SCP Upload to a Specific Remote Directory

See more SCP Examples

Demonstrates how to upload a file using the SCP protocol (Secure Copy Protocol over SSH). The file is uploaded to a specific remote directory. It can be either a path relative to the HOME directory of the SSH user account, or an absolute path on the remote filesystem. Obviously, in both cases the SSH user account must have permission to create or overwrite a file in the specified directory. Lua

local chilkat = require("chilkat")

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

local ssh = chilkat.Ssh.new()

-- Connect to an SSH server:

-- Hostname may be an IP address or hostname:
local hostname = "www.some-ssh-server.com"
local port = 22

local success = ssh:connect(hostname, port)
if not success then
    print(ssh.last_error_text)
    return
end

-- Wait a max of 5 seconds when reading responses..
ssh.idle_timeout_ms = 5000

-- Authenticate using login/password:
success = ssh:authenticate_pw("myLogin", "myPassword")
if not success then
    print(ssh.last_error_text)
    return
end

-- Once the SSH object is connected and authenticated, we use it
-- as the underlying transport in our SCP object.
local scp = chilkat.Scp.new()

success = scp:use_ssh(ssh)
if not success then
    print(scp.last_error_text)
    return
end

-- This uploads a file to the "uploads/text" directory relative to the HOME
-- directory of the SSH user account.  For example, if the HOME directory is /home/chilkat,
-- then this uploads to /home/chilkat/uploads/text/test.txt
-- Note: The remote target directory must already exist on the SSH server.
local remotePath = "uploads/text/test.txt"
local localPath = "/home/bob/test.txt"
success = scp:upload_file(localPath, remotePath)
if not success then
    print(scp.last_error_text)
    return
end

-- This upload fully specifies the absolute remote path.
remotePath = "/home/chilkat/junk/abc/hamlet.xml"
localPath = "/home/bob/hamlet.xml"
success = scp:upload_file(localPath, remotePath)
if not success then
    print(scp.last_error_text)
    return
end

print("SCP upload file success.")

-- Disconnect
