None, the xterm windows are just not opening/spawning when executing mininet> xterm h1 h2
I did try mininet> h1 xterm & which interestingly opens a xterm window. mininet>h1 h2 xterm returns "10.0.0.2: No such file or directory".. So it seems it recognizes h1 at least... All others combinations (for example xterm foo1 foo2, yield "node foo1 not in network", so xterm is recognizing the nodes, but simply not spawning them when "xterm h1 h2" is executed. I tried using these "hX xterm &" windows, but the tcpdump command (next step in the tutorial) doesn't seem to be working as it should... **Since I have mininet running in two computers and both fail** I was wondering if anybody running Mininet Version 2.0.0 on Ubuntu 12.04 LTS or other ubuntu machine is able to spawn xterm consoles with this command. (Not using any VMs) Really don't know if this is a bug...
