FTPS / Implicit SSL

See more FTP Examples

Demonstrates how to connect using implicit SSL on port 990. The FTP component connects using SSL on port 990, which is the de-facto standard FTP SSL port. Not all FTP servers support implicit SSL. An alternative is to use AUTH SSL (also called AUTH TLS). Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local ftp = chilkat.Ftp2.new()

-- If this example does not work, try using passive mode
-- by setting this to true.
ftp.passive = false
ftp.hostname = "ftp.something.com"
ftp.username = "test"
ftp.password = "test"
ftp.port = 990

-- We don't want AUTH SSL:
ftp.auth_tls = false

-- We want Implicit SSL:
ftp.ssl = true

-- Connect and login to the FTP server.
local success = ftp:connect()
if not success then
    print(ftp.last_error_text)
    return
else
    -- LastErrorText contains information even when
    -- successful. This allows you to visually verify
    -- that the secure connection actually occurred.
    print(ftp.last_error_text)
end

print("FTPS Channel Established!")

-- Do whatever you're doing to do ...
-- upload files, download files, etc...

success = ftp:disconnect()
