CyberLink for Java / Discussion / Open Discussion: Multiple Devices on same Host

daniel.eggert - 2006-02-08

Should I be able to run more than one device on the same host (same machine, same IP-address).

I started the Sample Tv, and then the Sample Remote Control, but I can not control the Tv. If I start the Sample Control Point, I only see a root node, nothing else.

I'm seeing this when i start the second UPnP application:

CFMessagePort: bootstrap_register(): failed 1103 (0x44f), port = 0xfe03, name = 'java.ServiceProvider'
See /usr/include/servers/bootstrap_defs.h for the error codes.
CFMessagePortCreateLocal(): failed to name Mach port (java.ServiceProvider)

which suggests that the second app tries to bind to the same port as the first.

What should / can I do about this?

  I finally figured out, how to get this working. I had to call
  
  UPnP.setEnable(UPnP.USE_ONLY_IPV4_ADDR);
  UPnP.setEnable(UPnP.USE_LOOPBACK_ADDR);
  
  Now it works. Device get giscovered and they can talk to each other.

    Hi Deniel,
    
    I changed to disable IPv6 interfaces as default, added the change to the latest CVS source tree today.
    
    Thanks for your report :-)
