In a previous post Access data behind your Firewall from inside the customer’s location I wrote about getting to my data that was behind my company firewall while located on the inside of my customer’s network behind their firewall/proxy server. This was accomplished by using a program called Tunnelier from a company called Bitvise. Tunnelier allows you to create an SSH tunnel through the local web proxy and over to my company SSH Server, while on my local laptop it starts a SOCKS proxy for local programs (like IE or Firefox) to connect to and thus be able to reach my company’s data while remote. A problem arises though when the program that you want to use….most notably Opera Web Browser in my case…does not support the use of SOCKS. Well, there’s a solution to this problem called ProxyCap. It will “Sockify” programs that are opening an outgoing IP connection and redirect it through a proxy. In my case I’m having it redirect to the local SOCKS proxy that Tunnelier has created locally.

So, to continue where my last article left off; To get Opera to use your SSH tunnel, you need to:


1. Define your local SOCKS proxy In this case I have defined a SOCKS v4 proxy on localhost (127.0.0.1) port 8081(I did have the port at 1080 in my last article, but had to change it to resolve a port conflict with another app I was running). Be sure and use SOCKS v4, and not SOCKS v5 as the current version of Tunnelier (11/2007) seems to have an issue with killing the SSH tunnel when too many SOCKS v5 clients are talking to it. SOCKS v4 does not exhibit this issue.

Android: The next Linux?

5 November 2007

As you may have heard, Google today announced its much anticipated mobile phone initiative know as Android. Today was just the announcement….no handsets to show off, no cools apps to see, but there sure is a lot of talk about it already.

I was looking at it all and I kept coming back to the thought that this might be the Linux of the cellphone industry. [And yes, I know Linux runs on a couple of handsets already, but that's not the point I'm trying to make.] Before Linux, users really didn’t have any other choice for an operating system on their new computers….it was Windows or nothing. Then Linux came along and those with the technical savvy could run software that was free. Now a days there are plenty of articles out there about how close Linux is coming to being able to replace Windows as the operating system of choice for businesses. Granted its taken years to get here, but here we are anyway. Now we might have the same kind of software in Google’s ‘Android’ in that its Open Source, free to anyone who wants to load it, and it allows any developer to write code for handsets (and it also is based on Linux).

I don’t think for a minute that everyone is going to rush out and get these phones. For the vast majority of business users, I would surely recommend that you don’t go for the first wave of these things, as there are going to be many technical issues that could cause loss of phone service. Wait a while for things to sort themselves out, or for when you see a new application that you can’t get on your “normal” handset. I plan to get one of these to play with….but its not going to be my business phone! …at least not to start with ;)
