Table of Products (SSH, The Secure Shell: The Definitive Guide)

13.3. Table of Products

Unfortunately we can't cover every SSH implementation, but here are summaries to aid your explorations. The following tables list the major features of every SSH implementation we have encountered, sorted by platform, excluding the Unix products discussed in the previous part of the book (SSH1, SSH2, OpenSSH, F-Secure SSH). The meanings of the entries are described in this first table:

Feature	Meaning
Name	The product name. If followed by "(recommended)," we have evaluated the program and recommend its use. If a product isn't listed as recommended, it might still be good, but we didn't evaluate it thoroughly.
Platform	Does it run on Windows, Macintosh, Unix, etc.? We don't list specific Windows variants (NT, 98, 2000, etc.) because we couldn't test them all. Contact the vendor for details.
Version	What is the most recent version number at press time?
License or distribution	How may this program be distributed? We provide only a summary of the licensing information; see the product documentation for full information.
Protocol	Does it implement SSH-1, SSH-2, or both?
Remote logins	Can the product open a login shell to a remote machine? We write either "ssh" to denote a command-line interface à la SSH1 or SSH2, or "terminal program" to denote a graphical interface
Remote commands	Can it invoke individual commands on a remote SSH server machine, in the manner of the `ssh` client (i.e., providing a command string as a final argument)?
File transfer	What program, if any, transmits files securely between machines?
Server	Does it include an SSH server?
Authentication	What forms of authentication are supported?
Key generation	Can it generate private/public key pairs?
Agent	Does it include an SSH agent?
Forwarding	Does it support port forwarding, X forwarding, both, or neither?
Notes	General information and supporting details.
Contact	URL to locate the software.

The remainder of this section is an extended table summarizing the many SSH implementations.

Notes
This recent product could bring SSH2 to the masses; the scp2 client is particularly nice, emulating the Windows Explorer, permitting remote files to be dragged securely between machines; extensive documentation; SSH2 server is a separate product
A solid performer; our favorite of the commercial Windows clients
A secure, graphical FTP client for SSH2
Graphical terminal emulator with SSH support
