Bug Fix Advisory ntp bug fix update

Advisory: RHBA-2009:0125-6
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2009-01-20
Last updated on: 2009-01-20
Affected Products: Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux Desktop (v. 5 client)

Details

An updated ntp package that fixes various bugs is now available.

The Network Time Protocol (NTP) is used to synchronize a computer's time
with a referenced time source.

This updated package fixes the following bugs:

* on systems with two or more interfaces, ntpd selected the first
multicast-capable interface presented by the kernel, even if a "broadcast"
option in "/etc/ntp.conf" specified a different subnet (which would cause a
different interface to be used).

With this update, ntpd now finds and selects the default multicast
interface as mapped by the kernel, rather than automatically selecting the
first multicast-capable interface presented. As a consequence, if
"/etc/ntp.conf" specifies a different subnet, ntpd now selects the expected
multicast interface.

* when ntpd was started with the "-x" option, ntpd did not disable the
kernel time discipline. With this update, the "-x" option works as
documented in the ntpd(8) manual page.

Users of ntp are advised to upgrade to this updated package, which resolves
these issues.
