by Van Dyke Technologies, is a commercial SSH client for Microsoft
Windows 9x, NT, and 2000. It is structured as a terminal program; in
fact, it is based on the terminal program CRT, another Van Dyke
product. As a result, SecureCRT's terminal capabilities are
quite configurable. It includes emulation of several terminal types,
logins via Telnet as well as SSH, a scripting language, a keymap
editor, SOCKS firewall support, chat features, and much more. We will
focus only on its SSH capabilities, however.
SecureCRT supports both SSH-1 and SSH-2 in a single program. Other
important features include port forwarding, X11 packet forwarding,
and support for multiple SSH identities. It doesn't include an
agent. Secure file copy is accomplished not by an
scp-type program, but by
ZModem, the old protocol
for uploading and downloading files. (The remote machine must have
ZModem installed.) If ZModem is used while you're logged in via
SSH, these file transfers are secure.
We've organized this chapter to mirror the first part of the
book covering Unix SSH implementations. When appropriate, we refer
you to the earlier material for more detailed information.
Our discussion of SecureCRT is based on Version 3.1.2, dated
15.1. Obtaining and Installing
may be purchased and downloaded from Van Dyke Technologies:
A free evaluation version is available, expiring 30 days after
installation, so you can try before you buy. Installation is
straightforward and glitch-free. The software is distributed as a
single .exe file; simply run it to install the
program. You will need a serial number and license key to unpack the
archive, and these are provided by Van Dyke to each registered user.
Follow the onscreen instructions, installing the software in any
folder you like. We accepted the default choices.
