Torbutton for Firefox 4

Torbutton is a 1-click way for Firefox users to enable or disable the browser's use of Tor. It adds a panel to the statusbar that says "Tor Enabled" (in green) or "Tor Disabled" (in red). The user may click on the panel to toggle the status. If the user (or some other extension) changes the proxy settings, the change is automatically reflected in the statusbar.

I lately upgraded my firefox 3.6 to firefox 4 and so far it looks pretty good and I am having fun with the new firefox. But many of the old add-ons were not working and I had to upgrade them as well. Among them, torbutton was also not working so I checked the mozilla addons site but apparently didn't find any update to it. I could each time edit the network preferences to set the proxy but I am too lazy to do that always so checked the torproject site and found new release of torbutton.
Torproject has released alpha version of new torbutton that will work for firefox for now. Though its still in testing phase and might need to be worked on, we can still use it and seems to work well except I can't see the menus properly when I right-click on the torbutton icon.

To download and install torbutton in FF4, Click Here. Btw, the new add-on manager makes the installation process pretty simple and sleek.

Passing variable/arbitrary number of arguments in PHP

Sometimes, we might need to pass arbitrary number of arguments in PHP and probably we might have been using the option arguments feature of PHP for this purpose but we have got yet another function that can be utilized for passing arbitrary number of arguments to your functions.

func_get_args() is a very useful function available to achieve the passing of arbitrary number of arguments. The function returns the array of the arguments passed to the function. The following sample code will clarify.

<?php
function func()
{
 $args = func_get_args(); //array of the arguments passed to the function
 //now we could do anything with them..
 
 foreach ($args as $key => $val)
 {
  echo "Argument $key : $val
";
 }
 
 }
 func();
 func("I love my Nepal");
 func("I love my Nepal", "I love my culture");

?>

Hope it helps some of you out there.

xRDP installation how to

Based on the work of rdesktop, xrdp uses the remote desktop protocol to present a GUI to the user.

The goal of this project is to provide a fully functional Linux terminal server, capable of accepting connections from rdesktop and Microsoft's own terminal server / remote desktop clients.

We can download and install the xRDP directly from the ubuntu software center under ubuntu and the source can be downloaded for other distros. After the installation, we can execute the command from the terminal as below to verify if its working correctly or not.

rdesktop 127.0.0.1

In the sunde terminals and probably in other such hardware products, we don't have to remember this command. Sunde gives us the option to choose Linux from the configuration display and that would be enough for running xRDP. And it seems to work pretty fast.

Offline version of UnicodeNepali.Com V3 Converter

Sometimes, we might need to use unicodenepali.com converter and we might not have access to the internet. But, by just saving the complete webpage of the converter, you could get the offline version of the converter. Now you can take the downloaded html and its related files anywhere and open the html file to run the converter offline.

Even better, if you are windows user, you could save .hta version from Internet explorer and could make a single file of the converter in your own computer.

Netpoint Protocol installation and setup[How To]

Recently, I and my friends had to implement netpoint protocol to setup the server/client eLibrary environment in one of the schools in Nepal. In this post, I will list the steps to follow while setting up such terminals. By the way, the terminals we used were Sunde terminals. This is pretty short tutorial without going into details because I assume that the person who performs these installation has good knowledge of how computers work.

a) Install Windows XP(or any other windows version) in the server machine

b) Select and run one of the Sunde terminal clients. Its for downloading the necessary softwares to our server machine as the necessary softwares are hosted in the Sunde terminal clients.

c) Connect the server and client with ethernet cable and set static IP address for both the server and client.

d) Run the internet explorer and type the I.P. address of the sunde client in address bar.

e) You'll find a page from where you can download netpoint setup file and user guide as well. (Also, xRDP for linux is available for download).

f) Install the netpoint setup software in your server machine and it will have netpoint protocol and netpoint management GUI installed in it.

g) Now you'll have to add users and assign the newly created users to "Remote Desktop Users" group. For that, right click in My computer -> Manage and from there, you can add users and assign them to groups from "users and groups" section. I would let you figure out how to do this. Btw, create the users with passwords otherwise you'll have to perform group policy editing to allow logging in of remote users without passwords(to do that, use gpedit.msc)

h) If you want to setup DHCP server in your server, you could do so. Otherwise setting up the static IP would be enough. Now, set the static IPs for all the clients and also set the server IP in all those clients.

Your sunde terminals are now ready to go. If you get messages like "can not connect to server", ensure that server IP in the clients is correct and also make sure the physical things such as NIC, ethernet cable, etc. are working correctly. If you get the login window and can't login with the user, make sure those users are assigned to group "Remote Desktop Users". Also, sometimes you might need to turn firewall off in the server.

I might have missed some stuffs while writing this. If you face any problem, feel free to comment. And I am sorry that I could not provide you any screenshots. Maybe sometimes later when I got the next netpoint deployment(but its unlikely). Also, you can use Linux in the server and in that case, you will have to use xRDP or any other RDP protocol server software for linux.
