The Debian distribution we are using comes with two users:
root
and
debian
. The
bash
command window for Cloud9 runs as
root
; you can tell this by looking at the last
character of the prompt. If it's a
#
, as shown here, you are running as
root
. If it's a
$
, you
are running as a normal user (
debian
).
NOTE
In this topic, we assume that you are running as
root
.
WARNING
root
is also known as the superuser. Running as
root
, you can access most everything on
the Bone. This is both good and bad. If you know what you are doing, you can easily interact
with all of the hardware. But, if you don't know what you are doing, you can really mess
things up. If you follow our examples carefully, you shouldn't have any problems.
WARNING
Initially, the
root
password isn't set, so anyone can log in without a password. This may be
OK if your Bone is never connected to the network, but it's better practice to set a password:
bone#
passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
For security, the password you type won't be displayed.
