How to expose socks5 and http proxy with username and password in sslocal?

[kuolemaaa]

as title, how do I set it such that i connect to the sslocal via like socks5://myusername:mypassword@mysslocal ??

For SOCKS5, you need a separate JSON file to specify the username-password pairs. See https://github.com/shadowsocks/shadowsocks-rust#socks5-authentication-configuration.

HTTP basic auth is not currently supported. You might be interested in other implementations like https://github.com/database64128/shadowsocks-go.

Well, yes, but no...

sslocal -c config.json

currently shadowsocks-rust does not support authentication

This is a misleading error message leftover from before shadowsocks-rust gained SOCKS5 authentication support:

shadowsocks-rust/crates/shadowsocks-service/src/local/socks/server/socks5/tcprelay.rs

Lines 57 to 96 in 157cefa

	async fn check_auth(&self, stream: &mut TcpStream, handshake_req: &HandshakeRequest) -> io::Result<()> {
	use std::io::Error;
	let allow_none = !self.auth.auth_required();
	for method in handshake_req.methods.iter() {
	match *method {
	socks5::SOCKS5_AUTH_METHOD_PASSWORD => {
	let resp = HandshakeResponse::new(socks5::SOCKS5_AUTH_METHOD_PASSWORD);
	trace!("reply handshake {:?}", resp);
	resp.write_to(stream).await?;
	return self.check_auth_password(stream).await;
	}
	socks5::SOCKS5_AUTH_METHOD_NONE => {
	if !allow_none {
	trace!("none authentication method is not allowed");
	} else {
	let resp = HandshakeResponse::new(socks5::SOCKS5_AUTH_METHOD_NONE);
	trace!("reply handshake {:?}", resp);
	resp.write_to(stream).await?;
	return Ok(());
	}
	}
	_ => {
	trace!("unsupported authentication method {}", method);
	}
	}
	}
	let resp = HandshakeResponse::new(socks5::SOCKS5_AUTH_METHOD_NOT_ACCEPTABLE);
	resp.write_to(stream).await?;
	trace!("reply handshake {:?}", resp);
	Err(Error::other(
	"currently shadowsocks-rust does not support authentication",
	))
	}

What actually happened here is that either you forgot to configure your client to use the username and password, or all authentication methods advertised by your client were not supported by shadowsocks-rust.
