Description Jan Safranek 2007-07-16 09:52:46 UTC
+++ This bug was initially created as a clone of Bug #248196 +++

$ rpm -q net-snmp
net-snmp-5.1.2-11.EL4.7

and I get:
snmpwalk -v1 -c public localhost  .1.3.6.1.2.1.6

TCP-MIB::tcpRtoAlgorithm.0 = INTEGER: other(1)
TCP-MIB::tcpRtoMin.0 = INTEGER: 200 milliseconds
TCP-MIB::tcpRtoMax.0 = INTEGER: 120000 milliseconds
TCP-MIB::tcpMaxConn.0 = INTEGER: -1
TCP-MIB::tcpActiveOpens.0 = Counter32: 3261918
TCP-MIB::tcpPassiveOpens.0 = Counter32: 621191
TCP-MIB::tcpAttemptFails.0 = Counter32: 2433
TCP-MIB::tcpEstabResets.0 = Counter32: 480959
TCP-MIB::tcpCurrEstab.0 = Gauge32: 25
TCP-MIB::tcpInSegs.0 = Counter32: 112145954
TCP-MIB::tcpOutSegs.0 = Counter32: 114675625
TCP-MIB::tcpRetransSegs.0 = Counter32: 93175

Now I upgrade:

$ rpm -q net-snmp
net-snmp-5.1.2-11.EL4.10

and I only  get

TCP-MIB::tcpInErrs.0 = Counter32: 0
TCP-MIB::tcpOutRsts.0 = Counter32: 2049678

Note: I've removed the tcpConn table stuff.

This is on a 32-bit system, if that matters

-- Additional comment from jsafrane on 2007-07-16 05:29 EST --
It seems to me that net-snmp-5.1.2-11.EL4.10 got some fixes from upstream
breaking the OID comparsions, causing the 'getnext' requests to skip some TCP
scalars. I have patch prepared. In the meantime, you can use snmpget to get the
values you need:

snmpget -v1 -c public localhost  TCP-MIB::tcpRtoAlgorithm.0
TCP-MIB::tcpRtoAlgorithm.0 = INTEGER: other(1)
