Hi,
Did the update overwrite your snmpd.conf file? The 'view' on the default one may not permit access to the things mrtg needs to see. Try changing it to .1 to expose everything.
It might have done so. To be honest I have no idea since I've never touched the SNMP configuration before this and simply used the default. Currently there's nothing inside the snmpd.conf except a rocommunity which is the public user.
I've added lines from an online source that claims that is the default snmpd configuration and it looks like it should be allowing view all to the public user. In any case, even prior to adding these lines, I could get the relevant values off SNMP using command line with the public community user, so I don't think I was blocking any thing in SNMP
----------------------- snmpd.conf ------------------ #existing line rocommunity public localhost
#added by me com2sec public default public group public v1 public group public v2c public group public usm public view all included .1 access public "" any noauth exact all none none ------------------------ end ----------------------------
As expected, MRTG behaviour remains unchanged. In fact, looking at the mrtg log, with the default blank mrtg.cfg it does not even appear to be trying to poll SNMP. This is because if I added the target lines myself, MRTG would at least scream at me if SNMP does not return values or cannot find the variable name.
