Platespin Recon inventory fails with failed to negotiate a transport component

This document (7018544) is provided subject to the disclaimer at the end of this document.

Environment

NetIQ PlateSpin Recon 4.x

Situation

While attempting to inventory a Linux workload Platespin fails with:

            Failed to negotiate a transport component 3des-cbc

Resolution

Check /etc/ssh/sshd_config and verify the following lines are set:

Ciphers 3des-cbc

KexAlgorithms diffie-hellman-group1-sha

Once changed restart the sshd service.

Cause

This can happen when manually specifying sshd ciphers and excluding 3des-cbc or because the operating system vendor no longer allows 3des-cbc as a default cipher in sshd.

Additional Information

Please verify all changes with your system administration team before making changes to sshd. Incorrectly modifying /etc/ssh/sshd_config can cause sshd to no longer start.

Also please verify that 3des-cbc is supported by any software leveraging ssh or modify the Cipher line to include any other required ciphers.
