PAM SSH Connections to An Oracle Server Are Failing

Products

• CA Privileged Access Manager (PAM)

Issue/Introduction

SSH connections from both Broadcom PAM and PuTTY (through a TCP/UDP service) to an Oracle server are failing. Confirm the required SSH algorithms supported by PAM.

Cause

The server host keys configured on the Oracle server (rsa-sha2-256 & rsa-sha2-512) were not in the default configuration of host keys used by PAM.

Resolution

The SSH Cryptography was updated in PAM and the two server host keys were added to the configuration, allowing SSH connections to be successful.
