I have been trying to pull snr data from a cisco 887 router.  I got a base
cfg from the web and changed what I think is correct but when I run it I
get the following error.  Prob a really silly thing but im just not seeing

env LANG=C /usr/bin/mrtg /etc/mrtg/test.cfg

The cfg is below.  I first thought it was the name in the [ ] so tried
