每次我SSH到我的AWS Ubuntu服务器，我看到一个系统信息消息，显示负载，内存使用情况和可用的安装包，如下所示：
Welcome to Ubuntu 12.04.3 LTS (GNU/Linux 3.2.0-51-virtual x86_64) * Documentation: https://help.ubuntu.com/ System information as of Sun Nov 10 18:06:43 EST 2013 System load: 0.08 Processes: 127 Usage of /: 4.9% of 98.43GB Users logged in: 1 Memory usage: 69% IP address for eth0: 10.236.136.233 Swap usage: 100% Graph this data and manage this system at https://landscape.canonical.com/ 13 packages can be updated. 0 updates are security updates.

这个login消息是由Ubuntu的landscape包创build的。 我个人认为，他们很烦人，所以configuration好了可以将这些软件包加载并设置一个空白的login信息。
要做到这一点：
$ apt-get remove landscape-client landscape-common $ rm -f /etc/motd && touch /etc/motd
这将创build一个空白的/etc/motd 。 要设置自定义login消息，请根据需要编辑该文件。
在我的情况下，我必须清除/etc/update-motd.d/51-cloudguest ，内容如下：
#!/bin/sh # # This file is written by the Ubuntu image build process, it is not # managed by a package. If you want to avoid seeing this advertisement, # then you can safely remove the file. echo "" echo " Get cloud support with Ubuntu Advantage Cloud Guest:" echo " http://www.ubuntu.com/business/services/cloud" echo "" echo " Use Juju to deploy your cloud instances and workloads:" echo " https://juju.ubuntu.com/#cloud-saucy"
