Link: Everything You Need to Know About the DNF Package Manager

The Fedora project has announced that the “yum” package manager will be replaced by “Dandified Yum” (dnf). Work started on dnf package manager back in January 2012 when it was forked from yum. It was made available for experimental use in Fedora 18, and work is underway to make it the default package manager for Fedora 22.

Link: Linux: Keep An Eye On Your System With Glances Monitor

Is there is a tool that can provide me a maximum of information (such as cpu, disk I/O, network, nfsd, memory and more) about my Linux/Unix server in a minimum of space in a terminal?

…..

Say hello to Glances

From the project home page:

Glances is a free (LGPL) cross-platform curses-based monitoring tool which aims to present a maximum of information in a minimum of space, ideally to fit in a classical 80×24 terminal or higher to have additionnal information. Glances can adapt dynamically the displayed information depending on the terminal size. It can also work in a client/server mode for remote monitoring.

Link: Use YUM to roll back a bad software install under CentOS/Fedora/Red Hat Linux

If you are running a RPM-compatible version of Linux that uses YUM to install software, this is for you:

Yesterday, I had a situation where a colleague experienced an issue that caused loss of audio and it seems that one of the updates which had just finished installing may have been the culprit.

Here’s where YUM shines bright and I thought I’d share a feature with you that will definitely be of help at some point. It’s the yum history feature.

It just so happens that yum while performing updates is simultaneously running a journal transaction set recording your update to a transaction id along with all of the excruciatingly painful package update and dependency information you’d ever want to know. Most of the time, you’ll never care about it. In some situations however, you may encounter a post-update problem.

The good news with yum is you have a recourse. If you need to or at the direction of your Distro’s technical support team, you may be called upon to perform a rollback.

Here’s how it works.
