What is Jeta?

Jeta is a Java based Horde module to provide SSH login access to a web server, or to another machine if used in conjunction with some relaying software which can be installed on the web server.

Today it is recommended to use secure communications on public networks (i.e. the Internet). The secure shell (SSH) provides such secure communications, but it requires special software on the machines you are using. To avoid this requirement on the clienit machine, Jeta provides a Java based SSH application that can be accessed with any web browser which supports Java. This provides an easy to use but secure way to log into your web server with a very nice terminal emulator, all right from your web browser.

Important Security Note: The applet is suspectible to the man-in-the-middle attacks. We cannot avoid this. We can't even use the RSA based host authorization since the applet itself is downloaded from a remote host and might be modified by the man-in-the-middle. The only way to guard against applet modification would be having it signed with a trust certificate, but this is too expensive (in time, money, and development costs) to be practical. To summarize, this applet provides good security through encryption to prevent normal packet sniffing, which prevents the most common and easiest security attacks, but cannot prevent more complex security attacks like man-in-the-middle attacks.

Note: This version should run with all runtime environments that are at least Java 1.1.x compatible. If you are working with an older Java runtime environment (e.g. 1.0) please upgrade to a newer version.

What does it require?

Jeta requires a web server running Horde and a web browser with support for at least Java 1.1.
