Create a Customized Live Linux CD or Bootable USB Thumb Drive Using Knoppix

Filed under
HowTos

Earlier this year, I was asked to find a bootable CD that would allow PCs in a special purpose lab, many of which had bad hard drives, to access our Citrix environment. Basically, we wanted to turn these PCs into thin clients to extend their life. I had been experimenting with Knoppix and decided it was time to try customizing my own Knoppix CD for use in the lab.

How can I change the default size of an inode when I create an ext2/ext3 filesystem?

Filed under
HowTos

It is possible to define a non-standard sized inode by using the mke2fs tool with an undocumented option, -I. The size of the inode has to be a power of two and between the size of EXT2_GOOD_OLD_INODE_SIZE (128 bytes) and size of blocks in bytes. One reason for doing this could be that user is going to use extended attributes.

Removing files from /tmp at shut down

Filed under
HowTos

Your /tmp directory in Linux is a handy place for your OS to stick files that it may need at the moment but won’t need down the road. While this is great for the OS (and you if you want to use it yourself feel free) it can cause a bit of clutter as files start building up.

Put your OpenSSH server in SSHjail

Filed under
HowTos

Jailing is a mechanism to virtually change a system's root directory. By employing this method, administrators can isolate services so that they cannot access the real filesystem structure. You should run unsecured and sensitive network services in a chroot jail, because if a hacker can break into a vulnerable service he could exploit your whole system.

Getting more out of less

Filed under
HowTos

Anyone who knows Linux and other similar operating systems like Unix and BSD should be familiar with the paging program called "more". They should also be familiar with its successor which offers much more functionality but is called "less". Less offers much more than simple forward and backward paging.

CuBox-i4Pro Review

A bundled microSD card arrives preinserted into the rear of the CuBox-i, and it’s loaded with a version of Google’s Android operating system. Interestingly, SolidRun has gone to the effort of seeking the certifications required to load the Google Apps suite onto the card, meaning users receive Google Mail, YouTube, Google Maps and full access to Google Play straight out of the box. An even newer build, based on the latest Android 4.4 KitKat branch, can be downloaded from SolidRun’s website and provides an entirely useable desktop Android experience. Read more

Working on 3.19 – the kernel column

Linus Torvalds announced the release of Linux kernel version 3.18 in time for the holidays. In his mail, Linus noted that the previous RC, release candidate 7, had been “tiny” (in terms of changes and bugfixes), so it was time to get the final release out. The latest kernel includes support for storing AMD Radeon GPU buffers in regular application memory (building upon similar work done by Intel for kernel 3.16), and overlayfs (which we have covered previously), amongst a number of other less interesting new features. A full summary is provided at Kernel Newbies. Read more

The top 10 rookie open source projects

Open source has become the industry's engine of innovation. This year, for example, growth in projects related to Docker containerization trumped every other rookie area -- and not coincidentally reflected the most exciting area of enterprise technology overall. At the very least, the projects described here provide a window on what the global open source developer community is thinking, which is fast becoming a good indicator of where we're headed.

First thoughts on KaOS 2014.12

The latest snapshot of this rolling release distribution includes initial support for UEFI, the KDE 4.14 desktop, systemd version 218 and the Qupzilla web browser. I mention Qupzilla because I feel it is a rare gem in the open source world, a quick capable browser that perhaps does not get the attention it deserves. KaOS is available in just one edition, a 64-bit x86 build. The ISO we download for KaOS is 1.6GB in size. Read more
