How to repeat:
ssh host:mysqldevdb.its.bethel.edu:22

mysql hostname:localhost
mysql user:root

[remote managment ]
ssh login based managment
host name :ssh-2.its.bethel.edu
username johmicd
check auth enticate useing ssh keys
ssh key path /Users/johmicd/.ssh/id_rsa

tried puting in paramiko 1.15.1 and ecdsa and this did not change much
