Thanks Nadappan,
I think the firewall is not the problem because it makes no difference
if I disable the Windows firewall completely.
Can it be that ldtp version 2.3.1-1 (on the Linux PC) is incompatible
with version 4.0.0 of CobraWinLDTP ?
When I set LDTP_DEBUG=1 on the Windows machine, I can see that there is
communication between the two machines as soon as I execute "from ldtp
import *" on python on the linux PC:
8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------

This is what I see on the Linux machine:
8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------

$ export LDTP_DEBUG=1

By the way, I have installed python on the server (Windows machine) and
I can execute the same test locally on that machine successfully:
8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------

'gvim', 'sh']
>>>

So it looks to me like it is just an incompatibility between ldtp and
cobrawinldtp. Can this be?
Many thanks,
Thomas

Hi Thomas,
You can set the following environment variables on Windows box:
set LDTP_DEBUG=1 # If you need debug output printed on console
set LDTP_LISTEN_ALL_INTERFACE=1 # If you need to listen other than
localhost, default is listen only on localhost
On Linux side:
export LDTP_DEBUG=1
I tried your scenario after setting above environment variables. More
over, have enabled inbound firewall rule on my windows box to accept
request on port 4118. Everything worked as expected.
Side note: I tried LDTP git head on Ubuntu 13.10.
Thanks

Hi,
I get the following error when I try to connect from a linux
machine to a windows machine:
xmlrpclib.Fault: <Fault 0: 'Request contains too many param
elements based on method signature.'>
On the server (windows XP machine called xp-pc) I am doing this:
CobraWinLDTP.exe
On the client (debian linux machine) I am doing this in a bash shell:
export LDTP_SERVER_ADDR=xp-pc
then:
python
>>> from ldtp import *
>>> getapplist()
The client can connect to port 4118 on the server no problem, but
the server appears to somehow not understand the request from the
client. I downloaded a copy of VisualUIAVerify, and it can see the
windows programs running no problem.
I used wireshark to capture the RPC transaction from TCP/IP and
this is what I got:
8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------
>From the client (Linux PC):

</fault>
</methodResponse>
8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------8<----------
So it looks to me like the RPC communication is fine.
I installed Cobra-winldtp using CobraWinLDTP-4.0.0.msi from
http://code.google.com/p/cobra-winldtp/
On linux I have LDTP version 2.3.1-1 installed (Debian).
Can anyone help, please?
Many thanks,
Thomas
