The sysctl returns seconds, just what ipReasmTimeout is. --- contrib/bsnmp/snmp_mibII/mibII_ip.c | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) diff --git a/contrib/bsnmp/snmp_mibII/mibII_ip.c b/contrib/bsnmp/snmp_mibII/mibII_ip.c index 8290eebbc6f0..6a59a5b8e388 100644 --- a/contrib/bsnmp/snmp_mibII/mibII_ip.c +++ b/contrib/bsnmp/snmp_mibII/mibII_ip.c @@ -44,6 +44,7 @@ static struct icmpstat icmpstat; static int ip_forwarding; static int ip_defttl; +static u_int ip_fragttl; static uint64_t ip_tick; static uint64_t ipstat_tick; @@ -79,6 +80,17 @@ fetch_ipstat(void) return (-1); } + len = sizeof(ip_fragttl); + if (sysctlbyname("net.inet.ip.fragttl", &ip_fragttl, &len, + NULL, 0) == -1) { + syslog(LOG_ERR, "net.inet.ip.fragttl: %m"); + return (-1); + } + if (len != sizeof(ip_fragttl)) { + syslog(LOG_ERR, "net.inet.ip.fragttl: wrong size"); + return (-1); + } + ipstat_tick = get_ticks(); return (0); } @@ -309,7 +321,7 @@ op_ipstat(struct snmp_context *ctx __unused, struct snmp_value *value, break; case LEAF_ipReasmTimeout: - value->v.integer = IPFRAGTTL; + value->v.integer = ip_fragttl; break; case LEAF_ipReasmReqds:
