How to build a FreeNAS box the way!

July 23rd, 2010 Comments off

Bit-tech have posted an excellent tutorial on “How to build a NAS box” which includes both the hardware aspects and the software, which in this case is FreeNAS.

“A NAS – or Network Attached Storage box is the easy and increasingly popular answer because you can simply drag and drop files to/from any PC… NAS boxes are a very low power way to store masses of data, while also giving everyone on the network access to that data.”

As they go on to say there is a certain satisfaction from doing stuff yourself.

The tutorial covers:

  • How to build a NAS box
  • The Best NAS Hardware: Hard Drives and RAID Cards
  • The Best NAS Hardware: CPU and Motherboard
  • The Best NAS Hardware: Memory, Case and PSU
  • BIOS Setup – Underclocking and Undervolting to Save Power
  • FreeNAS setup
  • Using FreeNAS for Bit Torrent

How to Secure Your FreeNAS Server

February 24th, 2010 2 comments

Via the FreeNAS forum, Phan Vinh Thinh has posted some details on how to secure your FreeNAS server.

  1. Change the WebGUI admin/root password (the default is: freenas)
    Use a very strong password if you intend to access FreeNAS over the Internet.
    Please note – admin/root accounts use the same password.
    Please note – Users that are members of the wheel group can su to root if they know the root password.
  2. Change WebGUI admin user name (the default is admin), to protect your system against dictionary attacks.
  3. DO NOT give shell access to everybody.
  4. DO NOT use FTP over the Internet, use SSH or SFTP instead.
  5. DO NOT enable Password Authentication with SSH, set-up and use SSH key based authentication.
  6. Always use https protocol to access WebGUI interface.
  7. DO NOT open your WebGUI server to internet, rather open a tunnel via SSH from client to server.

Growing Mirrored and Encrypted Partitions in FreeNAS

November 6th, 2009 Comments off

Alexander Kojevnikov has set up a FreeNAS server using RAID 1 (AKA mirroring) and encryption. But is asking himself the question what if, in the future, I want to upgrade the drives with larger ones?

A common scenario with RAID 1 is to replace one of the disks with the bigger one, rebuild the mirror then replace the other one and rebuild it again. In theory it sounds like an easy process that will keep all your data intact. In practice however it’s not,

Alex has found a post by Mike Oliver called FreeNAS 0.7.3953, RAID 1, growfs… oh my! explaining how to do this under FreeNAS.

However if you add encryption it is a little more complicated… Thankfully Alex’s post as the procedure needed!

How You Can Build a Media NAS For Next to Nothing Using FreeNAS

October 9th, 2009 Comments off

Marton Pipe of Home Cinema Choice has written a guide about using FreeNAS for media storage.

“If you have an old PC sitting around it’s surprisingly easy to create a NAS (Network Attached Storage) repository for your media.”

“For the purposes of this project, I spent a mere £20 on a six year-old Evesham 2.8GHz Pentium 4 (i.e. single-core) with 512MB of RAM (pictured above).”

“FreeNAS provides many useful features. As with commercial NAS boxes, a built-in webserver allows you to remotely administer it from a PC on your network – just enter the IP address that it can automatically derive via DHCP.”

FreeNAS Bash Script to Start a ZFS Scrub on Each Pool

August 31st, 2009 Comments off has published a script which performs a scrub on each pool. ZFS automatically checks for errors when it reads/writes files, but you can force a check with the scrub command.

After uploading the script to your FreeNAS machine, suggest you make it run automatically, by going to System –> Advanced –> Cron and add it as Monthly cron job.

You can find the script here:
