updated check_traffic scripts

[Michael S. Kazmier]

Okay folks,

 

I have patched the make_config script to correctly produce the correct RRD
files, descriptions, etc.  I have also created a script I call set_perms to
run AFTER the make config that will correctly set the permissions for the
directories involved.  Hope it helps and makes it into the next release of
check_traffic..
