SFTP Simplified Upload

See more SFTP Examples

Demonstrates how to upload a file to an SSH server in the simplest way -- by calling UploadFileByName and passing remote and local filepaths. Lua

local chilkat = require("chilkat")

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

local sftp = chilkat.SFtp.new()

-- Set some timeouts, in milliseconds:
sftp.connect_timeout_ms = 15000
sftp.idle_timeout_ms = 15000

-- Connect to the SSH server.
-- The standard SSH port = 22
-- The hostname may be a hostname or IP address.
local hostname = "sftp.example.com"
local port = 22
local success = sftp:connect(hostname, port)
if not success then
    print(sftp.last_error_text)
    return
end

-- Authenticate with the SSH server.  Chilkat SFTP supports
-- both password-based authenication as well as public-key
-- authentication.  This example uses password authenication.
success = sftp:authenticate_pw("myLogin", "myPassword")
if not success then
    print(sftp.last_error_text)
    return
end

-- After authenticating, the SFTP subsystem must be initialized:
success = sftp:initialize_sftp()
if not success then
    print(sftp.last_error_text)
    return
end

-- Upload from the local file to the SSH server.
-- Important -- the remote filepath is the 1st argument,
-- the local filepath is the 2nd argument;
local remoteFilePath = "hamlet.xml"
local localFilePath = "c:/temp/hamlet.xml"

success = sftp:upload_file_by_name(remoteFilePath, localFilePath)
if not success then
    print(sftp.last_error_text)
    return
end

print("Success.")
