使用了python中的pexpect模块,在测试代码之前,可输入python进入交互界面,输入help('pexpect'),查询是否本地含有pexpect模块。
如果没有,linux系统输入 easy_install pexpect便可自动安装。
测试代码,连接127.0.0.1
下面是我手动连接127.0.0.1, 发现只有在首次使用ssh连接127.0.0.1时,需要输入yes or no ,而后再次使用ssh ,则不需要再次输入yes
直接输入密码即可。
后续测试代码是二次链接,无需查询是否需要输入yes or no
import pexpect def send_command(child, cmd): child.sendline(cmd) child.expect(PROMT) print child.before def 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 child def main(): host = '127.0.0.1'#测试主机ip或者主机名 user = 'root'#测试账号 password = 'root'#测试密码 child = connect(user, host, password) send_command(child, 'w') if __name__ == '__main__': main()
可以用pxssh模块更简单来完成ssh的连接
from pexpect import pxssh def send_command(s, cmd): s.sendline(cmd) s.prompt() print s.before def 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()
批量连接肉鸡。
from pexpect import pxssh botnet = [] 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.before def 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 output def main(): addclient('root', '127.0.0.1', 'toor') addclient('root', '****', '*****') botnetcommand('pwd') if __name__=='__main__': main()
