Logwatch for Linux Systems.

2010-06-02 2 min read Fedora Linux

On my personal <a class="zem_slink freebase/en/client" title="Client (computing)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Client_%28computing%29">desktop at home, I like to see the <a class="zem_slink freebase/en/statistics" title="Statistics" rel="wikipedia" href="http://en.wikipedia.org/wiki/Statistics">statistics at least once a day, for what was installed, what was run with <a class="zem_slink freebase/en/sudo" title="Sudo" rel="homepage" href="http://www.sudo.ws/">sudo and other such details like <a class="zem_slink freebase/en/kernel" title="Kernel (computing)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Kernel_%28computing%29">kernel errors.

Running this monotonously every day is quite boring, so comes to rescue is logwatch. I have <a class="zem_slink freebase/en/fedora" title="Fedora" rel="homepage" href="http://fedoraproject.org/">Fedora <a class="zem_slink freebase/en/installation" title="Installation (computer programs)" rel="wikipedia" href="http://en.wikipedia.org/wiki/Installation_%28computer_programs%29">installation so I will talk about the location with respect to that so for your distribution it might be a little different.

There are a lot of reasons to customize your own Linux kernel: better performance, bugfixes, try out new features, and earn valuable geekcreds. In this new series Akkana Peck introduces us to the fundamental steps of building a Linux kernel.

kernel source code — the easier way to get it with git.

2010-02-04 1 min read Fedora

The simplest way to get the kernel code is :

git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

If you want to get the other branches then head over to <a href="http://git.kernel.org">”Kernel Git Page”

This will get the Linux kernel tree. As of today , 12 days ago, the tree was tagged to 2.6.31.

Now thats cool, but do you want it to be simpler and do not want to know the git command get to what you want to do that is learn linux kernel then here\’s what you can do :

sudo yum install teamgit

Here is the interface that you will get to add new repo:

Short Information about loaded kernel modules

2010-01-24 2 min read Linux

There are couple of ways you can find the information on the <a class="zem_slink" title="Loadable kernel module" rel="wikipedia" href="http://en.wikipedia.org/wiki/Loadable_kernel_module">loadable kernel modules. All these would always involve calling <a class="zem_slink" title="Lsmod" rel="wikipedia" href="http://en.wikipedia.org/wiki/Lsmod">lsmod to get the loaded kernel modules and then calling modinfo to get the info on the loaded modules. I will show you with examples:

$ lsmod
Module                  Size Used by
cdc_acm                19616 0
vfat                    8744 9
fat                    41836 1 vfat

Get list of git repositories from command line.

2009-10-04 3 min read Linux

Earlier I had posted a small blog on teamgit. The problem still is that you have to manually go to the git.kernel.org page and get the list of the repo’s that you can download. How about a command line to get the same. Here’s one:

wget -O – http://git.kernel.org |grep ”class=.list.” |grep -v title|awk -F’>’ '{print $3}’|sed ’s/<\/a//’

Output will be like this:<div id="_mcePaste" style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;">linux/kernel/git/ghaskins/linux-2.6-hacks.git
