1 2014-09-17 00:02:05 <earlz> Does the stratum protocol control the ntime mined for a block?
2 2014-09-17 00:14:10 <Luke-Jr> earlz: no, it's left entirely undefined
3 2014-09-17 00:15:14 <earlz> So, could a malicious miner mining at a pool possibly do timestamp manipulation?
4 2014-09-17 00:15:22 <earlz> (assuming he actually mined the block, of course)
5 2014-09-17 00:15:51 <earlz> Well, not just stratum, but also getblocktemplate
6 2014-09-17 00:16:14 <earlz> I notice there is a capability for timestamp that appears to always be enabled. I wonder if pools would handle if that was not enabled
7 2014-09-17 03:04:28 <gmaxwel> hmm
8 2014-09-17 03:04:34 <gmaxwel> everyone drunk here?
9 2014-09-17 03:04:35 <gmaxwel> :)
10 2014-09-17 03:05:55 <lifeofcray> yes
11 2014-09-17 03:17:00 <earlz> working on a glass of jack and coke, so yes
12 2014-09-17 04:37:48 <lechuga_> sipa: any chance you're up?
13 2014-09-17 07:00:24 <coryfields> wumpus: I'm retarded, my PR does the same thing as sipa's. just ignore.
14 2014-09-17 07:01:13 <wumpus> well at least you agree with his approach then :)
15 2014-09-17 07:01:31 <coryfields> sipa: ping. let me know what your next step is (re #4899) and I'll help out
16 2014-09-17 07:01:52 <coryfields> heh yea, it's funny how similar they ended up being
17 2014-09-17 07:02:27 <coryfields> i set out tonight to nuke that boost dependency and that was the result. should've checked the current PR's again first.
18 2014-09-17 07:47:59 <sipa> lechuga_: this chance is nonzero
19 2014-09-17 07:48:22 <sipa> gmaxwell: mildly
20 2014-09-17 08:09:11 <sipa> coryfields: next step? getting it merged would be nice...
21 2014-09-17 08:19:26 <coryfields> sipa: heh
22 2014-09-17 08:19:59 <coryfields> sipa: i assumed your intent was to drop key.h from the script lib
23 2014-09-17 08:20:26 <coryfields> that was what i was working on with #4934, anyway
24 2014-09-17 08:32:19 <sipa> coryfields: right, that too
25 2014-09-17 13:10:48 <jgarzik> saivann, https://bitcoin.org not working here
26 2014-09-17 13:12:34 <michagogo> Hm, same here
27 2014-09-17 13:12:54 <michagogo> ACTION checks http://isup.me/bitcoin.org
28 2014-09-17 13:13:09 <michagogo> Not pinging, either
29 2014-09-17 13:15:22 <saivann> Sigh, probably one of these strong DDoS attacks again, let me check..
30 2014-09-17 13:19:06 <saivann> Yes, 10gbps DDoS attack,Black Lotus does not protect us against those, they nullroute the IP until the attack is under 10gbps and then automatically reenable the IP
31 2014-09-17 13:23:41 <phantomcircuit> saivann, srsly?
32 2014-09-17 13:23:56 <timothy> who is black lotus?
33 2014-09-17 13:24:06 <saivann> phantomcircuit: We've had many of these recently
34 2014-09-17 13:24:18 <phantomcircuit> no i mean the 10gbps limit
35 2014-09-17 13:24:26 <saivann> timothy: https://www.blacklotus.net/
36 2014-09-17 13:24:52 <saivann> phantomcircuit: Yes sure, otherwise you need to pay the 2500$ setup fee + 500$ / month for 20gpbs
37 2014-09-17 13:25:11 <timothy> Global terabit-scale network with 480 Gbps of active DDoS mitigation capacity
38 2014-09-17 13:26:23 <Eliel> ok, who benefits from dropping bitcoin.org? Sounds like simply a nuisance level attack.
39 2014-09-17 13:38:16 <michagogo> Eliel: pretty much
40 2014-09-17 13:38:26 <michagogo> Many attacks of the sort are.
41 2014-09-17 13:38:36 <michagogo> Freenode's a good example...
