strMessage for masternode broadcast (which we sign and verify) looks like this currently:
[2001:1608:45:3::242:ac11:6]:199991464464536
?~}&?Q?S?Ǚ?q ?0??????O?I/Y?(
?f?jJF??m??bssknN??9鲜JXVs?ә?5T?8??????~70200
which I believe in some cases leads to "Got bad Masternode ping signature" errors and banning.
I propose to change the way strMessage is composed so that it looks like this:
[2002:82ff:c04:2:a90f:2261:43c4:2745]:1999514645552319591ec70225aacadfafa4ab5d21e87cdce641fd4030d029485434533c5e481578a9d471089fb5ec170200
Further more nDos for old masternodes is set to 0 to stop false positives (message still gets rejected though).

Funny enough ACK d705da7 |

heh, and node that passed me that message and was banned for doing so is mine, so I was pretty sure it's a legit one 😉 |

I've seen this bug and had no luck track it down. What is the mechanism for the bug using the signature? Is it some crazy encoding issue then? |
|
@evan82 yep, I guess so. Pushing raw data to string is not very intuitive and can give different results on different OSes I guess. My guess was that using string-yfied hash160 of pubkey serialization should give deterministic result regardless of OS type or version. Hopefully I was right :D |
