RHBA-2011:1524 - Bug Fix Advisory

Topic

Updated net-snmp packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

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 management information base (MIB) browser.

These updated net-snmp packages include numerous bug fixes. Space precludes
documenting all of these changes in this advisory. Users are directed to the Red
Hat Enterprise Linux 6.2 Technical Notes for information on the most significant
of these changes:

All users of net-snmp are advised to upgrade to these updated packages, which
provide numerous bug fixes.
