[mrtg] snmpget problems

[Stuart Clark]

Hi

I had a squid box on Redhat 7.3 and MRTG was working well using snmp on
port 3104 from another box

I reinstalled squid on a new box with redhat 9 and used all the usual
squid settings to enable snmp.

acl snmppublic snmp_community public
snmp_port 3104
acl mrtg src 203.166.53.7/255.255.255.255
snmp_access allow snmppublic mrtg
snmp_incoming_address 0.0.0.0
snmp_outgoing_address 255.255.255.0


Now its broken!

But unexplainable are the clues. Can you help please

I have upgraded the new mibs.txt

I have the line LoadMIBs: /var/www/html/mrtg/scripts/mib.txt in my
mrtg.cfg


MRTG BOX - 203.166.53.7
SQUID BOX - 203.166.53.4

IT WORKS ON THE MRTG BOX USING SHELL

[root at mrtg mrtg]# snmpget -v 1 -c public -m 
var/www/html/mrtg/scripts/mib.txt 203.166.53.4:3104 cacheSysVMsize
SQUID-MIB::cacheSysVMsize = INTEGER: 65500


[root at mrtg mrtg]# snmpget -v 1 -c public -m
/var/www/html/mrtg/scripts/mib.txt 203.166.53.4:3104 cacheSysVMsize
SQUID-MIB::cacheSysVMsize = INTEGER: 65528


BUT FAILS ON MRTG BOX USING MRTG (snmp_util.pm)


[root at mrtg mrtg]# /usr/bin/mrtg  /var/www/html/mrtg/mrtg.cfg
