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.

If enabled, this option allows the unprotected exchange of the protection mode negotiation.
