  • Redbooks Paper Linux on IBM Zseries and S/390
    Redbooks Paper Simon Williams Linux on IBM zSeries and S/390: TCP/IP Broadcast on z/VM Guest LAN Preface This Redpaper provides information to help readers plan for and exploit Internet Protocol (IP) broadcast support that was made available to z/VM Guest LAN environments with the introduction of the z/VM 4.3 Operating System. Using IP broadcast support, Linux guests can for the first time use DHCP to lease an IP address dynamically from a DHCP server in a z/VM Guest LAN environment. This frees the administrator from the previous method of having to hardcode an IP address for every Linux guest in the system. This new feature enables easier deployment and administration of large-scale Linux environments. Objectives The objectives of this paper are to: Review the z/VM Guest LAN environment Explain IP broadcast Introduce the Dynamic Host Configuration Protocol (DHCP) Explain how DHCP works in a z/VM Guest LAN Describe how to implement DHCP in a z/VM Guest LAN environment © Copyright IBM Corp. 2003. All rights reserved. ibm.com/redbooks 1 z/VM Guest LAN Attention: While broadcast support for z/VM Guest LANs was announced with the base z/VM 4.3 operating system, the user must apply the PTF for APAR VM63172. This APAR resolves several issues which have been found to inhibit the use of DHCP by Linux-based applications running over the z/VM Guest LAN (in simulated QDIO mode). Introduction Prior to z/VM 4.2, virtual connectivity options for connecting one or more virtual machines (VM guests) was limited to virtual channel-to-channel adapters (CTCA) and the Inter-User Communications Vehicle (IUCV) facility.

  • Firewalld ↔ Iptables (Continued)
    firewalld ↔ iptables (continued) Or, better said as, Understanding Linux Firewall Changes and Tools A firewall evolution and system management process Presented to SLUUG By David Forrest August 9, 2017 Bio I am David Forrest, a businessman in the housing and construction materials industry. Always keen to use the open and supportable solution even if it means getting my hands dirty. I was there, I did that, I have the t-shirt. And, I'm retired so now I can work on the “bleeding edge” - so on to the testing kernel! Why tonight? Why should we switch to firewalld? I felt a continuation was in order to address the problems that are caused by the virtual world and the interaction of processes within today's machines. Our various distributions seem to be jumping to the systemd init setup as it appears to offer better administration control to Linux Kernel machines. Firewalld just one of many efforts to see the future. In recent years, operating system virtualization has taken the industry by storm. But I'm still on CentOS7 and it uses firewalld as its default firewall along with systemd https://wiki.debian.org/Debate/initsystem/systemd firewalld It's a daemon and a command line interface to all the backends! One can start it as a service with a default setup and change it dynamically with a command line or with the daemon using D-Bus or NetworkManager. And with the new nftables release, we'll be able to combine several rules in one rich rule. The firewalld Architecture Firewalld and nft Systems have also moved toward Software Defined Networking (SDN) and system density has increased.

  • Building a Beowulf Cluster
    Building a Beowulf cluster Åsmund Ødegård April 4, 2001 1 Introduction The main part of the introduction is only contained in the slides for this session. Some of the acronyms and names in this paper may be unknown. In Appendix B we includ short descriptions for some of them. Most of this is taken from “whatis” [6] 2 Outline of the installation ² Install linux on a PC ² Configure the PC to act as a install–server for the cluster ² Wire up the network if that isn’t done already ² Install linux on the rest of the nodes ² Configure one PC, e.g the install–server, to be a server for your cluster. These are the main steps required to build a linux cluster, but each step can be done in many different ways. How you prefer to do it, depends mainly on personal taste, though. Therefor, I will translate the given outline into this list: ² Install Debian GNU/Linux on a PC ² Install and configure “FAI” on the PC ² Build the “FAI” boot–floppy ² Assemble hardware information, and finalize the “FAI” configuration ² Boot each node with the boot–floppy ² Install and configure a queue system and software for running parallel jobs on your cluster 3 Debian The choice of Linux distribution is most of all a matter of personal taste. I prefer the Debian distri- bution for various reasons. So, the first step in the cluster–building process is to pick one of the PCs as a install–server, and install Debian onto it, as follows: ² Make sure that the computer can boot from cdrom.

  • The Linux Device File-System
    The Linux Device File-System Richard Gooch EMC Corporation [email protected] Abstract 1 Introduction All Unix systems provide access to hardware via de- vice drivers. These drivers need to provide entry points for user-space applications and system tools to access the hardware. Following the \everything is a file” philosophy of Unix, these entry points are ex- posed in the file name-space, and are called \device The Device File-System (devfs) provides a power- special files” or \device nodes". ful new device management mechanism for Linux.

An alternative mechanism is then presented. It is an alternative to conventional disc-based char- acter and block special devices. Kernel device drivers can register devices by name rather than de- vice numbers, and these device entries will appear in the file-system automatically. 1.1 Device numbers Devfs provides an immediate benefit to system ad- ministrators, as it implements a device naming scheme which is more convenient for large systems Conventional Unix systems have the concept of a (providing a topology-based name-space) and small \device number".
