LIO -fb in Debian

LIO -fb is the new SCSI Target for Debian. Previously, we maintained the LIO tools from the pre-fork upstream branch. But, with good reasons, we’ve now moved to the newer -fb (Free Branch). As the maintainer for those pacakges, I have a local LIO setup. Overy the years, I’ve been tuning and using this setup with a bunch of SCSI clients. Now with the new -fb packages it was worrisome for me, on how to migrate (Note: migration is not supported by the Debian packages) my old setup to the new one. [Read More]

SAN Updates for Debian Stretch

Now that we prepare for the next Debian Stable release (Stretch), it is time to provide some updates on what the current state of some of the (storage related) packages in Debian is. This is not an update on the complete list of packages related to storage, but it does cover some of them. REMOVALS iscsitarget - The iscsitarget stood as a great SCSI target for the Linux kernel. It seems to have had a good user base not just in Linux but also with VMWare users. [Read More]

apt-offline 1.7.2 released

I am happy to announce the release of apt-offline 1.7.2. This has turned out in time for the next release of Debian, i.e. Debian Stretch. A long standing cosmetic issue in CLI of the progress bar total item count has been fixed. There are also a bunch of other bug fixes, for which the specifics are present in the git logs. Also, in this release, we’ve tried to catch-up on the Graphical Interface, adding the GUI equivalent of the features, that were added to apt-offline in the recent past. [Read More]

GNOME Shell Extensions and Chromium

Most GNOME users may be using one or more extensions for the GNOME Shell. These extensions allow extending functionality for the shell, or modify default behavior, to suit the taste of many users, who may want more than the default. Having flexibility to customize the desktop to ones personal need is a great feature, and the extensions help achieve them. The GNOME Shell Extensions distribution mechanism is primarily through the web. [Read More]

User Mode Linux

Recently, we had the User-Mode Linux suite out of Debian, which included user- mode-linux, user-mode-linux-doc and uml-utilities package. We are happy that we were able to bring it back into the archvie quick, and hope to maintain it active. For many who may not know about UML, here’s a discription from its website: User-Mode Linux is a safe, secure way of running Linux versions and Linux processes. Run buggy software, experiment with new Linux kernels or distributions, and poke around in the internals of Linux, all without risking your main Linux setup. [Read More]

Fully SSL for my website

I finally made full switch to SSL for my website. Thanks to this simple howto on Let’s Encrypt. I had to use the upstream git repo though. The Debian packaged tool,, did not have enough documentation/pointers in place. And finally, thanks to the Let’s Encrypt project as a whole.

PS: http is now redirected to https. I hope nothing really breaks externally.

Linux Power Savings 2016

Having moved to a new place, now at times, I also have to deal with power outages. As heat increases, the power outages will be much longer and more frequent. So much, that UPS and Power Inverters run out. Such are ideal times to measure idle power consumption for my laptop. Here’s what my default (and idle) OS looks like. It should be standard to most “typical” users. Some minor odds could be apport, dnsmasq, and maybe, tor. [Read More]

Linux IO + Memory + CPU Contention

I very recently met someone, and we had a good productive discussion on the features and (long standing) bugs of the Linux kernel. No doubt, Linux is the most featureful kernel in the market. Is also a lot appealing given its breadth of platform support. Of that discussion we had, it led about Linux’s behavior in tighter stressed scenarios where there is a lot of contention among the core subsystems. From the conversation, I got the feedback that perhaps the issue is no more valid. [Read More]
