    Maybe you’ve heard of ARP, netmasks or routing tables but aren’t quite sure what they are. Perhaps you know what a firewall does but aren’t sure how to set one up in Linux. Those and many more questions are answered in this entry-level course on networking. When you’re done you’ll be ready to go forth and network the world. Or your apartment, at least.

    Topics we cover:

    * Protocols: IP, ARP, TCP, UDP, ICMP, DNS
    * OSI 7 layer model, IETF we-don’t-need-no-stinkin’-models model
    * IP addresses (IPv4, touching on IPv6)
    * Networking commands in Linux
    * Firewall principles, with examples for Linux
    * Routing. What makes a router a router anyway?

    Corey has been a Network and Systems Engineer at a Wyoming ISP for the last 5 years, and as such gets to use all sorts of fun network and server tools. Outside of the lab he’s interested in hiking, cooking, gardening and photography.

  • Video: Josh Tolley at UTOSC 2009 – Fun With SQL

    By fozzmoo

    Add a comment

    Most developers find database interaction painful at some level; many dread it outright. What developer hasn’t spent hours digging through documentation, Google, or the nearest colleague, trying to work out how to write a particular query, only to find out two days too late that some obscure syntax would have made it easy? This talk aims to introduce the attendee to SQL idioms and constructs that can save weeks of debugging, free up hours of coding, and shave precious minutes and seconds from application runtimes.

    Josh Tolley participates actively in the PostgreSQL project and works as a PostgreSQL administrator for hire with End Point Corporation. On the rare occasions that the Utah Database Users Group, or UDBUG, happens to do anything, he’s likely somewhat responsible for it. He also enjoys gardening, cooking, and trying to learn electronics without hurting himself.

  • Audio: UTOSC 2009 – iSCSI for Fun and Profit by Aaron Burgemeister

    By herlo

    Add a comment

    Part of any business, whether using proprietary technologies or those that are Open, is keeping costs down. Clustering in environments share shared disk storage or network-enabled disk storage is required can make this tricky due to the expense associated with Fibre Channel. iSCSI is a technology that has been around for quite some time and which is free to use. The purpose of this presentation will be to show the steps involved in creating a shared storage environment using nothing but Linux (SUSE in my case) and commodity, Ethernet-enabled machines.

  • Audio: Provo Linux User Group May 2009 Meeting – The Open Source Data Center

    By herlo

    Add a comment

    During the last 10 years of system administration I have been involved in a number of data center migrations and build-outs. As these projects came and went I began to see patterns emerge in the set of services and software required to run a successful operations infrastructure. This presentation will describe these patterns, and provide an overview of the Open Source software available to implement them.

    The presentation was on partitions, filesystems, LVM and RAID by Aaron Toponce.

    The focus of my topic will by system administration, rather than for new beginners to the distribution.  It will be benificial for them as well learn how to properly work with their filesystems.
