Speed Up SSH Connections

If you are working with a remote server using SSH, which requires frequent connections you might have noticed how it takes a lot of time to establish a connection. You also have to enter password every time you connect.

You can speed up this processes by configuring ssh to reuse connection to the same server if its has a connection already established.

This is a feature of OpenSSH, which I have tested on Snow Leopard and Ubuntu.

As per manual,

Enables the sharing of multiple sessions over a single network connection. When set to “yes”, ssh(1) will listen for connections on a control socket specified using the ControlPath argument. Additional sessions can connect to this socket using the same ControlPath with ControlMaster set to “no” (the default). These sessions will try to reuse the master instance’s network connection rather than initiating new ones, but will fall back to connecting normally if the control socket does not exist, or is not listening.

In order to configure, create or edit ~/.ssh/config file and add following lines –

Host *
ControlMaster auto
ControlPath /tmp/%r@%h:%p

In order to test above, you can use -v while using ssh command. This will print debug information message while establishing a connection. While using ControlMaster you will notice that the there are lesser messages.

debug1: auto-mux: Trying existing master

If you don’t want to reuse existing connection you can use ssh with -S none which will create a new connection.


Gentoo XGL – Mac OS X and Vista Killer

One of the sickest things to hit Linux “since the blinking cursorâ€?, Gentoo XGL is a hot new Live Linux disc which demonstrates some pretty crazy new concepts.

After watching the video I think we can all agree that OSX needs to watch out, and right now Vista doesn’t seem to stand a chance.

When Linux gets inspired by Mac OS X

Novell has just presented the next version of their NLD
(Novell Linux Desktop). The Novell distribution is based on SuSE Linux.
Multimedia management has been developed for this release, particularly
support for the iPod Nano (thanks to a mp3 player which was developed
in-house and has been released as OpenSource), as well as cameras where
in a few clicks photos can be published online.
But the biggest surprise is the new graphic interface which uses OpenGL
to create effects which you are all too familiar with, like window
transparency, switching desktops using a large rotating cube, or
creating a thumbnail view of a window.

Guide to Window Managers

One of the guiding philosophies of The X Window System (and also UNIX itself) is that its functionality is achieved through the co-operation of separate components, rather than everything being entwined in one huge mass (or should that be mess?). The advantage of this is that a particular part of the system can be changed simply by replacing the relevant component. The best example of this is the concept of a window manager which is essentially the component which controls the appearance of windows and provides the means by which the user can interact with them. Virtually everything which appears on the screen in X is in a window, and a window manager quite simply manages them.

KDE vs. Gnome

Indepth comparison, which is best for you? “One of the most common questions people new to Linux ask is ‘Should I use KDE or Gnome?’ ”



Cooperative Linux

Cooperative Linux is the first working free and open source method for optimally running Linux on Microsoft Windows natively. More generally, Cooperative Linux (short-named coLinux) is a port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine. For instance, it allows one to freely run Linux on Windows 2000/XP, without using a commercial PC virtualization software such as VMware,
in a way which is much more optimal than using any general purpose PC
virtualization software. In its current condition, it allows to run
the KNOPPIX Japanese Edition on Windows.
