The Reason I Can Not Access Facebook

By Expert Author: Bob Smith

There simply wasn't enough function to, when I began my new work I'd a serious problem - boredom do
The job included switching computer tapes and discs onto a classic mainframe. It was the kind of machine that cost millions years ago, and nobody seemed to want to update it. The sum of work changed but occasionally I'd go for an hour or 2 without doing anything. It absolutely was occasionally very hard to stay awake with the hum of airconditioning and the server room making it even more challenging.
My supervisor wouldn't have minded me completing the hours by surfing the internet perhaps browsing Face Book but unfortunately it absolutely was all blocked. It was to discontinue the day staff from squandering their days, but sadly it then applied to me too.
I discovered how it was blocked, it was through a small apparatus called a content filter which also looked within the content for any requests and stopped accessibility to the Face publication URL.
The trick I discovered was to work with a combination of techniques, first you needed to use a proxy to relay your request to Fb or the blocked website. Secondly you had to use some type of encryption so that the content filter couldn't read the contents of your request. In this case it'dn't see any mention of Fb and thus permit the request.
It operates in pretty much exactly the same manner anyplace, even in those countries which are occasionally blocked from accessing sites like Facebook. Actually on a nation grade the filtering is much less advanced and simpler to circumvent.
They did so by uncomplicated DNS poisoning, when Turkey lately blocked entry to Twitter. That means that when you request the IP address of Twitter, you were given a false 1 by the ISPs DNS servers, which rather routed you through to some Government composed page. These blocks are very easy to avoid, all you need to do is use a different DNS server - something like OpenDNS. Or you can definitely avoid using others DNS servers to some extent and work out the addresses manually and pop in a hosts file. But regrettably most corporate networks are slightly more advanced than that.
anyway you'll be able to find these types of applications but sadly they are fairly expensive to operate so I did not find any free types. Everything you want though is a proxy/VPN service which allows a level of encryption - it also needs to be quick as a slight overhead is added by encryption.
