Yes. Each of the PCs has its own serial console line with which you can
interact, either directly from your desktop (see next FAQ entry),
or by hopping through the "users" machine,
using our <tt>console</tt> program. To connect over serial line to
"pc1" in your experiment, ssh into <b>users.emulab.net</b>, and
then type <tt>tip pc1</tt> at the unix prompt. You may then
interact with the serial console. The console output is also saved
for each node so that you may look at it it later. For each node,
then type <tt>console pc1</tt> at the Unix prompt. You may then
interact with the serial console (hit "enter" to elicit output from
the target machine).

In any case, all console output from each node is saved
so that you may look at it it later. For each node,
the console log is stored as <tt>/var/log/tiplogs/pcXXX.run</tt>.
This <em>run</em> file is created when nodes are first allocated
to an experiment, and the unix permissions of the run files permit
just members of the project to view them. When the nodes are
to an experiment, and the Unix permissions of the run files permit
only members of the project to view them. When the nodes are
deallocated, the run files are cleared, so if you want to save
them, you must do so before terminating the experiment.

The Sharks also have serial console lines, but because of the
limited number of serial ports available on <b>users.emulab.net</b>, only
one Shark, the last or "eighth", on each shelf has a console line

sh16-8 as an example, the shelf number is sixteen, and the number
of the node on the shelf is eight.
