I am preparing a class in Computer Networking for a group of students at an industrial site. I'm comfortable with deluging them with lots of reading and lecture, but they're expecting some lab work as well. It was said that they would like to "write a server." I've taught this material to undergrads before, and have observed that writing a simple client (like a UDP echo client) from scratch can be challenging enough. The rub in this case is that the only machine to work with for class purposes is *not* networked, apparently for security reasons. So: does anyone have any sort of network simulation code that would allow students to observe/fiddle with/write network-like code on a single machine? It's running a BSD/Unix variant. (How I can get the code onto the machine is another story . . .). Thanks, - RL "Bob Morgan

One can write network applications local to a single BSD machine. Just use the loopback interface and address (usually 127.0.0.1). -Ron
