cl> stty gterm cl> reset node = hostname!to tell the remote IRAF that it is talking to a gterm window and that the image display is on the network node hostname. Note that in V2.10.4 and later versions of IRAF the trailing "!" is required to distinguish logical node names from other environment definitions.
In this mode one is effectively using the workstation as a sort of super terminal with powerful graphics and image display capabilities. One gets the best of both worlds, i.e., a state of the art user interface, and the compute power of a large machine. It matters little what operating system is used on the remote machine, so long as it also runs IRAF. Except for the details of the login sequence, operation is completely transparent; gterm does not care whether the process it is talking to is on a local or remote node. Performance, e.g,. for image loads, is often better than when everything is run directly on the local node, due to the more powerful server.
