This copies the functionality of btcd for choosing the ports for the
HTTP client (for btcd) and server (for frontends). On testnet, the
following ports are used as default:
- btcd: 18334
- frontends: 18332
When running with the (currently disabled) --mainnet flag, btcwallet
will choose the following ports by default:
- btcd: 8334
- frontends: 8332
Both ports can be overridden no matter the chosen network using the -b
and -p flags.
