Nope, there are no incompatible changes. I see that it happens sometimes with p2pool for different cryptocurrencies. Is the 7777 port available for connection?

By the way, new p2pool is coming soon.

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

Thanks for the quick reply!

I found the issue - it is that p2pool doesn't like the max connections setting...
I have it connecting to a local novacoin-qt now with the following novacoin.conf

Code:
rpcuser=bitcoinrpc
rpcpassword=IUSESOMETHINGELSE
daemon=1
server=1
[b]# maxconnections=16[/b]   <-- hangs p2pool, don't use

Hm... I have no idea why you've added this setting. It's P2P connections limit. Smiley

Quote
rpcuser=bitcoinrpc
rpcpassword=IUSESOMETHINGELSE

I recommend you to set a random RPC username/password and make sure that your 8344 port isn't available for incoming connections from the internet. We have enough skiddies who scans the novacoin network and trying to find p2pool users with opened RPC port.

Official repository is moved here:

https://github.com/novacoin-project/novacoin

My own repository (CryptoManiac/novacoin) will be available, but it's recommended to use official repository instead.

Since upgrading my proxy node on my Raspberry Pi to v0.4.4.6-nvc-12-gbafc8da-beta, I'm observing a behaviour I haven't seen before in debug.log:
getblocks 67859 to 00000000000000000000 limit 500
  getblocks stopping at limit 68358 d537d885299074f8efb1

  getblocks stopping at limit 69358 b0d680ecdd0e4d6984cc
You can see the getblocks looping, i.e. going up to 68859, then starting again at 65859. Since unfortunately it doesn't log IP I cannot see if it's always the same node requesting this.
When stopping & restarting the node , it stays normal for several days until I start seeing this again(happened about 5 times so far). Otherwise, the node seems to remain functional, i.e. forwarding blocks etc.
Anyone else seen this behaviour?

Hey everyone,

Just wanted to share some love regarding Novacoin.  I've been creeping these forums for months and there are very few that deserve a "pat on the back".  Many of you on here have given some great opinions regarding the coin and it's future and have helped me through some doubts.  In hindsight, I'm glad I've supported this coin and it's devs.

Keep up the great work guys.

I seen that many times on my cubie and I see this now on my VDS.

I don't think that it's the same node, I think this requests are coming from buggy nodes (< 0.4.4.5). The buggy client is able to see that network is on the longer chain currently, but unable to accept this blocks. That's why it tries to sync again and again with a randomly chosen node, bans it and then tries to sync from another one. This can cause some traffic or CPU overhead on normal node, but overall, it's harmless.

We'll add a special condition for incoming connections initiated from versions prior to 0.4.4.5. Roll Eyes

You can use a small patch to resolve this by yourself:

  • Core: Transaction index is replaced with unspent coins database, ~20% drop of size;
  • Core: Batch block connection during initial block download;
  • Core: Don't process PoS block coinbase in the ConnectBlock()/DisconnectBlock(), ~3-4mb smaller database size;
  • Core: Refactoring of Proof-of-Stake checkings code;
  • Core: Remove some redundant messages from debug.log output;
  • Core: Make stake related DoS checkings harder;
  • Core: Database code is updated, direct CCoins links approach is implemented to decrease count of worthless flush and copy events;
  • Core: Initial block download optimization, transaction hashes are cached now to make blocks validation faster;
  • Core: Multiple CChainDB instantiations were replaced with a single CBlockTreeDB instance;
  • RPC: gettxout and gettxoutsetinfo RPC calls added;
  • RPC: getblock and getblockbynumber RPC calls are now providing generator public key for proof-of-stake blocks.

32/64-bit Windows builds of 0.4.4.7 release were uploaded to sourceforge.

Installation packages:
[AMD64 | i686]

P2Pool is updated to support connections with v0.4.4.7 nodes.

sources | Win32 py2exe

Older versions won't be able to establish P2P connection with v0.4.4.7 client due to obsolete protocol version. So, if you are switching NVC client to 0.4.4.7 then you need p2pool update as well.

0.4.4.1 is unable to work correctly, you need to replace it with 0.4.4.5 or greater.

It seems that you have mined some blocks for the wrong chain. That's not a problem for stake blocks, because those inputs were recovered during synchronization process. With this recovered inputs you are able to find some valid blocks again. Smiley

Hello group!

I was hoping you could help me make contact with the creator of NOVAcoin?

We are hosting The Crypto Currency Convention in NYC on April 9th. We would like them to speak and promote NOVAcoin.

Our mission is to bring awareness and acceptance to all Crypto Currency and not just bitcoin.

Education and exposure is the only way we all win.

We are expert marketers and expect 1500-2000 attendees.

If you could please forward a message or somehow make an introduction, it would be greatly appreciated and productive.

Thanks!
