It is not possible to run dhclient ifconfig and ifup unless running as
actual root. Using su -c "command" returns the misinformation that these
commands are not found. Personally I prefer using su -c from a user
account to bring up and take down the network while this was possible in
debian 2.4.27 it's so far not possible on speakup version of fedora out of
the box or updated.
