I have built an application that needed to communicate with another Linux server. It was very simple commands that my nodeserver should receive.

To get the POST-variables in the in-built HTTP-server from NodeJS you can use this method:

function onRequest(request, response) {
  var pathname = url.parse(request.url).pathname;
  console.log("Request for " + pathname + " received.");
  response.writeHead(200, {"Content-Type": "text/plain"});
 
  post_handler(request, function(request_data)
   {
	console.log(sys.inspect(request_data));
	response.end();
   });
}
function post_handler(request, callback)
{
    var _REQUEST = { };
    var _CONTENT = '';
 
    if (request.method == 'POST')
    {
        request.addListener('data', function(chunk)
	{
	    _CONTENT+= chunk;
	});
 
	request.addListener('end', function()
	{
        _REQUEST = querystring.parse(_CONTENT);
	    callback(_REQUEST);
	});
    };
};
 
http.createServer(onRequest).listen(8888);

Unfortunately OSX doesn’t use .bashrc per default, but it is easy to enable it. To do it, open up the file /etc/profile with root privileges like this:

sudo nano /etc/profile

And add the following line:

[ -r $HOME/.bashrc ] && source $HOME/.bashrc

As mentioned earlier I am doing a lot of traveling at the moment, which means that I am mostly on a mobile connection.

I needed to download a 100Mb file from my Linux server, and with scp the download would fail.

Instead I am now using this rsync command that would resume if the connection drops:
rsync –partial –progress –rsh=ssh root@rauw.dk:filename.exe filename.exe

Also, if you are using SSH on a slow connection, typing things make lag, you can use this command:

rlwrap -a ssh user@address

I am currently sitting in a position where the only way to get internet is through a mobile connection. This means that large downloads often are not possible because of the connection drops.

I needed to download a 500 mb file from RapidShare, that does not allow resuming of download after a connection drop (at least not for non-paying users). My idea was to let my server download the file and to let me download it afterwards with resuming.

The only problem was: The captcha since my server isn’t running a graphical user interface.

I found a program called Plowshare, that can download from a lot of download-websites, and send the Captcha image to my computer through the X11 connection.
