Hi Bob,
Im sorry, I was a bit "nerdy" in my reply regarding adding stuff.
Mandriva is an rpm-based distro, that means that software you want to
install, uninstall and upgrade come precompiled and packaged in rpm-
files. These files contain the "exe"-file and any other unique stuff
needed for the application. It may also have a list of dependencies such
as libraries that it will need to use. For instance the gmfsk package
wants the hamlib rpm to be installed and if you try to install gmfsk prior
to installing hamlib then it will stop and warn about missing
dependencies.
These missing dependencies was the start of the frustrating experience
called "rpm-hell". That happens when my rpm wants another that in turn
wants two more that... Well, you get the picture.
urpmi is a tool that helps with these installs. You give it url's to the
distributions repositories/mirrors and when you try to install something
it will fetch necessary dependencies for you. If I once again try to
install something that has unsatisfied dependencies, then it will ask "Do
you want me to fetch these....necessary dependencies for you"... If you
want that then it will fetch and install the dependencies and then the
package you wanted. You can also install stuff from the mirrors without
downloading anything manually, for instance just type "urpmi dia" and it
will fetch and install the dia application for you.
There are similar tools for other distros, apt-get is one and yum is
another. They all work something along these lines. The good thing about
mandriva here is the absolutely huge repository of packages, bigger than
what any other distro has.
The site at http://www.urpmi.org contain a helper script to make is easy
to configure urpmi. Using that script you can select what mirrors urpmi
should be able to fetch packages from. Main is the mirror containing the
stuff distributed on cd and dvd, contrib contains all of those that is
very useful but didn't fit on the DVD. PLF is the "Penguin Liberation
Front" and that contains stuff that Mandriva refuses to distribute. Among
other things are codecs for watching video and listen to wma-coded files.
Video rippers, p2p-stuff and all sorts of "necessary" files ;-).
Regarding psk125 I had that running on the server during the night. When I
checked the server this morning it was extremly slow and almost didn't
respond. When I killed fldigi it responded as it should agn. So, fldigi is
a very nice application but it may have a memory leak, will test some
more.
I also want to wait a while before I become a grandfather as well, our
youngest daughter has her first birthday in december and our kid Anton is
4 years old. I'd like to wait twenty years at least ;-)
I'm looking at thinkpads on a local auction site here now so what you
wrote on the wiki may help me too soon, thanks.
