  • Understood. Any public-facing server will be bombarded by bots. You need to deploy measures to avoid being hacked:

    1. Firewall: lockdown everything, allow only the strict necessary
    2. Remote login/SSH: update default username and pasword, only allow remote login using Encryption Key authentification
    3. (Optional) configure fail2ban to slowdown the attacks
    4. Keep your server up-to-date: configure auto-update, unattended-update or similare
    5. Setup and keep regular backups: be ready to nuke your server at anytime, with the confidence you can restart fresh in a short time and low effort

    Obviously, there are many other security steps that can be put in place, but firewall and ssh hardening are absolutely mandatory



  • I have tried openSCAD and FreeCAD, they are both good in their own right, but utimatly they also both have very steep learning curves. I suppose Blender can also be used for CAD but I have no experience with it. I just want to quickly design some parts for 3D printing as a hobby and don’t feel like spending hundreds of hours learning those tools. I am current using Onshape.com, it works well on Linux/Firefox, suits my needs and free to use with some limitations. But it is proprietary :(



  • I don’t think there is a one-fits-all solution. It depends what you are trying to do. For me it goes something like this:

    • transfer multiple files from 2 computers under my control: rsync
    • transfer few files between computers in my local network: NFS or SMB
    • tranfer 1 file from 2 computers in my control: scp
    • synchronize files between computers/phones: syncthing
    • synchronize files with cloud hosting: rclone
    • distribute files with relatives: cloud hosting, share link (I use pCloud, not FOSS)


  • Probably already mentioned in other comments, buy it can’t be stressed enough: Backups !

    Part of learning to use Linux is breaking it. You will make mistakes that will bork your computer. You can either spend hours to try to fix it, or you can wipe everything clean, reinstall, restore from your latest backup, and be done like nothing happend in no time. (Maybe you want to go the hard way for learning, but it’s always more relaxing to know you also have the easy option at your disposal)

    Ubuntu comes with Timeshift, make use of it. Also plan to make backups to external storage or NAS, in case things go real bad.
