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.

See the rest of his blog entry for a brief tutorial on implementing these steps Phan’s blog: How to secure your FreeNAS server

Some more details are starting to emerge about what will appear in FreeNAS 0.8:

Planned major features:

• Development on FreeBSD RELENG_8. Release, depending on timeframe may be based on a RELENG_8 snapshot or 8.1-RELEASE
  
• Migrate off m0n0wall
  
• Migrate GUI to django
  
• Add support for ada and ahci SATA drivers
  
• Add optional SoftUpdates + Journaling support to UFS2 filesystems
  
• Migration path/tool for previous releases and configurations
  
• Preservation of all existing features of the current FreeNAS release
  
• Refactor FreeNAS build system to allow building FreeNAS without affecting the host environment
  
• Non-Blocking Features
  

Possible other features

• FreeNAS package support. Binary one click installs that modify the GUI dynamically.
  

I am sure this list will evolve and you can keep an eye on the current developments here: http://freenas.org/roadmap

Permanent restrictions:

• It is not possible to format a SoftRAID disk with MSDOS FAT16/32.
• It is not possible to encrypt a disk partition, only complete disks are supported.
• It is not possible to get seperate CPU stats per processor on SMP machines because FreeBSD does not support that feature.
• Enable ‘polling’ on interfaces used by a LAGG interface will make it inoperable.
• It is not possible to mount EXT2 disks with an inode size of 256 bytes. You have to format it with 128 bytes on Linux to use them on FreeBSD.

Known bugs:

• If DHCP for IPv4 is used, the IPv6 statically configured DNS server will be overriden by the IPv4 DNS server.
• Downgrading to 0.69 via WebGUI fails because of broken pipe error.
• FreeBSD’s ext2fs module, as of release 7.1, cannot mount ext2 file systems with 256-byte large inodes, only 128 byte sized. Unfortunately, 256 byte is the default size with many recent Linux distributions.

Today Olivier Cochard-Labbé has made a great announcement, FreeNAS will live on and production ready ZFS support will be added with the upgrade to FreeBSD 8.0. At the same time a new Linux version of FreeNAS will be created called OpenMediaVault!

Olivier explained it like this: FreeNAS needs some big modification to remove its present limitations (with one of the biggest being the lack of support for add-ons/plugins). We think that a full-rewrite of the FreeNAS base is needed. Therefore, we will take 2 different paths:

1. Volker will create a new project called “‘OpenMediaVault” based on a
   GNU/Linux and use all his experience acquired with all those nights and week-ends spent improving FreeNAS during the last 2 years. He will still
   continue to work on FreeNAS (and try to share his time with these two
   projects).
   
2. And, a great surprise: iXsystems (http://www.ixsystems.com/), a company specialising in professional FreeBSD systems has offered to take FreeNAS under its wing as an open source community driven project. This means that they will use their professionals FreeBSD developers to better FreeNAS! Their manpower will permit a full-rewriting of FreeNAS.
   

Olivier also added that he will personally come back to actively working on FreeNAS and begin to upgrade it to FreeBSD 8.0 (which is “production ready” for ZFS).

This is brilliant news all round and I think Volker and Olivier should make sure that the two projects share as much code as possible. Also I think iXsystems should be congratulated for their support of FreeNAS.

Harrdy has gleaned this information from this forum thread

In short… FreeNAS 0.8 will be based on Debian GNU/Linux! Volker (the core developer) started an intermediate project called CoreNAS. FreeNAS 0.8 will be based on that.

Here is a short list of pros by Volker:

• Text and graphical installer that can be customized. This means no hand written install scripts anymore which causes some problems in FreeNAS
  
• WOL works in Linux
  
• lmsensor - A WORKING sensor framework which is a really needed feature in FreeNAS to check the CPU/MB temps and fan speeds
  
• Better Samba performance
  
• Ability to implement HA features
  
• System can be updated via ‘apt-get’ or any other deb package manager
  
• Better driver support
  
• Maybe ‘ZFS’ over FUSE (there is already one commercial product available that uses this feature)
  
• NFS4
  

ZFS
The really big problem is ZFS… If it is Linux under the hood or FreeBSD it really doesn’t make that much different to the end user, but and it is a big but, Linux doesn’t have (and can’t have due to licensing issues) ZFS and really running ZFS under FUSE is not a real option.

Is it time for someone else to take up the development of FreeNAS where 0.7 and Volker left off?

Since then he has been a die hard open source fan and has used Linux, LTSP (the Linux Terminal Server Project) and FreeBSD. Todd has recently discovered FreeNAS and has written all about it (see the link below).

Here are a few choice snippets:

“FreeNAS works fine with an old Pentium III (933 MHz), showing only 1 percent CPU usage and 20 percent of the 1 GB total of RAM. I’m not exaggerating, the thing screams.”

“It is elegant in function and a perfect option for us to continue to give even more data services to everybody here in Birmingham even while our budgets have been tightened.”

Majors changes:

• Add ability to configure the login shell for a user.
  
• Local users must join the group ‘ftp’ to be able to login via FTP if ‘Local users only’ in ‘Services|FTP’ is enabled.
  
• Add a user portal. This allows a local user to login and change it’s
  password. The user must have access permissions to login to the user
  portal.
  This can be configured in the user configuration WebGUI. Please note that
  the administrator needs to apply changes done by the local users because
  there have to be restarted several services (which is not allowed to be
  done by a user).

  directory (BR 2795084).
  
• Synchronizing ZFS configuration fails (BR 2814324).
  
• Restrict bittorrent administrative WebGUI port to [1024,65535] (BR
  2835342).
  
• The ‘Unmount disk/partition’ checkbox on ‘Disks|Mount Point|Fsck’ was ignored (BR 2860297).

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!

The tutorial is quite advanced and not only covers booting, installation and initial configuration but also covers RAID.
