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.

require 'chilkat'

success = false

socket = Chilkat::CkSocket.new()

#  Connect to the SSH server and initialize an SSH tunneling session.  Port 22 is conventional but
#  not required.
success = socket.SshOpenTunnel("ssh.example.com",22)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

#  Authenticate the SSH session before opening forwarded channels.
#  The SSH password should come from a secure source rather than being hard-coded.
sshPassword = "mySshPassword"
success = socket.SshAuthenticatePw("sshUser",sshPassword)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

#  Close the SSH tunnel and terminate its forwarded channels.  This does not affect unrelated SSH
#  objects or connections.
success = socket.SshCloseTunnel()
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

print "SSH tunnel closed." + "\n";
