Some Tips for Passwords and Logins

Legend:

  • R : Root, user role
  • S : System Accounts
  • U : User Accounts

In general order of increasing security.

Do not send passwords in clear text over the network

[RSU]

As a general rule no protocol that transmits unencrypted authentication data over a network should be used. Examples of insecure protocols are telnet, ftp and the r* tools. All modern Unix and Linux systems ship with secure alternatives as default, and either no longer contain or require manual intervention to enable legacy protocols.

Where legacy applications demand use of insecure protocols, [continued…]

Start X

Starting a Window Manager

When the idea of a graphical system for Unix was first introduced, there was a basic (very basic) graphical screen, based on what some of you will recognise as xdm. That is all well and good, but for those of us that like the CLI (Command-Line Interface), you can use:

startx

to force a normal console-login to start your desired window-manager. Graphical login managers use the underlying configuration file:

~/.xsession

While startx uses:

~/.xinitrc

Although, if no ~/.xinitrc file is present, startx will read ~/.xsession quite happily.

Initially (unless you have added one to /etc/skel/), these [continued…]

    Multimedia keyboard hot keys

    Introduction

    A lot of keyboards now have multimedia hot keys on them. For example, most of the Logitech keyboards have the ability to mute the sound and turn the volume up or down. It is possible to use them under X on Linux.

    Keyboard keys pass through a ludicrous number of different remappings on Linux before X applications receive them.

    But they’re not “remapped” at all. The XServer has to communicate back to the XClient (via the window manager) the key that was pressed. This isn’t remapping whatsoever.

  • The keyboard generates scancodes
  • The Linux console driver remaps these to Linux [continued…]
  • Qemu Tips

    Qemu Video Performance

    To optimize video performance under Qemu you should use a 16-bit colour depth on both the host and guest operating systems. To set 16-bit colour depth do:

    $ sudo gedit /etc/X11/xorg.conf

    Find the line which starts ‘DefaultDepth’ and change it so that it reads…

    !DefaultDepth 16

    Remeber to restart X in order to make your changes take effect.

    Qemu Launcher
