FREE SSH Tunnel – An Alternative to VPN

SSH, the Secure Shell, is a standard protocol that encrypts communications between your computer and a server. The encryption prevents these communications from being viewed or modified by network operators. SSH can be used for a wide variety of secure communications applications, where secure log-in to a server and secure file transfers (SCP or SFTP) are the most common. SSH is a good alternative to VPN.

SSH is especially useful for censorship circumvention because it can provide encrypted tunnels and work as a generic proxy client. Censors may be reluctant to block SSH entirely because it is used for many purposes other than circumventing censorship; for example, it is used by system administrators to administer their servers over the Internet.

Using SSH requires an account on a server machine, generally a Unix or Linux server. For censorship circumvention, this server needs to have unrestricted Internet access and, ideally, is operated by a trusted contact. You can get a free SSH account from Visit and register a SSH account,then you will receiving an email asking you to click the link inside for activation your account. After clicking the link, you will receive a second email soon containing hostname, username and password for SSH in the email.
