CentOS – find packages provided by repositories

CentOS, how-to

A quick note to myself… This is what I do when I need to find which packages are provided by a certain repository. First I update the list of the available packages:

# yum check-update

Then I do a listing of them (bold is mine):

# yum repolist
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
* base:
* epel:
* extras:
* updates:
Excluding Packages from CentOS-5 - Base
Excluding Packages from CentOS-5 - Updates
repo id repo name status
base CentOS-5 - Base 3,612+29
epel Extra Packages for Enterprise Linux 5 - x86_64 7,241
extras CentOS-5 - Extras 266
updates CentOS-5 - Updates 95
repolist: 11,214

At this point, if I need to find what packages are provided by the EPEL repository and write that list on a file, I’ll simply digit:

# rpm -qa | grep epel > epel-list.txt


how-to, OSX, Software

 If you – like me – work everyday on an OS X box with the opened over many remote servers, doing some sysadmin and frequently dealing with files management over & between those remote file systems, you could get some use of the benefits of FUSE technology and it’s porting on the Mac side.

In this way it’s easy as eating a pie to manage files on a remote server, on which we have made access via SSH, thanks to the SSHFS kernel module. We will see those file as a regular shared directory in our LAN with Finder. The easiest way to achieve this is by following this nice how-to published by the Computer Science Department of the University of Oregon:

builing a website for a workshop / meeting

deploy, how-to, ITB CNR

So, nearly a month ago I’ve deployed online with the COST Workshop Barcelona 2013 event website, prepared in a fast-and-furious mode since deadline was approaching and the number of things to do for the committee where overwhelming, so they’ve asked me to help.

To realize that I’ve relied on an old friend of mine, WordPress, that once more confirmed to be a perfect choice to have good-looking and functional, vital, websites.


For the template I choose the free (as in speech) Squirrel theme released from InkThemes, which is a feature-reduced version of the full premium themes. But this didn’t worried me since the good design and code it sports in the free version. Also the static home page layout of the theme is really eye-catching with the right choice of opening images.

A design aware use of the widgets and some plugins made the rest possible and easily re-doable. Among those plugins I find that worth a mention are:
