Putty Tunnels and Accessing remote IP blocked via firewall

This article will show step by step instructions How to setup tunnelling in Putty . This is extremely useful if a port is not opened over firewall but you can hop to a server with access and from there you can hop to another and so on.. Essentially it forwards port if you have access to atleast one port. Create a new SSH session - and save it. And click on load to load the settings. Choose the server and port  where you have already got access and firewall works. (eg.  ServerA, Port: 22) Select Tunnels from the Left Menu, specify the Source Port and Destination: The tunnel is created between the REMOTE UNIX box and your local machine (localhost). So, the source port will be the port on the REMOTE UNIX box  to which you want to talk to at a specific port which you can't access (eg Port 37150). And the destination will be your localhost, which will act as the other end your tunnel session [ad#ad-3] Click Save after selecting the"Session" Open the saved sessi

How to revert back to google docs from google drive?

Many of us must have faced issues of corporate firewall blocking URL's like drive.google.com, dropbox etc. I changed from google docs to google drive recently and found that my company have blocked "drive.google.com". Whatever you try, google redirects your URL to "drive.google.com" and there is NO HELP from our network adminstrator. My scenario is 1. Google Drive -> blocked 2. Google docs (docs.google.com) -> OK 3. Google won't allow to switch back to old google docs URL  (Hence using Temporarily classic looks fails) !! I couldn't find a technical solution yet. But found a workaround .. a)  Create a new gmail address or use another gmail address but DO NOT enable google Drive. Hence use old google docs in that.  (let's say  SECONDACC ) From your original (problem facing) google drive, create a new folder and share the folder and its contents with SECONDACC . This needs to be done at somewhere you have complete access outside corporate fir

Proxy Server and its uses

I used to use many public proxy servers for accessing sites which are blocked by intranet or restricted sites. But recently the company policy started to block many of the public proxy sites, thus pushing me back to square one. !! I saw a great article from Amit (labnol) , to setup a proxy of your own !! That's really cool. That link gives step by step instructions to setup your own proxy server within "appspot"  , i.e. google app engine site. You could try out one sample at :  http://whatitem.appspot.com (if you really can't setup your own) You could give your URL directly by appending it to the proxy application .. eg  http://whatitem.appspot.com/google.com DON'T try to include keyword Proxy in your app address as most of the intranet filters checks for those keywords.
