Howdy,

I've had an SSH Tunnel Script working for a long time now as a 32-bit Chilkat app and it works well, but once I registered the 64-bit DLL for 9.5.0.58, it started throwing exceptions like this... (p.s. this looks like a bug in 9.5.0.58 x86 and x64)

C:scripts>cscript sshtunnel.vbs 192.168.0.133-rdp 192.168.0.107-rdp
Microsoft (R) Windows Script Host Version 5.812

--->Tunnel will listen indefinitely <--- ---> Press Ctrl-C to shutdown the tunnel listener<---

192.168.0.133-rdp Found: 192.168.0.133-rdp 192.168.0.133:3389 on 22 Connecting through: xxx.xxx.xxx.xxx:22 Tested Tunnel parameters! ERROR WHILE TRYING TO START ACCEPTING: ChilkatLog: BeginAccepting: DllDate: Jun 13 2016 ChilkatVersion: 9.5.0.58 UnlockPrefix: CHANGEDFORPRIVACY Architecture: Little Endian; 64-bit Language: ActiveX / x64 VerboseLogging: 0 listenPort: 3333 dynamicPortForwarding: 0 StaticPortForwarding: destPort: 3389 destHostname: 192.168.0.107 --StaticPortForwarding Not yet connected to the SSH tunnel. Failed. --BeginAccepting --ChilkatLog

And then unregistering the x64 DLL and reregistering the x86 DLL worked like a charm (script worked as expected)... although the working 32-bit DLL is version 9.5.0.48.

P.S. trying to make 9.5.0.58 32-bit DLL work, fails at same place.

For the time being, I'll just keep using the 32-bit 9.5.0.48 as I don't know where to download the x64 version from (only the current one [9.5.0.58] seems available). I am guessing this is a bug introduced after ".48".

Please let me know what you find, Steven

Here's my code... which was adapted from your samples

Function chillkat_establish_ssh_tunnel (sshTunnel,desthost,destport,throughhost,throughport,throughuser,throughpass,locallistenport)
  On Error Resume Next

'  The DestHostname may be the domain name or
  '  IP address (in dotted decimal notation) of the database
  '  server.

''we need to test that our tunnel will work first...

Set ssh = CreateObject("Chilkat_9_5_0.Ssh")
  if Err.Number <> 0 Then
    WScript.Echo "  Error creating Object: " & Err.Description
      chillkat_establish_ssh_tunnel = 0
      Exit Function
  End If
  '  Any string automatically begins a fully-functional 30-day trial.
  success = ssh.UnlockComponent(ssh_unlock_code)
  If (success <> 1) Then
      WScript.Echo "error unlocking SSH with unlock code!"
      chillkat_establish_ssh_tunnel = 0
      Exit Function
  End If
  WScript.Echo "Connecting through: " & throughhost & ":" & throughport
  success = ssh.Connect(throughhost,throughport)
  If (success <> 1) Then
      WScript.Echo "  Error connecting to SSH through host in test: " & ssh.LastErrorText
      chillkat_establish_ssh_tunnel = 0
      Exit Function
  End If

'  Wait a max of 5 seconds when reading responses..
  ssh.IdleTimeoutMs = 5000

success = ssh.AuthenticatePw(throughuser,throughpass)
  If (success <> 1) Then
      WScript.Echo "  Error authenticating to SSH for ""through host"" in test: " & ssh.LastErrorText
      chillkat_establish_ssh_tunnel = 0
      Exit Function
  End If

ssh.Disconnect
  Err.Clear
  WScript.Echo "    Tested Tunnel parameters!"
  sshTunnel.DestHostname = desthost
  sshTunnel.DestPort = destport

sshTunnel.SshHostname = throughhost
  sshTunnel.SshPort = throughport
  sshTunnel.SshLogin = throughuser
  sshTunnel.SshPassword = throughpass

success = sshTunnel.BeginAccepting(locallistenport)
  If (success <> 1) Then
      WScript.Echo "  ERROR WHILE TRYING TO START ACCEPTING: "
      WScript.Echo sshTunnel.LastErrorText
      chillkat_establish_ssh_tunnel = 0
      Exit Function
  End If

chillkat_establish_ssh_tunnel = 1
End Function

Sorry, forgot to add the environment info..

Windows 10 Pro x64, although I am not sure that it matters.

Thanks, Steven

With the flaw you are suggesting, the tunneling wouldn't work using 9.5.0.48.

While I do use SSH at the start (to test the credentials), you should notice that I switch over to the sshTunnel object which is a fully qualified 9.50 sshTunnel object. I'll be happy to give you the script in it's entirety, if you wish.. I just didn't want to overload the forum with the whole thing...

Here's the appropriate part of the function that creates the ssh object then closes it.. and moves on to the ssh tunnel object.

ssh.Disconnect

Err.Clear

WScript.Echo " Tested Tunnel parameters!"

sshTunnel.DestHostname = desthost

sshTunnel.DestPort = destport

sshTunnel.SshHostname = throughhost

sshTunnel.SshPort = throughport

sshTunnel.SshLogin = throughuser

sshTunnel.SshPassword = throughpass

success = sshTunnel.BeginAccepting(locallistenport)

Again.. This script totally works in 9.5.0.48... Did you change the functionality to require a Connect?

If you are suggesting I now NEED to use the connect function, I can.

HMMM... Score one for not looking at the newer release documentation. :(

https://www.chilkatsoft.com/refdoc/xChilkatSshTunnelRef.html

Apologies for thinking there was a bug..

“Connect was Introduced in 9.5.0.50”

I'll just quietly slink back to my corner of the Internet, and fix my code. :)

You're connecting using an Ssh object, which is not associated with the SshTunnel object in any way -- and therefore the connection is meaningless.

See this example: https://www.example-code.com/vbscript/sshTunnel_database.asp

The "Connect" call is on the SshTunnel object.
