On Linux & Solaris 10, the following code works but if it is Solaris 11, it throws the following error message paramiko.ssh_exception.AuthenticationException: Authentication failed.. The credentials/authentication details are correct. The host, username and password are all correct but for some reason it complains about Authentication failure. I know that Solaris 11 has much more beefed up security. Is there any thing else I need to add to my code to get this to work? (more details below):
def setup_remote_gateway_client_connection(self, gateway_host, gateway_username, gateway_password, client_host, client_username, client_password, gateway_port=22, client_port=22):
self.gateway_host=paramiko.SSHClient()
self.gateway_host.set_missing_host_key_policy(paramiko.AutoAddPolicy())
self.gateway_host.connect(gateway_host, username=gateway_username, password=gateway_password )
gateway_transport = self.gateway_host.get_transport()
src_addr = (gateway_host, gateway_port)
dest_addr = (client_host, client_port)
gateway_channel = gateway_transport.open_channel("direct-tcpip", dest_addr, src_addr)
client_host=paramiko.SSHClient()
client_host.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client_host.connect(client_host, username=client_username, password=client_password, sock=gateway_channel)
stdin, stdout, stderr = client_host.exec_command('ls -la')
for line in stdout.read().split(b'\n'):
print(str(line))
stdin, stdout, stderr = client_host.exec_command('hostname')
for line in stdout.read().split(b'\n'):
print(str(line))
client_host.close()
self.gateway_host.close()
Upon execution, I get the following:
