RHBA-2012:1449 - Bug Fix Advisory

Topic

Updated mrtg packages that fix three bugs are now available for Red Hat
Enterprise Linux 6.

Description

The mrtg packages provide the Multi Router Traffic Grapher (MRTG) to monitor the
traffic load on network-links. MRTG generates HTML pages containing Portable
Network Graphics (PNG) images, which provide a live, visual representation of
this traffic.

This update fixes the following bug:

• Prior to this update, the MRTG tool did not handle the socket6 correctly. As a

consequence, MRTG reported errors when run on a system with an IPv6 network
interface due to a socket conflict. This update modifies the underlying code to
socket6 as expected. (#706519)

• Prior to this update, changing the "kMG" keyword in the MRTG configuration

could cause the labels on the y-axis to overlap the main area of the generated
chart. With this update, an upstream patch has been applied to address this
issue, and changing the "kMG" keyword in the configuration no longer leads to
the incorrect rendering of the resulting charts. (BZ#707188)

• Prior to this update, the wrong value was returned from the IBM Fibrechannel

switch when using the ifSpeed interface. As a consequence, mrtg cfgmaker failed
to use ifHighSpeed on IBM FibreChannel switches. This update modifies the
underlying code to return the correct value. (BZ#836197)

All users of mrtg are advised to upgrade to these updated packages, which fix
these bugs.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
