Basic Info

  • Web interface at http://files/
  • Can also be accessed via samba/SMB with the standard lvl1 credentials.
  • ssh is also possible, but there is no safety check for accidentally deleting files this way.

Setting up on Ubuntu

  • Prerequisites:
sudo apt-get install autofs smbfs
  • create autofs config files
  • /etc/auto.master
/mnt   /etc/auto.files    --timeout=6000    --ghost
  • /etc/auto.files
z    -fstype=smbfs,credentials=/etc/auto.auth    ://files/shared
  • /etc/auto.auth
    • (replace CENSORED with the lvl1 credentials)
username=CENSORED
password=CENSORED
  • run the following:
sudo chmod 400 /etc/auto.auth
sudo service autofs restart
  • the files share will be mounted in /mnt/z
  • to make this easily accessible, run
ln -s /mnt/z ~/z
  • Desktop file for adding to menu (place in /usr/share/applications/

Server Setup

File Systems

Device

  • Root is on a single drive. Important files are symlinked to the raid array.
  • Raid device is /dev/md0
    • Do not access this directly
    • Check status with
cat /proc/mdstat
  • Cache device is /dev/bcache0
    • This adds SSD caching on top of the /dev/md0
    • Interact with /dev/bcache0 as if it were a disk.
    • Mounted on /mnt/bcache0

Samba

  • Samba is used to share files and provide a recycling mechanism
  • Services like elFinder that access member files use a mounted samba share so that samba can protect files from being deleted
  • Config file: /etc/samba/smb.conf

Autofs

  • Used to mount the samba share locally
  • Config files
    • /etc/auto.master
    • /etc/auto.files
    • /etc/auto.files.auth
  • Dir
    • /mnt/autofs/z

ClamAV

  • Virus scanner
  • Currently I only have a cronjob setup to manually scan the shared directory
  • cronjob /etc/cron.hourly/clamav
  • scans /home/lvl1/shared/
  • moves infected files to /home/lvl1/infected/
  • logs to /var/log/clamav.log

CloneZilla

This is the process for backing up computers to the file server.

  • Boot a clonezilla iso
  • Clonezilla Live
  • device-image
  • ssh_server
  • dhcp
  • 10.0.0.10
  • 22
  • lvl1
  • /home/lvl1/images
  • yes (if it asks for ssh key)
  • Beginner
  • disk device
  • I lost track here... but you should be good.
