with the help of the module index with search 
(http://www.corelatus.com/~matthias/modules.html) it is possible to find 
that module net_kernel handles what you want. this it the relevant paragraf:

This is done by the system itself, but the |start([Name])| function can 
also be called directly from the normal Erlang shell prompt, and a 
normal Erlang runtime system is then converted to a node. The kernel can 
be shut down with the function |stop()|, but only if the kernel was not 
started by the system itself. The node is then converted into a normal 
Erlang runtime system. All other nodes on the network will regard this 
as a total node crash.
