The example of using curl to talk to bitcoind on the wiki works with 0.6.3, does not work with git HEAD:
```
 curl --user user --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getinfo", "params": [] }'  -H 'content-type: text/plain;' http://127.0.0.1:8332/
```
git head gives: curl: (52) Empty reply from server

rpcssl=1 was set in the bitcoin.conf, so bitcoind was expecting a https connection.

From #10218 (comment)

Authentication is not optional. Configuring it yourself is optional, but bitcoind never accepts RPC connections without explicitly or implicitly configured username/password.

If you didn't add user and pass in bitcoin.conf, you can use default from file /root/.bitcoin/.cache. For example: curl --user __cookie__:96fea535b009e62ddffe1c6f5090c50396d17e7f96d0b0a75eb580bdd1771d29 --data-binary '{"jsonrpc":"1.0","id":"curltext","method":"getinfo","params":[]}' -H 'content-type:text/plain;' http://127.0.0.1:8332
