I have problems with severeal OmniSwitch series e.g. OS6850 (126.96.36.1990.R01), OS6400 (188.8.131.527.R01). The problem is that it's unpossible to connect via ssh2.
The error message via cli is:
The error message from OmniVista backup is:The client has disconnected from the server. Reason:
Invalid packet header. This probably indicates a problem with key exchange or encryption.
After connecting to the device via https and a login the ssh2 connect works for a few times but after a while the error recurs.Error (Failed to backup configuration for device: x.x.x.x. SSH2Exception: Key exchange failed: Invalid packet size: 173299013.) at backup configuration
Any idea how to fix this or need more information?
