#Enable support for SSH on the Synology target machine
##Click the ''Control Panel'' Icon

#Allow the user, on the Synology target machine, to SSH
##Edit ''/etc/passwd''

#Add the authorized key of the client to the ''authorized_keys'' file of target
##on the client run ''ssh-keygen''
##copy the ''.pub'' file (likely something like ''/home/user/.ssh/id_ecdsa.pub'') to the target machine with a command like ''scp /home/user/.ssh/id_ecdsa.pub target_user@target_server:/var/services/homes/target_user/.ssh/id_ecdsa.pub''
##either rename ''id_ecdsa.pub'' to ''authorized_keys'' or copy the contents into your ''authorized_keys'' file.
#SSH once manually from the client machine (as the SSHing client user) to the target machine to add the target machine to the client's ''known_hosts'' file.
