Erro no MRTG

estou com um problema no meu MRTG.
eu uso FreeBSD 5.4, e na hora de iniciar o mrtg aparce o seguinte erro:


Rateup WARNING: /usr/local/bin/rateup could not read the primary log file for eumesmo
Rateup WARNING: /usr/local/bin/rateup The backup log file for eumesmo was invalid as well
/usr/local/bin/rateup: Permission denied
Rateup ERROR: Can't open eumesmo.tmp for write
ERROR: Skipping webupdates because rateup did not return anything sensible
WARNING: rateup died from Signal 0
with Exit Value 1 when doing router 'eumesmo'
Signal was 0, Returncode was 1
