Cisco UCS and Solarwinds SFTP Issue? - OpenSSH

I need your help for SolarWinds SFTP server.



Problem is that the SFTP from Cisco UCS to SolarWinds has stopped functioning in the Cisco UCS Code 4.1.3B and above.


Please review documented issue below – seems to point to OpenSSH.


That article was SolarWinds was based on version V19 and it still does not work in 21.


I’m sure you have a workaround that I can do for the SolarWinds SFTP server for this. Maybe certain crypto functions that need to be enable?  Let me know


With Cisco UCS Manager 4.0(2a) release and later, certain insecure ciphers are blocked by UCS Fabric Interconnects.

In order to log in to servers through the secure protocol, you must use a version of OpenSSH that supports at least one algorithm in each of the three categories:

 Key exchange algorithms diffie-hellman-group-exchange-sha256 diffie-hellman-group16-sha512 diffie-hellman-group18-sha512

 Encryption algorithms aes128-ctr aes192-ctr aes256-ctr

 MAC algorithms hmac-sha2-256 hmac-sha2-512
