The CN1610 (software version 188.8.131.52) is failing Nessus TCP/IP security scans due to arcfour cipher being present.
I have fixed this via a hack;
vi /mnt/application/sshd_config (remove arcfour* )
kill <openssh PID>
opensshd -D -f /mnt/application/sshd_config
This works, however is not persistant over a reboot.
Can anyone advise on how to make this permanment or advise on a better solution to harden the ssh on the
