>Description:
After upgrade to net-snmp 5.7 counter of TCP connections stopped working:
snmpget -c public -v2c xxx .1.3.6.1.2.1.6.9.0
TCP-MIB::tcpCurrEstab.0 = Gauge32: 0
The reason is this change in net-snmp source ./work/net-snmp-5.7/agent/mibgroup/mibII/tcp.c
#ifdef NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS
ret_value = TCP_Count_Connections();
#else /* NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS */
ret_value = 0;
#endif /* NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS */
The define NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS is not defined. After addition here:
#define NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS
#ifdef NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS
ret_value = TCP_Count_Connections();
#else /* NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS */
ret_value = 0;
#endif /* NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS */
counter works again:
snmpget -c public -v2c xxx .1.3.6.1.2.1.6.9.0
TCP-MIB::tcpCurrEstab.0 = Gauge32: 1094
>How-To-Repeat:
>Fix:
Delete #ifdef or #define NETSNMP_FEATURE_HAS_TCP_COUNT_CONNECTIONS in proper place.
