10 Great Things About FreeNAS

July 30th, 2009 Comments off

What is it that makes FreeNAS so special? Here is a list of 10 things which make FreeNAS great.

  1. It works – The thing about FreeNAS is that although the version numbers sound a bit freighting 0.69 or 0.7, it actually works. You can safely commit your data to it. Aside from hardware failure, power spikes or your roof collapsing the FreeNAS server will keep your data safe and sound.
  2. It is free – Unlike commercial NAS solutions FreeNAS is free as in that it costs $0 but also free in that the full source code is available for one. There are no hidden or proprietary secrets here.
  3. Low system requirements – How much does a hard disk cost nowadays, less that $100 for 1TB. If you have an old PC (and when I say old I mean a Pentium 2 or 3 not a 3Ghz Pentium 4 with 1GB of memory) then you can slip in a couple of 1TB drives (with maybe the addition of a new SATA controller) and your NAS is up an running. FreeNAS doesn’t need much memory, no fancy video card or a blinding fast CPU. My personal FreeNAS system runs on a 700Mhz Celeron system.
  4. Supports Windows, Mac, Linux and FreeBSD – It doesn’t really matter what type of computers you have in your home or office, FreeNAS probably will talk the right lingo.
  5. RSYNC – RSYNC is an incredible protocol for doing backups over your home network, over the internet or even internally in the FreeNAS. It is almost universally available on all platforms and is kind to your network or Internet connection.
  6. iSCSI – For those who are looking for more complex storage solutions, FreeNAS support iSCSI. Now that Windows has a free iSCSI initiator from Microsoft, iSCSI on FreeNAS can give you new hard drives in your PC without having to physically connect them!
  7. Media Streaming – FreeNAS supports several different types of media streaming and is uPnP compatible and can also act as an iTunes server.
  8. RAID – FreeNAS supports a whole plethora of RAID types including 0, 1 and 5 but also 1+0, 0+1, 5+0, 0+5 and so on.
  9. ZFS – With the advert of version 0.7 FreeNAS now officially supports ZFS the revolutionary filing system from Sun. With ZFS you data is organized into data pools rather than hard drives and to increase your storage you just add a hard drive to the pool. No more drive C:, D:, E:, F:, G:, H:…
  10. Easy to use – Even though FreeNAS is built on top of FreeBSD, you don’t need to get your feet dirty with technical Unix type things. FreeNAS is managed with a web interface. Simple, clean and easy to learn.

Using FreeNAS for Disaster Recovery – Part 1 and 2

July 27th, 2009 Comments off

Saiweb has a series of posts about using FreeNAS for disaster recovery.
They were looking for ways to build a “cost effective” NAS, and now following the success of a recent build using FreeNAS for deploying an office NAS with 2.7TB of usable disk space they have developed a concept for using these relatively cheap NAS systems for Disaster Recovery Purposes.

This NAS build at the time of writing costs £740.54 inc VAT, for a 4TB system, giving approx 2.7TB of usable diskspace in a RAID 5 configuration, try getting a pr-ebuilt model for that!

You can find links to part 1 and part 2 of this series below, I will of course keep you up to date with any news posts which appear!

NAS Showdown: FreeNAS vs AirPort Extreme vs Synology DS207+

July 27th, 2009 Comments off

The Good Tech Tips blog has posted a showdown between 3 different types of NAS: A DIY FreeNAS system, an AirPort Extreme with attached USB drive (pictured) and a Synology DS207+.

To evaluate the usefulness of each financial step up, they used three main criteria: Overall performance, availability of redundant data via RAID 1, and whether it’s possible to add in features like media streaming, remote access or integrated BitTorrent.

Here are the details of the 3 system tested:

  • A DIY system was concocted using FreeNAS software and an older ThinkPad. This was technically the cheapest of the bunch.
  • A router-based system was an AirPort Extreme with attached WD and LaCie USB drives, which was also “recycling” but cost a bit more.
  • The dedicated NAS appliance tested was a two-drive Synology DS207+, $330 for the box but the drives themselves are sold separately.

Follow the link below to find out the final verdict.

How to Connect to Your FreeNAS Server via SSH Without A Password; Password Free Logins via Public Key Authentication

July 22nd, 2009 4 comments

If you connect to your FreeNAS server often with SSH or want to run rsync via SSH then it can be very useful to setup what is called public key authentication. In public key authentication rather than using a password to grant access the SSH client and the SSH server exchange keys and so confirm the identity of the client.

The firs step is to make sure that you have a user with shell access. To check goto Access->Users and either edit and existing user or create a new user and make sure the “Shell access” box is ticked. You also need to be sure that the SSH server is running. Check this on the Services->SSH page.

SSH is very fussy about user permissions. If the home directory of your user isn’t owned by the user, SSH login with public key will fail. If you have this problem the SSH log will show something like Authentication refused: bad ownership or modes for directory /mnt/store. To fix this you need to create a directory beneath your mount point for that user, i.e. /mnt/store/bob and the Home directory needs to be set to this on the Access->Users page for that user.

In this example I will use OS X (it should be almost identical for Linux but for Windows users you will need to use PuTTY and PuTTYgen).

On the client machine open a terminal window and enter the command:

ssh-keygen -q -f ~/.ssh/id_rsa -t rsa

When prompted for a password just hit ENTER twice:

Enter passphrase (empty for no passphrase):
Enter same passphrase again:

This will generate what is known as a private key and a public key. The private key must be kept save and secure and you must never distribute it in any form whatsoever. However the public key is for public consumption and this is what we will copy over to the FreeNAS server.

So to copy the public key to the FreeNAS server, user the following command:

scp ~/.ssh/ bob@

Where bob is the username with shell access and is the address of your FreeNAS machine.

When prompted for the password enter it:

bob@’s password: 100% 402 0.4KB/s 00:00

Now login to your FreeNAS machine using SSH:

ssh -l bob

And enter the password when prompted.

Now the public key of your client machine needs to be added to the list of authorized clients that connect. To do this run the following commands:

cat ~/ >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
rm ~/

The first command will add the key to the list of authorized keys, the second will ensure that the permissions are set correct on that file and the third will delete the .pub file you copied over with the scp command as it is now longer needed.

And that is it. You can now logout and now connect again with SSH and it should connect directly without asking for a password.

If you find that everything doesn’t work as planned they check the Diagnostics->Log page and select SSH from the drop downbox and see what is being logged.

Bittorrents in FreeNAS

July 21st, 2009 Comments off

The guys over at Ejes Consulting have been playing around with FreeNAS a lot lately. Among the many features that they enjoy in the FreeNAS project, one of their very favorites is the Bittorrent Server that it has built in.

It is a version of the Transmission bittorrent web client running in WebGUI mode (by default on your freeNAS server on port 9091 http://freenas:9091 or similar)

The features that they want specifically is the blocklist feature, which allows you to download a list of blocked ips from known malware locations or otherwise malicious sites, and the ability to encrypt traffic so that your ISP cannot detect your bittorrent traffic.

You can see the full guide at the link below.
