ULTIMATE TOUR GUIDE FOR SECURELY TRANSFERRING FILES 


Sebastopol, CA--"Network security is an increasingly hot topic, and
with around two million SSH users across the globe, the information in
'SSH, The Secure Shell: The Definitive Guide' is pretty timely," says
Daniel J. Barrett, coauthor of this new O'Reilly release (US $39.95).

SSH, the Secure Shell*, is a popular, robust, and powerful
software-based approach to network security. Whenever data is sent by a
computer to the network, SSH automatically encrypts it. When the date
reaches its intended recipient, SSH automatically decrypts it. The
result is "transparent" encryption--users can work normally, unaware
that their communications are safely encrypted on the network. SSH is
an extremely valuable tool that helps users more safely navigate
today's Internet, and helps system administrators secure their networks
or perform remote administration. It supports secure file transfer
between computers, secure remote logins, and a unique "tunneling"
capability that adds encryption to otherwise insecure network
applications. Best of all, SSH is free, with feature-filled commercial
versions available as well.

Because of its flexibility--as well as the existence of multiple
implementations for various operating systems--newcomers to SSH
frequently have lots of questions. "'SSH, The Secure Shell: The
Definitive Guide' is written for a wide, technical audience:
individuals running Linux machines at home, corporate network
administrators with thousands of users, or PC/Mac owners who just want
a secure way to telnet or transfer files between machines," explains
Barrett. "The material starts with simple installation and use of SSH,
but runs all the way to in-depth case studies for highly secure
computing environments."

"SSH: The Secure Shell: The Definitive Guide" covers the Secure Shell
in detail for both system administrators and end users. It demystifies
the SSH man pages and includes thorough coverage of:

- Installing and maintaining SSH systems 
- Configuring SSH servers and clients with recommended settings to
maximize security
- SSH1, SSH2, OpenSSH, and F-Secure SSH for Unix, Windows and Macintosh
products
- Advanced key management using agents, agent forwarding, and forced
commands
- Tunneling of TCP and X11 applications in depth, even in the presence
of firewalls and network address translation (NAT)
- Undocumented behaviors of popular SSH implementations 
- Troubleshooting a wide variety of common and not-so-common problems

So whether you're shipping information on a small LAN or across the
Internet, SSH can ferry your data from here-to-there efficiently and
securely, with O'Reilly's "SSH: The Secure Shell" as the ultimate tour
guide.

*"SSH" is pronounced by spelling it aloud "S-S-H." The name Secure
Shell might seem a little puzzling, as it isn't a shell at all. The
name was coined from the existing rsh utility, an ubiquitous Unix
program that also provides logins, but is not very secure.