42 2014-09-17 13:40:07 <michagogo> (also, TIL BlackLotus takes bitcoins via BitPay)
43 2014-09-17 13:42:54 <NewLiberty_> bitcoin short side investors may benefit. Its a black eye, nothing fatal but may make some news.
44 2014-09-17 13:53:08 <phantomcircuit> saivann, so you're not using one of their dedicated boxes?
45 2014-09-17 13:53:14 <phantomcircuit> they bill for bandwidth differently for those
46 2014-09-17 13:53:28 <phantomcircuit> afaict it's a much much better deal
47 2014-09-17 13:53:38 <phantomcircuit> even if you just use it as a reverse proxy
48 2014-09-17 13:54:08 <timothy> using cloudflare should help
49 2014-09-17 13:54:17 <saivann> phantomcircuit, we are indeed using their dedicated server, I think that's what you're doing too
50 2014-09-17 13:54:34 <saivann> timothy: AFAIK, Cloudflare 20gbps protection isn't cheap either
51 2014-09-17 13:55:41 <timothy> well, but you have most than one ip (cdn)
52 2014-09-17 13:55:45 <timothy> more(
53 2014-09-17 13:56:02 <timothy> so it's not so easy to ddos multiple ips
54 2014-09-17 14:00:52 <saivann> The attack just ended
55 2014-09-17 14:01:31 <saivann> timothy, I'll check with Black Lotus but I'll surely be considering other options too at this point.
56 2014-09-17 14:05:19 <saivann> For the record, I've just got more detailed data and what we're dealing with is strong UDP flood attacks that seems to be easily scaling at will.
57 2014-09-17 14:09:18 <phantomcircuit> saivann, unfortunately generating a massive udp flood is pretty easy
58 2014-09-17 14:10:33 <phantomcircuit> saivann, huh
59 2014-09-17 14:10:43 <phantomcircuit> i wonder if they changed their pricing structure
60 2014-09-17 14:11:38 <timothy> yes, botnet is a bad plague
61 2014-09-17 14:11:47 <phantomcircuit> oh nvm i see
62 2014-09-17 14:11:57 <phantomcircuit> at 20gbps you'd go over the clean traffic allotment in about an hour
63 2014-09-17 14:12:06 <phantomcircuit> that's pretty lame
64 2014-09-17 14:13:54 <saivann> I often hear people not recommending / trusting CloudFlare, is there some good arguments against using them?
65 2014-09-17 14:14:20 <saivann> Ah, the attack started back again..
66 2014-09-17 14:14:50 <timothy> we use cloudflare without many problems
67 2014-09-17 14:14:58 <phantomcircuit> saivann, they have your private key for https for one
68 2014-09-17 14:15:24 <timothy> forum login is not in plain text iirc
69 2014-09-17 14:15:37 <phantomcircuit> and in general their "web 3.0" startup feel isn't a great security indicator
70 2014-09-17 14:16:45 <phantomcircuit> and personally the fact that someone ddos'd intersango and then showed up on irc telling me to use cloudflare
71 2014-09-17 14:16:46 <phantomcircuit> well
72 2014-09-17 14:16:55 <phantomcircuit> that is quite possibly the biggest possible red flag
73 2014-09-17 14:19:35 <saivann> phantomcircuit: On the other hand, do you know what DDoS service we could use that would deal with our current attacks at a decent price (I'm not sure Black Lotus would succeed at 1000S/month)
74 2014-09-17 14:20:03 <phantomcircuit> saivann, not really no
75 2014-09-17 14:20:15 <phantomcircuit> protecting against ddos attacks is mad expensive
76 2014-09-17 14:20:27 <phantomcircuit> bandwidth is like $1/mbps
77 2014-09-17 14:20:37 <phantomcircuit> so their 480gbps is at least 480k/month
78 2014-09-17 14:20:44 <saivann> I don't want to waste the Foundation's money only on DDoS attack prevention
79 2014-09-17 14:21:08 <phantomcircuit> saivann, it's kind of a catch 22
80 2014-09-17 14:21:28 <phantomcircuit> the best protection tends to be limiting attackers information on how much bandwidth is available
81 2014-09-17 14:21:41 <phantomcircuit> since they will usually give up pretty quickly if their attack fails
82 2014-09-17 14:21:52 <phantomcircuit> but if they know you will run out of bandwidth quota after an hour
83 2014-09-17 14:21:56 <phantomcircuit> they keep going
84 2014-09-17 14:30:31 <bsm117532> Hi folks, I would like to use bitcoin with a newer libdb, in the interest of future maintenence. libdb4.8 is not included in most distributions now, it's so old. But compiling with newer libdb, bitcoin refuses to even create a new wallet.dat file.

105 2014-09-17 16:10:51 <RJ2> anyone know of a client-side JS lib that can validate a wallet address? (checksum/whatever)

111 2014-09-17 19:09:09 <aukaicue> what determines whether a rescan gets automatically run during bitcoin-qt start? (with -rescan flag not being passed)
112 2014-09-17 19:10:34 <sipa> aukaicue: the wallet stores up to what point in the chain it is synchronized
113 2014-09-17 19:12:25 <aukaicue> sipa, im loading up older wallets, and Im noticing a case where a rescan is needed but its not automatically being run.
114 2014-09-17 19:13:02 <sipa> how old?
115 2014-09-17 19:13:24 <sipa> very old software did not correctly write this marker
116 2014-09-17 19:13:51 <aukaicue> not sure if this is normal behavior, or something to draw attention to. Im thinking it is caused by the wallet needing to be rebuilt, and then the app proceeding to load the new wallet without doing a rescan.
117 2014-09-17 19:14:50 <aukaicue> sipa, if its from an old version that doesnt have the market, wouldnt that be a case to trigger a rescan?
118 2014-09-17 19:15:07 <sipa> the market?
119 2014-09-17 19:15:18 <aukaicue> sorry, marker
120 2014-09-17 19:15:45 <sipa> there have been buggy versions that incorrectly wrote the marker
121 2014-09-17 19:19:34 <aukaicue> sipa, ok, thanks for helping me understand.
122 2014-09-17 19:37:46 <wallet42> anyone tried out toshi.io?
123 2014-09-17 19:47:45 <seangilligan> Hello
124 2014-09-17 19:50:55 <nullbyte> evening
125 2014-09-17 19:50:56 <seangilligan> I'm happy to see init scripts for upstart and systemd making their way into the repository
126 2014-09-17 19:50:57 <seangilligan> https://github.com/bitcoin/bitcoin/issues/4124
127 2014-09-17 19:51:13 <seangilligan> https://github.com/bitcoin/bitcoin/pull/4611
128 2014-09-17 19:51:59 <seangilligan> I've looked around a little and can't find anything very informative/definitive about efforts to create an Ubuntu (debian) package for bitcoind -- where should I go to look for information on this?
129 2014-09-17 19:52:28 <seangilligan> (There is an existing package in a PPA repo, but it doesn't have init scripts yet nor can I find the source to the package)
130 2014-09-17 19:53:33 <aukaicue> seangilligan, https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
131 2014-09-17 19:55:15 <seangilligan> Thanks!
132 2014-09-17 19:56:05 <nullbyte> seangilligan, if you click through to view the package details, you'll be able to see they use a tarball of 0.9.2.1 to generate the package: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin/+packages
133 2014-09-17 19:57:28 <seangilligan> Is there any known effort to update it with the upstart init scripts?
134 2014-09-17 20:04:19 <nullbyte> not sure, most probably not
135 2014-09-17 20:32:57 <seangilligan> Would it makes sense to create an Issue on Github for this?
136 2014-09-17 21:04:53 <nullbyte> Yes
137 2014-09-17 21:28:41 <Sapee> I have read about the attack to Bitcoin.org today, please try Cloudflare Pro plan (20$ monthly only)
138 2014-09-17 21:28:52 <Sapee> The actuall host has a ping of 170ms
139 2014-09-17 21:29:31 <Sapee> Cloudflare has stopped >300Gbps UDP attacks
140 2014-09-17 21:34:36 <gmaxwell> Sapee: There is no such attack. Traceroute... you're seeing some issue closer to your ISP.
