sunflower – file manager.

Sunflower file manager is a new file manager that has couple of interesting features, that I liked, not that I use graphical file managers much.

It has a in-built command line, terminal and other interesting features, so what are you waiting for just head over and download and install :

rpm -ivh

Or head over to their downloads page at :

There is still no home-page and might come soon.


Xephyr – Nested X Server

Nested X-Server is running a X server root window within your running X-windows session like Gnome or KDE. This could be useful if you want to keep all you ssh windows in one window or maybe run all you IRC, firefox, chat and others inside one window, or maybe run another window manager itself.

Lets first install ::

sudo yum install xorg-x11-server-Xephyr

Once done, you can define an alias to do the magic with your nested server. So, lets define an alias:

alias xlxc='Xephyr -title -resizeable -host-cursor -screen 1024x768 +extension randr +xinerama -ac :11.0& DISPLAY=:11.0 xterm &'

This will open a new x-server window with Xephyr and then open a terminal inside it. Once in, make sure to set your DISPAY variable in the xterm so that all other apps started from the terminal start in the Xephyr window only.

xca – Graphical X.509 certificate management tool

If you are looking for some tool to manage X.509 certificates then probably xca is your best guess. This is  a graphical tool and you can open any file and view the keys in it.

So, first install it:

sudo yum install xca

And some information on xca::

Description :   X Certificate and Key management is a graphic interface for managing
: asymmetric keys like RSA or DSA, certificates and revocation lists. It is
: intended as a small CA for creation and signing certificates. It uses the
: OpenSSL library for the cryptographic operations.
:   Certificate signing requests (PKCS#10), certificates (X509v3), the signing
: of requests, the creation of self-signed certificates, certificate revocation
: lists and SmartCards are supported. For an easy company-wide use, customizable
: templates can be used for certificate and request generation. The PKI structures
: can be imported and exported in several formats like PKCS#7, PKCS#12, PEM,
: DER, PKCS#8. All cryptographic data are stored in a byte order agnostic file
: format, portable across operating systems.
