Useful documentation

After installing FreeNAS the User Guide documentation for the current version is available in the "Guide" tab.

Setting up a FreeNAS box

Go through the installation process. After the install make sure that you have the correct address assigned to the box. If not you could use the console menus to set it or drop to a shell.

Using the shell:

ifconfig

Lists all the interfaces and note the interface you want to use

ifconfig <interface> inet <IPv4 address/subnetmask> add

Sets the IPv4 for the interface you want to use

ifconfig <interface> inet <IPv4 address> -alias

If you by accident set a address to the wrong interface

route add default <gateway address>

Sets the default gatway

service nginx restart

Nginx needs to be restarted since it does not serve on the correct address.

Disable the console menu

Go to System/Advanced:

Enable Console Menu = false

Certficates & syslog server

Make sure that you start by using https, for this you need to have a valid certificate. You could if there for the moment are no signed certificate for the machine, generate a self-signed certificate.

To enable https and set syslog server, go to System/General:

Certificate = your certificate
Protocol = HTTPS
WebGUI HTTP -> HTTPS redirect = yes
Syslog server = <Logserver with FQDN>

Kerberos

Generate a kerberos keytab on a machine that is inside the kerberos realm for your new machine and export it.

NIS

Setup NIS settings: Directory/NIS

NIS domain = lysator
NIS servers = nis.lysator.liu.se,ns-slave.lysator.liu.se
Secure mode = yes
Enable = yes

And save.

NFS

Setup the default nfs server settings: Service/nfs

Number of Servers = 6
Serve UDP = yes
Enable NFSv4 = yes
support > 16 groups = yes
Log mountd = yes
Log rpc.statd & rpc.lockd = yes

Firewall

Setup pf on the FreeNAS box

pf.conf example:
