Ubuntu snmp Problems

Ubuntu 12.04 didn't install the MIB files. even if you install the SNMP applications. just check the preamble of/etc/snmp. conf # As the snmp packages come without MIB files due to license reasons, loading # of MIBs is disabled by default. if you added the MIBs you can reenable # loaging them by commenting out of the following line. mibs: Sure, but how can I install them? Fortunately there is a package to deal with that. $ sudo apt-get install snmp-mibs-downloader It will download the ietf mib files and install them under the usual/usr/share/mibs/If for any reason you don't see it happen force it with $ sudo download-mibs You can repeat this command later to update any new MIB file. test snmpwalk-v 2c-c public localhostUnlinked OID in IPATM-IPMC-MIB: marsMI after installation is complete B: = {mib-2 57} Undefined identifier: mib-2 near line 18 of/usr/share/mibs/ietf/IPATM-IPMC-MIBBad operator (INTEGER ): at line 73 in/usr/share/mibs/ietf/SNMPv2-PDUUndefined OBJECT-GROUP (diffServMIBMultiFieldClfrGroup ): at line 2195 in/usr/share/mibs/ietf/IPSEC-SPD-MIBUndefined OBJECT-GROUP (diffServMultiFieldClfrNextFree ): at line 2157 in/usr/share/mibs/ietf/IPSEC-SPD-MIBUndefined OBJECT-GRO UP (diffServMIBMultiFieldClfrGroup): At line 2062 in/usr/share/mibs/ietf/IPSEC-SPD-MIBExpected ": =" (RFC5644 ): at line 493 in/usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIBExpected "{" (EOF ): at line 651 in/usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIBBad object identifier: at line 651 in/usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIBBad parse of OBJECT-IDENTITY: At line 651 in/ Usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB solution :#! /Bin/bashfor I in/usr/share/mibs/ietf/IPSEC-SPD-MIB/usr/share/mibs/ietf/IPATM-IPMC-MIB/usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-MIB/usr/share /mibs/ietf/SNMPv2-PDUdomv $ I/usr/share/mibsdone another snmpwalk-v 2c-c public 192.168.1.1 mem can be used, snmpwalk-v 2c-c public 192.168.1.1 cpu is not available, because the cpu does not have this logical name, so you can directly use OID, snmpwalk-v 2c-c public 192.168.1.1. 1.3.6.1.2.1.25.3.3.1.2 snmpwalk-v 2c-c public 192.168.1.1. others-RESOURCES-MIB: Drivers = INTEGER: 1HOST-RESOURCES-MIB: Drivers = INTEGER: 0HOST-RESOURCES-MIB: Drivers = INTEGER: 0HOST-RESOURCES-MIB: Drivers = INTEGER: 1HOST-RESOURCES-MIB: Drivers = INTEGER: 0HOST-RESOURCES-MIB :: failed = INTEGER: 0HOST-RESOURCES-MIB: Success = INTEGER: 1HOST-RESOURCES-MIB: Success = INTEGER: 0HOST-RESOURCES-MIB: Success = INTEGER: 1HOST-RESOURCES-MIB: Success = INTEGER: 1HOST-RESOURCES-MIB: Success = INTEGER: 1HOST-RESOURCES-MIB: Physical = INTEGER: 2HOST-RESOURCES-MIB: Physical = INTEGER: 0HOST-RESOURCES-MIB: Physical = INTEGER: 1HOST-RESOURCES-MIB: Physical = INTEGER: 0HOST-RESOURCES-MIB: Physical = INTEGER: 0; simplified snmpd. conf ##### First, map the community name "public" into a "security name" # ec. name source community com2sec my_user 192.168.1.1 public #### Second, map the security name into a group name: # groupName securityModel securityName group my_group v2c my_user #### Third, create a view for us to let the group have rights to: # name incl/excl subtree mask (optional) view all supported ded. 1 80 ##### Finally, grant the group read-only access to the systemview view. # group context sec. model sec. level prefix read write notif access my_group "" any noauth exact all none #### Customer pass_persist. 1.3.6.1.3.1/usr/bin/perl/usr/local/bin/iostat-persist.pl
