Close an SSH Tunnel

See more Socket/SSL/TLS Examples

Demonstrates Socket.SshCloseTunnel, which closes the SSH tunnel opened by SshOpenTunnel and terminates its forwarded channels.

local chilkat = require("chilkat")

local socket = chilkat.Socket.new()

-- Connect to the SSH server and initialize an SSH tunneling session.  Port 22 is conventional but
-- not required.
local success = socket:ssh_open_tunnel("ssh.example.com", 22)
if not success then
    print(socket.last_error_text)
    return
end

-- Authenticate the SSH session before opening forwarded channels.
-- The SSH password should come from a secure source rather than being hard-coded.
local sshPassword = "mySshPassword"
success = socket:ssh_authenticate_pw("sshUser", sshPassword)
if not success then
    print(socket.last_error_text)
    return
end

-- Close the SSH tunnel and terminate its forwarded channels.  This does not affect unrelated SSH
-- objects or connections.
success = socket:ssh_close_tunnel()
if not success then
    print(socket.last_error_text)
    return
end

print("SSH tunnel closed.")
