Establish a cascaded Telnet session

Learn how to establish another Telnet session while in a Telnet session. After you establish a cascaded session, you can move between the different systems.

You can start a Telnet session while currently in a Telnet session. The home system is the first client system that you use. The end system is the last Telnet server system that you access. The system that you pass through to get from the home system to the end system is an intermediate system.

Starting a cascaded session

To start your cascaded session, sign on to the home system, then follow the steps to establish a client session. Repeat the steps for each system you want to connect to.

Returning to server system

The SIGNOFF command ends the session and returns you to the sign-on display of the server system. When signed-on to the server system, the SIGNOFF command ends the current server job and returns you to the sign-on display of the server system.

You can use the end connection (ENDCNN) parameter of the SIGNOFF command to sign off the server system and end the TELNET connection. For example, signoff endcnn(*yes) returns you to your original session on the client system, or the previous session if you have more than one TELNET session established.

Notes:
  1. There is no limit the number of systems to which you can establish a Telnet session.
  2. The home system intercepts System Request options 13 and 14 if entered on the System Request input line. This function might be helpful if you establish a Telnet session with a system to which you cannot sign on. In this case, you can end a session to that system completing the following steps:
    • Press the System Request key.
    • Type 13 (Start system request at home system) on the System Request input line.
    • Type 2 (End previous request) on the System Request menu.
