JNC netconf client with ciphers support

We are using tail-f JNC client for netconf and we changed the confd.conf file so as to use
specific algorithms for encryption.

<ssh>
    <algorithms>
       <kex>diffie-hellman-group-exchange-sha256</kex>
       <mac>hmac-sha2-256,hmac-sha2-512</mac>
       <encryption>aes128-ctr,aes192-ctr,aes256-ctr</encryption>
     </algorithms>
   </ssh>

After this point we cannot connect and establish a session anymore from the client.

Are these ciphers supported by tailf -JNC ?

JNC is built on GANYMED SSH-2 FOR JAVA which doesn’t support SHA256. You can check the documentation for GANYMED on their supported algorithms.
