remote data

[Ramon Solano]

Hello Teresa,

I haven't use the remote server capabilities of GrADS, but I usually  
work with secure connections for several other applications (such as  
IDL-ENVI, X-11, VNC and others). The trick is to create a secure  
"tunnel" (with SSH) for the ports you need between your computer and  
the server.

For example, if you want to connect to a VNC server, say, display :1  
(port IP 5901), you first need to create the tunnel:

    ssh -L 5901:server:5901 user at server

then you can connect your VNC client to localhost:1 (local host port  
5901), which is tunneled trough SSH to your server:1. You can use more  
than one -L in the command line for tunneling several ports at once.

I hope this example gives you an idea about how to use it for your  
purpose.

Cheers,
Ramon
