Automated scripts on an AIX system require secure non-root access to another AIX instance. Secure Shell (SSH) was the method chosen and installed on both systems. How can an administrator use SSH to…

This option specifies an incorrect or incomplete destination path for the authorized_keys file, which must reside in the target user's ~/.ssh/ directory to function correctly.

Generating the key as root and placing it under /etc/ssh/ is incorrect because the question requires non-root access, and system-wide key files in /etc/ssh/ are not used for per-user passwordless authentication.

This option points to an incorrect destination path for the authorized_keys file on the remote system, which would prevent the public key from being recognized during authentication.

Running ssh-keygen -t dsa as the non-root user on the source system generates an id_dsa private key and id_dsa.pub public key in ~/.ssh/. Appending id_dsa.pub to the target non-root user's ~/.ssh/authorized_keys on the destination enables fully passwordless, key-based SSH authentication, satisfying both the security requirement and the need to avoid storing passwords in automated scripts.
