 - A functional netns binary is required to run mininet, but currently you
   have to compile it and install it yourself from the included .c file:
 
   to make it: make netns (or cc -o netns netns.c)
-  to test it: ./netns /bin/echo 
-  to 'install' a link to it:
+  to test it: ./netns /sbin/ifconfig -a 
+  to 'install' a link to it, you could do something like:
     sudo ln -s /home/openflow/mininet/netns /usr/local/bin/netns
 
   Installation is simplest with a distribution that includes a kernel
