Unable to do passwordless login to FreeNAS

Question

I'm trying to use this command to allow me passwordless login to a FreeNAS box:

cat ~/.ssh/id_rsa.pub | ssh root@server.com 'cat >> ~/.ssh/authorized_keys'

But I get:

/root/.ssh/authorized_keys: Read-only file system.

If I log in to box as root, then ls ~/.ssh I see

drwx------  2 root  wheel   512 Aug 22 18:34 ./
drwxr-xr-x  3 root  wheel   512 Sep  1 19:16 ../
-rw-r--r--  1 root  wheel   806 Aug 22 18:39 authorized_keys
-rw-------  1 root  wheel  1675 Aug 18 21:50 id_rsa
-rw-r--r--  1 root  wheel   400 Aug 22 18:34 known_hosts

And if I ls ~ I see

drwx------   2 root  wheel   512 Aug 22 18:34 .ssh/

What am I missing? Why can't I add an entry to known_hosts?

Login to your FreeNas Machine and open the Terminal enter:

mount -o rw /

when done enter

mount -o ro /