141 2014-09-17 21:34:54 <gmaxwell> The internet is like that sometimes... intermediary links get clogged for unrelate reasons.
142 2014-09-17 21:35:23 <sipa> i can reach bitcoin.org with 29ms latency
143 2014-09-17 21:35:48 <michagogo> Minimum = 224ms, Maximum = 348ms, Average = 263ms
144 2014-09-17 21:36:05 <michagogo> It really depends on where you are
145 2014-09-17 21:37:12 <michagogo> Getting 150ms from a box in the uk, I think
146 2014-09-17 21:38:13 <yiffening> 13ms average here
147 2014-09-17 21:39:03 <l_l_l_l_l> if this channel was busier this could become a DDOS :P
148 2014-09-17 21:39:45 <kdomanski> funny, how often after DDoS on a Bitcoin site someone comes over and starts pitching Cloudflare
149 2014-09-17 21:40:29 <yiffening> but cloud!
150 2014-09-17 21:41:42 <gmaxwell> 'funny'
151 2014-09-17 21:49:07 <Sapee> Ah, i am not related with Cloudflare, I read this http://www.cryptocoinsnews.com/bitcoin-org-under-ddos-attack/
152 2014-09-17 21:49:31 <Sapee> I am a Bitcoin Core translator (Spanish), look in Transfinex
153 2014-09-17 21:49:55 <Sapee> Thanks for the time, thanks Gmaxwell and thanks Bitcoin
154 2014-09-17 22:10:55 <seangilligan> Thanks again, @aukaicue and @nullbyte
155 2014-09-17 22:11:16 <seangilligan> I created Issue #4935: https://github.com/bitcoin/bitcoin/issues/4935
156 2014-09-17 22:16:49 <droark> sipa: What's the maturity status of libsecp256k1? If I were to fold it into a project of mine, would I be crazy? :)
157 2014-09-17 22:17:13 <sipa> droark: i make no guarantees; use at your own risk
158 2014-09-17 22:18:35 <droark> Thanks, and understood. Was just curious where it's at since commits seem to have slowed down a bit.
159 2014-09-17 22:22:10 <Sapee> Cloudflare response to the SSL private key problem: "We're looking at a possible solution to this because we have had some corporations voice a similar concern (regulatory issues). Based on what I know at this point, however, it would be limited to domains on an Enterprise plan."
160 2014-09-17 22:23:32 <Azelphur> I have an idea for implementing a "Sign in with Bitcoin" type mechanism on websites, with integration into Bitcoin clients that utilises message signing, here's a rough draft of how it would work. http://pastebin.com/VLD0q8Cx does anyone have any feedback on that? :)
161 2014-09-17 22:46:16 <seangilligan> Azelphur, how does your idea compare to BitAuth? https://github.com/bitpay/bitauth
162 2014-09-17 22:46:41 <Azelphur> seangilligan: never seen it before, does it work like gribble?
163 2014-09-17 22:46:56 <seangilligan> I've never heard of gribble
164 2014-09-17 22:47:11 <seangilligan> And only read about BitAuth a little
165 2014-09-17 22:47:17 <seangilligan> But curious about the basic idea
166 2014-09-17 22:47:22 <Azelphur> seangilligan: does this store private keys in the browser, and then have the browser sign messages?
167 2014-09-17 22:48:17 <seangilligan> I think it's intended for web services
168 2014-09-17 22:48:20 <Azelphur> looks like it does
169 2014-09-17 22:48:29 <seangilligan> But if they're being used in the browser, yes
170 2014-09-17 22:48:41 <Azelphur> seangilligan: mine is slightly different then, this has the private key in the browser, which is an interesting approach
171 2014-09-17 22:48:56 <Azelphur> my way would actually request a message be signed by whatever wallet you have installed (eg electrum, bitcoin-qt)
172 2014-09-17 22:50:10 <seangilligan> Your method has some advantages
173 2014-09-17 22:50:24 <Azelphur> maybe so, I just found this actually, it seems to have been discussed at length a while ago, http://sourceforge.net/p/bitcoin/mailman/message/29076261/
174 2014-09-17 22:51:21 <Azelphur> just seems to have never been implemented
