Hi
Within our internal network, we have a test system that allows several client machines to log in to a Server using telnet, port 23 - The clients have a terminal emulation application installed to allow this, but it doesn?t support SSH ? I would like to know if there is an application that has the potential to convert telnet to SSH via tunnelling ? It?s imperative we keep the existing emulation software.
Cheers

It's relatively easy to set up an SSH tunnel. When properly installed, the use should be transparent.

The important thing is that the SSH layer makes the login a two-step process - first establishing the SSH connection and tunnels, then connecting to telnet.

Set up ipsec on the test system so that port 23 is only accessible to 127.0.0.1, and may not be connected by outside machines. Load an SSH host and configure a tunnel on port 23 to 127.0.0.1 (depends on software where the configuration is done)

Then set up the SSH client on the client machines, with the tunnel on port 23, and establish a connection.

Your client machines will log in via telnet to 127.0.0.1 - themselves. The SSH tunnel will connect them to the test system, securely.
