RHBA-2011:0469 - Bug Fix Advisory

Topic

An updated traceroute package that fixes two bugs is now available for Red Hat
Enterprise Linux 5.

Description

The traceroute utility displays the route used by IP packets on their way to a
specified network (or Internet) host. Traceroute displays the IP address and
hostname (if possible) of the machines along the route taken by the packets.

This update fixes the following bugs:

• Prior to this update, using the "-m" command line option to specify the

maximum time-to-live (TTL) value in the range 1 to 5 caused the traceroute
utility to fail with the following error:

sim hops out of range

This update applies an upstream patch to ensure that all TTL values in the range
from 1 to 255 are supported as expected. (BZ#461278)

• Previously, using the "-l" command line option to specify the flow label of

the probing packets caused the utility to fail with the following error:

setsockopt IPV6_FLOWLABEL_MGR: Operation not permitted

With this update, the underlying source code has been modified to address this
issue, and using the "-l" option no longer causes traceroute to fail.
(BZ#644297)

All users of traceroute are advised to upgrade to this updated package, which
fixes these bugs.

Solution

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

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