Subject: rabbit ssh from macOS

Stephen,

Here is the notification I sent:

A recent Apple update by default disables the ssh-dss key algorithm 
used by rabbit's ssh server which can cause login problems from macOS.
There are two fixes: 

1. Login with ssh -o HostKeyAlgorithms=+ssh-dss username@rabbit.eng.miami.edu 

OR 

2: check /etc/ssh/ssh_config or /etc/ssh_config file and make sure that the 
   HostKeyAlgorithms line is un-commented and includes the ssh-dss.

Nigel.
