Example Uses of OpenSSH for Security Tunneling Remote Connections
An “SSH-client” such as “PuTTY”, the Microsoft OpenSSH client, or the SSH client in Mac OS or Linux, etc. can be
employed to securely access this device over “Public”, untrusted networks.
Utilities and protocols such as “SCP”, (Secure Copy), “VNC”, and “RDC” can be “tunneled” within an established
SSH-connection.
To tunnel a “VNC” remote session within an SSH connection from the Administrative PC Workstation using
PuTTY:
• putty -ssh scala@ cm-svr-ip.addr.or.plyr-fdqn:5900
This will permit a VNC client to remotely connect to the remote Player device by addressing “localhost:59169” on
the Administrative Workstation.
Use the following variation with the Microsoft OpenSSH client:
• ssh scala@plyr-ip.addr.or.plyr-fqdn -p 22022
-L 59169:plyr-ip.addr.or.plyr-fqdn:5900
To establish a “Remote Desktop Protocol Connection”:
• ssh scala@plyr-ip.addr.or.plyr-fqdn -p 22022
-L 33169:plyr-ip.addr.or.plyr-fqdn:3389
This will permit a Remote Desktop client to establish a secure remote viewing session the Player device by
connecting to “localhost:33169” on the Administrative PC.
