    2929At the moment it does not have a command line interface, and all the options have to be edited directly in the source file.
    30 One has to be very careful when interpreting the results, here are some examples of misleading statistics:

     31Note: to take advantage of iptables packet accounting (mostly for comparing with VNC which does not provide this metric), follow the error message and setup iptables rules to match the port being used in the tests, ie: by default:
     32{{{
     33iptables -I INPUT -p tcp --dport 10000 -j ACCEPT
     34iptables -I OUTPUT -p tcp --sport 10000 -j ACCEPT
