小心重庆美联英语的注册金骗局

上周末去重庆观音桥的美联英语咨询情况,结果被里面的要求交什么注册金,300元(因为我只带了300元)。但我第二天回来在Google、百度上搜索他们情况后发现并不是我理想中的那样。当我提到退款时,就说不能退的啦。我立马打12315电话。我说明情况之后,重庆12315的工作人员,只问了一句“他是培训机构吗?”。我说“是”。“那你打教委的电话”,“请问教委的电话是多少呢?”。“你自己打114查询啊”。

……

天啊,这也叫便民?难道真把我们当便民了?当然我没有打教委的电话,说实话,我是第一次打12315在我心中一直是能够为消费者办事的电话,结果呢?我已经对这些所谓的“服务”失去信心了。以后还是小心点算了吧。

让我们来看看一些有趣的东西吧:

NFS quick howto for centos 5

NFS quick howto for centos 5

To use nfs successfully, you have to configure the server and the client. In this example, the client is 192.168.0.3 and the server is 192.168.0.1. The folder to be shared is /home/sharing, and to be mounted to /mnt on the client

On the server

  1. Make directory that you want to use.
    • # mkdir /home/sharing
  2. Edit /etc/exports, insert the client machine’s ip
    • # vi /etc/exports
    • Add this line:
    • /home/sharing 192.168.0.3/255.255.255.255(rw,sync)
  3. Save
  4. Edit /etc/hosts.allow
    • # vi /etc/hosts.allow
    • Add this line:
    • portmap: 192.168.0.0/255.255.255.0
  5. Save
  6. Start nfs and portmap
    • # /etc/init.d /nfs start
    • # /etc/init.d/portmap start
On the client
  1. Start portmap
    • # /etc/init.d/portmap start
  2. Mount the nfs folder
    • # mount 192.168.0.1:/home/sharing /mnt
  3. Check /var/log/messages for any error that might occur
    • # tailf /var/log/messages
  4. Use mount to check if the folder is mounted properly
    • # mount 
    • This should be the output:
    • 192.168.0.1:/home/sharing on /mnt type nfs (rw,addr=192.168.0.1)
  5. Edit /etc/fstab to mount the shared folder on boot
    • # vi /etc/fstab
    • Add this line
    • 192.168.0.1:/mnt/sdb1/backup /mnt nfs rw,hard,intr 0 0
  6. Save
You can use 'man exports' to see the options available for /etc/exports
