Features: Quickly use SSH to protect your computer network! SSH (Secure Shell) has the characteristics of transparency, strong confidentiality, and trustworthy public key authentication, along with a highly configurable client/server architecture. It is a robust and widely popular network security and privacy protection solution based on the TCP/IP protocol. SSH supports secure remote login and can be used to transfer files securely between computers. Its unique "tunneling" feature can protect other network applications that are not originally secure. And the most important point is that SSH has both a free version and a highly powerful commercial version. This book discusses the technical details of SSH from the perspectives of system administrators and ordinary users, uncovering the mysteries of the SSH manual pages. It covers specific content such as SSH1, SSH2, OpenSSH, and F-SecureSSH versions for Unix, Windows, and Macintosh, including basic concepts, technical insights, and complex applications. The configuration of SSH servers and clients, including service scope configuration and per-account configuration, is also recommended with the strongest security settings. Advanced key management based on agents, key forwarding, and forced commands delve into the forwarding of TCP and X11 applications (i.e., tunneling transmission), and further discuss scenarios involving firewalls and network address translation (NAT) mechanisms. The integration of SSH with other security products such as Kerberos, PGP, and PAM Documentation of some undocumented behaviors in currently popular SSH implementations Troubleshooting of SSH system installation and maintenance: including common issues as well as less common ones. Whether your communication is within a small LAN or across the entire Internet, SSH can securely and efficiently transfer data from "here" to "there." So, discard those insecure .rhosts and hosts.equiv files and upgrade to SSH—your network will become a true space for survival and work.
