RedHat9的service named stop問題及解決辦法(轉)[@more@]

原始的RedHat9(kernel-2.4.20-8)在單處理器系統上執行：

service named stop

之後，會出現無法清理named程式的問題，rndc呼叫也會失敗(日誌會有顯示)。

解決辦法：

推薦辦法：用up2date執行全部的系統更新。

臨時辦法：僅升級核心至2.4.20-9(當前最新2.4.20-20.9)。

Synopsis

Updated 2.4 kernel fixes USB storage

Issued: 2003-04-08

Updated: 2003-04-08

Topic

Updated kernel packages for Red Hat Linux 9 are now available.

The kernel package version 2.4.20-6 has a security hole in ptrace.

Using USB CD-ROMs on some ServerWorks systems can hang older versions

of the kernel.

Description

The Linux kernel handles the basic functions of the operating system.

A vulnerability in ptrace handling has been found in version 2.4.20-6

of the kernel. This vulnerability makes it possible for local users to

gain elevated (root) privileges without authorization. This vulnerability

is fixed in kernel-2.4.20-8 and kernel-2.4.20-9.

Please note this vulnerability only affects Red Hat Linux 9 boxed sets

manufactured for distribution within the United States. The part numbers,

which can be found on the bottom flap of the box, are RHF0120US and

RHF0121US. Copies of Red Hat Linux 9 obtained through other means (such as

from Red Hat Network, FTP, or international boxed sets) already contain

kernel-2.4.20-8 and are therefore not vulnerable to this issue.

An NPTL support defect in the kernel causes bind not to restart on

uniprocessor systems; this bug has been fixed in kernel-2.4.20-9.

USB mass storage devices (in particular, USB CD-ROMs) and the ohci driver

sometimes causes system hangs; this defect has been fixed.

Additionally, support for the tg3, e100, and e1000 drivers has been added.
