I've just recently installed mrtg and snmpd from the Debian packages and had some trouble with configuration. With the default install, I was only able to view very basic information from snmpd -- No interface stats were displayed. After some careful examination of the snmpd.conf file (and several hours of sleep ;)), I found my problem. The default Debian snmpd only allows read-only access to some very basic system information. I changed these portions: Original: # sec.name source community com2sec paranoid default public #com2sec readonly default public #com2sec readwrite default private Changed: # sec.name source community #com2sec paranoid default public com2sec readonly 127.0.0.1 public #com2sec readwrite default private I'm only allowing connections from 127.0.0.1 (mrtg is running on the same box). Unchanged: #### # Second, map the security names into group names: # sec.model sec.name group MyROSystem v1 paranoid group MyROSystem v2c paranoid group MyROSystem usm paranoid group MyROGroup v1 readonly group MyROGroup v2c readonly group MyROGroup usm readonly group MyRWGroup v1 readwrite group MyRWGroup v2c readwrite group MyRWGroup usm readwrite #### # Third, create a view for us to let the groups have rights to: # incl/excl subtree mask view all included .1 80 view system included .iso.org.dod.internet.mgmt.mib-2.system #### # Finally, grant the 2 groups access to the 1 view with different # write permissions: # context sec.model sec.level match read write notif access MyROSystem "" any noauth exact system none none access MyROGroup "" any noauth exact all none none access MyRWGroup "" any noauth exact all all none ...As you can see, The MyROSystem (paranoid security name) would only allow read access to the .iso.org.dod.internet.mgmt.mib-2.system area of information...This is not enough for MRTG. However, MyROGroup allows access to all snmpd stats. I think this is all correct -- I'm by no means an snmpd expert. ;)
