2) Look at the code below.  Add to it the error checking code needed

3b) What does it return on error?


4) Which of these calls puts packets on the wire?  Cicle all that apply

connect		   accept

13) 	Does traffic from here to Europe go across a satalite link?



14)	Using fork(), what does a return value of >0 mean?


15) 	In IPv4, can a source pick the exact route a packet will take?  (Hint: look up "source routing")


16)	In general, typically, normally, in the real world, which sends the fewest bytes for a user doing normal web stuff, HTTP/0.9 or HTTP/1.1?


17)	About what percent of packets are lost traveling across the Inet?



18)	If you give write a '1' where the socket would go (first argument) where is the data sent?



20)	Who stores cookies, client or server?


21)	Where in IP the packet header is the routing information stored


22)	Who has the IP address 10.X.X.X?


23)	How many computers are on the Inet?



24) What does this print
   main() {
        fork();
        fork();
        pid = fork();
        if (pid > -1)
           cout << "Cheee please\n";
