RHBA-2011:1405 - Bug Fix Advisory

Topic

Updated net-snmp packages that fix a bug are now available for Red Hat
Enterprise Linux 4.

Description

SNMP (Simple Network Management Protocol) is a protocol used for network
management. The Net-SNMP project includes various SNMP tools: an extensible
agent; an SNMP library; tools for requesting or setting information from SNMP
agents; tools for generating and handling SNMP traps; and a version of the
netstat command which uses SNMP. Additionally, the net-snmp package contains the
snmpd and snmptrapd daemons, as well as Net-SNMP documentation.

These updated net-snmp packages fix the following bug:

• The previous net-snmp update for Red Hat Enterprise Linux 4 enhanced the

transport layer of Net-SNMP applications and daemons to send SNMP responses from
the network interface from which the corresponding SNMP request was received.
However, the snmptrapd daemon was not properly updated with this feature and it
logged "UNKNOWN" as the source of all incoming SNMP trap messages to syslog
instead of to the proper remote agent address. This update fixes this regression
so that snmptrapd correctly logs remote agent addresses to syslog. (BZ#745431)

All users of net-snmp are advised to upgrade to these updated packages, which
resolve this issue.
