Title: New DDOS strategy being used? Repeated block count request? Post by: kano on March 11, 2013, 11:54:54 PM Firstly ... the IP address doing it was: 50.98.149.227
I'm running a modified bitcoind 0.7.0 (still) I got this error a few times in the log: Code: EXCEPTION: 11DbException I run multiple bitcoind, so I killed one off and restarted it. Then I watched the log for a while ... 6 minutes after I restarted bitcoind, I kept seeing: 03/11/13 23:27:42 getblocks 217373 to 00000000000000000000 limit 500 03/11/13 23:27:42 getblocks stopping at limit 217872 00000000000004b61fe2 But the block start number would climb up to current then start again back around 210373 Then repeat this process over and over continuously. My guess is that message is a request from a remote bitcoind? (not a bug in 0.7.0 asking for blocks it already has?) After a bit longer I got the above error I mentioned (when it tried to do a REORGANIZE) Anyway for the time I was watching it - (12 minutes) - I got 794 of these block list requests from the same IP address I listed above. I blocked the IP in my firewall and the requests all stopped immediately - so I obviously had the correct IP address. Title: Re: New DDOS strategy being used? Repeated block count request? Post by: kano on March 12, 2013, 03:10:58 AM Heh - well - at least I now know what that DB error was ... I'm running 0.7.0
It was the 0.7 vs 0.8 hard fork The hard fork occurred at block 225430 (after 225429) Title: Re: New DDOS strategy being used? Repeated block count request? Post by: misterbigg on March 12, 2013, 03:24:13 AM You were the canary in the coal mine.
