XDMCP: For IPv6 add IPv6 link local addresses to the end of the list
|
|
|
|
For IPv6 add a link local addresses to the end of the list passed to
|
|
the XDMCP servers.
|
|
Reason: for link local addresses the XDMCP server would need to either
|
|
know the interface thru a scope identifier or try all available interfaces.
|
|
If they don't this address will fail in which case the XDMCP server
|
|
could still try the other addresses passed - however some only try
|
|
the first address and then give up.
|
|
Even if this seems to be the wrong place to fix this it seems to be
|
|
easier than fixing all display servers.
