is made or until `monerod` is shutdown and restarted with only public
connections enabled.
Anonymity networks can also be used with `monero-wallet-cli` and
`monero-wallet-rpc` - the wallets will connect to a daemon through a proxy. The
daemon must provide a hidden service for the RPC itself, which is separate from
the hidden service for P2P connections.
## P2P Commands
@ -74,6 +79,35 @@ forwarded to `monerod` localhost port 30000.
These addresses will be shared with outgoing peers, over the same network type,
otherwise the peer will not be notified of the peer address by the proxy.
### Wallet RPC
An anonymity network can be configured to forward incoming connections to a
`monerod` RPC port - which is independent from the configuration for incoming
P2P anonymity connections. The anonymity network (Tor/i2p) is
[configured in the same manner](#configuration), except the localhost port
must be the RPC port (typically 18081 for mainnet) instead of the p2p port:
> HiddenServiceDir /var/lib/tor/data/monero
> HiddenServicePort 18081 127.0.0.1:18081
Then the wallet will be configured to use a Tor/i2p address:
> `--proxy 127.0.0.1:9050`
> `--daemon-address rveahdfho7wo4b2m.onion`
The proxy must match the address type - a Tor proxy will not work properly with
i2p addresses, etc.
i2p and onion addresses provide the information necessary to authenticate and
encrypt the connection from end-to-end. If desired, SSL can also be applied to
the connection with `--daemon-address https://rveahdfho7wo4b2m.onion` which
requires a server certificate that is signed by a "root" certificate on the
machine running the wallet. Alternatively, `--daemon-cert-file` can be used to
specify a certificate to authenticate the server.
Proxies can also be used to connect to "clearnet" (ipv4 addresses or ICANN
domains), but `--daemon-cert-file` _must_ be used for authentication and
encryption.
### Network Types
#### Tor & I2P
