Which of the following SSH commands will start a SOCKS proxy server on the local system?

The command 'ssh -D 2000 [email protected]' binds a SOCKS4/SOCKS5 proxy listener on local port 2000 and forwards all proxied connections through the SSH tunnel to the remote server at 10.10.10.20. Applications configured to use localhost:2000 as a SOCKS proxy will have their traffic transparently routed through the encrypted SSH session.

The -R flag creates a remote port forward, binding a port on the remote SSH server (9762) and forwarding inbound connections on that port back to localhost:3576 on the client - not a SOCKS proxy.

The -L flag with a bind address (0.0.0.0:7324) creates a static local port forward that maps a specific local port to a single specific destination (10.10.10.200:80), which is not a dynamic SOCKS proxy.

This -L command also creates a static local port forward bound only to the loopback interface (8895) forwarding to a single fixed destination, not a SOCKS proxy capable of dynamic routing.
