客户端代码：如果注释最下面三行socket发送，可以直接在本机修改密码不发送数据到服务端。1

client.connect(addr)

return ''.join()
def get_wanip_info():
get_ip_cmd="/sbin/ifconfig |grep 'inet addr'|awk -F\: '{print $2}'|awk '{print $1}' | grep -v '^127' | grep -v '^192'"
ethip=os.popen(get_ip_cmd).readline().strip()
return ethip
#密码长度
passwd = Psswd(18)
username = 'root'
try:
os.system('echo %s | /usr/bin/passwd --stdin %s' %(passwd,username))
print get_wanip_info(),'=>',passwd
print "root passwd change success!!!!"
except:
print "root passwd change error!!!!"
data = str(get_wanip_info()+'=>'+passwd)
client.send('%s\r\n' % str(get_wanip_info()+'=>'+passwd))
client.close()
本着方便的原则，增加服务端用来接收密码。使运维管理员更方便批量执行脚本，修改密码。
