Yum

Yum – Some Simplifying Tricks

If you are using a distro that is able to use YUM and you have a couple of systems, you can save lots of time by:-

  • Creating your own Yum Repository
  • Sharing the updates for one machine with the other.

This section describes how you can setup one machine and let others use the updates for themselves. It does not describe how to setup your own yum repository(that comes in another document)

So, I have 2 systems. The first called Trophy650 is my general server. It is [continued…]

Virtual Memory

Most modern OSes don’t treat the physical RAM as a single contiguous area, from address 00000000 to 1fffffff (say, on a 512MiB machine). Instead, they have hardware (the MMU, or Memory Management Unit) which maps physical RAM to a logical address space. This is used heavily by the operating system to move memory about, usually in 4K chunks called “pages”.

On systems with 32-bit address spaces, the total available address space is 4GiB. This space will be used sparsely, with different chunks of physical RAM mapped to different areas of the available logical address space. Each area of [continued…]

What happened

Lovely sunny day, so true to geekdom we sat indoors (besides, that was where the food was). One new LUGer (Kevin) who is probably going to visit the next bring-a-box meeting to get some stuff fixed or sorted [continued…]

DHC Pand DNS

DHCP and DNS for a Private Network

If you have more than a couple of machines and do have at least 1 permanently-connected server, I think you’ll find life easier if you use both DHCP and DNS provided from that server.

Here’s what I would do:

==== Pick an internal domain name. ==== If you have an existing domain name like example.com then you could use a subdomain of it such as ‘int.example.com’ for internal hosts, or if you don’t have one then you can make up an ‘impossible’ top-level domain such as localnet. I shall [continued…]

Netgear WG511 Wireless Card

Netgear WG511 installation notes

There are a number of versions of this card, which appear to use one of two chipsets: Intersil or Marvell Technologies; those with the Intersil chipset can be used with the Prism54 drivers, while those with the Marvell chipset require ndiswrapper with the Windows drivers.

Installation is easy, once you’ve identified which chipset your card uses. The most reliable way to do this is by using ‘lspci’, identification by visual markings can mislead you, causing hours of frustration — in particular, not all cards marked ‘v2’ and ‘Made in Taiwan’ use [continued…]

Radio And RealPlayer

After some searching around on the web I have completed this exercise, please note that my system is based upon Fedora Core 3 and therefore RPM based.

  • Make sure that openmotif21.rpm is installed – check ayo.freshrpms.net.
  • Download the Realplayer RPM from here [[RealPlayer10GOLD.rpm]]

  • Then install the package with rpm -ihv [[RealPlayer10GOLD]].rpm

  • Once this has been completed create a soft link with the following commands.

     ln -s /usr/local/RealPlayer/mozilla/nphelix.so /usr/local/firefox/plugins/nphelix.so ln -s /usr/local/RealPlayer/mozilla/nphelix.xpt /usr/local/firefox/components/nphelix.xpt

    Now close and restart firefox and log into Radio4.
