connection error: Could not negotiate diffie-hellman-group1-sha1

I get this error when I use Dameware SSH client for windows(Ver: 1.0.0.0) to ssh to some of my ESXi servers. Any idea how it can be resolved?

Error Message: connection error: Could not negotiate diffie-hellman-group1-sha1

Any help appreciated..

Regards,

I"m fairly positive that this error is a result of Orion using old, and in some cases, unsupported key exchanges for secure connections. The DNS SSH uses the same and my devices refuse to use anything less than sha256.

Should probably be fixed.

they should also move the ssh connectivity control mechanism to core so that it can be centrally managed rather than having a unique one per module (at least thats what it seems like, otherwise, NCM would have the same problem).

The issue isn't with Orion but rather with the "DameWare SSH Client for Windows". I am having the same issue with connecting to devices on the otherside of FortiGate firewalls.

I found this article on Fortinet that identifies this but it didn't seem to resolve the issue:
