telnet Implementation. When you attempt to use the telnet command to enter a system that is being used by another telnet connection, the system displays:

Sorry, this system is engaged by another telnet session. Host IP address: xxx.xxx.xxx.xxx

Logout the other telnet session? (Y/N) y

Enter Password: correctpassword

The first telnet session is disconnected and the system displays:

LOGGING OUT the other telnet session.

You can then connect in the usual manner.

CAUTION: When you preempt a telnet or rlogin session in this manner, the current session user receives no notice that the session will be disconnected.

If you enter an incorrect password, the system displays:

Incorrect password. Disconnecting.

The system disconnects after it receives three incorrect attempts at the Administer-level password.

If you respond n to the request to disconnect, your session disconnects and the original connection remains established. The system displays:

Disconnecting

If you respond y at the Logout the other telnet session? prompt and it is not accepted, it is probably because of the telnet configuration on the UNIX host. To force the system to accept your response to the prompt, follow these steps:

1Escape to the telnet session by pressing Ctrl+}

2Set the cr/lf option by entering either of these commands:

set crlf

OR

toggle crlf

Press Return or Enter to redisplay the prompt. Your response should now be accepted.
