Java-based GSI-SSHTerm

There is an issue with Mac OS X 10.5 (Leopard) or later and X11 Forwarding. Apple's latest X11 program uses a different method for handing X forwarding which is incompatible with the X forwarding implementation in GSI-SSHTerm. There are two solutions to this problem. The first is to install GSISSH and use it instead of GSI-SSHTerm. The second is more complex and less secure. Use it at your own risk.

1. Verify in System Preferences that the Firewall is enabled and not allowing incoming connections for X11.
2. Start X11. In the X11 Preferences, choose the Security tab and select "Allow connections from network clients". Quit X11.
3. (Re)start X11. In the xterm window that appears, run "xhost +".
4. Launch GSI-SSHTerm (either the Java Web Start version or the Java Applet version). Select File->New Connection. Select Advanced. Select the X tab. Enable X Forwarding and set Local Display to :0.0. Connect.
5. When your session is finished, run "xhost -" in the xterm window.
