I have an Ethereum node that is not syncing to the Ethereum network. It is possible that there are some issues with the bootnodes - refer to geth does not sync out of the box .

How can I easily create a list of peers from my syncing node so I can copy and paste a list of admin.addPeer(...) command into my non-syncing node?

  • What about connecting the two? Shouldn't that make the "lonely" node discover the peers of the other one? – jeff Apr 13 '17 at 11:28

Run the following command in your syncing node to create a list of admin.addPeer(...) commands that you can paste into your non-syncing node:

function getPeers() {
  admin.peers.forEach( function(e) {
    console.log("admin.addPeer('enode://" + 
      e.id + "@" + 
      e.network.remoteAddress.substring(0, e.network.remoteAddress.indexOf(':')) + 
      ":30303');");
  }) 
}
getPeers();

Running the command above will create the following list of admin.addPeer(...) commands that you can paste into your geth console or geth attach command line to start your non-syncing geth node syncing:

admin.addPeer('enode://102f67188f247917f7961ccd073f41f969e071beef3161de81b64a2b438a5a551b1b6bf878838cdaa1ffad7b30a701f9b66cd407dd3f749725f2580979a6d814@223.72.84.91:30303');

// Paste the above lines into your non-syncing geth node command line

The script replaces the ports of the peers to 30303 assuming that this is the port the connected peers are listening on. Some of these will be correct, some will not be. But this is enough to kick-start your node syncing.

I'm looking forward to the next version of geth with this issue fixed.

See Reddit - Ethereum Wallet geth Client Not Syncing - Possible Problems With Bootnodes for instructions on inserting these admin.addPeer(...) lines into the geth attach or geth console commands for OS/X, Windows and Linux.

  • where do i run getPeers function, in geth console ? my net.peerCount is 0 and i dont know why – Axil Feb 13 '18 at 23:42
  • If it is Ropsten you want to sync to, use the list of admin.addPeer(...) commands at ethereum.stackexchange.com/a/39548/1268 . This may give you a connection to the network. After you have connected, you can run the getPeers() command if you want to copy and paste this in another geth instance. – Bokky WeAreAllAssange PooBah Feb 14 '18 at 4:10
  • Sad, I have 4 peers before running the above commands. Now ended with 0 :(. Can anyone give an updated peers list? – s k Oct 26 '18 at 7:21
