Is that the full comamnd line?

Errr, well, you have to ask for some channels!

Yes, again I can't see the full line from this, but you should be
naming the channels you want here. Something like:

 ./nbd-client 129.120.220.38 1077 129.120.220.38 129.120.220.38 129.120.220.38 129.120.220.38 -b 1024 -t 120 /dev/nda

That might be something else. The setup was already hosed by the 0
channels, but it shouldn't be doing this.
