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.

Dim success As Boolean = False

Dim ssh As ChilkatSsh
ssh.Initialize("ssh")

'  Connect and authenticate a standalone SSH object.
success = ssh.Connect("ssh.example.com", 22)
If success = False Then
    Log(ssh.LastErrorText)
    Return
End If


'  The SSH password should come from a secure source rather than being hard-coded.
Dim sshPassword As String = "mySshPassword"
success = ssh.AuthenticatePw("sshUser", sshPassword)
If success = False Then
    Log(ssh.LastErrorText)
    Return
End If


Dim socket As ChilkatSocket
socket.Initialize("socket")

'  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.UseSsh(ssh)
If success = False Then
    Log(socket.LastErrorText)
    Return
End If


'  Connect to the destination through the SSH tunnel.
Dim bTls As Boolean = False
Dim maxWaitMs As Int = 5000
success = socket.Connect("db.internal", 5432, bTls, maxWaitMs)
If success = False Then
    Log(socket.LastErrorText)
    Return
End If

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