SSH Secure Shell, Version 3
Secure Shell secures connections over the Internet by encrypting passwords
and other data. Once launched, it transparently provides strong authentication
and secure communications over insecure networks. ALL NU campus
networks should be considered insecure.
The SSH Secure Shell Version 3 is a secure replacement for programs
that login remotely to other hosts -- programs such as telnet,
ftp, rlogin, rsh and rcp.
If you are using any of the above programs, you should use ssh
instead.
Northwestern University has a Non-Commercial Use License Agreement
with SSH Communications Security Corporation for the campus-wide distribution
of SSH Secure Shell to students, faculty and staff.
See the SSH Communications Security SSH
Security Products web page for descriptions of their products. The SSH
Communications Security FAQ maybe found at http://www.ssh.com/support/faq/.
For more general information about SSH, see The
Secure Shell (SSH) Frequently Asked Questions.
To make a secure connection, SSH must be installed on both the
machine your connection originates from and the machine you are connecting
to.
Most typically, you'll want to install the Windows
Client on your PC so you can securely connect to a UNIX server.
Provided Platforms
Our free SSH license covers two platforms:
- Windows - SSH 3.2.9 client binary for Microsoft Windows 95,
98, NT, 2000 , ME, XP and Vista. Use the client to make a secure
connection from your desktop computer to another host on the network
that is running an SSH server.
- UNIX - SSH 3.2.9.1 source code for non-commercial version: AIX, Solaris,
HPUX, Linux, BSD, Digital UNIX.
- Classic Macintosh - Get MacSSH
under separate license. See http://www.math.ohio-state.edu/support/ssh/mac/macssh/
for configuration tips.
- Windows 2000/XP - WinSSHD
SSH server for Windows provides secure remote access to your
Windows machine. You will have to pay for this product.
- Windows 2000/XP - OpenSSH server and client using the Cygwin
UNIX environment for Windows. Start by installing the
Cygwin DLL and then add the OpenSSH package for the Cygwin environment.
See http://www.openssh.com/ to
learn more about the OpenSSH connectivity tools.
- Windows 2000/XP - OpenSSH
for Windows is a free package that installs a minimal OpenSSH server
and client in the Cygwin package without needing the full Cygwin installation.
This package is simpler to install, and contains extended feature support
beyond that linked to in the bullet above.
The Windows SSH 3 Client Binary
- Review the License agreement for SSH Secure Shell for Workstations,
and make sure that you meet the terms and restrictions of the NON-COMMERCIAL
USE LICENSE.
- Download the
Windows SSH installer and save the file SSHSecureShellClient-3.2.9.exe
in your Documents folder. You may have to right-click
that link and choose "Save Link As" or "Save Target As.." to properly
download the file.
- Run the SSH installer by double-clicking the file SSHSecureShellClient-3.2.9.exe.
An existing SSH installation should be detected and automatically updated.
- Test the newly installed program by double clicking on the Secure
Shell Client application in the Start/Programs/SSH Secure Shell
menu.
- You may now delete the temporary installer file.
Multiple Sessions. This program prevents you from opening
sessions to different hosts at the same time. The workaround is to launch
a new copy of the program for each host you want to connect to. Multiple
windows (or sessions) to a single host work nicely.
