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 RFC 1961 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.

DEFAULT

curl_easy_setopt(curl, CURLOPT_SOCKS5_GSSAPI_NEC, 1L);

curl_easy_cleanup(curl);
}
