I use Ubuntu to access the Debian machine, and now my Java class is like this:
public static void main(String[] args) {
Connect conn = null;
try {
conn = new
Connect("xen+ssh://root@192.168.XXX.XX/?netcat=/bin/netcat", true);
but is still throwing the error:
libvir: RPC error : End of file while reading data: /bin/netcat: invalid option --
'U'
nc -h for help: Input/output error
exception caught:org.libvirt.LibvirtException: End of file while reading data:

I have files on the client machine that are /usr/bin/ncat , /bin/netcat and
/etc/alternatives/netcat. I am not sure which I should use.
These are actually all the same. Run "update-alternatives --display nc"
to show the current config and list alternative choices.
Installing the OpenBSD nc ("sudo apt-get install netcat-openbsd") on
your Debian machine should solve this. Just use nc.openbsd in your
connection string to make sure it is used.
