Linux: Chapter5: System Configuration from the Graphical Interface

  

          "no matter, it does not matter, as a matter of fact, what's the matter, no matter what, What's the matter?, subject matter, no matter how, matter of fact, not matter", quoted by Anonymous.

SECTION 1 Linux Filesystems

      Coordinated Universal Time (UTC) for its own internal time-keeping. Displayed or stored time values rely on the system time zone setting to get the proper time.    UTC is more accurate than, Greenwich Mean Time (GMT).

      The Network Time Protocol (NTP) is the most popular and reliable protocol for setting the local time via Internet servers. (/etc/ntp.conf)

SECTION 2 Network Manager

        You can also change the Ethernet Media Access Control (MAC) address if your hardware supports it. (The MAC address is a unique hexadecimal number of your network card.)

     Network Manager supports many VPN technologies, such as native IPSec, Cisco OpenConnect (via either the Cisco client or a native open-source client), Microsoft PPTP, and OpenVPN.

SECTION 3 Install and Updating Software

Debian Package Management

      dpkg Package Management the Debian family uses apt(Advanced Package Tool), it creates its own user interface on top of it (for example, apt-get, aptitude, synaptic, Ubuntu Software Center, Update Manager, etc).

Red Hat Package Manager (RPM)

      yum (Yellowdog Updater, Modified - the package manager used by Fedora and Red Hat Enterprise Linux), but with enhancements and changes to fit the features they support. Recently, the GNOME project has been developing PackageKit as a unified interface; this is now the default interface for Fedora.  

openSUSE’s YaST Software Management

       Apper was used for Software Management. Now it has been replaced by the YaST (Yet another Setup Tool)
