I set up a v2ray server on AWS, yesterday I setup the client version on Mac Mini and tested using command line:
curl -x socks5://127.0.0.1:1080 http://www.google.com
The Mac version tested OK, returned html code of google page.
However, when I tried the Ubuntu version that I downloaded with the bash command, and used the same config.json, it did not work.
A test of Google got stuck and returned nothing. A test of Baidu returned wtih right html code immediately.
