Introduction If you, like me have a linux only environment running on your system, you will run into upgrade issues once in a while. I recently found that I wanted to use the tpm chip on my laptop, a HP Probook 440 G3, to decrypt my luks partition in an automated way. And knowing that things will benefit me, from using the latest standard, it found that I should upgrade my tpm chip from 1....
When working with urxvt the ‘default’ way of working with the powerline font’s does not appear to be working. The work around is, installing a patched version of the font in your local home directory. This can be done using the following lines of code: cmd=$(pwd) tmp=$(mktemp -d) cd ${tmp} wget https://github.com/powerline/fonts/archive/master.zip unzip master.zip mv fonts-master/* ~/.local/share/fonts/ cd ${cmd} rm -r ${tmp} fc-cache -vf ~/.local/share/fonts And now, use the following line in your ~/....
Recently I switched DE (desktop environment) from Plasma to lxqt. The change itself is quite simple, it basically means executing: sudo apt install lubuntu-desktop Once the installation is complete, only an desktop environment is giving that is really limited in the way it is setup. The most annoyn thing for me was the fact that my keyboard sound (volume) buttons did not work. So I started looking on the internet what might be the cause for this....
During some experiments I wanted to check if it is possible to install java, using puppet. This turned out to be quite simple. All that was needed where 2 simple scripts. The first shell script simply installs the puppet and a depended puppet module. #!/bin/sh sudo apt-get install puppet sudo puppet module install puppetlabs/apt sudo puppet apply java.puppet The second file (called java.puppet) should be placed in the same directory and will update apt, accept the java license and install java7, and make it the default java version....
Recently I changed a Samba installation from using the ‘classic’ file based backend to a newer ldap based backend, in a production environment. Following one of the many guides in the internet helped a lot, for this task I used most information from: https://help.ubuntu.com/community/LDAPClientAuthentication & http://raerek.blogspot.hu/2012/05/samba-pdc-on-ubuntu-1204-using-ldap_28.html The biggest problem I faced was that one error showed up during domain login from a terminalserver which prevented roaming profiles to work. The error was:...
After a few days of hacking the source-code I am proud to provide you all with a shorewall6 module for webmin. This module (rev 1) is included in the main development stream of webmin. The current version (rev 2) has been submitted moments ago. The development takes place using webmin and can be found here https://github.com/woutervb/webmin. But obviously one can also wait for the next webmin release to appear or use the main development branch from webmin itself (https://github....
Updating a SSD firmware might seem like a big step on linux, as the biggest audience for the ssd manufacturers are windows users. This means that a lot of tooling and documentation is around on the internet explaining on how todo this on a windows based system. In the case of OCZ the tool used to update the firmware is linux based, or at least there is a linux based version available....
Some time ago I had to reinstall a deb based system, which meant installing the packages and configure them. During the configuration I had to rethink how the system was originally configured, without having a proper backup of the system. Some of issues where that the backup contained some configuration files, but files referenced where not included. To overcome this problem I started creating a small piece of code (and placed it on github) which implements the following idea:...
With Debian it is relative easy to setup ipv6 using aiccu. This can be done using the following steps (assuming you already have an account at www.sixxs.net): install aiccu sudo apt-get install aiccu edit de /etc/network/interfaces add the following entries: auto sixxs iface sixxs inet6 manual up ip link set mtu 1480 dev $IFACE pre-up invoke-rc.d aiccu start post-down invoke-rc.d aiccu stop disable the automatic start of aiccu sudo update-rc.d aiccu disable bring the interface up using the command...
Some people already found out the hard way that simply changing the /etc/fstab to make the root filesystem use the journal writeback modus will break the system. The trick to enable this feature is relative simple and involves 1 additional step to editing the /etc/fstab Lets use the below /etc/fstab snippet to illustrate the steps involved /dev/sda5 / defaults 0 0 We change this /etc/fstab snippet to: /dev/sda5 / data=writeback 0 0 And we execute the following command:...
