuit, which would max out that circuit's capacity for continuous load. So, you'll need to consume about 1.5 circuits for your mining. Do you all just shut those rooms down to anything other than mining? Sorry kids, you can't have separate bedrooms any longer, daddy's gotta mine some BTC! I'll share my setup, which is currently 2 S1s. I have them over clocked and both are driven from a single Corsair HX1050. Together they draw about 800-850 watts. They are in the basement for a few reasons: - It's cooler down there
- Not a lot of power used down there on a regular basis
- No more complaining from the significant other about "those damn mining things"
So, tell us your setups! How'd you distribute your miners around the house? Before I shut most of it down, I had them all in a single room, w/ an industrial fan blowing air in from the window (& the rest of that section sealed off that wasn't being used by fan), & then it would exhaust out of the top of the window. Bottom was opened as high as needed for the fan, top was open about 2 inches. They used four different circuits. One was in the room itself, one was from a second bedroom that also had my "main" computer in it (so I only used about 700 watts on that one), the third and fourth were from the master bedroom. Ranged from around 1200-1400 watts draw (besides the one room), depending on the temperature outside. When I got enough stuff to need to use the 2nd circuit, I was using a 15 foot, 16 gauge extension cord that ended up having the plug melted out, lol. After that I bought three 30ft 12 gauge extension cords.... think they were like $60 each. Also need to make sure your surge protector uses at least 14 gauge cord (w/ the assumption that the power supply cord is 10ft or less). |

Just buy the coins instead fellas. more profitable.
... or if you don't want to buy the coins, don't buy anything at all. Just like ASICs, this 'leased' mining is way overpriced. lol, they wouldn't be selling it if they could make more by using it themselves. I'd be shocked if cryptsy isn't getting its mining power from ghash.io as well. I'm pretty sure they have > 50% of the mining power, they're just doing a good job of disguising it.... re: can't you mine on different pools with cex now? But as to the actual prices, if Cryptsy doesn't a) shutdown, or b) isn't full of shit about the "lifetime" contract (which I'd say should be at least 3 years), the Cryptsy price is a better deal. After next difficulty increase, CEX maintenance costs are probably going to be near 50%? The thing is, I wouldn't be surprised if Cryptsy ended that "lifetime" contract as soon (maybe a month or two later, to throw off suspicion) as ghash.io's maintenance costs exceeded profit. Then again, you'd imagine they'd be using more energy efficient equipment by then, so who knows.. |

about 12 cents
12 cents seems very cheap. Its about 22 or more in Europe, is that from some great resource Texas has like fracking gas or nuclear? Rig setups like this explain why btc difficulty doesnt go down. Ever been tempted to turn it on an alternate sha256 coin for 5 mins 12 cents is a lot in Texas. You should be able to get much cheaper for commercial location? Residential where I'm at used to be ~7.5c per kwh, now it's around 8c, but natural gas prices have been going down since 2008 (about 25% in total when comparing seasons).. the biggest commerical plan here is lower than 5c ed: Commercial rate has to pay sales tax on it, UNLESS the electricity is used to make the product... which I guess would be the case here? lol. |

Hey guys.. anyone have any extra GH/s to point to a new pool for little while? Wanted to see how it holds up. Server is hosted in Atlanta, GA - 2 CPU - SSD drives - Gigabit connection. I only have one S1 on it now, but more are on order. Anyone care to give me some ping stats? http://squashpool.com:9332/static/108.61.192.121:9332 500 packets, hetzner in frankfurt, de: 115.3ms avg, 0% ploss colocrossing in buffalo, ny: 43.1ms avg, 0%ploss incero in seattle, wa: 24.3ms avg (19.5ms low, 263ms high, standard deviation 14.2), 1% ploss also look at squashpool.com:9332/pings (ed2: nm, looks like you have that disabled with the modded ui) |

23 0 0 07 0 0 15 1543 3098 Traffic is fine w/ that few connections. Like the other person said, it'll only shoot up if someone starts downloading the blockchain from you... I rebooted my system to install 14.04 and it has been up for 4 days + 2 hours (98 hours) so far. It has 206.9GB total uploaded, but some of that is dogecoin related. Probably about 175GB from bitcoin, that's with 550-700 connections. It'll hit up to 105MB/s upstream when a new block hits the network (which in that case means I had too many peers downloading it from me, but that's happened very few times, normally it maxes at around 50-70MB/s). If nobody is downloading the blockchain from me it's usually around 500KB/s or less (transactions). (ed: after watching dstat for a bit, it averages out to around 1MB/s except for when there is a new block... I suspect there are at least a few people downloading the blockchain at nearly every point, though... just maybe at 100kb/s or so..) |

