CURLOPT_FTPPORT(3)					     curl_easy_setopt options						CURLOPT_FTPPORT(3)

NAME

       CURLOPT_FTPPORT - make FTP transfer active

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FTPPORT, char *spec);

DESCRIPTION

       Pass a pointer to a zero terminated string as parameter. It specifies that the FTP transfer will be made actively and the given string will
       be used to get the IP address to use for the FTP PORT instruction.

       The PORT instruction tells the remote server to connect to our specified IP address. The string may be a plain IP address, a host  name,  a
       network	interface  name  (under Unix) or just a '-' symbol to let the library use your system's default IP address. Default FTP operations
       are passive, and thus won't use PORT.

       The address can be followed by a ':' to specify a port, optionally followed by a '-' to specify a port range.  If the port specified is	0,
       the  operating  system  will  pick  a  free port.  If a range is provided and all ports in the range are not available, libcurl will report
       CURLE_FTP_PORT_FAILED for the handle.  Invalid port/range settings are ignored.	IPv6 addresses followed by a port or portrange have to	be
       in brackets.  IPv6 addresses without port/range specifier can be in brackets.

       Examples with specified ports:

	 eth0:0
	 192.168.1.2:32000-33000
	 curl.se:32123
	 [::1]:1234-4567

       You disable PORT again and go back to using the passive version by setting this option to NULL.

       The application does not have to keep the string around after setting this option.

DEFAULT

       NULL

PROTOCOLS

AVAILABILITY

       Port range support was added in 7.19.5

RETURN VALUE

       Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.

CURLOPT_CAINFO(3)					     curl_easy_setopt options						 CURLOPT_CAINFO(3)

NAME

       CURLOPT_CAINFO - path to Certificate Authority (CA) bundle

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAINFO, char *path);

DESCRIPTION

       Pass a char * to a zero terminated string naming a file holding one or more certificates to verify the peer with.

       If CURLOPT_SSL_VERIFYPEER(3) is zero and you avoid verifying the server's certificate, CURLOPT_CAINFO(3) need not even indicate an accessi-
       ble file.

       This option is by default set to the system path where libcurl's cacert bundle is assumed to be stored, as established at build time.

       If curl is built against the NSS SSL library, the NSS PEM PKCS#11 module (libnsspem.so) needs to be available for this option to work prop-
       erly.

       (iOS  and  macOS  only)	If curl is built against Secure Transport, then this option is supported for backward compatibility with other SSL
       engines, but it should not be set. If the option is not set, then curl will use the certificates in the system and user Keychain to  verify
       the peer, which is the preferred method of verifying the peer's certificate chain.

       The application does not have to keep the string around after setting this option.

DEFAULT

       Built-in system specific

PROTOCOLS

       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE

       TODO

AVAILABILITY

       For  SSL  engines  that	don't  support certificate files the CURLOPT_CAINFO option is ignored. Refer to https://curl.haxx.se/docs/ssl-com-
       pared.html

RETURN VALUE

       Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
