opera 不支持 socks 代理

只能另想办法，也许可以设置为系统代理（Gnome）

But anyway, this won't work with Opera, because it doesn't support SOCKS proxies. And that's kind of sad - or was, until I figured out a workaround. I installed tinyproxy (I like tiny), but it could just as well be Squid or Privoxy or some other HTTP proxy. It's set up on my home server. To prevent outside connections, I changed the "Listen" and "Allow" directives to "127.0.0.1". And I set up another tunnel in SSH - not dynamic, just a local tunnel from my work desktop to the home server on tinyproxy's port. And then I told Opera to use localhost as the HTTP proxy server.
