I have been trying to get my Mist application to sync to the Ethereum network. I tried running geth directly also, screen shots below.

Blockchain not syncing

    Are downloading the ETH (hard-forked) or ETC (non-hard-forked) blockchain? If you are downloading the ETC blockchain, there are less nodes out there to sync with. – The Officious BokkyPooBah Aug 10 '16 at 8:17

    Hi, I am syncing with ETH blockchain. – Lismore Aug 10 '16 at 20:58

Are you downloading (syncing with) the block chain for the first time? If so, it will take some time due to the size of the block chain.

Just to make sure there is no connectivity related issue you can use wireshark and check whether peer discovery is working (packets are exchanged between your machine and the default geth bootstrap nodes:

// FrontierBootNodes are the enode URLs of the P2P bootstrap nodes running on
// the Frontier network.
var FrontierBootNodes = []*discover.Node{
    // ETH/DEV Go Bootnodes
    discover.MustParseNode("enode://a979fb575495b8d6db44f750317d0f4622bf4c2aa3365d6af7c284339968eef29b69ad0dce72a4d8db5ebb4968de0e3bec910127f134779fbcb0cb6d3331163c@"), // IE
    discover.MustParseNode("enode://de471bccee3d042261d52e9bff31458daecc406142b401d4cd848f677479f73104b9fdeb090af9583d3391b7f10cb2ba9e26865dd5fca4fcdc0fb1e3b723c786@"),  // BR
    discover.MustParseNode("enode://1118980bf48b0a3640bdba04e0fe78b1add18e1cd99bf22d53daac1fd9972ad650df52176e7c7d89d1114cfef2bc23a2959aa54998a46afcf7d91809f0855082@"),  // SG

    // ETH/DEV Cpp Bootnodes

// TestNetBootNodes are the enode URLs of the P2P bootstrap nodes running on the
// Morden test network.
var TestNetBootNodes = []*discover.Node{
    // ETH/DEV Go Bootnodes

    // ETH/DEV Cpp Bootnodes

  • Thanks This is not the first time syncing to the blockchain. Appreicate the code snippet. I will have a look in wireshark. – Lismore Aug 10 '16 at 20:57
  • Make sure you are using the same data directory otherwise geth will re synchronize. – Sebi Aug 10 '16 at 21:05

Finally found a solution

geth.exe removedb

which cleared the chain and then

geth.exe --fast --cache=2048

to resync
