- I get the error
wpcap.dll not found.
You need to install
WinPcap.
- How do I determine what interfaces I have? Pass the command line option
-i help
- I have multiple network interfaces and STUNT always reports
an error. Pass the command line option
-i
help to list the interfaces and then execute STUNT with -bftro
output -i <num> where <num> is the number of the
interface that connects you to the internet.
- I get the error -- "Need root privileges". On Windows, you need to run the NAT testing utility while logged in as an
Administrator. On Linux, you need to run it with an effective user ID of
0. The NAT testing utility needs these privileges since it needs to see the packets sent by the
operating system.
- I see lots of errors. Is something wrong? Intermittent errors may occur, if so, try running the client after a
while. If the error is persistent then there may be a problem. Please run the
client with the
-vv option, redirect the output to a file and
contact saikat@cs.cornell.edu
with a copy of the output for diagnosis.
- How much CPU time and bandwidth does this use? The client uses virtually 0 CPU time since there is negligible
processing required. It uses less than 0.05 kbps on average since TCP
connection establishment involves very few packets and very little data is
transferred between clients and servers.
- The test always errors while testing bindings. Some NATs, like Open BSD, enforce TIMED-WAIT state after a connection
is closed by a RST even if the client operation system doesn't. Try passing the
command line option
--binding-interval 120. This will make the
test take longer, but it will hopefully succeed.
