You don't need to use key to authenticate using username and password,
indeed. And you don't. Your first email was almost correct, you just
needed to add event.wait() after t.auth_password. It worked here after
doing that change. You can check out my version:
import sys
import socket
import paramiko
import threading
if len(sys.argv) != 4:
print "%s hostname user password" % sys.argv[0]
sys.exit(1)
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((sys.argv[1], 22))
t = paramiko.Transport(sock)
event = threading.Event()
t.start_client(event)
event.wait()
if not t.is_active():
print 'SSH negotiation failed.'
sys.exit(1)
else:
print "SSH negotiation sucessful"
event.clear()
t.auth_password(username=sys.argv[2], password=sys.argv[3], event=event)
event.wait()
if not t.is_authenticated():
print "Authentication failed."
else:
print "Authenticated!"
t.close()
