Where to put the IP address of the entire node

My new altcoin is almost ready. I have a full functioning node, and I wonder how people will connect to it. That I have to do?

javascript – limit each node in a network created using networkD3 :: forceNetwork () with a specific color

Consider the following network, can nodes be delimited with colors based on a column in the MisNodes data frame? The forceNetwork function has the option to color the edges but not the edges of the node.

I will appreciate any suggestions

library (networkD3) 

# Load data

# Plot
forceNetwork(Links = MisLinks, Nodes = MisNodes,
        Source = "source", Target = "target",
        Value = "value", NodeID = "name",
        Group = "group", opacity = 0.8)

8 – Create a node from a web form submission

I tried to create a node from a web form submission in vain, using the second answer here: How to create a node from a web form submission?

The first answer I could make, the second, the one I really want, I couldn't. The steps:

  1. Module created (with Drupal console).
  2. Created a web form
  3. Driver added (email)
  4. MyWebformHandler.php was added (based on StackOverflow response)

It did not work.

Please notify.

The central Bitcoin node does not send outgoing connections only incoming traffic

My bitcoin core is not sending outbound connections. You are only getting incoming connections. Iv removed the entire node and then reinstalled it. Still I was just getting incoming connections. Iv verified the firewall configuration and the node is configured to receive incoming and outgoing connections. Does anyone know what the problem could be? Could you synchronize blockchain only with incoming connections?

7 – How to make the fields of a cloned node available in Rules

I have a rule that clones a node once it is checked. I can set certain parameters for this newly cloned node, but not all. I read in other publications that you must use a conditional rule to identify the type of node of that cloned node and then have access to all fields. But again not to "all" the fields. I want to set the text field of the cloned node "student's name" with the author's name, a text field in the user's profile. Many fields in the marked user profile are available, but not all.

8 – Twig: How to access multiple values ​​from the node reference field with number_format

I am adding fields to the array:

{% for item in content.field_notes | field_target_entity %}
   {% set field_component_pages = item.field_component_pages|view|number_format %} 
{% endfor %}

In my scenario, the value of item.field_component_pages | view is equal to "16", but when I convert it to number with number_format I get the value 1.

I presume the item.field_component_pages|view It is not a real value. How can I access the field_component_pages field correctly in this case?

design: shows two information in the tree node

In my web application I have a tree with each node with two states.

Nodes are circles linked together.

The status can be OK, KO or PARTIAL.

The first state is the "technical state" of the node.
The second state is the "functional state".

The functional state of the node depends on its technical state.

I need a way to show the two states (OK / KO / PARTIAL) so that users can quickly identify which nodes are in functional or technical state KO or PARTIAL.

A 2009 node synchronizes the entire bitcoin blockchain

In theory it can, since the rules of explicit consensus have not changed. However, in practice, it cannot be synchronized without some special modifications.

First, the network version is so old that no modern node software will accept connections from it. In addition, the format of the network messages has changed since the first version, so it now contains a message checksum. The first version of the Bitcoin client did not have a checksum for the messages. This difference in the network protocol will result in messages that make no sense to any of the nodes in a connection.

In addition to the network message change, the original Bitcoin client will not be able to find nodes to connect. It could only be connected only by using the discovery of IRC nodes that has since been disabled and removed. Therefore, you will need to specially build the peers.dat file so that you can find an equal to connect.

Finally, the original Bitcoin client will not be able to synchronize beyond the 2013 fork unless the number of BDB blocks is increased. Using the default settings, you will run out of locks when you arrive at that time and therefore will not be synchronized.

If you can avoid all these problems (for example, using special node software specifically to synchronize) and increase the number of BDB crashes, then the original Bitcoin client should be able to synchronize the current blockchain, although very slowly and possibly never You can synchronize with the tip. Towards the current point of the blockchain, it will probably take longer to validate a block than it takes to find a new block.

Several months ago I modified a version of Bitcoin Core to be compatible with Bitcoin 0.1.0 and then tried to synchronize it. The code for that is here. I stopped that experiment after a few days when I could only synchronize ~ 25,000 blocks.

network – How to know if my node is online (conflicting information)

I am really confused I am trying to configure a listening node. When I look at bitnodes.earn.com, it shows my node as offline when I search for IP, but when I run getconnectioncount returns a positive number and returns getnetworkinfo

  "version": 190001,
  "subversion": "/Satoshi:",
  "protocolversion": 70015,
  "localservices": "0000000000000409",
  "localservicesnames": [
  "localrelay": true,
  "timeoffset": -13,
  "networkactive": true,
  "connections": 20,
  "networks": [

      "reachable": true,

      "name": "ipv6",
      "limited": false,
      "reachable": true,
      "proxy": "",

  "relayfee": 0.00001000,
  "incrementalfee": 0.00001000,
  "localaddresses": [
  "warnings": ""

What's going on? How can I know if my node is really accepting connections? Is this because I am still downloading the chain? All I'm looking for is retransmit / retransmit my transactions.

javascript: js node variable injection in single response directly to client DOM

this is what i did
sending the JSX backward syntax directly to the client through express to inject the variable & # 39; foo & # 39; directly in the client's DOM (which you can see in the image below)

enter the description of the image here

Now what I want to achieve is,
to send the index.html file together with the injected variable that comes from the file where the server is written (node ​​/ express).
NOTE! Display engines are not allowed, it should be as simple as possible.
