NAME

       CURLOPT_SOCKS5_GSSAPI_NEC - socks proxy gssapi negotiation protection

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SOCKS5_GSSAPI_NEC, long nec);

DESCRIPTION

       Pass  a  long  set  to  1  to  enable or 0 to disable. As part of the gssapi negotiation a
       protection mode is negotiated. The RFC1961 says in section 4.3/4.4 it should be protected,
       but  the  NEC  reference  implementation  does  not.   If  enabled, this option allows the
       unprotected exchange of the protection mode negotiation.
