  • rsync

    • A quick reminder to myself on rsync usage

    $ rsync -Cvrtp <source> <destination>
C = cvs-exclude
V = verbose
r = recursive
t = times
p = permissions
K = keep dir links

  • DNSmasq and Pi-hole

     May 8, 2016

    • For a long time I have been using bind as a LAN DNS server. Just for my local server setup, so that I can use hostnames instead of IP addresses. I found the hosts file to be a bit low-tech, and it was a good chance to learn a little about DNS along the way. :-)

    A short while ago I was watching the Linux Action Show, where the Pi-hole system was introduced. Now being able to block ads before they are even entering the network (or more correctly before they are requested) seems like a super idea to me. So I started reading up on the requirements.

  • Email server and iptables

     Dec 25, 2015

    • Ever notice how many braindead people try to break into your email server? It's a daily battle to stay ahead of them. Especially when, like in my case, fail2ban just... well... fails... :-)

    For some time I have just manually added IP addresses to my iptables array. The list gets kind of long after a while though. See the following for what I did. And then imagine a lot of these lines.

    iptables -A INPUT -s <ip>/<cidr> -p tcp -m tcp --dport 25 -j DROP

    If you have the possibility, please support them. They are fighting for you!

  • Change ip address from the command line

     Aug 29, 2015

    • In my work I have to connect to various equipment that uses different IP addresses in order to configure and monitor them. To make it easier for myself I have made a couple of script files so that I can change the IP address easily.

    The first step before we can create the script file is finding the network adapter name. Don't worry. All we need is included in the Windows system.

  • AUR packages

     Mar 21, 2015

    • After I bought a new printer I needed to install the printer driver for it. Unfortunately I could not make the package, that already existed in the aur, work on my PC.
    Therefor I took my other printer driver PKBUILD and changed it to install my new printer driver.

    Instead of uploading it to the aur and create a duplicate package (sort of), I decided to include my aur packages on my own homepage. They can conveniently be found on the downloads page.

    • Happy New Year everyone!

    It's almost time. Get together with your family and enjoy a relaxed evening.

  • Backup using rsync

     Nov 10, 2014

    • Making a backup is a must. And although doing it manually works, it is far from perfect. What if you are busy one week and can't run your backup?

    And then there is the question about what method to use. Do you go with a commercial solution? Or one of the free alternative systems?
    Why not go outside your comfort zone and use a standard tool?

    Well that's what I thought anyway...

    Let's first take a look at the actual script:

  • Change language on Windows 7 Home Premium

     Nov 1, 2014

    • Unfortunately Microsoft does not support changing the on-screen language on the "smaller" versions of their Windows operating system.

    Fortunately there exists a third party tool that can handle that. It's called vistalizator and can be found on here.

    There is a pretty good guide on how to use it too. I used it succesfully on a colleagues PC to install his native language.
