NetApp internals – how to add SSH keys without C$ nor NFS shares

This post will describe the process of placing SSH keys using the internal ‘systemshell’ command of NetApp. As always – when doing something which the vendor did not intend you to do, do it very carefully. This data was obtained from NetApp forums, and while I do not have the original post to link (I usually link to the original, as a courtesy to the original author), this is the content, as is.

Moving rsyslog stable to v8...

I am happy to tell that I have finally finished the 8.2.0 rsyslog release and it is on its way to announcement, package build and so on. While v8 was basically finished since before last christmas, we had a couple of mostly nits holding the release. This is probably a lesson that we need to accept some nits instead of holding a release for so long.

Python psutil – install recent version in Ubuntu

psutil/_psutil_linux.c fatal error: Python.h: No such file or directory

Recently while trying to install recent version of psutil I got following error:
psutil/_psutil_linux.c:12:20: fatal error: Python.h: No such file or directory
compilation terminated.
After debugging about the issue for a while I got to know that to install psutil recent version, it required python-dev module pre installed.
Use following command to install python-dev
$ sudo apt-get install python-dev
After installing python-dev psutil got installed without any issue.

Virtualization on ARM with Xen

This is a repost of a tutorial published initially on community.arm.com – Thank you to Andrew Wafaa for allowing us to repost.

With ARM entering the server space, a key technology in play in this segment is Virtualization. Virtualization is not a tool solely for servers and the data center, it is also used in the embedded space in segments like automotive and it is also starting to be used in mobile.

Increase font size of virtual terminals

My earlier post shows how to change, on the fly, the font size of X terminal emulators. Besides terminal emulators, Linux provides six virtual terminals which you can bring up from X Window by pressing Control+Alt+F1 to Control+Alt+F6 keys respectively. This post explains how to adjust the font size of virtual terminals for Debian, Ubuntu, and their derivatives.
