```
Repeat the above process (re-initialising the node) in order to run the Eth Protocol test suite again.
#### Eth66 Test Suite
The Eth66 test suite is also a conformance test suite for the eth 66 protocol version specifically.
To run the eth66 protocol test suite, initialize a geth node as described above and run the following command,
replacing `<enode>` with the enode of the geth node:
```
devp2p rlpx eth66-test <enode> cmd/devp2p/internal/ethtest/testdata/chain.rlp cmd/devp2p/internal/ethtest/testdata/genesis.json
