This applet requires Java 1.1 support in your browser. This does not actually work to connect to obscure.org anymore, because this legacy application only uses SSH v.1, and we use only SSH v.2 now, since SSH v.1 is obsolete and insecure.
Some versions of Java before 1.6.0_15 would allow you to connect to other hosts than www.obscure.org with this applet, but newer versions bomb with an "access denied (java.netSocketPermission ... resolve" exception.
