Long: socks5-gssapi-nec Help: Compatibility with NEC SOCKS5 server Added: 7.19.4 Category: proxy auth --- As part of the GSS-API negotiation a protection mode is negotiated. RFC 1961 says in section 4.3/4.4 it should be protected, but the NEC reference implementation does not. The option --socks5-gssapi-nec allows the unprotected exchange of the protection mode negotiation.
