On the windows box, use putty to create a ssh tunnel to your Linux box. This way nothing is transferred unencrypted over the network.

Where I am constrained to Linux Jump servers. That now only have SSH. The Telnet is GONE on the jump servers. The closed source programs once connected (formerly via telnet) to the jump servers then know who to issue the commands to ssh into the remote targets. I need a way to translate Telnet to SSH on the jump servers. The netcat on the jump servers do not have the –e option, so I cannot run nc in telnet mode into /bin/bash. I have found mkfifo pipe_name_inmkfifo pipe_name_outnc -l 5555 < pipe_name_out | /bin/bash > pipe_name_in which kind of works. However, the Standard Error does not go down the pipe. So I don’t get any echo or prompts, only the response. nc -l 5555 < pipe_name_out | /bin/bash 2> pipe_name_indoes get the some of the prompts but then no responses. nc -l 5555 < pipe_name_out | /bin/bash 2>&1 pipe_name_infails to allow connections. Any suggestions or solutions? Michael P.
