X-windows exercises:
X-windows allows you to use a remote computer (examples: "roxi.rz.fh-mannheim.de" or "clone3.mcb.uconn.edu") with a graphics user interface. This remote computer is called a client, programs you run on this computer are called client programs. These client applications need to be designed to use x-windows. Often your local pc (the server -- I know, usually the terms are used the other way around, but I can't change it) is set up to log into a client and start some client applications automatically.
Setting up a client is easy. You need only two commands:
1.) tell the client to direct the display to your local PC;
2.) Start your client application.
One way
to do this is to use telnet, and an X-windows server in parallel.As a rule this is more reliable than to launch applications menu from within the X-windows server (the latter is faster though, if it works).
Launch the x-Windows server by double clicking. If it opens some default client you can close the client, but leave the server running.Telnet to your client
(roxi.rz.fh-mannheim.de) and tell it to export the displayfor unix
ksh the command is:
"seaview &" or "phylowin &" (the & put the application into background)
Possible client applications on UNIX are (I have no idea is these are availabe on ROXI):
"xclock &"
(the space & after a unix command makes this command run in background, in this case the clock keeps on running until you close the clock window)"dtpad &" -
this starts a text editor on the UNIX machine. This comes in handy if you want to modify a file without FTPing it back and forth to your local PC."aixterm &";"xterm &"
: terminal windows (instead of your telnet window)"info"
start information/help program"xcalc &"
start a pocket calculator application"xmaple &"
starts a symbolic math computation pack"xman"
UNIX manual"xloadl"
starts loadlevel batch program manager"mathematica"
starts software package
