Problems SSHing from ACS 5.2

[glearmon]

When I try to SSH from ACS 5.2 CLI to my SFTP server I get :

Unable to negotiate a key exchange method.

On the SFTP server (Tectia) I have the encryption configured with aes256 and hmac-sha1.

Any help appreciated.

Thanks,

Hi there!

What about the Key exchange cipher? Is it diffie-hellman-group14-sha1?

Thanks - I don't know - that was the first thing I tried to check on the Tectia sevrer side but the Tectia config doesn't seem to mention what cipher exchange is used or provide a way to change it.
