1NTP SNMP subagent for Net-SNMP 2 3Installation Guides: 4 5- install net-snmp from source (configure, make;, make install) 6- edit the snmpd configuration file (/usr/local/share/snmp/snmpd.conf): 7 add the lines 8 master agentx 9 agentXSocket tcp:localhost:705 10 and check which read-only community is configured (should be "rocommunity public") 11- start snmpd (sudo /usr/local/sbin/snmpd) and check that it is running correctly by running the command 12 snmpwalk -v2c -c public localhost 13 (which should output a lot of data values for the supported built-in MIBs of net-snmp) 14- build the libntpq and the libntp library 15- build the ntpsnmpd application (make) and run it (./ntpsnmpd) 16- now you can run 17 snmpwalk -v2c -c public localhost enterprises.5597.99 18 which should give you a list of all currently supported NTP MIB objects and their current values 19 20Please note that currently I use a private MIB OID (enterprises.5597 is the Meinberg top level OEM OID and 99 is my temporary working space for this project). 21The final OID has to be registered with IANA and this is done by the RFC Editor when the NTPv4 MIB RFC is standardized. 22I will try to do this earlier in order to be able to have a working solution at the end of this project. 23 24In its current state the daemon supports these objects: 25 26ntpEntSoftwareName 27ntpEntSoftwareVersion 28ntpEntSoftwareVersionVal 29ntpEntSoftwareVendor 30ntpEntSystemType 31ntpEntTimeResolution 32ntpEntTimeResolutionVal 33ntpEntTimePrecision 34ntpEntTimePrecisionVal 35ntpEntTimeDistance 36 37They all use the libntpq library to access information from the ntpd instance with mode 6 packets. 38 39Next step is to implement the status section of the MIB (section 2). 40 41
