What if Dropbox can't connect?

What if Dropbox can't connect? Dropbox can't land what's the solution? Synchronous Shared Services Dropbox has been blocked again since June 18, due to DNS contamination. Dropbox last in May 2010 was the IP blockade and URL keyword filter, in May 2012, in addition to the outside the chain of functions other functions can be normal access. All functions are accessible in February 2014. While China is launching a net-net operation, document-sharing services are an important goal, but it is not clear how this action affects foreign shared services, and officials have never had an explanation for the blockade. Dropbox domain name lying gun-like DNS pollution, and Dropbox domain name also entered the Blacklist keyword, resulting in Dropbox clients can not use.

Dropbox can not be connected, known for 2 of reasons, one is that your connection to the server was wall; the other is that your DNS request was contaminated and returned to you with a non-existent destination. Dropbox is not accessible because of the latter, DNS pollution. Because the connection to the Dropbox is not wall, as long as you get the correct DNS query return value, you can synchronize the Dropbox normally.

There are rumors that by modifying the Hosts file method can let Dropbox continue normal use, I have not tried this method, but this seems more troublesome.

There is a software that can solve this problem. OpenDNS released software Dnscrypt, can encrypt DNS request and return, guarantee the DNS return value not to be tampered with and pollute, let us get the correct DNS query return value.

The following Windows version of the installation as an example, after the basic installation is not how to configure, directly can be used, the green light means that the DNS query connection is protected. The default query request is to go UDP, "Dnscrypt over tcp/443" Want to choose, TCP more stable, but also more slowly. As shown in the following illustration:

And a tall solution is to use a VPN to get through the wall:

1 Rent a server in the outside to install VPN

2 Every small partner's machine is equipped with VPN
