(AutoIt) SSH Tunnel with Dynamic Port Forwarding

Demonstrates how to start a background thread that runs a portable SSH tunnel w/ dynamic port forwarding that the foreground thread can use for establishing connections through an SSH tunnel.

; Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
; by calling UnlockBundle.  It requires a Bundle unlock code.
$oChilkatGlob = ObjCreate("Chilkat.Global")
Local $bSuccess = $oChilkatGlob.UnlockBundle("Anything for 30-day trial.")
If ($bSuccess <> True) Then
    ConsoleWrite($oChilkatGlob.LastErrorText & @CRLF)
    Exit
EndIf

; This example requires Chilkat version 9.5.0.50 or greater.
$oTunnel = ObjCreate("Chilkat.SshTunnel")

Local $sshHostname = "sftp.example.com"
Local $iSshPort = 22

; Connect to an SSH server and establish the SSH tunnel:
$bSuccess = $oTunnel.Connect($sshHostname,$iSshPort)
If ($bSuccess <> True) Then
    ConsoleWrite($oTunnel.LastErrorText & @CRLF)
    Exit
EndIf

; Authenticate with the SSH server via a login/password
; or with a public key.  
; This example demonstrates SSH password authentication.
$bSuccess = $oTunnel.AuthenticatePw("mySshLogin","mySshPassword")
If ($bSuccess <> True) Then
    ConsoleWrite($oTunnel.LastErrorText & @CRLF)
    Exit
EndIf

; Indicate that the background SSH tunnel thread will behave as a SOCKS proxy server
; with dynamic port forwarding:
$oTunnel.DynamicPortForwarding = True

; We may optionally require that connecting clients authenticate with our SOCKS proxy server.
; To do this, set an inbound username/password.  Any connecting clients would be required to 
; use SOCKS5 with the correct username/password.
; If no inbound username/password is set, then our SOCKS proxy server will accept both
; SOCKS4 and SOCKS5 unauthenticated connections.

$oTunnel.InboundSocksUsername = "chilkat123"
$oTunnel.InboundSocksPassword = "password123"

; Start the listen/accept thread to begin accepting SOCKS proxy client connections.
; Listen on port 1080.
$bSuccess = $oTunnel.BeginAccepting(1080)
If ($bSuccess <> True) Then
    ConsoleWrite($oTunnel.LastErrorText & @CRLF)
    Exit
EndIf

; Now that a background thread is running a SOCKS proxy server that forwards connections
; through an SSH tunnel, it is possible to use any Chilkat implemented protocol that is SOCKS capable,
; such as HTTP, POP3, SMTP, IMAP, FTP, etc.  The protocol may use SSL/TLS because the SSL/TLS
; will be passed through the SSH tunnel to the end-destination.  Also, any number of simultaneous
; connections may be routed through the SSH tunnel.

; For this example, let's do a simple HTTPS request:
Local $sUrl = "https://www.ethereum.org/"

$oHttp = ObjCreate("Chilkat.Http")

; Indicate that the HTTP object is to use our portable SOCKS proxy/SSH tunnel running in our background thread.
$oHttp.SocksHostname = "localhost"
$oHttp.SocksPort = 1080
$oHttp.SocksVersion = 5
$oHttp.SocksUsername = "chilkat123"
$oHttp.SocksPassword = "password123"

$oHttp.SendCookies = True
$oHttp.SaveCookies = True
$oHttp.CookieDir = "memory"

; Do the HTTPS page fetch (through the SSH tunnel)
Local $sHtml = $oHttp.QuickGetStr($sUrl)
If ($oHttp.LastMethodSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; Stop the background listen/accept thread:
Local $bWaitForThreadExit = True
$bSuccess = $oTunnel.StopAccepting($bWaitForThreadExit)
If ($bSuccess <> True) Then
    ConsoleWrite($oTunnel.LastErrorText & @CRLF)
    Exit
EndIf

; Close the SSH tunnel (would also kick any remaining connected clients).
$bSuccess = $oTunnel.CloseTunnel($bWaitForThreadExit)
If ($bSuccess <> True) Then
    ConsoleWrite($oTunnel.LastErrorText & @CRLF)
    Exit
EndIf
