Ok, that's why I get?  CrzyBilly, do you want to check this block's proofhash again please?

matches

hehe... eventually, it seems we're plowing straight through that harsh ground again

[twn]

Im on definetly right chain. Its good.

[crzybilly]

Just an FYI to all...

if you were caught off chain, and now you're back on... make sure you run checkwallet and repairwallet from debug window.

What is wrong and why I lose the right chain all the time?
I just resync the wallet from scratch yesterday.

the honest answer... because dev hasn't banned the people on the wrong chain

What do you mean?!?
Any advise how to fix that?

The only real way to fix this, is to have ambercoin01.mooo.com start banning connections.

I agree. But as I have posted I cannot connected to ambercoin01.moo0.com.  I get 0 connections and my wallet never syncs.  Maybe this node is overloaded and cannot support any more connections or there is some limit on the connections it will accept but whatever it is, if people cannot connect it is not a solution.

Also, you must set listen to 0 (listen=0) in your wallet .conf file or it will listen for other connections and accept them.  So you could wind up connecting to a bad node again and then off to a fork.  At least I believe that's how it works.

NO NO NO don't set that to 0... set it to 1 so that it can connect to ambercoin01

rpcallowip=127.0.0.1
rpcallow=localhost
rpcport=31981
listen=1
daemon=1
server=1
gen=0
addnode=ambercoin01.mooo.com

is my conf

Guys,

LISTEN=1 or 0 means at what port it must connect, if you have listen=1 and rpcpport=31981 then it will connect to port 31981. If you got Listen=0 it will not connect to rpcport 31981. It has nothing to do with your addnodes. If you make a config file with only the addnodes (so without deamon=1 and server=1 etc...) your wallet will still connect to the addnodes in you config file.

This is my config:
server=1
daemon=1
listen=1
rpcuser=user
rpcpassword=pass
rpcport=31981
addnode=108.61.173.201
addnode=188.163.90.183
addnode=88.198.100.148

everything is working fine here.

Notice I am connected to 3 nodes not even listed in my conf file?  

Here is the description of the -listen parameter from the wallet:

- listen Accept connections from outside (default: 1 if no -proxy or -connect)

I believe -listen=1 and addnode will result in connections other than the nodes listed in you conf file.

[crzybilly]

Well, during this whole time fixing wallets, I managed to get 20 blocks to myself...

[verycoinsuchlist]

I'm going to leave my firewall inbound rules locked down to ambercoin01.mooo.com (108.61.173.201).

Not sure how long I should run like that, but I figure at least long enough for these bad chains to stop.

exactly...

I believe -listen=1 and addnode will result in connections other than the nodes listed in you conf file.

and I suspect that as well... (yet, the -listen option is only used by the rpcserver, nothing to do with p2p which is the one needed for database syncing and stuff)

so the dev advising ONLY to use -connect is to be taken rather serious, as a startup option or in the conf file.
using addnode instead of connect immediately provided me with other nodes, some were way behind.
there seem to be no other peers appearing with -connect, tho.
for now I'd absolutely support using only the main node as a reference to sort out that mess once and for all.


and before THIS moves out of sight:

Just an FYI to all...

if you were caught off chain, and now you're back on... make sure you run checkwallet and repairwallet from debug window.

Very strange.

I just reloaded the blockchain posted 2 days ago, and re-synced with just the one node, no problem, but the last block is 599560, NOT 599640........

What's going on?

however, repost:

Maybe Dev can find a way to ban all of the old wallet versions?  I know other coins that have done this with a new wallet release.

I'm with it and after doing a full resync starting with your last checkpoint bootstrap upload and with just the connect to the main node, old peers.dat removed it synced ok after all... took some time, but went perfectly ok and it turned out that I've been on the right chain the whole time ...however, as by coincidence, I captured the updated blockchain files up to 599568 ...and put them in a zip archive, uploading them to zippyshare atm.
there's a md5 checksum inside that reflects the file state in the archive. I'll update this post as soon as upload is available

right now, avoiding every other client than the one at: 108.61.173.201 = ambercoin01.mooo.com  
seems to be the best solution to stay on the right chain until all clients that went away are as well back on the right chain again... anything else could feed this loop again and again whenever the network becomes thin at some end.

so, if you're not seeing the above proofhash @ getblockbynumber 599568, there's one thing to do to get back to the right blockchain:

- backup your wallet.dat (always do!)
- keep in mind, the archive as well has an ambercoin.conf so if yours is custom, rename it and make changes according the contained one
  if you don't have a ambercoin.conf, just ignore this line
- remove (or backup) 'database' and 'txleveldb' folders, 'blk0001.dat' and 'peers.dat' (to be on the safe side)
- get either the official bootstrap file from here: https://bitcointalk.org/index.php?topic=944408.msg13087230#msg13087230
      OR
- you can download a more recent version I captured @ block 599568 here:
  part1: http://www31.zippyshare.com/v/ej88U1BI/file.html
  part2: http://www31.zippyshare.com/v/iyia6kXg/file.html
- now unpack whichever of the archive versions you've got (either one version will do, the first might only take a bit longer) inside your datafolder, file structure of both versions are the same.
- start your wallet
- wait...
- it will hopefully connect sooner or later and eventually start syncing... first contact might take some time, but once this is through, it should sync ok.
- if syncing seems to be stuck (after having connected propperly and already received some blocks), a brief restart of the wallet
  should make it start receiving blocks again directly. and once you've had a successful connection with ambercoin01.mooo.com, the
  wallet should have no problems becomming reconnected immediately.

