Resolving The Problem
Bypass sign-on seems to fail when performing Telnet from one IBM i to another even though a valid user ID and Password are being used.
When prompting the Telnet command, by pressing F10, additional parameters for the connection are available. User ID and password are two such parameters that can be used to bypass the Telnet host's sign-on screen.
It should be noted that when using these two parameters to bypass the sign-on screen for another IBM i host, that host must have the System Value. QRMTSIGN must be set to *VERIFY. Also, the Remote password encryption field must also be set in order to bypass sign-on. The Help Text for the Remote password encryption field reads as follows:
If the remote system is running OS/400, you should set this parameter based on the release level of the remote system and the system value QPWDLVL on the remote system:
o If OS/400 on the remote system is at release level V4R5 or earlier, specify *DES7.
o If OS/400 on the remote system is at release level V5R1 or later, and QPWDLVL has a value of '0' or '1', specify *DES7.
o If OS/400 on the remote system is at release level V5R1 or later and QPWDLVL has a value of '2' or '3', specify *SHA1.
By changing the value as specified, the bypass sign-on feature works as intended.
