Route Socket Connections through an SSH Object

See more Socket/SSL/TLS Examples

Demonstrates Socket.UseSsh, which configures a socket to route subsequent Connect calls through an already connected and authenticated Ssh object using SSH port forwarding.

local chilkat = require("chilkat")

local ssh = chilkat.Ssh.new()

-- Connect and authenticate a standalone SSH object.
local success = ssh:connect("ssh.example.com", 22)
if not success then
    print(ssh.last_error_text)
    return
end

-- The SSH password should come from a secure source rather than being hard-coded.
local sshPassword = "mySshPassword"
success = ssh:authenticate_pw("sshUser", sshPassword)
if not success then
    print(ssh.last_error_text)
    return
end

local socket = chilkat.Socket.new()

-- Route subsequent Connect calls through the already connected and authenticated SSH object.  The
-- destination is reached by SSH port forwarding rather than by a direct TCP connection.
success = socket:use_ssh(ssh)
if not success then
    print(socket.last_error_text)
    return
end

-- Connect to the destination through the SSH tunnel.
local bTls = false
local maxWaitMs = 5000
success = socket:connect("db.internal", 5432, bTls, maxWaitMs)
if not success then
    print(socket.last_error_text)
    return
end

print("Connected to the destination through the SSH tunnel.")
