Long: socks5-gssapi Help: Enable GSS-API auth for SOCKS5 proxies Added: 7.55.0 --- Tells curl to use GSS-API authentication when connecting to a SOCKS5 proxy. The GSS-API authentication is enabled by default (if curl is compiled with GSS-API support). Use --socks5-basic to force username/password authentication to SOCKS5 proxies.
