Dear net-snmp-coders,
I noticed there was a discussion on SNMP-COMMUNITY-MIB implementation among Dana Burns, Magnus Fromreide, Dave Shield, etc in Nov. 2006. Is there any progress since then? If not, I have implemented snmpCommunityTable(see the attached zip file). I would like to contribute to net-snmp-coders and seek your feedbacks on what is the best solution to integrate SNMP-COMMUNITY-MIB support into 5.3.1. My goal at first is to minimize the integration changes in VACM and snmplib, currently I only have one change in vacm_conf.c(see the attached patch file) and no changes in snmplib. Here is in summary what I did: 1. Created "snmpCommunity" directive to support snmpCommunityTable, this new directive uses the same syntax as "com2sec". 2. Added parse snmpCommunity function snmpCommunityTable_parse_snmpCommunity. 3. Added a new data struct snmpCommunityList to store snmpCommunityTable entries, creation/deletion of the entries via snmpCommunityStatus are supported. 4. Replaced netsnmp_udp_getSecName in vacm_conf.c with snmpCommunityTable_get_snmpCommunity. Limitations: The UDP6/UNIX _getSecName replacement are not implemented yet, but I think they could be done by calling UDP6/UNIX _getsnmpCommunity functions from vacm_conf.c in the same way as I have done with UDP. Plesae let me know if the snmpCommunityTable implementation is acceptable, I welcome any feedbacks.
