Installing SSH Server

Secure Shell (SSH) is a network protocol to secure data communication between two computer connected via network. You can access remote shell, execute command. Also using Secure file transfer protocol (sftp) you can transfer data from one computer to another. For this you need one ssh server software and one ssh client. If you are using linux then you are probably aware about that ssh client is, by default, installed. For windows user, there are lots of ssh client software for windows, you can download them and install on your computer. For example, you can use this software link, SSH Secure Shell or PuTTY.  
You can install ssh server very easily in Ubuntu. Just search for "openssh-server" or "ssh server" in your package manager and install it. Also form terminal you can run the command sudo apt-get install openssh-server . Now you can access your computer remotely and securely.
Installing ssh server in windows xp is also very easy.
For windows xp there is a very good ssh server software name opensshd. You can just download and install it. If you want to share all your hard drive just use /cygdrive/<your drive letter> in place of your sharing position option.
For windows 7 you can use copsshd. Just install it and create an user (preferably not same as windows users). Now to before start open copssh control panel as administrator and then activate the user.

Changing caption width in latex

In this post I will discuss how to change the width of the figure caption. You can use the same technique to change the width of the other caption (like table caption). Here I am using the caption package. In caption package you can specify the width while loading the package or latter using \captionsetup command. Syntax of the both command are as following \usepackage[<option>]{caption} and command for captionsetup is \captionsetup[<float type>]{<option>} In the <option> we can use width=0.8\textwidth to specify width of the caption. If we specify that in the time of loading (i.e. when using with \usepackage command) it will affect all the float (like figure, table) but if you specify it in command \usepackage then you can specify float type. Then the specific float type will only be effected. This way you can specify two different width for different float. You can also specify other kind of formatting (like italic text) usi

There is no direct command to define subtitle in latex. But you can define the \subtitle command using titling package. To do this just insert the following code in the preamble of the latex file. \usepackage{titling} \newcommand{\subtitle}[1]{%   \posttitle{%     \par\end{center}     \begin{center}\large#1\end{center}     \vskip0.5em}% } And then you can define subtitle using the following command. \subtitle{Subtitle Here} This will show the subtitle bellow your title when you use \maketitle command. Minimum working example Code \documentclass[10pt,a4paper]{article} \usepackage{lipsum} \usepackage{titling} \newcommand{\subtitle}[1]{% \posttitle{% \par\end{center} \begin{center}\large#1\end{center} \vskip0.1em}}% \title{This is the title of the document} \subtitle{This is subtitle} \author{Apurba Paul} \date{January 08, 2013} \begin{document} \maketitle Body of the document. \lipsum[1] \end{document} Output

Mozilla Thunderbird is one of the best email client available for Windows, Linux and Mac. Here I will tell how to send email in background in Thunderbird, so that when you send any mail that irritating "sending email" popup will not come out in front of you. First go to Preferences window: In windows: tools>options In linux: Edit>preferences Now go to Advance tab > General   and click on Config Editor Button, When asked click on I'll be careful, I promise button.  Then search for mailnews.sendinBackground and then select it. Then right click and toggle it to true. Now Thunderbird should send your email in background. You may need to restart the Thunderbird. Cheers A.Paul
