使用了python中的pexpect模塊，在測(cè)試代碼之前，可輸入python進(jìn)入交互界面，輸入help('pexpect')，查詢是否本地含有pexpect模塊。

如果沒(méi)有，linux系統(tǒng)輸入 easy_install pexpect便可自動(dòng)安裝。

測(cè)試代碼，連接127.0.0.1

下面是我手動(dòng)連接127.0.0.1， 發(fā)現(xiàn)只有在首次使用ssh連接127.0.0.1時(shí)，需要輸入yes or no ，而后再次使用ssh ,則不需要再次輸入yes

直接輸入密碼即可。

后續(xù)測(cè)試代碼是二次鏈接，無(wú)需查詢是否需要輸入yes or no

import pexpect def send_command(child, cmd):  child.sendline(cmd)  child.expect(PROMT)  print child.beforedef connect(user, host, password):  ssh_newkey = 'Ary you sure you want to continue connecting'  connStr = 'ssh ' + user + '@' + host  child = pexpect.spawn(connStr)  '''  ret = child.expect([pexpect.TIMEOUT, ssh_newkey])  if ret == 0:    print "[-] Error 1"    return  elif ret == 1:    child.sendline('yes')  '''  res = child.expect([pexpect.TIMEOUT, '[P|p]assword:'])  if res == 0:    print "[-] Error 2"    return  elif res == 1:    child.sendline(password)  child.expect(PROMT)  return childdef main():  host = '127.0.0.1'#測(cè)試主機(jī)ip或者主機(jī)名  user = 'root'#測(cè)試賬號(hào)  password = 'root'#測(cè)試密碼  child = connect(user, host, password)  send_command(child, 'w')if __name__ == '__main__':  main()

可以用pxssh模塊更簡(jiǎn)單來(lái)完成ssh的連接

from pexpect import pxsshdef send_command(s, cmd):  s.sendline(cmd)  s.prompt()  print s.beforedef connect(host, user, password):  try:    s = pxssh.pxssh()    s.login(host, user, password)    return s  except:    print "error"    exit(0)def main():  s = connect('127.0.0.1', 'root', '15110506010')  send_command(s, 'whoami')if __name__ == '__main__':  main()

批量連接肉雞。

from pexpect import pxsshbotnet = []class client:	def __init__(self, user, host, password):		self.user=user		self.host=host		self.password=password		self.child=self.connect()	def connect(self):		try:			s = pxssh.pxssh()			s.login(self.host, self.user, self.password)			return s		except Exception, e:			print "Error *" + str(e)	def send_command(self, cmd):		self.child.sendline(cmd)		self.child.prompt()		return self.child.beforedef addclient(user, host, password):	c = client(user, host, password)	botnet.append(c)def botnetcommand(command):	for c in botnet:		output = c.send_command(command)		print "ip: " + str(c.host)		print outputdef main():	addclient('root', '127.0.0.1', 'toor')	addclient('root', '****', '*****')	botnetcommand('pwd')if __name__=='__main__':	main()
