I’m trying to setup remote execution of a script on my Vero when my NAS boots, which was something I had working before a recent reinstall. I’ve added the NAS RSA public key to the Vero authorized keys, and now am getting the following error when attempting to make an SSH connection from the NAS.
no matching mac found: client hmac-md5 server email@example.com,firstname.lastname@example.org,email@example.com,hmac-sha2-512,hmac-sha2-256,firstname.lastname@example.org
Can someone please advise whether this means that the SSH client on the NAS is out of date in some fashion, because it only supports hmac-md5, which the Vero SSH server isn’t supporting? I haven’t found anything specifically stating it’s an out of date message authentication code, but that’s the best understanding I have of everything I’ve read about SSH. I tried updating the SSH client on the NAS, but apt-get doesn’t appear to be present on there, and I can’t find anything on their wiki. Would it be wrong to try enabling hmac-md5 on the Vero SSH server?
