[sentinix-list] Error trying to opendir

I recently installed Sentinix and am loving it.  I just finished configuring
the Nagios portion and am getting ready to move to the next task.  However
when I click on the "Network Tools" link I get the following error.  Being
fairly new to Unix I'm not sure how to resolve this issue.  Can anyone help?
Error!
Error trying to opendir("/tmp/shark.temp") - Permission denied (line number
2706 in "shark.c")! 

TIA
