1. get http://phpxmlrpc.sourceforge.net/
(is the library used on TestLink to implement XML-RPC client with HTTPS support - see http://mantis.testlink.org/view.php?id=4224)
This way you can use the XMLRPC debugger to test your connection to Trac
Hint with debugger: after fresh install you need to copy content of lib folder on debug folder
2. You can get a Trac appliance from TurnKeyLinux.
This example has been done using appliance available @2012-08-26
* login into appliance and then:
* #trac-admin /var/local/lib/trac/hg-helloworld
* Trac [/var/local/lib/trac/hg-helloworld] permission add anonymous XML_RPC
* Trac [/var/local/lib/trac/hg-helloworld] permission list anonymous
3. with debbuger if you gethttps://docs.google.com/open?id=0B-hNfK ... VNXLTRNSWc,
you can try to continue integration with TestLink.
