Updated net-snmp packages that resolve several issues are now available for Red Hat Enterprise Linux 6.
The net-snmp packages provide various libraries and tools for the Simple Network Management Protocol (SNMP), including an SNMP library, an extensible agent, tools for requesting or setting information from SNMP agents, tools for generating and handling SNMP traps, a version of the netstat command which uses SNMP, and a Tk/Perl MIB browser.
The SNMP daemon, snmpd, returned the incorrect value of either "0.1" or 1.3" for sysObjectID. This update fixes the value of this OID so that the correct value, which is "18.104.22.168.4.1.8072.3.2.10", is now returned.
Under certain conditions, and especially on networks with high traffic, snmpd wrote a lot of "c64 32 bit check failed" and "netsnmp_assert 1 == new_val->high failed" messages to the system log. Although these messages are harmless and not indicative of a serious error, they could potentially fill the system log quickly. This update suppresses these spurious messages in favor of more meaningful and specific error messages, which are written to the system log only once.
All users of net-snmp are advised to upgrade to these updated packages, which resolve these issues.
