Platform: Slight Unix/Linux Bias

RH Directory Server

When

Speaker

Kevan Benson / Trevor Benson
Details

Red Hat Directory Server / CentOS Directory Server provides an easily administered and robust solution for entities needing an enterprise class LDAP system. With support for 4 way multi-master replication, easy integration into the Red Hat suite of systems, and comprehensive documentation, it’s a good choice for both deploying a new LDAP structure and migrating from an existing one.

Covered topics will include:
Implementing redundancy through multi-master replication
Configuring clients to connect to LDAP for single sign on
Using pGina to provide LDAP auth for windows
Using Samba to provide single sign on for windows through native windows client

After attending this talk a system administrator of moderate experience with windows and Linux should be able to implement single sign on for a small heterogeneous network with little effort.

BackupPC

Speaker

Details

This month at SoCoSA we'll be covering BackupPC, a popular and very full featured open source backup system. BackupPC supports backup through SMB, Tar/gz over SSH or NFS, or rsync. The killer feature of BackupPC is file pooling, which allows identical files from different backups, or even different systems, to take up only the space of a single file on the backup server. This allows moderately priced backup servers to vastly increase the number of system they can backup, the retention period of backups, or both.

Details

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.

Meeting: Cricket

When

Speaker

Don Forbes; System Administrator at Sonic.net
Details

Don will talk about cricket.

Cricket is a high performance, extremely flexible system for monitoring trends in time-series data. In other words: it makes lots of pretty graphs that make it easier to understand what’s been going on with your servers and/or network. It’s really good at getting data via SNMP, but if you can get some number out of something automatically you can get cricket to graph it.

Here’s an example graph; Sonoma State’s primary internet connection traffic over the past year:

Can you tell which week’s classes were in session?

Meeting: Ruby on Rails

Speaker

Rob Orsini, author of the Rails Cookbook
Details

Rob will give a 1 hour overview of Rails including server setup, admin issues and templating.

What is Ruby on Rails? "Rails is a full-stack framework for developing database-backed web applications according to the Model-View-Control pattern." What that means, basically, is that it lets programmers write applications without needing to worry too much about the boring details. Alternately, it's a a new, very popular way to create dynamic websites quickly and easily. Even if you're not a programmer you'll eventually want to deploy some cool new Rails application, and maybe even customize it a little for your site's needs.

Speaker

Luke S. Crawford and Neal K.
Details

Join Luke and Neal to hear about Xen, the exciting new technology that will make your life happier and more productive. (Don't believe anything they say to the contrary -- they're just old and cynical.)

Xen is a virtualization technology that offers nearly all the traditional advantages of virtualization with near-native speeds. Using Xen, administrators can partition users into separate virtual machines, developers can rapidly test network applications, home users can enjoy robust checkpoints and configuration management. Right now it's all hackerware, but the revolution is coming.

Meeting: System Recovery with Knoppix

2006/09/06 - 8:30pm


Food at 6pm; talk starts at 7pm.

Knoppix is a complete Linux distribution that runs directly from CD. One of its most popular uses is as a rescue and recovery CD since it includes a wide range of incredibly flexible tools to fix a computer that won’t boot.

In this talk Kyle will discuss a number of different system recovery scenarios and how to use Knoppix (or another live CD) to restore both Linux and Windows systems. Among the recovery scenarios, Kyle will cover:


  • Restoring the Linux boot loader

  • Recreating the partition table from scratch
