Hey guys, anything like this on the net (with code) ??? Its urgent ! Please help me out ! What I need is a messaging system like the net-send utility in wondows which will work on linux systems. There should be a deamon which on reception of a message from a client will show the message as a pop up screen if the user is logged in a GUI window manager. In case the intended user for the message is logged into the text terminal, the message should go to the terminal which was most recently used. There will be a client program which will allow entering a message for the destined user. The client program should be commandline based but will also have GUI interface to be used if the user is logged into a graphical window manager. It will also allow to save a directory of destination users containing the IP address, machine name and login names in a configuration file. If a message reaches a destination, the destination should be able to respond to those messages.
