Here is an xproblem for you xgurus out there: I am logged on to a machine A (a Sun running X windows). I need to connect to a machine B from A. On B I have a process running and this process will display images on the server A. My problem is that I am unable to log into B directly from A. However, I can log into B indirectly through another machine C (that is, from A log on to C, and from C log on to B). But this causes problems since machine B now cannot connect directly to A for displaying the images. My question: Is there anyway of informing machine B that A can be reached through C? Machine C happens to be a VAX in my case - would this make a difference? I would appreciate any help. Please email responses to the address given above. Ravi

If all the machines in question speak TCP/IP, it's perfectly feasible to have a small dummy program on C which accepts the connection from B and in turn connects to A, then just passes bytes back and forth. There is a program called xscope[%] available which was designed to debug protocol problems, but can be turned to this use, or someone used to writing network applications can toss a specialized program together in short order. If you have to deal with differing or other protocols, the problem may be harder, though a similar approach should be workable. [%] There is another program called xscope available that does something else unrelated - something oscilliscope-like, I think. I don't know where either sort of xscope can be obtained, except presumably for the usual archive sites. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
