Xen users - Nov 2007 - about xen xmlrpc-tcp-server

Hi all,

    Now I have some questions about the xen''s xmlrpc-tcp server and
XenMan''s remote management.

    Q1. I have modified the /etc/xen/xend-config.sxp as follows:
        (xend-tcp-xmlrpc-server yes)
        (xen-tcp-xmlrpc-server-address ''localhost'')
        (xen-tcp-xmlrpc-server-port 8006)
        (xend-address '''')

        So I have open the xmlrpc-tcp server, and I can get correct result with
"netstat -a|grep 8006".
        If I use "telnet localhost 8006", it is ok. It gives me the
information as follows:

        Try 127.0.0.1...
        Connected to localhost.localdomain (127.0.0.1)
        Escape character is ''^]''

        But if I want to use "telnet 172.19.11.14 8006" (assumed my
machine''s IP is 172.19.11.14 ), it is error:

        Trying 172.19.11.14...
        telnet: connect to address 172.19.11.14: Connection refused
        telnet: Unable to connect to remote host: Connection refused

        Why? Because of authentication? Or else?

  Q2. In /etc/xen/xend-config.sxp, there are
        #(xend-tcp-xmlrpc-server-ssl-key-file  /etc/xen/xmlrpc.key)
        #(xend-tcp-xmlrpc-server-ssl-cert-file /etc/xen/xmlrpc.crt)

        Is it implies that xend use ssh as its xmlrpc server''s
connection protocol?
        Can change it to traditional telnet protocol, though telnet is not
security?

  Q3: I am trying XenMan v0.6 to manage remote xen hosts, but I meet some
problems.
        When I use xenman to connect remote host, it always tell me that
        no element fount: line 1, column 0

        I try to debug the source code, exception are 
         File "/usr/lib/python2.4/xmlrpclib.py", line 527, in feed
           self._parse.Parse(data,0)

       I debug XenNode.py separately
......

if __name__ == "__main__":
    host = "172.19.11.14"
    username = ''root''
    passwd = ''XXX''
    
    managed_node = XenNode(hostname=host,
                           username = username,
                           password = passwd,
                           isRemote=remote)

   managed_node.refresh()

   And it can get the correct result.
   Moreover, I have added some debug code in remote host''s xend source
code,
   remote xend always can give the ecorrect domains'' information.
   But why I cannot get correct one?

   I use CentOS 5, Python 2.4, Xen 3.1 Paramiko 1.7.1, pycrypto-2.0.1

Q4: Can I use normal telnet while not ssh as XenMan''s connection
protocol? If Xen allow that.



How can I solve the problems?

   Thanks a lot.

Maybe it''s the above line which explicitely tells the server to bind to
the
localhost interface?

Dear  Frank Burkhardt,

No. Even I change the ''localhost'' to server''s IP such
as "1.2.3.4",
the server just can receive the 127.0.0.1''s connection, IP''s
connection is still refused.
I feel so puzzled and still cannot know the reason!!
