Inovis VAN FTP/SSL (EDI)

Demonstrates how to connect to the Inovis EDI VAN (FTP/SSL). 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()

ftp.hostname = "ftpssl.gateway.inovisworks.net"
ftp.username = "myLogin"
ftp.password = "myPassword"

-- The Inovis EDI VAN requires Passive connections:
ftp.passive = true

-- Note: The Inovis documentation mentions an outbound
-- high port range of 40000-49999.  In passive mode, the
-- FTP server chooses the port number for the data
-- connection.  The Inovis server will choose a port number
-- in the range 40000-49999.  To establish the data connection,
-- your firewall must allow outgoing connections in that port
-- range.

-- This tells Chilkat FTP2 to establish
-- an AUTH TLS secure channel after connecting
-- on the standard FTP port 21.
ftp.auth_tls = true

-- You'll probably need this property set to true if you're
-- behind a NAT router or firewall.
ftp.passive_use_host_addr = true

-- The Ssl property is for establishing an implicit SSL connection
-- on port 990.  Do not set it to true.  The Inovis VAN
-- uses explicit encryption (SSL/TLS).
ftp.ssl = false

-- The Chilkat FTP component automatically sends a "FEAT";
-- command after connecting.  This allows the component
-- to better know the FTP server's capabilities.
-- The Invois server doesn't recognize the FEAT command,
-- so disable it:
ftp.auto_feat = false

-- Connect, convert to TLS, 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("Connection to Inovis EDI VAN OK!")

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

success = ftp:disconnect()
