Have you tried it ? I haven't, but I assume that's what you'd do, as well as run with torsocks. Make sure your tor daemon is running. See the README for some tor info.
Direct monero client to sigaint's public TOR node?
http://monero7tukbkxn57.onion/
How do I use this? It's pretty straightforward, you just point your Monero client at monero7tukbkxn57.onion on port 18081. There are several thin-clients you can run ranging from console ones to graphical ones. For a list go here. The developer guide for the RPC is here.
How do I use this specifically with simplewallet? simplewallet --daemon-address monero7tukbkxn57.onion:18081
Sigaint doesn't provide tutorials on how to configure network setting on Monero client. Thanks.
