Re: nbd-server on Centos 6.4

It turns out to be a server problem, nbd-server now works, BUT not as 
distributed;
Without changing the image I disabled the *xinetd service* nbd-server 
and started it by hand (*nbd-server 2000 /opt/ltsp/images/i386.img*). 
The client now boots.

Anyone seen similar behaviour?
