ANONYMOUS wrote The simplest approach, avoiding the problems you've identified with detecting if the channel is in use, and collating the utilisation from each node, is to follow the same approach discussed in Q1 of Tutorial 3.

ANONYMOUS wrote The emphasis is on the word 'semantics' - how things must work as expected. For example, authentication is not required for a file-system to work as expected.

ANONYMOUS wrote Glad that something's working for you, though I can see how allowing the select() call to unblock after 10sec would help the datagrams arrive. It sounds like you don't have all the important descriptors set in your readset .

ANONYMOUS wrote The fastest journey is one that arrives at the destination soonest - even if you have to wait around at the starting platform before the first leg.

ANONYMOUS wrote Yes, that's exactly as expected. That is what the web-browser is sending the the 'nc' process, which is listening on port 4444. Probably because you're missing the colon before the 4444.