edit: 599444 confirming as well ok
edit: 599640 also ok (but that's not covered with my upload anymore)




I think it's not undue to stress this once more:

I believe -listen=1 and addnode will result in connections other than the nodes listed in you conf file.

and I suspect that as well... (yet, the -listen option is only used by the rpcserver, nothing to do with p2p which is the one needed for database syncing and stuff)

using addnode instead of connect immediately provided me with other nodes and some ot them were waaay behind.
there seem to be no other peers appearing with -connect, tho. ...which is what should be considered GOOD for the moment.
for now I'd absolutely support using only the main node as a reference to sort out that mess once and for all.


...can be done at anytime anyway without harm, but if you suspect your ballance might show some odd values, this will most likely fix the messed up display:

Just an FYI to all...

if you were caught off chain, and now you're back on... make sure you run checkwallet and repairwallet from debug window.

certainly all blocks being minted or mined AFTER tripping on a fork will of course stay on that fork... so, rolling back and resyncing to the main blockchain shows, they never existed in the first place. facing that case also means it would be a good time for the 'repairwallet' tip after syncing completed.

I am going to say it again and again and again.  YES, the right answer is for everyone to connect to ambercoin01.mooo.com and only ambercoin01.mooo.com until the bad fork fades away.  However, its not working for everyone for some reason.  I have tried many times in the last 2 days to connect to that node and I get 0 connects and I cannot sync my wallet.  I do not know why this is happening but until someone figures it out and fixes it there is no right solution.  wallets on a bad fork can go away but when they come back they could potentially cause a problem again.

Sorry for sounding frustrated - because I am frustrated - but it seems like we are just poking around right now not fixing the root of the problem.  We have bad nodes and people are connecting to them giving life to the bad fork.  I appreciate what you have done with the database and all but it looks like people are syncing to a good database then connecting to a bad node and going off on a fork ruining their wallet DB - requiring another reinstall and resync. 

Has anyone looked into he problem why some people cannot connect to ambercoin01.mooo.com?

[Fuzzbawls]

wow...been following along with this recent update and all the problems that have sprung up these past couple days. I'd like to clear up a bit of misinformation that has been tossed around regarding the conf/startup flags:

-daemon : "Run in the background as a daemon and accept commands". This actually has little effect when using the Qt GUI wallet.
-server : "Accept command line and JSON-RPC commands". This is what allows solo-mining when using an external mining program (cpuminer/ccminer/cgminer/etc).
-addnode : "Add a node to connect to and attempt to keep the connection open". Further nodes will be retrieved from these nodes and attempt to connect.
-connect : "Connect only to the specified node(s)". Says it all, ONLY nodes specified will be allowed to maintain a connection.
-listen : "Accept connections from outside (default: 1 if no -proxy or -connect)". This has EVERYTHING to do with the P2P network, and nothing to do with solo-mining or the RPC.

If your goal is to only connect to one node (whichever node that may be), set the following in your conf file:

Code:

listen=0
connect=<node_address>

listen is (or should) automatically be set to 0 whenever connect is used, but better to explicitly define it anyways. Another setting that is (or should) be set to 0 automatically when connect or listen are used, is upnp.

After doing a bit of code review, users should explicitly disable upnp in their wallets irregardless of your connection preferences as the current Amber source has not yet been updated to work with the recently patched miniupnpc versions (https://bitcoin.org/en/release/v0.11.1#fix-buffer-overflow-in-bundled-upnp).

As for why some people cannot connect to ambercoin01.mooo.com: the two very likely reasons this could be happening is that
1) the node has banned you for submitting invalid hashes. This ban will eventually be lifted, but you pretty much just have to wait it out.
2) the maximum number of stable connections for said node has been reached and further connections are being dropped.

[verycoinsuchlist]

Has anyone looked into he problem why some people cannot connect to ambercoin01.mooo.com?

certainly not too much into deep, and with only one side able to being inspected it might end up as well in guesswork...

...however I became aware that it might take some time, even if ALL steps to avoid hints of other clients than ambercoin01.mooo.com have been done, which are
  - removing peers.dat
  - no addnode at all in config, just connect=ambercoin01.mooo.com (or 108.61.173.201 if you will)
  - all old blockchain data being removed (database & txleveldb folders, blk0001.dat file)

sometimes I had the notion of that node simply dropping the connection over and over.... but after a while, might take half n hour or so, it got bound. it then lasted available since and used to become available immediately after a wallet restart, even with removing peers.dat. so, it might really be that node having too much to handle so it doesn't accept connections for that time... but, guesswork... yet, the above mentioned preparation eventually IS MANDATORY to let your wallet start receiving and accepting further blocks.

edit: one post above - which appeared while writing this - are some more comprehensive answers
thanx for the input! and well for the heads-up according to miniupnp!
