I just wanted to make sure that I can reproduce this from scratch, for
anyone who's interested...
Fresh install from 10.04.3 CD, choosing openssh-server as the only

$ sudo -s
$ apt-get update
$ apt-get dist-upgrade
$ aptitude install iperf
...
test network speed - all OK
...
$
Here are the results:
