I am trying to set up https://github.com/bitpay/insight for a forked version of Bitcoin.

To do this I need to modify the following

addNetwork({
  name: 'livenet',
  alias: 'mainnet',
  pubkeyhash: 0x00,
  privatekey: 0x80,
  scripthash: 0x05,
  xpubkey: 0x0488b21e,
  xprivkey: 0x0488ade4,
  networkMagic: 0xf9beb4d9,
  port: 8333,
  dnsSeeds: [
    'seed.bitcoin.sipa.be',
    'dnsseed.bluematt.me',
    'dnsseed.bitcoin.dashjr.org',
    'seed.bitcoinstats.com',
    'seed.bitnodes.io',
    'bitseed.xf2.org'

Everything there is pretty simple except for pubkeyhash, privatekey, scripthash, xpubkey, xprivkey and networkMagic.

I've used https://en.bitcoin.it/wiki/List_of_address_prefixes and http://lenschulwitz.com/base58 to figure out how to reproduce pubkeyhash privatekey scripthash but I still don't know how to get the xpubkey, xprivkey and networkMagic values listed above. How can I reproduce those values listed above from my Bitcoin client?

https://bitcoin.stackexchange.com/a/56639/61042 helped with xpubkey and xprivkey.

Now I just need help producing networkMagic. It's in the genesis block apparently but I have no idea how to read/decode it.

do you mean magic number ?

which is of 8 char long and starts at the blockfile ?

Found it using Hex editor of genesis block, thanks.

Go back to reading your dumb shit on /r/btc. These are the dnsseeds insight suggests I can use any. These are the ones Bitcoin Core project uses https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp - I can change them and compile with any I wish, or use another client.
