Hello community,
I have been using Linux on the desktop for many years now, but unfortunately my knowledge about servers is very limited, almost non-existent. Therefore my question is most probably equally well fitting here and into the newbie corner.
I'm trying to set up a little home server on a Raspi using Arch ARM. It should be in charge of following tasks:
- CUPS print server in the local network
- access to shared files through NFS in the local network
- backup (again over NFS)
- an Owncloud server
- maybe a mail server in the long run (NSA, paranoia, etc.
)For now I have set up the print server, the NFS server and was working on the Owncloud installation, when Owncloud gave me some errors with users and permissions. So I was led to the idea of rethinking the users and permissions on the Raspi. So far there is only the root user who may do everything. This seems like a quite unsafe configuration. I'd like to make it safer. First, the printer, the backup and the locally shared files should be accessible from the local network only. SSH access should also be accessible locally only. The Owncloud file folder should be accessible from the internet, but of course only for the Owncloud users registered to the Owncloud server.
What is the best way to set up users and permissions for such a set up?
Thanks for any hints,
PhotonX
