Can't do wget

[sg4rb0]

I want to do a wget to install iperf, but the problem is the error below:

Cannot write to 'iperf_2.0.2-4_amd64' (Read-only file system).
I can't tell you how annoying this is because I don't know how to fix it. On the internet it said something about re-mounting stuff as writable. I'm really a novice and I need help. Here is my mount output:
[root@freenas] ~# mount /dev/ufs/FreeNASs1a on / (ufs, local, read-only)
devfs on /dev (devfs, local, multilabel)

Please advise me how to fix this. I already had a tonne of problems today with FreeNAS, it's very cumbersome.

Have you tried the installed version of iperf on FreeNAS?
On the latest RELEASE iperf version 2.0.5 (08 Jul 2010) is installed.

Just did a pkg_info | less and it looks like its already installed. Didn't realise! I wouldn't mind understanding what the point of only making root read only is on the filesystem though. Makes no sense to me what so ever. Can you tell me how I can change that in case I need to install something else at a later date?

FreeNAS is an appliance, not a general purpose server. If you need other apps installed you will need to use jails. The usb drive with FreeNAS has very limited free space as well (megabytes).
