  5 2019-03-17T00:40:03  <gmaxwell> promag: right, but we shouldn't introduce a user exposed crasher over a spurrious test failure...
  6 2019-03-17T00:40:42  <gmaxwell> in any case, I'm not married to the idea of reverting it,  but that should be our _default_ response to serious bugs found in an RC esp when there isn't a really straight forward and clear fix.

 69 2019-03-17T11:06:33  <provoostenator> Today it finally happened: one of my nodes ran out of disk space. It's a "256" GB SD card holding the blocks dir.
 70 2019-03-17T11:06:53  <provoostenator>  accodring to df -h it's 234G with 222G used and 45M available (not sure how that math works...)
 71 2019-03-17T11:10:57  <provoostenator> Interestingly although it shutdown gracefully with "Error: Error: Disk space is low!", it appears too late to enable pruning, because it gives up during block rewinding.

 76 2019-03-17T11:21:25  <wumpus> in any case, if you're running out of space on 256GB, that means others will probably too areound the same time or already have
 77 2019-03-17T11:21:44  <provoostenator> That's why I mentioned it.
 78 2019-03-17T11:22:49  <provoostenator> checkblocks=1 and checklevel=0 doesn't help. Is it safe to just manually delete an old block file? Or will pruning fail if it can't find the file it wants to delete?
 79 2019-03-17T11:24:03  <gmaxwell> if you delete a blockfile you'll be resyncing.
 80 2019-03-17T11:24:46  <gmaxwell> you could try to compress up some non-bitcoin stuff to save you some space... or try to force a leveldb compaction.
 81 2019-03-17T11:25:54  <provoostenator> The sd card only contains blocks, the rest on a differnt volume wiht plenty of space
 82 2019-03-17T11:26:25  <provoostenator> But I figured I can just move more recent .dat files, which presumably won't be checked, and then let it prune and move them back?
 83 2019-03-17T11:26:29  <provoostenator> Or use a symlynk

122 2019-03-17T14:46:27  <Guest41284> following up from a comment on twitter ( https://twitter.com/tillneu/status/109877021273061376 ), we've been able to identify a significant (400+) number of peers on the p2p network that are currently engaging in a sybil attack.
123 2019-03-17T14:46:46  <Guest41284> peers of this type pretend to be running various versions of Bitcoin software, but are not. they respond with compact blocks handshakes, pings and pongs, but never respond to headers, get blocks, or inventory messages. the addr messages they push are stuffed with like-peers, and in general seem to be over represented in outgoing connections of normal nodes.
124 2019-03-17T14:47:06  <Guest41284> the current discovered peers are all on VPS hosts, carefully chosen to evade the logic which prevents connecting to multiple peers in the same /24. there's a sample of them here, representing GCE, AWS, DigitalOcean, and Hetzner. https://pastebin.com/raw/Q5wzqvg2

139 2019-03-17T16:13:27  <gwillen> hmmm, maybe we need stronger "IP diversity" heuristics than just limiting /24s?
140 2019-03-17T16:13:44  <gwillen> that's probably only workable in IPv4, but that will be live for awhile yet
141 2019-03-17T16:19:48  <gwillen> I guess with 15 different /8s represented in that list, it would be hard to catch in general
