Your question is unclear, please clarify. Do you mean you want a server to run an application on a client machine? What programming language? What environment? What version/distro of Linux? You need to provide more information before you can get meaningful help.

remote execution
 

I want such a code so that from the server I can invoke a process i.e. execute any program in a remote client...
but I will not be able to use IP address so ssh cant be used......

so plz help me out.....

.....thanx in advance........

If you can't use TCP/IP, not sure how you expect to run ANYTHING remotely. You could write a program to listen for UDP packets, I guess, and act accordingly, but then you'd have to have it plugged in to the network, so why not just use TCP?

I think you need to carefully consider what you're trying to do, and what methods are best to accomplish it.
