strictly speaking I have not declared a netperf-2.7 and at least as I'm 
typing am not sure if the current top-of-trunk will become 2.7.0 or 
2.6.1 (I have to see if I've changed the control messages size since 2.6.0)

BTW, in Ubuntu at least I have gotten into the habit of not apt-get 
removing the supplied netperf, but sudo service netperf stop instead, 
then build my bits and then copy the netperf and netserver binary to 
/usr/bin (where Ubuntu puts them) and an sudo service netperf start. 
That way I do not have to remember to start a netserver each time I 
reboot the OS.

I'll mention again just for completeness that a top-of-trunk 
netperf/netserver includes support for a required passphrase to be 
provided by netperf to netserver to run a test between them.  It is 
somewhat lame as the passphrase is passed in cleartext, but probably 
still better than a wide-open netserver on the Internet.

happy benchmarking,
