snmp_synch_response

[George, Geo]

Hi all, I am using NetSNMP version 5.0.9 for developing a sub agent on solaris.   The sub agent periodically needs to check the value (threshold) of a specific OID.  I have gone through the getsnmp code and followed the same approach. The problem is currently I am not able to get the community string, defined in snmp.conf. ( master configuration file) Tried using “netsnmp_ds_get_string(NETSNMP_DS_LIBRARY_ID,NETSNMP_DS_LIB_COMMUNITY); but it dumps core. The above function is called in init function of sub agent, which is called after - init_snmp() and init_agent() in main agent file. So the calling sequence is a) Init_agent() b) Init_snmp() c) Init_subagent() - -> GetOidVal()   Also is this the best way to get value for a specific OID from master agent?   Expecting a reply…   Thanks in advance, George     NB: Here is the code snippet. ========================================== GetOidVal() {     snmp_sess_init(&session);     char* comm_str = netsnmp_ds_get_string(NETSNMP_DS_LIBRARY_ID,NETSNMP_DS_LIB_COMMUNITY);     session.version = SNMP_VERSION_1;     session.community  = (unsigned char*) comm._str;     session.community_len = strlen( session.community );     session.peername = "localhost";     sess_handle = snmp_open(&session);       pdu = snmp_pdu_create(SNMP_MSG_GET);     snmp_add_null_var( pdu, chkOid, oid_len);       status = snmp_synch_response(sess_handle, pdu, &response);    if (response->variables) && response->errstat == SNMPERR_SUCCESS  && response->variables->val.integer)     read_value() }   ============================================
