Hi Nick,

Sorry for providing incorrect information, the customer device is
configured to use the following Kex algorithm and not "KexAlgorithms
diffie-hellman-group16-sha512".

   - diffie-hellman-group-exchange-sha1
   - diffie-hellman-group14-sha1
   - diffie-hellman-group1-sha1

   Ciphers*: *aes256-cbc
   MAC: hmac-sha1

   I have sorted out attached debug logs from the production server and
   will be easy for you to look at.

   We performed some testing with a customer device by using ssh client
   JSCH.4.0.0 which worked fine but the ssh connection did not work with
   guacamole 1.0.0.

   We upgraded  guacamole from 0.9.3 to 1.0.0 in May 2019 and customer
   reported that ssh to their Cisco devices stopped working which was
   working till the time they reported the problem to us.


   Regards,
   Abhijeet Jha
