Sync Files to Your Computer

How to Sync Google Drive and OneDrive Files to Your Computer

Microsoft Onedrive

For NIH one drive,

  • we can only share with NIH users.
  • When sharing a file, the receiver needs to sign in through their browser and if the files are large, it cannot be opened online and needs to be downloaded to local first.
  • we need a PIV card in order to see oneDrive online.
  • it seems we cannot use oneDrive as a backup. If we unselect a folder for syncing, the folder will be immediately removed from the local system.
  • not sure if the syncing is working. I copy a new folder to the local onedrive folder. The oneDrive icon on the top menu keeps rotation but nothing really happened. The new files are not in cloud and the syncing symbol shows files are not synced.

Oracle cloud

  • https://oracle.com/cloud/
  • 【甲骨文】云服务器免费注册地址大全！
  • Be sure to keep SSH keys since there is no way to retrieve it
    • For some reason, suddenly I cannot ssh connect to my VM after I installed and ran the calibre docker container.
    • On another machine, my ssh connection got kicked out client_loop: send disconnect: Broken pipe
    • The console connection method still relies on SSH, which doesn't solve your original problem. Unfortunately, Oracle Cloud Infrastructure (OCI) doesn't provide a direct, non-SSH method to access the command line of your VM through the web interface, unlike some other cloud providers.
  • Hamburger icon on top-left -> Billing and cost management.
  • Difficult to create VMs: Out of capacity for shape VM.Standard.A1.Flex in availability domain AD-2. Create the instance in a different availability domain or try again later. If you specified a fault domain, try creating the instance without specifying a fault domain, otherwise try creating the instance in a different availability domain. If that doesn’t work, please try again later.
    • Out of capacity for shape VM.Standard.A1.Flex
    • Change A1.Flex to A2.Flex will help but A2.Flex is not always free
    • VM.Standard.E2.1.Micro is always available. But we are limited to
      • 2 instances.
      • RAM = 1GB No cache in VM. So if we ran out of memory, the machine will be frozen. Need to reboot.
      • Network bandwidth is .48 rather 1 GB/s.
  • Linux distribution
    • Ubuntu default username: ubuntu (about 240 MB RAM, Lightest image on RAM for micro instances)
    • Rocky linux default username: rocky. Rocky linux is way too heavy and slow on E2.1.Micro. "dnf update" takes long time. Why total memory is 760MB instead of 1GB.
  • Post installation
    Fix date/time (works for Ubuntu & rocky) 
    sudo timedatectl set-timezone America/New_York
  • Open ports 
    sudo apt install firewalld
sudo firewall-cmd --zone=public --permanent --add-port=8080/tcp
# sudo firewall-cmd --zone=public --permanent --remove-port=8080/tcp
sudo firewall-cmd --reload

sudo firewall-cmd --state9
sudo systemctl status firewalld
sudo firewall-cmd --list-all
sudo firewall-cmd --list-ports  # list open ports

    Or (not tested). 

    sudo apt install ufw
ufw --version
sudo ufw enable
sudo ufw allow 80/tcp
sudo ufw status

    Step 2. Click on my Virtual cloud network vcn-2024xxxx-xxxx. Subnets -> subnet-2024XXXX-xxxx -> Security Lists -> "Default Security List for vcn-2024XXXX-xxxx" -> Ingress Rules -> Add Ingress Rules. Currently the rules contain port 22. So I just add port 8080.

Idle instance reclaim

Always Free Resources

Idle Always Free compute instances may be reclaimed by Oracle. Oracle will deem virtual machine and bare metal compute instances as idle if, during a 7-day period, the following are true:

  • CPU utilization for the 95th percentile is less than 20%
  • Network utilization is less than 20%
  • Memory utilization is less than 20% (applies to A1 shapes only)

Minimal Ubuntu in Oracle Cloud

This system has been minimized by removing packages and content that are
not required on a system that users do not log into.

To restore this content, you can run the 'unminimize' command.
  • htop shows 197MB (vs 247MB) on Ubuntu 24.04.1 LTS.
  • It's optimized for cloud environments and automated deployments.
  • It has a smaller footprint, faster boot times, and requires fewer security updates.
  • It lacks many convenience tools typically found in standard Ubuntu Server installations. For example, manual pages, text editors, network diagnostic tools,...
