Solve the problem that Dropbox cannot be connected

Let's take a look at http: // 114.215.115.165/

The synchronization and sharing service Dropbox was blocked again since January 1, June 18 because of DNS pollution. Dropbox was blocked by IP addresses and URL keywords last time in May 2010. In May 2012, all functions except the file chain function were accessible. In February 2014, all functions were accessible. The file sharing service is an important goal for China's ongoing net operations. However, it is still unclear how this operation affects shared services outside China. The Dropbox domain name is vulnerable to DNS contamination, and the Dropbox domain name is also blacklisted, making the Dropbox client unusable.

There are two reasons why Dropbox cannot be connected. One is that the connection between you and the server is blocked, and the other is that your DNS request is contaminated, a nonexistent destination is returned. Dropbox cannot be accessed because of the latter and DNS pollution. Because the connection to Dropbox is not wall, as long as you get the correct DNS query return value, you can synchronize Dropbox normally.

It is rumored that the modification of the hosts file can make Dropbox continue to work normally. I have not tried this method yet, but it seems troublesome.

There is a software that can solve this problem. The software dnscrypt released by opendns can encrypt DNS requests and responses to ensure that DNS return values are not tampered with or contaminated, so that we can get the correct DNS query return values. The software includes Windows and Mac OS versions, as shown below:

In addition, Windows download can also through: http://shared.opendns.com/dnscrypt/packages/windows-client/DNSCryptWin-v0.0.6.exe

The following uses Windows as an example. After installation, you can directly use it without any further configuration. A green light indicates that the DNS query connection is protected. By default, the query request goes through UDP. If you want to select "dnscrypt over TCP/443", TCP is more stable and slow. As shown in

Another big solution is to useWall-mounted VPN:

1) Rent a server outside China and install VPN

2) each machine in the partner is equipped with a VPN
