Is my SSH server vulnerable to MD5 or 96-bit MAC algorithms?

The remote SSH server is configured to allow MD5 and 96-bit MAC algorithms. The remote SSH server is configured to allow either MD5 or 96-bit MAC algorithms, both of which are considered weak. Note that this plugin only checks for the options of the SSH server, and it does not check for vulnerable software versions.

How do I find the supported MAC algorithms on a Mac?

The command “sshd -T | grep macs” shows the supported MAC algorithms, and all of the above are included (plus a bunch of the MD5 and 96bit algorithms).
