As a free AJAX SSH client, the consoleFISH provides web-based access to any SSH server. It can be used to bypass firewalls and proxies on a secure HTTP connection. Moreover, the consoleFISH makes it possible to anonymously open SSH connections as the IP address of the connecting web client is not sent to the remote system.
The service is designed for server and system administrators who want to have backup remote access to their systems but do not want to install their own SSL certificates, AJAX SSH software, etc.
