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: + +.nf + eth0:0 + 192.168.1.2:32000-33000 + curl.se:32123 + [::1]:1234-4567 +.fi + +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. +.SH DEFAULT +NULL +.SH PROTOCOLS +FTP +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/old-server/file.txt"); + curl_easy_setopt(curl, CURLOPT_FTPPORT, "-"); + ret = curl_easy_perform(curl); + curl_easy_cleanup(curl); +} +.fi +.SH AVAILABILITY +Port range support was added in 7.19.5 +.SH 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. +.SH "SEE ALSO" +.BR CURLOPT_FTP_USE_EPRT "(3), " CURLOPT_FTP_USE_EPSV "(3), " |
