[mrtg] Won't work after reboot

[Aizad Fauzi]

Hi Steve,

Followed you advise and it works! But there is an additional step that I
took which is restarting snmpd.
1) rm -f mrtg.ok
2) /etc/init.d/snmpd restart
3) mrtg /path/to/mrtg.conf

without any error. are there any workaround on this if the router reboot by
itself? I am sorry as I am kinda newbie with unix.
