Linux Forums
The Linux discussion forums are the place for developers, administrators, and users to ask questions, get answers, and share knowledge about the Linux operating system and related technologies. Whatever your hardware -- x86, Power-based, or mainframe -- the developerWorks Linux community welcomes you. Our discussion forums
work best when people follow these community guidelines.

Advance Toolchain for Linux on POWER
The Advance Toolchain is a collection of free-software application development products specifically tailored to make early use of IBM hardware features. It includes GCC (GNU Compiler Collection), GLIBC (GNU C Libraries), GNU binary utilities, GDB ( GNU debugger), and the performance analysis tools (QProfile and Valgrind) in a self contained Toochain. The Advance Toolchain duplicates the function of packages already delivered by Linux distributors but provides additional features for the POWER6 family of processors as indicated in the Advance Toolchain Release Notes 'Features' section.
The Advance Toolchain is built by and available from the University of Illinois at ftp://linuxpatch.ncsa.uiuc.edu/toolchain.

Chiphopper Tool Use
The Chiphopper offering has expanded access to its tools to include customers and non-participating ISVs. These tools can help maintain single source for C and C++ code on mutiple Linux platforms. They can be useful to run prior to doing a port to a new IBM system running Linux, or during a consolidation exercise onto a larger Linux system.The tools come from two sources -- the Linux Foundation as part of Linux Standard Base (LSB) certification for applications, and also from the IBM Chiphopper team. The LSB tools check for use of standard APIs, and the Chiphopper tool checks for coding to differences in hardware platforms that could cause portability problems. This forum is designed to help people using these tools exchange information about the tools and interpreting their output to achieve more efficient Linux portability. The external web site is http://www-128.ibm.com/developerworks/linux/chiphopper/

Energy Management for System x Blueprint Forum
Forum for discussions of and reporting issues related to the available IBM Energy Management Blueprints located on IBM's Information Center for Linux.
- The IBM Blueprint for monitoring and controlling power consumption on Linux describes how to monitor and control power use on System X servers that have the relevant hardware features--specifically, systems that support either Intel's Enhanced Speed Step (EIST) or AMD's PowerNow, and have power meter hardware installed.
- The CPUFreq Blueprint describes how to use the Linux CPUFreq subsystem on RHEL5.3 to exploit the processor performance state (P-state) feature that is commonly available to newer processors. This feature can be configured to statically alter the processor operating frequency or dynamically scale the frequency to the current processor usage, so that less power is consumed without performance loss.

IPMI Blueprint Community Forum
Forum for discussions and exchange of ideas related to the IPMI Linux Blueprint as presented on IBM's Information Center for Linux
This Linux blueprint introduces the Intelligent Platform Management Interface (IPMI) and key open community software, especially the OpenIPMI driver and the IPMItool utility that support it on Linux. IPMI is a standardized message-based hardware management interface. It provides a foundation for full monitoring and management, both locally and remotely in a secure manner. This paper shows you how to take advantage of the IPMI capability on SUSE Linux Enterprise Server (SLES) or Red Hat Enterprise Linux (RHEL) based Linux servers

Linux Security Community Forum
Community Forum for discussions and exchange of ideas related to the IBM Linux Security Blueprints posted on IBM's Information Center for Linux.
The Security Blueprint(s) are available for both RHEL 5.2 and SLES 10 SP2 running on System x and provide concrete advice on how to use encryption to protect data at rest and vastly improve an organization’s resistance to data leaks. These blueprints demonstrates step by step how to setup a new encrypted data partition, swap partition, temporary file system, and how to migrate your old data to a new encrypted partition.
The eCryptfs Blueprint discusses key management which is traditionally the weakest point in deployed data encryption mechanisms. This blueprint explains how to build and install the eCryptfs software along with its dependencies, how to set up encrypted swap, how to generate a TPM-sealed key, and how to perform the eCryptfs mount with the TPM-sealed key on Red Hat Enterprise Linux Version 5.2.
The MIT-Kerberos with IBM Tivoli Directory Server Blueprint describes, in detailed steps, the procedure to configure a Kerberos authentication Realm using MIT-Kerberos and Tivoli Directory Server (ITDS) V6.2 to store the authentication data.

IBM System p, AIX 5L and Linux Technical University 2006 Forum
The forum has been set up to allow a two way communication between the conference organizers and the conference attendees. In the run up to the conference we will be announcing late additions to the agenda and give attendees the opportunity to comment on the content of the event, possibly to suggest issues you would like to see specific presentations address and items you would like to see included in the Open Forum sessions. This forum does not replace the session evaluations you complete at the end of each session, but will act as a discussion area throughout the conference.
