Test plan: |
|
- Start bitcoind's with different proxy configurations |
|
- Use addnode to initiate connections |
|
- Verify that proxies are connected to, and the right connection command is given |
|
- Proxy configurations to test on bitcoind side: |
|
- `-proxy` (proxy everything) |
|
- `-onion` (proxy just onions) |
|
- `-proxyrandomize` Circuit randomization |
|
- Proxy configurations to test on proxy side, |
|
- support no authentication (other proxy) |
|
- support no authentication + user/pass authentication (Tor) |
|
- proxy on IPv6 |
|
|
|
- Create various proxies (as threads) |
|
- Create bitcoinds that connect to them |
|
- Manipulate the bitcoinds using addnode (onetry) an observe effects |
|
|
|
addnode connect to IPv4 |
|
addnode connect to IPv6 |
|
addnode connect to onion |
|
addnode connect to generic DNS name |
