Operating System
All Platforms
Symptom
When creating a backup set on a VMware ESXi 6.0 Update 2 host the following error is displayed by AhsayOBM:
Cannot connect SSH, please check the SSH settings
Cause
This issue can occurs, because VMware ESXi 6.0 Update 2 is embedded with OpenSSH 7.1, which disables older cryptographic algorithm such as diffie-hellman-group1-sha1.
Resolution
To resolve the issue, patch the AhsayOBM application to version 7.11.0.4 or above.
This issue affects a legacy version of our software. We strongly recommend upgrading to the latest AhsayCBS and AhsayOBM release (v9.15.0.0, as of 2025/May/15) for improved performance, compatibility, and security.
