Java – why does my socks proxy code throw a socketexception: a malformed reply from the SOCKS server?

Why does my socks proxy code throw a socketexception: a malformed reply from the SOCKS server? I tried on urlconnection or other settings, but it didn't work The only useful thing - chilkat lib, but it's commercial So, how can I issue an HTTP request through the asocks proxy? Maybe there are some free LIBS?

For example, the code:

SocketAddress addr = new InetSocketAddress(proxy_ip,proxy_port);
    Proxy proxy = new Proxy(Proxy.Type.soCKS,addr);
    Socket socket = new Socket(proxy);
    InetSocketAddress dest = new InetSocketAddress("google.com",80);
    try {
        socket.connect(dest);
    } catch (IOException ex) {
        Logger.getLogger(CheckProxy.class.getName()).log(Level.SEVERE,null,ex);
    }

Throw exception:

java.net.socketException: Malformed reply from SOCKS server
at java.net.socksSocketImpl.readSocksReply(UnkNown Source)
at java.net.socksSocketImpl.connect(UnkNown Source)
at java.net.socket.connect(UnkNown Source)
at java.net.socket.connect(UnkNown Source)
at proxychecker.CheckProxy.socksCheck(CheckProxy.java:86)

Line 86 is "socket. Connect (dest);"

Solution

SocketException: Malformed reply from SOCKS server

SocketException: Malformed reply from SOCKS server

This indicates that you do not have a socks agent at all Maybe it's an HTTP proxy
