Notes of Synolog NAS configuration

Setup package manager

Entware is the recommended package manager on Synology NAS. And this link actually uses an ansible script to automate the installation, which I should actually try!

use this script to determine the architecture of the NAS:

\
printf "\nProcessor:   "; \
cat /proc/cpuinfo | \
grep "model name" | \
grep "[^:]*$" -o  | \
uniq; \
printf "Architecture: "; \
uname -m; \
printf "\n"

Setup ssh login

What’s tricky is really the permissions you need to change:

admin@syno$ chmod700 .ssh
admin@syno$ chmod 644 .ssh/authorized_keys
admin@syno$ chmod 755 /var/services/homes/admin

• refer to: SSH without password on Synology DSM6.x

Setup Git Server

It’s easy to install the git server using package center. What could be tricky is to setup the user access:

• create a user named as git from control panel.
• grant git access in the git server (by opening the git server from installed packages in package center)
• also make sure a user folder is created for the git user, which can be done in Control Panel -> Users -> Advanced -> Enable user home service
• ssh to the synology server and create a git-shell-commands folder under ~git, e.g. mkdir ~git/git-shell-commands
• If a custom ssh port is used, you need to use the following git command to specify the ssh port:
  • git clone ssh://git@mydomain.com:[port]/gitrepo

Note I have run into issues related to the ssh access for the git user. And I find using the admin user seems the easiest to do (though definitely not a best practice to do, especially not feasible if there are multiple users)

Enable Rsync

By default, rsync is not enabled in synology DSM. To turn it on, navigate to Control Panel -> File Station -> rsync
