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.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'#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 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()

批量连接肉鸡。

from pexpect import pxsshbotnet = []class client:def __init__(self, user, host, password):self.user=userself.host=hostself.password=passwordself.child=self.connect()def connect(self):try:s = pxssh.pxssh()s.login(self.host, self.user, self.password)return sexcept 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()
