      1 NTP SNMP subagent for Net-SNMP
      2 
      3 Installation 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   
     20 Please 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). 
     21 The final OID has to be registered with IANA and this is done by the RFC Editor when the NTPv4 MIB RFC is standardized. 
     22 I will try to do this earlier in order to be able to have a working solution at the end of this project.
     23 
     24 In its current state the daemon supports these objects:
     25 
     26 ntpEntSoftwareName
     27 ntpEntSoftwareVersion
     28 ntpEntSoftwareVersionVal
     29 ntpEntSoftwareVendor
     30 ntpEntSystemType
     31 ntpEntTimeResolution
     32 ntpEntTimeResolutionVal
     33 ntpEntTimePrecision
     34 ntpEntTimePrecisionVal
     35 ntpEntTimeDistance
     36 
     37 They all use the libntpq library to access information from the ntpd instance with mode 6 packets.
     38 
     39 Next step is to implement the status section of the MIB (section 2).
