Are you serious about network security? Then check out SSH, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, SSH eliminates several of them very effectively.Everything you want to know about SSH is in our second edition of SSH, The Secure Shell: The Definitive Guide. This updated book thoroughly covers the latest SSH-2 protocol for system administrators and end users interested in using this increasingly popular TCP/IP-based solution.How does it work? Whenever data is sent to the network, SSH automatically encrypts it. When data reaches its intended recipient, SSH decrypts it. The result is "transparent" encryption-users can work normally, unaware that their communications are already encrypted. SSH supports secure file transfer between computers, secure remote logins, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. With SSH, users can freely navigate the Internet, and system administrators can secure their networks or perform remote administration.Written for a wide, technical audience, SSH, The Secure Shell: The Definitive Guide covers several implementations of SSH for different operating systems and computing environments. Whether you're an individual running Linux machines at home, a corporate network administrator with thousands of users, or a PC/Mac owner who just wants a secure way to telnet or transfer files between machines, our indispensable guide has you covered. It starts with simple installation and use of SSH, and works its way to in-depth case studies on large, sensitive computer networks.No matter where or how you're shipping information, SSH, The Secure Shell: The Definitive Guide will show you how to do it securely.

你对网络安全很认真吗？那就看看SSH，即安全壳，它为你的网络连接提供基于密钥的认证和透明的加密。它是可靠的，强大的，而且相当容易使用，免费的和商业的实现都广泛适用于大多数操作系统。虽然它不能解决所有的隐私和安全问题，但SSH可以非常有效地消除其中的几个问题。你想知道的关于SSH的一切都在我们的SSH第二版《安全壳》中。你想知道的关于SSH的一切都在我们的第二版《安全外壳：权威指南》中。这本更新的书彻底涵盖了最新的SSH-2协议，供系统管理员和对使用这种日益流行的基于TCP/IP的解决方案感兴趣的最终用户使用。它是如何工作的？每当数据被发送到网络时，SSH会自动对其进行加密。当数据到达预定的接收者时，SSH会对其进行解密。其结果是 "透明 "的加密--用户可以正常工作，不知道他们的通信已经被加密了。SSH支持计算机之间的安全文件传输，安全的远程登录，以及一种独特的 "隧道 "功能，为其他不安全的网络应用增加了加密功能。有了SSH，用户可以自由地浏览互联网，而系统管理员可以保护他们的网络或进行远程管理。为广大技术读者而写，《SSH，安全外壳：权威指南》涵盖了不同操作系统和计算环境下的SSH的几种实现方式。无论你是在家里运行Linux机器的个人，还是拥有成千上万用户的企业网络管理员，或者只是想用安全的方式在机器之间远程登录或传输文件的PC/Mac拥有者，我们不可或缺的指南都会涵盖你。它从SSH的简单安装和使用开始，一直到大型敏感计算机网络的深入案例研究。无论你在哪里或以何种方式运送信息，《SSH，安全外壳：权威指南》都会告诉你如何安全地进行运送。
