SSH or Secure Shell is a third party add-on for Windows and Linux which directly replaces the standard hyperterminal service.
The problem with hyperterminal and Telnet is that they transmit passwords in clear text across the network - not ideal security, I think you will agree.
SSH is configurable, just like hyperterminal and is currently enjoying a lot of use within the Linux community, thanks to its strong password encryption.
Google and grab the SSH RPM install, ssh-3.0.1-1.i386.rpm or its updated equivalent (SSH for Linux).
Installing SSH under Red Hat Linux
Copy the RPM installation package to the Linux box. Change the working directory to the directory where you have copied the installation package and issue the following command using the filename above as an exampe:
rpm -ihv ssh-3.0.1-1.i386.rpm
The command varies a bit according to the software and RPM release version. If you have previous SSH Secure Shell RPMs installed, issue the following command with root privileges:
rpm -Uhv ssh-3.0.1-1.i386.rpm
After issuing the command, the software will be installed. You might be asked to accept the License Agreement if you have not done so previously, or if the License has changedfrom a previous version.
SSH should now be ready to use. If you already had the Secure Shell daemon running, restart it or reboot the computer. Kill and/or remove any telnet service.
