    "run_type": "client",
    "local_addr": "<local_addr>",
    "local_port": <local_port>,
    "remote_addr": "<remote_addr>",
    "remote_port": <remote_port>,
    "password": [
        "<password>"
    ],
    "log_level": 1,
    "ssl": {
	"verify": true,
	"verify_hostname": true,
	"cert":"",
	"sni":"",
	"alpn": [
            "h2",
            "http/1.1"
        ],
	"reuse_session": true,
        "session_ticket": false,
        "curves": ""
    }
}

Run

sudo systemctl start trojan

Then you can use the proxy with socks5://<local_addr>:<local_port>

Use proxychains

Add socks5 <local_addr> <local_port> at the end of file.

# Example