Were you able to get it going at a decent speed, merge mining all those coins? Bitcoin probably runs a lot faster than I remember it because of client improvements, but a lot of those alt-coins use ancient clients.. |
|
|
|
Yeah, I used to have passwords with !@#$%^&*() in them and it wouldn't work. Just use letters and numbers.. |

Is there a notable difference when using a ssd vs hdd? It's better to use one for the blockchains and os? Much faster/ effects hw latencies how much? Would you advise someone running a private p2pool node to buy one?
Thanks!
Yes it appears to have a big impact on latency. I don't think it matters much for the OS but it does matter for the block chains. Thanks! Do all of these coins have the "datadir=" option like bitcoin? I guess I could just check... Yeah, I'd say all of them except perhaps the first half a dozen or so... a lot of them just copy the source & only modify block times, confirmations, coins rewarded, etc... But even for those that actually do change something meaningful, there's no reason to remove the datadir option. That's been in the bitcoin source for at least two years.. |

If the only way out is a reindex, it probably isn't slow nodes. Otherwise, you should be able to restart it and most of the time get at least a few blocks...
You could always try it with maxconnections=1, connect=5.9.24.81, and see if it downloads any then. I always just connect to one node when I have a significant amount of blocks to catch up on..

It'll surely have problems once you have more than a couple of people on there... just look at p2pool.org, etc.. It's not designed well for multiple ppl with how it handles the work requests.... when I had 10+ ppl on my Bitcoin p2pool, it'd take around 50-100ms before it got to the last person and that's with having it set at 5000 maxblocksize (cutting out most of the transactions)... not to mention the i7-2700k, 32gb of RAM w/ blockchain in ramfs. Try using two different difficulty settings and check the log and see what the time difference is between the two work requests.. but while we're on the topic of VPS', wable.com (incero) option #3 is sweet for $8 a month. can mix and match how you like & swap between dallas and seattle at will.. http://www.speedtest.net/result/3480771499.png from the seattle location (it still resolves the IP to Dallas, re: Seattle being 1750mi away) If what you say is true, then I'll be disappointed. But I'm going to try it anyhow... and if nothing else, use it for myself. I'd be happy if I got too many users. BTW I got my VPS for $30 a year. M Yeah, I have seen some for that cheap... like that ramnode thing or whatever I posted here earlier. You can find lots on lowendtalk or lowendbox.com... but I haven't found one where you can move it between Seattle and Dallas whenever you want  I'm damn near certain it'll be too slow if you allow all the transactions... I'd think w/ $30 a year it's probably just 2 or 3 cores? If you cut out all the transactions it might be OK My box is showing Xeon L5520 @ 2.267GHz 8 cores. I'm using the recommendations in the "p2pool FUD" thread to limit transactions. I'm not allowing all in. I tweaked things a bit to get it to be stable. The alt coins will use way too many connections and hence resources if I let them, I had to lock them down quite a bit. M Hm, I'm guessing those are shared cores, though? You'll be alright though if you limit the transactions a lot, from my experience that's essentially what causes those huge delays on work being distributed... & the slower your computer is going & the more people on it, the worse it gets.. (uh... see p2pool.org, *cough*) I did finally figure out what was messing up my bitcoin pool. I was one of the reserve pools for MacMiner (?) or something like that.... so even tho those people may not have ever hit my pool, it was still pulling work requests (probably shouldn't have been doing that, but maybe some flaw in the software) |

Probably got zapped as an orphaned or DOA share by p2pool... the whole efficiency thing
Same old thing huh? I must say things seem better on that that front than it used to be. Since I've returned to p2pool I've only gotten one orphaned share. Are you still mining bitcoin or have you moved on? What was it noglegg, is that right? Nevermind I see it in your profile info.... Yeah, haha. I haven't mined bitcoin in just about a year now. Maybe about a month before GPU mining really hit the skids, so I could get rid of some of my video cards while the prices were still decent. I didn't do anything at all for 3-6 months, then I started messing with CPU based "shitcoins" & for several months there it was actually profitable to buy dedicated servers and just mine CPU coins off of them.. not anymore, but... Now I just mess with dogecoin, mostly because I'm too lazy to sell my hardware. It makes about $250 a month, $100 of that going to electricity (thx 7c/kwh). .. and I've always liked to run the pools to try and get the highest efficiency rate |

We found a block about an hour ago but it doesn't show up in the last blocks list. If you go to p2pool.info it's in that list and we did get paid. I was just wondering why it's not in the list on the local nodes page?
Probably got zapped as an orphaned or DOA share by p2pool... the whole efficiency thing Sorry, what do you mean by Node peers 10? And difficulty? Please be more detailed. I guess he's telling you to set the outgoing connections to 10..... which is smart if you aren't allowing incoming connections (eh, well, it's better to use --p2pool-node and hand pick them) |
