How to encrypt HTTP traffic (and bypass most firewalls) using SSH Tunneling with PuTTY on Windows

Posted on September 4th, 2008 webmaster No comments          Print

I’ve been using SSH Tunneling for a while now mainly to encrypt HTTP traffic when using public wireless access points.  I won’t go into detail here, just Google for “SSH Tunneling” if you need more information.  I’m also gonna assume you already have an SSH Server set up.

• Download PuTTY and save it to C:/.
• Open notepad, type in the command below and save it as securetunnel.bat (Note: remove username@ and -pw passwordif you prefer to get prompted for them for security reasons):
  • c:\putty -D 8080 -P 22 -ssh username@ssh_server_ip -pw password
• Double-click securetunnel.bat to connect to your SSH server.
• Open your internet browser and change its proxy settings to use 127.0.0.1:8080 as the SOCKS host.  To do this in Internet Explorer 7, go to Tools -> Internet Options -> Connections Tab -> LAN Settings -> Check “Use a proxy server for your LAN…” -> Click the “Advanced” button and set the settings just like the picture below:”

• Go to http://www.whatismyip.com and if your public IP shows up the same as your SSH server’s public IP then you’re all set!

VMware ESXi First Impressions

I finally got a chance to try this out yesterday on a Dell PowerEdge 6600 server that we use for testing at work.  I’ve been testing it pretty much most of yesterday and today and I have to say that I’m very impressed with it so far.

Installation was very easy: download and burn the ISO image, boot from it, follow the installation instructions on the screen (which is pretty much next, next next), set the root password, and set a static IP address if you want.

To manage it, open your web browser, point it to the IP address of the ESXi server, download the free VMware Infrastructure Client from there and install it on your computer.  You pretty much do everything here: creating and managing virtual machines, data stores, upload/download files, resource allocation, etc.

VMware also has a very cool free tool called VMware Converter for converting physical machines, backup images, and other virtual machine formats (such as Microsoft Virtual Server 2005) to VMware virtual machines.  You can run this while the machine you’re converting is running and you can even convert the machines directly to the VMware ESXi server! Very cool!

So far I’ve converted a virtual machine created by VMware Server and our physical desktop deployment server (BDD 2007) and they both converted successfully with no problems.

I’ll be doing more testing this week and we’re most likely going to be moving our production servers running on Microsoft Virtual Server 2005 R2 and other physical servers to VMware ESXi.  It’s pretty much a no-brainer, especially since ESXi is now free.
