Re: XMLRPC Client error

Hi Muhammad,

not a great programmer here, but seems that the target machine is the problem.

IMO two possibilities, I see you are on a WIndows machine:

• firewall issues ( on the target AND/OR on the source machine)
• wrong settings in the sockets ( port mismatch ?)

In my experience the XMLRPC scenario it's simple and well documented, but not so 'responsive'. Switching to ZMQ socket ( in this specific case the PUSH/PULL pair seems adeguate) I found that everything works much better.

My 1 eurocent :-)
