Issue
After an ONTAP upgrade to ONTAP 9.8x, older Solaris clients no longer connect via SSH:
% ssh -o StrictHostKeyChecking=no -l login password
Client and server could not agree on a key exchange algorithm:
client: diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
server: diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,curve25519-sha256@libssh.org
