Exclamation snmp-mrtg


hi, all my friends out there.
I am trying to set up mrtg.
i am using Red HAT 9. this pc is in my local lan with local ip 192.168.1.65.
it is behind a proxy.
i am using one linux box to act as proxy router . using iptables and natting.

i installed net-snmp
net-snmp-5.0.6-17
and net-snmp-utils
also
mrtg-2.9.17-13

and it works fine with my local system
when i type
#snmpwalk -v 1 -c SECRETKEY localhost system

i copied EXAMPLE.conf /usr/local/share/snmp/snmpd.conf
and added these
com2sec local localhost SECRETKEY
com2sec mynetwork NETWORK/24 SECRETKEY

when i run this
#env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

(or)
#indexmaker --output=/var/www/mrtg/index.html /etc/mrtg/x.x.x.x.cfg
this is the same error as given below.

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.
