NXT :: descendant of Bitcoin - Updated Information

[davethetrousers]

I welcome any ideas and extensions for this task.

Great! I'd be very happy about something of that sort.

Some ideas:

• Using the admin peer data (e.g., here) of every node on the node list to find out roughly how many unique nodes there are in the network (parsing it all into one list/set, weeding out doubles, then count number)
• Somehow accessing network load figures of public nodes, which us admins would have to make available somehow (cronjob netstat/iftop to file on apache or similar); fetch all, then do some statistics
• Try to identify known zombies/perma-leechers/DDoSers of all nodes, collect IPs, do statistics of weird nodes vs. all nodes

about test net:

how many nodes are the minimum?
is it for permanent testing also longer term?
(later for this we could migrate the current vps node infrastructure step by step into the test net if we have enough NxT-user)

I don't know how many we'll need.
Could be for short or long time testing.

We should be careful about public announcing the IPs for these, don't want new users adding testnet to their well known hosts

I have no idea how to set up a Testnet!

I can give a bounty to whoever implement it - it is of great importance to be ready after 3rd Jan every change to run it first there.

Even know it would be good.

We already set up a small testnet to test Alias system before it went live.

All it takes is to install NXT running on a different port, for example 6874 6875 were used in that Alias system testnet.

and then nodes that take part in the testnet add each other to the config.

ah ok, every change to test there, understand.

Using portforward, a dyn DNS service and updating hallmark and address in the config on every IP change should work... Inconvenient, but doable.

I understood from CfB in discussions a week ago that this still wasnt good enough.  I guessed because it required correct reverse DNS lookup...
CfB, can you confirm if this is true?

NRS checks real address and address included into a hallmark. If they don't match the soft invalidates the hallmark. This is what used for acquiring real address - http://docs.oracle.com/javaee/6/api/javax/servlet/ServletRequest.html#getRemoteHost()

I know there was talk of it maybe last week? It's buried somewhere in the thread. Let me see if I can find it.

1000+ active peers here!  I wonder how many are Raspberry Pi.

There have been 26 downloads of my Pi package yet. I have no idea how many people have set it up themselves earlier. Probably not a whole lot.

nxtcrypto.org seems to be holding nice and strong throughout the DDoS.  I'd like to suggest that the admin install dokuwiki at some point instead of pointing to wikia.  dokuwiki is dead simple to install, maintain, and use.

Are you running it?  Any problems once it's going?  Is the Model B OK?  I'm ordering one tomorrow.

Who can setup an NXT Testnet?

I can once I get through all of these node deploys.

DGEX is back up and the coinmarketcap.com price moved up immediately.

I'll do one too

OK Im reading that..

Returns the fully qualified name of the client or the last proxy that sent the request. If the engine cannot or chooses not to resolve the hostname (to improve performance), this method returns the dotted-string form of the IP address. For HTTP servlets, same as the value of the CGI variable REMOTE_HOST.

OK well its still unclear if it tries to make sure it resolves claimed DNS's reverse lookup to the actual sending IP.

if  the myAddress field i web.xml is a DNS name, does the client reverse lookup, and then see if the source IP matches the reverse lookup?  Or does it simply see if the claimed name in myAddress resolves to the source IP address>

Running fine on Model B. I even got lucky once and forged a block on it

Yesterday I had it running for some hours without hickups. Now I just unlocked on the Pi once more to test overnight.

yes this is part of the plan!

It's up to Java implementation. Do http://remotenode.com:7874/nxt?requestType=getMyInfo and check value of "host".

This is bigger than the Dogecoin scam.

Nice try, China government!

It's factually correct. Nxt is bigger than the Dogecoin scam.

Doesn't mean Nxt is a scam
