\section*{Using SSH with the SeaBeaver II (SB2) AUV}
%====================================================================

Normally when using the secure shell utility, \cmd{ssh}, you will be
prompted for your password on each interaction. While secure, this can
cumbersome if such events are more frequent than say once per half
hour.  Certain tools, like SVN, use \cmd{ssh} as underlying utility to
handle authentication. This can also lead frequent entry of your
password, perhaps several times within a minute, depending on your
task.
